Isagenix IsaLean vs. Unicity Complete: Protein Shake Comparison

diabetes type 2 insulin resistance intermittent fasting protein shakes unicity complete weight loss Nov 19, 2021

Protein is critical in building and maintaining healthy muscle and bone. Most people do not get enough 'digestible forms' of protein as part of a healthy dietary intake. In addition to having little to no insulin response, adequate protein consumption also helps people feel fuller longer and reduces the tendency to over eat.

In this article we will take a look at the Isagenix IsaLean as a comparison to the Unicity Complete protein shake powders. Protein is foundational to managing our weight and body composition as well as enhance muscle growth, immune function and exercise recovery. Protein shake powders are helpful and convenient when used as part of a healthy program, like the Feel Great System

Many Varieties of Protein Shakes

First, lets get some clarity on the different kinds of protein powders that are found on the market. One is the “muscle/fitness” formulation and the other is the “meal replacement protein shake” formulation. Each of these needs to have certain ingredients and specific characteristic in their formulation to make them of value for their intended purpose.  To learn more about how to select a protein, visit my previous article titled How to Choose the Best Protein Powder.

This is where the knowledge and information breakdown begins at the consumer level and through mass marketing. As consumers, we are quick to only look at the “Grams of protein per serving” without really understanding what we are purchasing and why.

A high quality premium meal replacement must provide an ideal macronutrient ratio of healthy fat and muscle-building protein, while avoiding insulin-spiking carbohydrates. 

Sources of Protein in these Shakes

There are two main sources of protein powders (non-vegan) being Whey Protein Concentrate and Whey Protein Isolate. Whey Isolate has a higher bio-availability meaning the body will absorb more of it at a faster rate with little digestion. This is measured in the scientific world as an amino acid score (PDCAAS).

The Benchmark to Evaluate Meal Replacement Protein Shakes

When the creators of the GetFit21 program set out to find THE BEST protein meal replacement formulation they set the benchmark on 2 criteria that would make up a healthy well-rounded meal replacement.

  1. Macro Score: Protein (g) + Fiber (g) – Carbs (g)
  2. Nutrient Score: # of vitamins and minerals at 100% of daily value.

Isagenx IsaLean breakdown is as follows:

  • 23g Protein
  • 4g Fiber
  • 27g Carbs (16g from Sugar) a 23g NET carb load

Unicity Complete breakdown is as follows:

  • 20g Protein
  • 5g Fiber
  • 13g Carbs (5g from Sugar – source being organic sugar cane) an 8g NET carb load

Based on this criteria, the Isagenix falls into the lower left corner "Why Am I Using This? (nutrient poor, protein poor)" while the Unicity Complete falls into the upper right corner of the chart "Quality Protein Meal Replacement (nutrient rich, protein rich)".

Isagenix IsaLean Protein Source

The main protein source in Isagenix is an “Exclusive IsaPro™ Complex” which is made up of Whey Concentrate, calcium caseinate (casein in milk) and nonfat dry milk. 23g of protein per serving (2 scoops). The remaining product ingredient list is quite lengthy, and we won’t go into that here.

Unicity Complete Protein Source

Unicity Complete is a blend of a Whey concentrate and Whey Isolate comprising of an amino acid score of 135, that’s based on independent research. It is not known what the Isagenix amino acid score. Most companies do not publish this information.

If you look closer to the Unicity Complete Nutrition Facts you will see the “Typical Amino Acid Per Serving” profile chart. This is the essential and non-essential amino acids that comprise the 20g of protein per serving that makes up the 135 on the amino acid score (PDCAAS). This is critical information when comparing grams of protein from product-to-product.

Carb Load Comparison

You will see a big difference in the NET carb load between the two products. Keep in mind that 4g of sugar = 1 teaspoon. Isagenic IsaLean has 22g of Carbs (8g of Fiber) for a 15g of net carbs which is the same as 3-3/4 teaspoons of sugar for breakfast. That’s an alarming amount of sugar at 7 grams. Unicity Complete has 9g of Carbs (7g of Fiber) for a 2g of net carbs. This will have a very negligible impact on your blood sugars. 

Cost Per Serving

A 14 serving canister of Isagenix IsaLean retails for $53.27 US. So if you were to do 1 shake a day for a total of 28 days’ worth, the price would be $106.54 US. Cost per serving $3.80 US.
With Complete, a 30 day supply retails for $89 US ($60 US for Wholesale Member price). Cost per serving $2.96 US ($2.00 US wholesale member price).

Vitamin and Minerals

Lastly, in reviewing the Vitamins/Minerals profile from a % of daily allowance for Isagenix it does not match up to Unicity Complete for the essential nutrients.
