ISO-Z5® was developed with a precise ratio of protein sources and a digestive enzyme complex for optimal absorption. It combines two key isolate sources – whey and milk – so you get the diversity of a blend with the purity of an isolate.*

  • 30g High-Quality Isolate Protein Per Serving*
  • Supports Absorption of Amino Acids to Build Muscle Protein*
  • Features ProHydrolase® for 133x Faster Digestion Than the Leading Competitor*

ISO-Z5® features ProHydrolase®, which supports rapid and complete digestion of proteins into di and tri peptides, allowing for maximum muscle synthesis. ProHydrolase® is a novel enzyme complex that digests 133x faster than the leading competitor. ISO-Z5® provides your body a source of high-quality protein for maximum muscle building, repair and recovery.

Naturally occurring enzymes in the body break down proteins into small peptides so they can be absorbed into the body. However, if ingested protein is not successfully broken down within 90 minutes, there is a risk of the protein being lost because it has missed the normal absorption time frame. The ProHydrolase® enzyme in ISO-Z5® eliminates this risk. It rapidly breaks down more than 90% of protein within 30 minutes, ensuring that the maximum amount of bio-usable peptides are available for absorption.

SUGGESTED USE: Add 2 scoops to 6-8 oz. of cold water or milk. For more thickness, blend with ice cubes or adjust mixing amounts to taste. Drink within 60 minutes of mixing for optimal taste.

WARNING: If you are pregnant, nursing or taking medications, consult your physician before use. Do not use if tamper-resistant seal is broken.

Great Lean Results, Great Green Poop!

I've been using this product 2-3 times a day in order to have extra calories, and get proper protein input. As a college student, I cycle with cheaper proteins and once every few months I buy a real expensive, name-brand product. During ISO-Z5, I have seen added lean muscles to my arms and back. I have thoroughly enjoyed the blue-berry taste... Best with milk! I've used it for about 3 weeks and have thus far added 5lbs, thats with an 2400 calories/day. On the negative, the Blue Dye #1 will turn your poop green. I mean here and there i'll have green stool, but when it happens for 3 days straight you begin to worry. after much research, Blue dyes are notorious for creating green stool. So be aware of what may happen if you drink protein in this high quantity!! Still a great product, I don't expect a disclaimer on the bucket... but that's why I'm here to review.
It's okay

For the most part I like the content, and I like that it's a protein iso. However, I did not realize it contained artificial sweeteners until after I bought it. The taste of artificial sweeteners ruins it, let alone the harm that they cause to the body. It's a shame it's so hard to find good proteins, or any workout supplements for that matter, that don't have any fake ingredients. For as much as this stuff is I'd hope for all real ingredients. I should have paid better attention. After this container is gone I'll be switching back to a former brand that sells natural protein. And your websites captcha's are ridiculous.
