ISO-ology: 100% Leucine-Enhanced Whey Isolate

5g Active Leucine Trigger

High Protein: 30g per Serving

Very Low Carbs, Sugar & Fat


Made with Premium Grass-Fed Dairy

ISO-ology is specifically engineered to optimize your Post Workout (PWO) nutrition protocol by triggering the maximum anabolic response possible from a whey protein supplement. In fact, gram for gram & scoop for scoop, ISO-ology has up to 100% more Leucine, the most important muscle-building amino acid, compared to any other protein available

Because ISO-ology is 100% Pure Whey Isolate it is essentially lactose & carbohydrate-free and is ideal for people with lactose-sensitivity and those following carb-restricted diets.

2x Leucine Compared to Regular Whey

Leucine is considered the “muscle-building amino” because of its important roles in: 1) Stimulating muscle protein synthesis, 2) Acting as a nitrogen donor to help build new muscle, and 3) Producing an insulinogenic response that promotes amino acid absorption.
You probably know that there’s a 40-55 minute “window of opportunity” following a good workout to consume the proper nutrition in order to optimize recovery and to build new muscle. Leading research suggests that during this time frame it is best to consume a complete protein that contains about 4g or more of Leucine.1
Most whey protein unfortunately contains 2g Leucine per scoop. ISO-ology on the other hand provides a total of 5g Leucine per scoop. Research shows that this increased dosage of Leucine may amplify new muscle protein synthesis by two-fold or even more by signaling the body’s processes of new muscle growth.2,3

Leucine Visibility Test

Can you visually see the added Leucine & BCAAs in your protein? Free-form amino acids appear as shiny specks that are highly visible, especially in all darker-colored and chocolate-flavored proteins. Simply put, if you cannot see the additional amino acids, they are not there! This means you’re getting only a minimal amount of the added Leucine/BCAAs and not enough to have a significant muscle-building effect.
Note that Body Nutrition has chosen to enhance its ISO-ology with free-form Leucine but without additional Isoleucine and Valine. We based this decision on the fact that the naturally-occurring levels of these other two BCAAs whey are already present in whey at ample quantities for the desired anabolic response.

Real Customers, Real Reviews

Body Nutrition really hit this one out of the park. There is absolutely nothing I would change about this. It doesn’t taste like chocolate with hints of peanut butter, it doesn’t taste like peanut butter with hints of chocolate – it tastes like a Reese’s Cup. Plain and simple. The level of chocolate and levels of PB are spot on and taste excellent.

Taste: 5/5 This is the best tasting 100% whey protein I’ve ever had. Prior to tasting this protein, my favorite was Gold Standard Mocha Cappuccino, which I gave a rating of 5/5. ISO-ology Jamocha tastes slightly (but noticeable enough) better, so I am really impressed. There was no after taste of artificial sweetener.
