Nutrakey | Iso Optima


ISO Optima™ is processed through cross flow micro-filtration (CFM) in a cold environment, to purify the protein and preserve the bioactive branch chain amino acids (BCAAs). Not all protein isolates are created equal. Some ‘isolates’ are treated through extreme heat and others are treated by acid, both of which degrade the quality of the protein by stripping it of essential BCAAs, which are intended to help the isolate absorb quickly into your muscles. ISO Optima™ is an incredibly pure and rapidly absorbing protein isolate that delivers 5.6 grams of bio-active branch chain amino acids.


Rapid Muscle Repair

Protein isolates are extremely fast absorbing, making them ideal proteins for post-workout recovery and essential for lean muscle growth. Few proteins can match the effectiveness of a 100% Whey Protein Isolate for post work out recovery.*

High in Protein, Not in Calories

ISO Optima™ contains no excess calories from unnecessary carbs, fillers, or flavorings. It’s easy to digest, low in carbs. Being free of fat, lactose, and sugar makes ISO Optima™ an excellent way to get adequate protein for lean muscle growth on a low-calorie diet.*


ISO Optima™ is sampled from gourmet white chocolate, savory vanilla cake, chocolate ice cream and other natural flavors. Taste test approved by athletes, our flavors are hand crafted to give you the unique flavor notes of your favorite binge snack, all while having ZERO sugars and GLUTEN FREE.

Very good taste

Better Taste Would Equal a Better Rating

I tried the Vanilla Cake Batter with water and with milk, the taste is just not all that for me. I do like that it is only 110 calories per scoop, and you get 25 g's of quality protein from that scoop. The overall supplement looks healthy for the most part, but I enjoy protein that has a good taste to it especially when I am eating cleaner to lose fat (kind of like a treat, but this just doesn't do it for me). I am considering trying the Whey version from Nutrakey and hopefully that will taste better!

Nutrakey Iso

Awesome taste, mix well. Good choice. Highly recommend.
