According to the Isagenix website, IsaLean Shakes “contain superior nutrition compared to other meal replacement shakes on the market” and are designed to “take your health and performance to new levels.” Powerful words indeed; but words aside, the big question is, does the Isagenix shake work or not? In this review, I’m going to look at the clinical research and ingredients in the IsaLean Shake. Hopefully this will help you better decide if the IsaLean Shake is right for you.
IsaLean Shake Ingredients
According to the product website, one Isagenix IsaLean Shake (Dutch chocolate flavor) has 240 calories per packet and the following nutritional information:
|Calories from fat = 55|
|Calories from saturated fat = 20|
|Total Fat 6 g||9%|
|Saturated fat 2 g||10%|
|Trans fat 0g|
|Polyunsaturated fat 0.5g|
|Monounsaturated fat 3g|
|Sodium 265 mg||11%|
|Potassium 430 mg||12%|
|Total carbohydrate 24g||8%|
|Dietary fiber 8g||32%|
DV = daily value. DV based on eating 2000 calories per day
Tip. The easy way to read a food label in the US is to remember these two facts about the daily values (DV):
- When you see 5% or less, it’s low in that nutrient.
- When you see 20% or more, it’s high in that nutrient.
Looking at the basic nutrition label for the product, we can say that the Isagenix Lean Shake is high in protein. Its 24 grams of protein provides 48% of the body’s protein need per day (assuming you are eating 2,000 calories per day).tell them to cut their calories and see who lost the most weight and was the healthiest?
Another study option could be to compare the weight loss and health benefits of the IsaLean Shake to other meal popular replacement shakes such as:
- Shakeology (click to see my review)
- Body by Vi Shakes (click to see my review)
- Right Size Smoothies (click to see my review)
- Herbalife Formula 1 Shakes (click to see my review)
Heck, they could have even compared the IsaLean Shake to Slimfast!
Study #2. The other study I located was titled Intermittent fasting combined with calorie restriction is effective for weight loss and cardio-protection in obese women. This study was published in Nutrition Journal.
Here’s the thing. This is the SAME study as study #1. As such, it suffers from the same drawbacks that I’ve already covered. Why did they re-purpose the same study data under a different name?
Bottom line: Whether it’s kosher or not in the scientific community to do re-purpose the same data under a different name is irrelevant in my opinion. It’s sneaky science and it gives Isagenix distributors a false sense of how much research supports the products they sell.

IsaLean Shake and Exercise
The Isagenix website notes that the IsaLean shake is designed to “take your health and performance to new levels.” By “performance” I assume they are referring to exercise performance. While I don’t think the IsaLean Shake will hurt the ability to exercise, I am also not aware of any published peer-reviewed research to show it improves exercise ability either. It might or might not. There appears to be no good proof either way.
It would be interesting to compare the IsaLean Shake to anther brand, such as the Herbalife Formula 1 shake, to see which might make people bigger, stronger, faster, or healthier.
The Isagenix Cleanse
Included in the Isagenix program are cleanse days on which people eat fewer calories in conjunction with taking various Isagenix supplements. This is said to rid the body of toxins, which, after they are lost, makes it easier to burn fat and lose weight. But what are these toxins? I don’t know. I’m also not aware of any peer-reviewed evidence of toxins being released during the cleansing process.
The Isagenix Company
Isagenix―also called Isagenix International LLC―was founded by Dr. John Anderson and Jim and Kathy Coover in 2002. Dr. John Anderson is called the “Master Formulator” of several Isagenix supplements.
According to the product website, the company is located at 2225 S. Price Road, Chandler, Arizona 85286. That address doesn’t come up on Google maps, but I did locate another address for “Isagenix International.” That address is 601 S 54th St, Chandler, AZ and on Google maps, does indeed show a building that says “Isagenix” on the outside. That’s good.
Isagenix has a contact number of: 480-889-5747. According to the Better Business Bureau file on Isagenix, the company also has a contact number of 480-889-5777. The BBB gives the company a rating of “A+” as of 1/9/15. See the BBB file for updates and more information.
Isagenix Side Effects
I Googled “Isagenix IsaLean Shake side effects” and did not see much in the way of people saying bad things about it, but I must also say that most of the search results I saw appear to be dominated by pro-Isagenix websites. Looking at the ingredients, I think if you are healthy, then the IsaLean Shake is probably safe. For those who have health problems, show the ingredients to your doctor or pharmacist, just to be safe.
Does It Work?
There are a few things I like about the Isagenix IsaLean Shake. First, I like that it has 240 calories. While this is a bit more calories than in other shakes—like Shakeology—I think this is probably closer to what people typically eat for a snack. I also like that the IsaLean Shake has more fiber. In addition, I like that the shake has 24g of protein, which when combined with the fiber, might help people feel full longer, reducing overeating setbacks. While not proven, the added protein might also help spare muscle loss during dieting.
The big question, however, is this: Is the Isagenix IsaLean Shake best for weight loss? While there is some research on the product, I see no compelling proof that it’s better than other shakes. While I feel it can be a healthy addition to the diet, I see no benefits―other than convenience―that it’s healthier than the homemade shake I make in my kitchen. I think this is an important point to remember for those who are price-sensitive, because the shakes can be expensive. I do believe that if people follow the Isagenix program, they will lose weight. But that’s not because of anything unique in the IsaLean Shake or the cleanse system. I believe people lose weight with Isagenix because they eat fewer calories.
