Here’s something most people don’t think about: you can eat 200 grams of protein a day, but if your gut can’t break it down efficiently, a chunk of it goes to waste. That’s where MassZymes comes in. It’s a digestive enzyme supplement designed in particular around protein absorption.

BIOptimizers loaded this with protease, peptidase, and a blend of other enzymes that work across different pH levels in your digestive tract. The idea is simple, help your body actually use the protein you’re eating, not just pass it through.

Who Is This For?

Built for anyone eating high-protein diets, lifters, endurance athletes, CrossFitters, anyone pushing 1g+ per pound of bodyweight. If you deal with bloating after protein-heavy meals or feel like your recovery is slower than it should be, poor digestion might be the bottleneck.

Probably overkill if you eat moderate protein and have zero gut issues. And at about $65 a bottle, it’s not cheap. But for serious athletes who want every gram of protein to count, the math checks out.
