Isagenix Protein Powder Reviews and Nutrition/Ingredients Analysis

isagenix protein powder products review 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 “reps” that push Isagenix products on family and friends.

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 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 three objective criteria: 1.) Ingredients, 2.) Nutrition, and 3.) Cost.

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.

So here’s how this works:

First I’ll show the nutrition facts labels and ingredients for each Isagenix Protein Powder. Then I’ll show you my “red flags” for each.

Let’s get started …

Isagenix sells three types of protein powder:

  1. IsaPro (90 calories and 18 grams of protein per serving)
  2. IsaLean Shake (240 calories and 24 grams of protein per serving)
  3. IsaLean Pro Shake (280 calories 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 …

Lots of red flags here! Here’s why I flagged each:

  1. Protein sources: Most of Isagenix’s products contain whey protein concentrate or milk protein. Dairy-based protein powders has been shown to have negative side effects for many people. If you have a sensitive gut, you may want to avoid whey because of its inflammatory properties.
  2. Sugar: Sugar is one of the most common ingredients in Isagenix shakes. While IsaPro only has 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!
  3. 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).
  4. Gums/Thickeners: Isagenix uses a lot of different additives and gums, some of which may be disruptive to gut health. For example, xanthan gum may lead to GI bloating, gas, and diarrhea.
  5. Organic: Isagenix’s products are not organic, which means most of their ingredients may be sprayed with chemical pesticides and herbicides.
  6. 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 Protein Shakes and Powders Good for You?

Isagenix says this on its website:

IsaLean Shake contains superior nutrition compared to other meal replacement shakes on the market. They contain exclusively sourced Myo-IsaLean Complex™, and the highest-quality whey protein from pasture-raised cows that are not treated with hormones or routine antibiotics.

“Superior nutrition” is quite the overstatement.

My Isagenix review can be summed up as-follows:

Isagenix shakes:

1.) Are not organic.

2.) Contain added sugar.

3.) Contain hidden junk ingredients and additives, fillers, and flavors.

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.
