Key Features
Protein Breakdown
Loaded with tri-phase proteases that go after protein specifically, so more of what you eat turns into amino acids you can use.
Less Post-Meal Sluggishness
Takes some of the digestive load off so heavy meals don’t leave you wiped out the next hour.
Vegan Capsules
Plant-based capsules, no animal-derived fillers, no magnesium stearate.
Broad Spectrum Blend
Not just proteases. Also includes amylase, lipase and cellulase so carbs and fats get covered too.
Our Experience
We ran MassZymes through about three weeks of normal training with high-protein meals. Took 2-3 caps before the bigger meals, bumping to 4 on steak nights.
Where we noticed it most was the post-meal bloat, or really, the lack of it. Usually a big chicken-and-rice meal leaves us feeling heavy for an hour. That dropped noticeably. Recovery felt a touch faster too, though that one’s harder to prove.
If you don’t eat much protein or already digest well you won’t see dramatic changes. This product makes more sense for higher-protein eaters.
