“If you’re a man over 35 you could be losing the benefits of free testosterone, which could make you less of a man than you used to be.” Or at least that’s what’s said in the TV commercial for Nugenix, a product that—according to its TV commercial — is “a powerful all natural man-boosting breakthrough, with a unique combination of ingredients that have been clinically proven to invigorate a man’s body to increase his libido.” Those are some pretty powerful words! I first heard about Nugenix while watching the manly channel, ESPN. Fancy words aside, let’s review Nugenix and see if its right for you.
Who makes Nugenix?
On the Nugenix website (Nugenix.com) is the question “Who Produces Nugenix?” The website gives this answer:
“Nugenix is created in US laboratories under strict FDA GMP (Good Manufacturing Practices) guidelines. Our offices are in Charlotte NC as well as Boston MA. Our laboratories are in both Florida and Utah.”
Did you notice they didn’t answer the question?
What is the name of the company that makes Nugenix?
At the bottom of Nugenix.com on the “Contact us” page, I see this address:
Nugenix
MS# 730 341 W. 6100 South Murray, UT 84107
I’m not sure what the “MS” in the address stands for. I called Nugenix customer support (it’s a call center
in California) and they could not tell me either.
If you Google 341 W. 6100 South Murray, UT 84107, you will see references that this is also the address given for the arthritis supplement called Instaflex.
The link I provided shows that the address appears to be some sort of a warehouse facility. I could be wrong, but it doesn’t look like a laboratory to me. I think this is where they ship the product from.
When I called Nugenix customer support they told me Nugenix is actually produced in North Carolina.
Within the Terms of Service page of the Nugenix website, I discovered that the company that owns Nugenix is Direct Digital LLC (DirectDigitalLLC.com). Direct Digital is also the company that makes the arthritis supplement, Instaflex.
Direct Digital has offices in Boston and North Carolina. Here are their addresses:
Boston address:
364 Boylston St. 3rd Floor Boston, MA 02116
North Carolina address:
508 West 5th St. Suite 140 Charlotte, NC 28202
Click the links to see what each address looks like.
Interestingly, I didn’t see a Better Business Bureau record for Direct Digital but I did find a BBB record for Nugenix. The BBB gives very little information on Nugenix except that the business was started in 2009. There is no BBB rating for Nugenix and as of 1/14/13 and there are no complaints either. That’s good.
The Nugenix test your manhood test
The Nugenix TV commercial I saw gave men a little test to see how manly they were. The “three simple questions” they asked were:
1. “Are you losing your passion and sex drive?”
2. “Do you want to improve your performance?”
3. “How about feeling more energetic?”
Afterward, they say “Well, if you answered yes to any of these questions, you should call now to receive a complimentary bottle of Nugenix.”
Let me briefly address each of these questions to put things in perspective:
Question 1. A lot of things can cause a man to lose his sex drive. Yes, aging can play a role, but so ,too, can other things like diabetes and stress.
Question 2. What “performance” are they talking about? Are they referring to sexual performance (I think they are given the nature of question #1) or exercise performance? They don’t specifically tell us.
Question 3. A lot of things—such as carrying too much weight or even depression— can lead to a loss of energy.
In short, all 3 of these questions are vague. In my opinion, I believe they are stated vague on purpose. Asking vague questions, casts the biggest net and is more likely to get the biggest response from people.
Asking specific questions—on the other hand—reduces the number of people who might respond to them.
Tip. Asking vague questions is a common marketing method used to get a lot of people to respond.
Who is Andrea Owens?
On Nugenix.com you may see a prerecorded video of an attractive woman who calls herself “Andrea Owens.” She says ” Hi my name is Andrea Owens and I’ve got some interesting information for you…” If you watched her video, you know she goes on and on about those three simple questions I just 
discussed.”
But my question is, who is she? She says her name like we’re supposed to know who she is.
So, I became curious. If you hover your mouse over her picture you’ll see the letters “LF” appear. By clicking the little “LF” next to her video, you are taken to a website called LiveFaceOnTheWeb.com —a marketing website that puts videos of attractive people on websites. These people are called “virtual greeters“ and are used to increase website activity and sales.
You can even pick the model you want to appear on your website. If you look at the female models, you can find Andrea. She says her real name is Andrea Helfrich. If you Google her name, you see references to Miss Philadelphia 2010. I’m not sure if this is the same person as “Andrea Owens” but they both look and sound similar to me.
Marketing stuff aside, let’s now review at the science and ingredients of Nugenix and see if we can figure out what’s going on.
Nugenix ingredients
According to Nugenix.com, these are the ingredients in the product:
- Testofen (fenugreek)
- L-Citrulline Malate
- Tribulus terrestris
- Zinc: 5 mg (6.68% of Daily Value)
- Vitamin B6: 2 mg (100% of Daily Value)
- Vitamin B12: 50 micrograms (850% Daily Value)
Testofen is said to be the “main ingredient” in Nugenix. Testofen is a trademarked name for the herb fenugreek. This form of fenugreek is said to concentrate what some think are the active ingredients in the herb. These active ingredients are called Fenusides. Testofen is said to contain 50% Fenusides (pronounced phen-u-sides).
On the label of Nugenix, I see that Testofen is combined with L-Citruline malate and Tribulus terrestris to form what they call the “Nugenix Testosterone Complex.”
On the product website they say that a serving size of Nugenix is 3 capsules. Each 3 capsules contains 2013 mg of the proprietary testosterone complex. The product website also indicates that 600 mg of this complex is composed of Testofen.
How much of the Nugenix testosterone complex is composed of Tribulus or Citruline malate? They don’t tell us. I called Nugenix customer support and they could not tell me either.
Nugenix research
I searched the Nugenix website but did not see any published peer reviewed research on Nugenix itself. I also searched the National Library of Medicine for “Nugenix” and saw no research either.
Therefore, I conclude that Nugenix —itself— seems to have no published-peer reviewed evidence that this supplement raises testosterone, improves sex drive or improves energy levels. But, that doesn’t necessarily mean it doesn’t work.
So, let’s now look at the research on the ingredients in Nugenix. Here is a breakdown of the relevant research:
Testofen. This is a trademarked version of the herb fenugreek. Testofen is made by a company called Gencor Pacific. I’ve reviewed Testofen before. It is the principle ingredient in products I’ve already looked at such as:
- Ageless Male (300 mg Testofen)
- Mdrive (unknown amount of Testofen)
- Syntheriod (300 mg Testofen)
Looking at these other supplements, we see that Nugenix (600 mg of Testofen) has twice the amount of Testofen that Ageless Male or Syntheroid has. But does that mean that it works or works better?
As far as I can tell, most of the hype about Testofen seems to stem from a study published in 2011 in a Journal called Phytotherapy Research. In that study, men taking 600 mg of Testofen a day for 6 weeks reported that they felt more sexual urges, strength etc.
As I see it, the BIG PROBLEM with this study is that the men reported —in questionnaires —how they felt. Also, testosterone levels did not change. So in this study, Testofen didn’t raise testosterone levels!
As an aside, in my own little “experiment”, I tried 600 mg of fenugreek for 6 weeks. I didn’t measure my testosterone levels but I didn’t feel significantly different, like the guys in this study said they felt. Could it be because I used Fenugreek instead of the trademarked, Testofen? Maybe?
There are Testofen supplements that are sold. The online reviews that I saw at both Amazon and SwansonVitamins.com however were not completely encouraging. Still the Testofen supplement I saw pretty inexpensive.
As I summarized in my review of Mdrive, the research supporting Tesofen appears to be:
1. A human study where men basically said they felt better after taking Testofen for six weeks. This study didn’t find that Testofen raised testosterone levels.
2. A rat study.
3. An unpublished study from 2006 noting that Testofen works. I discount unpublished studies because they have not been verified or reproduced by other competent researchers. If this study was completed in 2006, why hasn’t it been published yet?
To learn more about the studies of Testofen, see my reviews of Ageless Male, Mdrive and Syntheroid.
L-Citrulline malate. This is an amino acid that we make naturally in our bodies. Other products just call this stuff “L-Citrulline.” Citrulline sometimes shows up in male sex supplements because it helps us make a gas called nitric oxide.
Nitric oxide (NO) causes an expansion of blood vessels. This is technically called vasodilatation.
The idea here is that raising nitric oxide levels might expand blood vessels “down stairs” leading to erections. This idea is not new.
One problem with trying to elevate nitric oxide levels is that the gas dissipates pretty fast. In other words, it doesn’t work for very long. For more on L Citrulline see my reviews of:
Tribulus terrestris. There are a LOT of websites saying that tribulus is a testosterone booster, but to all of them I ask “Where’s the proof?” When I look at the tribulus research, I see mostly rat studies. In my opinion, the tribulus studies that did incorporate people are pretty unimpressive.
I already reviewed the research on tribulus on this site as well as in my book about supplements so I’ll let you look at the evidence and decide for yourself. I’ll just say that based on the research I’ve seen, I am utterly unimpressed with tribulus as a testosterone booster or sex supplement.
Zinc. There is some evidence from the early 1990s noting that being deficient in zinc might cause a reduction in testosterone levels. That’s nice but my question is, are you deficient in zinc?
Foods that contain zinc include meat, shellfish, fortified breakfast cereals as well as various seeds and nuts. Do you eat these foods?
The RDA for zinc for adult men is 11 mg per day, which is not much. Therefore, I’m not convinced that healthy people who are not taking medications, are lacking in zinc —especially if they take a multivitamin that has zinc.
Vitamin B6. This vitamin is found in a LOT of foods. I don’t think most people are lacking in vitamin B6. Nugenix gives men 100% of their daily value of B6 but I have a feeling most men are already getting this from the foods they eat and the other supplements they take.
Vitamin B12. Older adults and vegetarians may be deficient in vitamin B12 as might people who take certain medications (some diabetes medications for example).
It’s important to remember that even though vitamin B12 is “water soluble,” we can store several years worth of this vitamin in our bodies! It takes a long time to run out of vitamin B12.
People generally believe that B12 gives them more energy (like caffeine). This is why there’s so much B12 in energy drinks like 5 Hour Energy and 6 Hour Power . In reality, B12 really doesn’t give you energy—like caffeine—if you’re healthy.
Tip. A quick blood test by your doctor will tell you if you are deficient in B6, B12 or zinc.
How to contact Nugenix?
To contact Nugenix the website says to call this number: 1-855-714-3234. This is actually a call center in California and not the company itself. The person I spoke with was very helpful and patient with my questions. While I was asked to try the free sample of Nugenix for $4.99, I didn’t feel pressured to do it.
I liked that.
The Nugenix autoship program
If you buy Nugenix through the Nugenix website you should read the Terms and Conditions that are listed at the bottom of the page. Here is a summary of some of the things you should know:
To get a free 14 day trial sample of Nugenix you must pay $4.99 for shipping and handling. They say it usually takes 4 days for people to get the product. So, the “end date” of your trial period will be 18 days AFTER you order your free sample. This is important.
This means that 18 days after you order the free sample, your credit card will be charged $74.98 plus tax and you will be entered into the Nugenix auto-ship program in which they will send you a 30 day supply of Nugenix every 30 days until you cancel.
To cancel the auto ship program, people must call 1-855-714-3234 at least 1 day before the next batch of Nugenix is shipped.
How to return Nugenix
It’s stated on the product website that all Nugenix auto shipments come with a 30 day money back guarantee. This is even true if the bottle is empty. Here are the basics on how to return Nugenix:
First call 1-855-714-3234 and request a Return Merchandise Authorization number (RMA number).
This RMA number must be clearly printed on the outside of the package. The package should be postmarked within 30 days of the purchase to be eligible for a refund.
Send the product to be returned to:
Nugenix
MS# 730 341 W. 6100 South Murray, UT 84107.
Nugenix will not accept any returned product that does not have an RMA number.
Make sure you get a “proof of shipment” from the post office (just in case). They do mention this tip on the Nugenix Terms and Conditions Page. They say it may take up to a month to see the refund credited to your credit card.
If you are not in the auto ship program and want to return Nugenix, the product needs to be in its original package and not opened. As before, people must call Nugenix, get an RMA number and return the product to the company before a refund can be issued.
Nugenix side effects
I’m not aware of any side effects from Nugenix. For all I know Nugenix may have no significant side effects. My gut instinct is that in “healthy people” Nugenix is likely safe. That said, looking at the main ingredients in the product, here are some potential issues that some people may want to consider:
There is some lab rat research that tribulus might reduce blood sugar levels. I’m not aware of any human research showing this. Likewise, lab rats that were castrated (ouch!) and given tribulus at a dose of 5 mg / kg per day showed an increase in the size of the prostate.
If we extrapolate this amount to people -which is not perfect- for a 180 pound man (82 kg) this equals 409 mg. That’s not much. Supplements could contain this much tribulus. What does this rat study mean for humans? I don’t know. Humans are not rats. Currently, I’m not aware of any human research linking tribulus to prostate problems.
In theory, by elevating nitric oxide levels, Citrulline might cause blood pressure to go lower. The study I liked to here involved post menopausal women. What about men? Again, I don’t know if the same thing might happen in men. I mention it in the hopes that men with high blood pressure or heart disease talk to their doctor.
Fenugrek (Testofen) might reduce blood sugar levels. This may be an issue for diabetics who take blood-sugar-lowering medications. Fenugreek also seems to have a blood thinning ability and may interact with blood thinner drugs. While for “healthy” people I don’t think this would be a problem, I do think men who take diabetes and /or blood thinner medications should talk to their doctor before trying Nugenix, just to play it safe.
Does Nugenix work?
I didn’t try Nugenix so I have no personal experience of how it makes men feel after they take it. I prefer to look only at the research. The big question is does Nugenix raise testosterone levels? Well, if I only look at the research on Nugenix, I don’t really see anything new here. As I pointed out previously, the main ingredients in Nugenix can be found in other supplements marketed to men over 40. Yes, Nugenix does have more Testofen (fenugreek) than other similar products. I like this, because there is a little encouraging evidence stemming from the use of this amount of Testofen. But, why can’t men just buy a bottle of fenugreek (or Testofen) and try that for a few weeks to see if it works, before buying the more expensive Nugenix?
No matter what you do, remember that the Nugenix website gives no published peer reviewed proof that Nugenix —itself—actually raises testosterone levels. So, if you are going to try Nugenix (or Testofen) I suggest you get your testosterone levels measured by your doctor before you start the supplement. Then, test the levels again in a month. You will know in a month if it worked or not. Measuring testosterone levels is the only true way to know if Nugenix is working.
What do you think?

MS stands for Mail Stop. Only certain places in the US use it in addresses. Exact same thing as a box #.
Joe, thanks for the feedback. I had a feeling it was something like that but wasn’t sure. Appreciate that!
supplement-geek.com is one of my favorite web sites of all time. You do fabulous work. All the research you do for us, complete strangers, is an invaluable service and I hope you really know how many people like myself have improved our lives (and saved a lot of time, effort and money) thanks to your knowledge and expertise on a subject that is of great importance to millions of people. Much respect and gratitude! Keep up the excellent work, my friend!
Hal, thanks VERY much! That’s the nicest thing I’ve heard in long time. I really appreciate you taking the time to write
Joe, thanks a bunch for your work on this. I have one minor thing to add, which is that I would never bother to check with BBB on anything. Wait, let me modify that. If you see problems reported to BBB,that’s useful, but a lack of reports can mean nothing. I followed up on a well known broker and BBB said “No complaints in recent years.” No wonder. He was in prison all that time, and it was commonly known in the community, so they had to be on Mars to be so ignorant.
Jim, thanks for your words and thats a good point about the BBB. I take a look at it and always try put a date next to when I checked it to give people an idea that things can change over time. That said the BBB is not perfects as you rightly said when it has no record. It’s just a step I go through as way to be as complete as I can.
They sent me a bottle after the trial bottle and charged my credit card. I called and asked for RMA. They gave me the RMA but the supervisor, Dennis, did not want to give me his last name. He said that is the way they operate.
Your article was outstanding! So little sober commentary and analysis is available for nutitional supplements. As a 60-year old male, I am almost halfway through an experiment that involves taking Nugenix for a month then stopping. I have not finished my first month and I think I feel better. Placebo? coincidence? I don’t know.
The second month (without Nugenix) will tell all for me. Not checking T-levels. Don’t care if they change. Feeling better and stronger and ‘ready for action’ are my goals and I am cautiously optimistic at this point. Damned shame about the price, though.
MichaelK, thanks I really appreciate that! For what its worth I hope it helps you and am glad you are feeling better. Much success!
Joe,
BD, As a 1st timer with this type of supplement I was really pleased with the way you took each segment of the advertising and product make-up and drilled down to the facts. Quite honestly, I’m stopping my subscription as there are way to many nebulous aspects to the product. I’m sticking with a vitamin supplement until something more tangible hits the market. My wallet thanks you for the research.
Barry, thanks for writing and I’m glad you found my review useful to you.
so after your research on this sounding bogus product,is there any product that you do suggest and we def appreciate your investigating this to this extent..Wayne
Thanks Wayne. Right now there isnt a product I have faith in because none of them have shown me they work through published peer reviewed research on their product. I addressed this also on my supplements questions page
Joe I enjoyed reading your evaluation of Nugenix thanks. Since this new product does not seem to offer proof that it does what it says, have you found any natural testosterone booster product that works?
Carlos, Im still looking… I like your website by the way
Joe,
I have read most of your reviews on male supplements that are supposed to boost testosterone. I do need to get my t-levels checked, but I’ve read of too many men that go to the trouble of getting their t-levels checked only to get a reply from their doctor that their “number” is in the average range, so that can’t get t-gel or similar products.
Also, for men that can get androgel/t-gel, etc, there is the concern that it can cause your body to stop producing the natural testosterone that it is already doing.
I am just looking for any way that I can try to boost the natural production of my own testosterone, if that is even possible.
I have used ED drugs with some success, and I don’t have a major ED issue as of yet, but at 43, I have found that I have definitely lost something from my youth in terms of stamina and maintaining “readiness”. I have worked on my diet and am working out 2-3 times a week, so about the only thing I have not been able to improve is my cardio fitness–which, if it would improve my circulation–might be at least something that will give me hope as I grow older and hope to maintain a decent sex life.
Do you have any general recommendations or thoughts since it appears that looking for a supplement to help improve our performance is not currently a viable option. What are the most important things I should do right now to at least try to maintain my current performance levels?
John, I would say try to work on cardio. it doesn’t even have to be intense cardio -just consistent moderate intensity cardio should help. That said I have experimented with fenugreek and 7 keto DHEA together just to see what would happen. Its not a slam dunk but I did notice some differences toward the end of the night oddly. I didn’t think it was significant but others may say differently.
When I suggest people get their testosterone levels measured first, I’m really just looking for a baseline reading. After they have that, they can try a product – Nugenix etc. for a month – and then retest the testosterone again. If the product worked, then T levels should go up.
Joe, thanks for the followup. I look forward to hearing your feedback on the Fenugreek and 7-Keto-DHEA combo. In the meantime, cardio, for improved circulation and general fitness is my best option, correct?
John, I took both fenugreek and 7 keto DHEA for 2 weeks and didn’t notice any significant differences from how I normally feel. I took exactly what the bottles said to take. I would say yes cardio has more benefits.
Thanks for all the legitimate information. You just saved me $69!
Rich, thanks glad to help.
Very informative, I like the way you broke down each ingredient. Keep up the good work.
Thanks Howard.
Hey Joe? It works! I am a 54 year male and a personal trainer for 30 years.. And I DO NOT work for nor am I affiliated with Nugenix in anyway other than buying their product as a consumer.
I first heard of Nugenix two months ago when I was offered a free sample while on a fitness website that I frequent.I figured that I would give it a try and see what the results are. After two months? It works.
I am a person that has a lot of stress in and around my life and my cortisol levels were through the roof and my testosterone was way down because of it. My muscles were breaking down even after working out they didn’t have the density and mass they once had. I was getting softer and softer by the month.
Of course my age and other variables played a major roll in the decline of the way my body was breaking down muscle fiber etc,however, after using this product for two months, I am convinced that it works! I have had an incredible turn around in my energy levels when at the gym and as far as libido? Well, the jury is still out on that one.. I am deciding if it has increased it or maintained it but I am sure that it works for rebuilding stamina and strength.
By the way, I do not believe that Nugenix works for me, ONLY because I want it to.. It has worked and I definitely believe that it has given me back what I lost and I will go on record saying so as I just did.
It may not work for everyone because of their own personal genetics and diet regiment, but there is no doubt in my mind if it works or not. As far as I concerned no further studies need to be conducted to convince me that it works.
TJ, thanks for your feedback. did you happen to have your testosterone or cortisol levels check before and after trying Nugenix?
Yes Sir and you are welcome! As of 8 months ago my testosterone was lower than 500 nanograms per deciliter and cortisol level was over 35.. as of three weeks ago my testosterone increased to 800 plus after I started taking Nugenix and cortisol is 18.1.
Just so everyone knows. I’m not here to dispute others opinions.. I am just giving mine and what I have personally experienced with this product. So if I am 1 out of 10 or 100.. It does work..Its not whether it works or not as much as it is the ratio of men that receive any benefit from it. So let me be the first one on your page to set the bar. After that? Well the rest will be either positive feedback or not.. Thank you Joe for getting back to me.
TJ, thank you for writing. I really do appreciate it
I am glad to have been able to add some feedback about this product.
You did, thanks
you sir, deserve a medal, for your well thought out responses to the advertisements, cutting through the BS and providing analysis to the average guy like me. many thanks. JD
John, you are very kind thanks. I’m the average guy also
I agree that why can’t men just buy some fenugreek… and take that for awhile instead of the perpetual 30 day mailings of a more expensive product. That kind of deal smells like a scam…
Hi Joe thanks for that important information you give to us and your valuable time that you put on this…….several months ago I was felling tired and no much energy….I went to doctor and I got blood tested and find out my testosterone level was very down…the doctor prescribed me androgel …..I used it for few months with no much result…….after I heard about the nugenix I called and I got the 18 days trial and I started to feel the difference ….although I like the product what I don’t like it’s the marketing way, and force us to buy every month ….so I called them and tried to cancel before the free trial and a very nice guy gave me another free trial that I accepted…..but now before my second trial finish I’ll will cancel because I can get it at gnc much cheaper…..for me really work but you. know everybody is different……… Thank you once again …
Jose, you are very welcome!
Thank you for your in-depth critique. Clearly, this product does not have the creds to be worth gambling one’s money on. Sites like yours are SO appreciated for exposing BS like this appears to be.
Brian, thanks I really appreciate your kind words.
Speak for yourself Brian because it does work and I have the proof that it does work.. I am surprised that Joe didn’t site my commentary on this thread.
TJ, I don’t remember seeing anything from you. its possible you went to spam if your comments contained any links. Thats the only thing I can think of. If you say it helped you then thats great but as Ive been told many times, we are all different and Im sure there will be others who have different results.
Joe you thanked me for my feedback.. Tj Bronson..
TJ, I always do
Reposted from 24 March 13- Yes Sir and you are welcome! As of 8 months ago my testosterone was lower than 500 nanograms per deciliter and cortisol level was over 35.. as of three weeks ago my testosterone increased to 800 plus after I started taking Nugenix and cortisol is 18.1.

TJ thanks for the update. Did you do anything different other than Nugenix? Any different exercise? Did you lose any weight?
I just got nugenix .should I try it or not? You have done alot of work and I appreciate it very very much!!!!
since you already got it, give it a shot if you like. I’d get your testosterone measured first if you want to be a little more scientific about it.
Guys, just go to your doctor and if you have low T levels you can be prescribed pure testosterone and at a fraction of these supplement prices. Androgel costs me $20/mo.
I took this supplement. I felt nothing, but i did have a constant smell of maple brown sugar in my nose. It was worse when i worked out.
Steve, wow, your the first to ever say that.
From Answers.com “The fruit of a plant originally from southeastern Europe and India. Fenugreek is part of the pea and clover family. The fruits are long and thin pods that harbor tiny seeds. Both the plant and the seeds emit a strong, spicy smell. The seeds have a sweet-and-sour flavor with an aftertaste of caramel and maple syrup that becomes stronger when the seeds are roasted. The food industry uses fenugreek to make an artificial flavor that imitates maple syrup.”
The supplement market is full of incredible claims with dubious research. I’ve spoken with a few industry people over the years and I learned that double blind studies along with actual monitoring free testosterone levels are nonexistent in every case.
But…
“Feelings” are a marketable commodity. Suggesting that someone should feel faster, bigger, smarter and so on is what they sell. Nobody wants to feel ripped off for spending fifty bucks on a bottle of voodoo squeezings so instead they feel better. Further, they tell others they feel better so they don’t feel foolish. See a patten here? Do you feel me?
I feel ya
Good analysis of the ads and published ingredients. I am a 67 year old guy who has been physically active my whole life. I work out 5 times a week and play tennis twice a week (doubles 2 hours). I started taking Nugenix about 4 months ago and noticed after about 2 months that my arms and legs were stronger and my reactions much, much quicker on the tennis court. I am convinced that the Nugenix was effective in these regards. There was also a modest increase in sexual performance.
Unfortunately, a Lifeline screening I underwent about a month ago revealed that I now suffer from a condition called Atrial Fibrilation. This seems to have been a condition with very recent onset. I can tell because I check my pulse fairly regularly, and it began creeping up about two month ago. My obvious concern is that the AFIB could be causally related to the ingestion of this product. Have you heard that any cardiac conditions may be caused by any of the ingredients of Nugenix? Thanks.
Norm, Ive never hear of any connection between Nugenix and atrial fibrillation or any other heart issue. Nugenix contains Tribulus and when I did my own little “experiment” of it, while I didn’t notice any improvements, when I stopped taking tribulus I did notice that my heart began skipping beats, something that never happened before. you can read my story on my post on tribulus here. My experiment was very nu-scientific but other than my experience Im not aware of any other heart-related issues.
Just a heads up, its possible your doctor may put you on blood thinners because of the Afib. if you are going to keep taking Nugenix, show him/her the ingredients in the product (and all other supplements you take too) because a lot of supplements are natural blood thinners. Your doctor needs to know this to balance the amount of blood thinner he/she gives you.
One word of caution related to the possibility of reduced blood pressure. L-Citrulline appears to act similar to L-Arginine in relaxing blood vessels. This has, as you reported, the side affect of lowering blood pressure, perhaps dangerously so. I had been taking an L-Arginine supplement for the purpose of improving blood flow and circulation. One morning I woke up and noticed a problem with the vision in my left eye. I went to see an optometrist and was diagnosed as having Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION) which is damage to the optic nerve. The damage is permanent, cannot be corrected with glasses, and there is no treatment.
I have lost roughly 50% of the visual field in my left eye as a result of this damage. The primary cause of NAION is restricted blood flow to the optic nerve. When blood pressure is lowered to an unsafe level the smaller blood vessels supplying the optic nerve collapse and blood flow is restricted. The problem mostly occurs while sleeping since blood pressure is naturally lower during sleep.
Combine the effects of supplements that also reduce blood pressure and you have increased the risk of NAION. I would suggest that anyone considering taking any supplements reported to lower blood pressure see an optometrist to determine if their optic disc is “crowded” or at risk.
I have now become very conscious of supplements or drugs with the potential for reducing blood pressure. I only have one eye left. Please be careful.
Lucien, oh I am so sorry that happened to you!!! You are right about L Citrulline. it can reduce blood pressure.
