Isagenix is a MLM (Multi-Level Marketing) company just like Beachbody (who sells Shakeology) and Herbalife.
This means the way they sell stuff is to hire independent reps that sell their products for them.
The reason I bring this up is not to knock on MLM companies (there are plenty of good ones out there) but to point out that most Isagenix reviews you see online are from reviewers that have a vested interest in selling Isagenix products.
While I do sell a plant protein powder of my own, my review of Isagenix protein powders are as unbiased as possible. I evaluated their products based on two objective criteria: 1.) Ingredients and 2.) Nutrition.
Here’s what my analysis revealed …

Isagenix Reviews: Methodology
Similar to my other plant-based protein powder reviews, I am analyzing Isagenix protein powders based on health and nutrition … NOT taste. If you want to read reviews about how it tastes, check their website and Amazon.
Let’s get started …
Isagenix sells three types of protein powder:
IsaPro (90 calories, 1 gram of sugar, and 18 grams of protein per serving)
IsaLean Shake (240 calories, 6-7 grams of sugar, and 24 grams of protein per serving)
IsaLean Pro Shake (280 calories, 9 grams of sugar, and 36 grams of protein per serving)
IsaPro is marketed toward people trying to lose weight. The latter two target more active people who are looking for more calories and protein per serving.
Next, let’s review what’s in them.
Here are complete nutrition facts information labels and ingredient list analyses for each product and flavor …
Sugar: Sugar is one of the most common ingredients in Isagenix shakes. While IsaPro and IsaLean Plant Based only have 1 gram of sugar, IsaLean Shake and IsaLean Pro Shakes have 9 and 11 grams of sugar, respectively (from fructose). That’s just way too much added sugar for a protein shake–over 1/3 of the recommended daily intake for women!
Natural flavors: Like most flavored protein powders, Isagenix uses “natural” flavors. Despite their innocent-sounding name, the Center for Science in the Public Interest (CSPI) says natural flavors “may trigger an acute, allergic reaction, intolerance, or other problems.” I personally avoid products that have them, because you really have no idea what’s in them (and food companies aren’t required to tell you).
Gums/Thickeners: Isagenix uses several different types of gums, some of which may be disruptive to gut health. For example, xanthan gum may lead to GI bloating, gas, and diarrhea.
Organic: Isagenix’s products are not organic, which means their ingredients could be exposed to chemical pesticides and herbicides.
Cost: At $.07-.08/gram, Isagenix is expensive compared to similar powders. (Note: I use cost per gram to account for different serving sizes).
Bottom Line: Are Isagenix IsaLean and IsaPro Protein Shakes and Powders Good for You?
In my personal opinion, the only Isagenix shakes I recommend are the Plant Based Whole Blend IsaLean Shake because they’re low in sugar (1 gram) and have a solid blend of vitamins, minerals, fiber, and probiotics.
All other Isagenix protein products I reviewed contain added sugar, gums, and flavors, which I do not recommend.
There are definitely worse protein powders you can buy, but based on my reviews of all Isagenix products and ingredient / nutrition analysis, I recommend sticking with a product with 100% real food, organic ingredients instead.
