The Problem

You're Eating Well — But Your Gut Isn't Keeping Up

Most adults produce fewer digestive enzymes as they age, which means even the healthiest meals pass through your system partially undigested. Bloating, gas, sluggish energy after eating — these aren't just inconveniences. They're signs your gut isn't converting food into usable fuel.

  • check_circleCooked and processed foods destroy naturally occurring enzymes
  • check_circleUndigested food ferments in the gut — causing discomfort and inflammation

The Solution

MassZymes delivers a potent, high-protease blend of digestive enzymes that go to work the moment you swallow — breaking down proteins into amino acids, fats into fatty acids, and complex carbohydrates into fuel your cells can actually use. The result is less bloating, better energy, and more from every meal.

  • check_circleBreaks down all five macronutrient classes: proteins, fats, carbs, fiber, and sugars
  • check_circleHigh-protease formula prioritizes complete protein digestion
  • check_circleWorks with your body's natural digestive process — not against it

What's Inside MassZymes

A precisely calibrated enzyme stack targeting every stage of digestion — from the first bite to full cellular absorption.

science

Protease Blend (High Potency)

The cornerstone of MassZymes. A high-activity protease blend breaks peptide bonds in dietary proteins, converting them to free amino acids your muscles and tissues can absorb immediately. Critical for anyone on a high-protein diet.

nutrition

Amylase

Breaks down complex starches and carbohydrates into simple sugars your body can use for energy. Helps reduce the energy lag associated with heavy carbohydrate meals by improving absorption rate.

water_drop

Lipase

Cleaves triglycerides in dietary fats into glycerol and fatty acids. Supports absorption of fat-soluble vitamins (A, D, E, K) and omega-3s — nutrients that are largely wasted without adequate lipase activity.

eco

Cellulase

Humans don't naturally produce cellulase, so plant-based fibers typically pass through undigested. MassZymes adds this critical enzyme to unlock nutrients locked inside plant cell walls — making vegetables more bioavailable.

spa

Lactase

Breaks down lactose (milk sugar) into glucose and galactose. Allows people with lactose sensitivity to consume dairy without the bloating and cramping that typically follows.

biotech

Invertase & Alpha-Galactosidase

Targets sucrose and the complex sugars found in beans and cruciferous vegetables — notorious sources of fermentation-related gas. Provides relief for even the most sensitive digestive systems.

"After 20 years of studying sports nutrition and digestive health, I can tell you that enzyme sufficiency is the single most overlooked factor in recovery, body composition, and energy. MassZymes was formulated to solve that gap — and the results speak for themselves."

"Only a couple weeks in, but I can say my heartburn is basically gone. I've had horrible heartburn for so long — I tried everything. MassZymes was the thing that finally made the difference. I'm not exaggerating when I say this changed my daily life."

"Great product for breaking food down and getting things moving. I take 2 capsules with every meal and the difference in how I feel afterward is night and day. Less heaviness, less bloat, and I actually feel satisfied instead of stuffed."

"I eat a high-protein diet for training and used to feel completely wiped out after big meals. Since adding MassZymes my post-workout recovery meals digest cleanly — no crashes, no bloating. My coach noticed my energy levels too."

Finally Solved My Post-Meal Crashes

I'd been dealing with afternoon energy crashes for years and blamed stress and sleep. Turned out it was digestive inefficiency. Three weeks on MassZymes and I'm alert through the afternoon for the first time in years.

Bloating Gone After 10 Days

I was skeptical but desperate. Chronic bloating after every meal, didn't matter what I ate. By day 10 of MassZymes I noticed I was getting to the end of the day without that uncomfortable balloon feeling. By week three it was almost entirely gone.

— Kevin R., 38 — Portland, OR

Works Perfectly With Keto

High fat, moderate protein — digesting that properly is crucial. MassZymes handles the fat breakdown better than anything else I've tried. I'm absorbing my fat-soluble vitamins properly now and my labs confirm it. Worth every penny.

Your Questions About MassZymes, Answered

How many capsules should I take and when?add
Most users take 2–3 capsules with each meal, particularly larger or protein-rich meals. Taking them at the start of a meal allows the enzymes to begin working alongside your own digestive secretions. For very large meals, some users take an additional capsule mid-meal.
How quickly will I notice results?add
Many customers report reduced bloating and improved post-meal comfort within the first 1–2 weeks. For more chronic digestive issues, improvements typically build over 3–4 weeks as the gut environment improves. Energy and absorption benefits are often noticed within 2–3 weeks.
Is MassZymes suitable for vegetarians and vegans?add
Yes. MassZymes uses plant-derived and fermentation-derived enzymes. The capsule casing is vegetarian-friendly. It works effectively with plant-based, omnivore, keto, and high-protein diets.
Will taking supplemental enzymes make my body stop producing its own?add
No. Digestive enzymes are not hormones — supplementing them does not create a feedback loop that suppresses endogenous production. Your pancreas and salivary glands will continue producing enzymes at their normal rate. MassZymes simply augments what your body already makes.
What is the return policy?add
BiOptimizers offers a 365-day return policy. Unopened bottles qualify for a full refund minus shipping. For opened bottles, BiOptimizers provides a prorated refund based on how much product you've used. Contact their support team and they'll guide you through the process.
Can I take MassZymes with other BiOptimizers supplements?add
Yes — MassZymes is designed to be the digestive foundation of a supplement stack. It pairs naturally with P3-OM (proteolytic probiotics) for comprehensive gut support, and with Magnesium Breakthrough to support smooth muscle function in the digestive tract. Many BiOptimizers customers use all three together.
