MassZymes 3.0 is the stronger pick for protein-focused athletes, but if general digestive discomfort — especially bloating after fat-heavy meals — is your problem, NOW Super Enzymes addresses root causes that MassZymes ignores entirely. This comparison answers a single practical question: which formula actually matches your digestive needs?
Both products solve real problems. They just solve different ones. Read this if you have been staring at two bottles and cannot figure out why they cost such different amounts or what that difference means for your gut.

BIOptimizers MassZymes 3.0
Best for: High-protein dieters, athletes, and anyone who bloats or feels heavy after protein-heavy meals
MassZymes 3.0 is built around protease — the enzyme class that breaks dietary protein into absorbable amino acids. The full stack includes Protease 4.5, Protease 6.0, Peptizyme SP (serrapeptase), Bromelain, Papain, Amylase, Lipase, Lactase, Alpha Galactosidase, and Hemicellulase. The formula also includes AstraZyme, a patented blend of astragalus and notoginseng extracts with ingredient-level human research showing improved amino acid absorption rates — a real differentiator from the dozens of enzyme blends that simply list ingredients without evidence.
Pricing:
- 250 capsules: $44.95 (83 servings at 3 caps each)
- 500 capsules: $79.95

At 3 capsules per meal taken once daily with your largest protein meal, a standard bottle lasts roughly two and a half months.
Onset timeline: Most users notice reduced post-meal protein bloating within 5 to 7 days. The alpha galactosidase content — which breaks down gas-producing oligosaccharides in beans and legumes — tends to show effect within the first two or three uses.
What works:
- Protease activity is meaningfully higher than most over-the-counter enzyme blends, with multiple protease strains targeting different protein structures
- AstraZyme is backed by ingredient-level absorption research, not just marketing language
- Full carbohydrate enzyme coverage (amylase, hemicellulase, alpha galactosidase) addresses multiple fermentation sources behind gas and bloating
- Lactase content helps whey users with mild lactose sensitivity
- Vegan-certified capsules with no animal-derived ingredients
What does not work:
- No Betaine HCl — if low stomach acid is your underlying problem, adding enzymes downstream does not fix it
- Lipase is included at 3,500 LU, but without ox bile or bile salt support, fat digestion coverage remains limited
- The 3-capsule serving size means 9 capsules per day if you take it with three meals — a real compliance issue for people already managing multiple supplements
Specific failure worth knowing: Taking MassZymes on an empty stomach is a genuine mistake. The high protease concentration causes noticeable burning and nausea when there is no food to buffer it. The label says “take with meals,” but that instruction does not feel urgent enough on the packaging — and the consequence of missing it is unpleasant enough to cost you at least one wasted serving and an uncomfortable hour.
Pros:
- Highest protease activity in this price range
- AstraZyme inclusion backed by ingredient-level absorption evidence
- Full carbohydrate enzyme stack including alpha galactosidase for legume-related gas
- Vegan-certified with no animal derivatives
- Lactase useful for dairy-sensitive whey users
Cons:
- No Betaine HCl — fails entirely if low stomach acid is the root cause
- Weak fat digestion support compared to ox-bile formulas
- High protease concentration causes GI distress if taken without food — the margin for error is real
- Cost per serving is higher than most broad-spectrum alternatives
NOW Super Enzymes
Best for: General digestive discomfort, fat malabsorption, post-gallbladder surgery support, and anyone starting with digestive enzyme supplementation
NOW Super Enzymes takes a fundamentally different approach. Rather than stacking high protease activity, it targets the full digestive process starting at the stomach. Each 2-capsule serving delivers Betaine HCl (650mg), Pancreatin 4X (200mg), Bromelain (150mg GDU), and Ox Bile Extract (100mg).
Pricing:
- 90 capsules: $18.99 (45 servings at 2 caps each)
- 180 capsules: ~$29.99
- Available at iHerb, Amazon, and most health food retailers without a subscription
The Betaine HCl angle: Low stomach acid is the most commonly overlooked driver of adult digestive problems — and it becomes more common after age 40, after prolonged PPI use, and under chronic stress. Adding enzymes downstream without addressing stomach acid deficiency often fails. NOW Super Enzymes addresses both layers simultaneously, which is why it outperforms many pricier enzyme-only products for general bloating complaints.
Onset timeline: Betaine HCl effects on post-meal heaviness and belching are often felt within the first three to five uses. If you experience heartburn after your first dose, the 650mg amount exceeds what your current acid levels require — a clear signal to start with half a serving and work up.
What works:
- Betaine HCl is the key differentiator — most enzyme blends skip stomach acid support entirely, addressing symptoms while ignoring the cause
- Ox Bile Extract supports fat emulsification, particularly valuable if you have had your gallbladder removed or eat a high-fat diet
- Pancreatin 4X covers protein, fat, and starch digestion in one ingredient
- 180-cap bottle keeps the monthly cost under $15
- Available everywhere without brand commitment or subscription
What does not work:
- Pancreatin 4X is listed in milligrams, not enzyme activity units — HUT, FIP, and GDU values are not disclosed, making it impossible to verify potency or compare meaningfully against products that do disclose these numbers
- Not suitable for vegans or vegetarians (ox bile is animal-derived)
- Protease activity is modest compared to dedicated formulas — not adequate if you eat 150g or more of protein daily
- The 650mg Betaine HCl dose can trigger heartburn in people who already have adequate or high stomach acid
Specific failure worth knowing: The missing enzyme activity data is a real transparency problem. When you buy Pancreatin 4X at 200mg, you do not know if you are getting low-grade or high-grade pancreatin — the “4X” designation refers to concentration relative to standard pancreatin, but base potency varies significantly by source. You are trusting the brand on a critical variable with no way to verify it. For a category where efficacy depends entirely on enzyme activity, that is an uncomfortable blind spot.
Pros:
- Betaine HCl addresses root-cause stomach acid issues, not just downstream symptoms
- Ox Bile Extract covers fat digestion — essential for patients post-cholecystectomy
- Lowest cost per serving at $0.42
- Available everywhere without subscription
- Pancreatin 4X covers multiple macronutrient pathways in one ingredient
Cons:
- Enzyme activity units (HUT/FIP) not disclosed — potency is unverifiable against competitors
- Not vegan or vegetarian-friendly
- Protease content is too modest for high-protein athletes
- 650mg Betaine HCl can cause heartburn if you already have normal stomach acid levels
The Verdict
MassZymes 3.0 wins for protein absorption. If you eat a high-protein diet, train hard, and notice post-meal heaviness or bloating after chicken, steak, or protein shakes, MassZymes addresses that directly. The AstraZyme inclusion is a genuine differentiator — not just added enzymes, but a studied mechanism for improving amino acid uptake. At $44.95 for 83 servings, you are paying for specificity, and it delivers on that promise.
NOW Super Enzymes wins for general digestive support, fat digestion, and value. If your symptoms are broader — bloating across meal types, fat intolerance, slow digestion, or you suspect low stomach acid — NOW covers ground that MassZymes does not touch. The Betaine HCl alone makes it a more complete digestive formula for most adults.
If you are over 40 and starting with digestive enzymes for the first time, begin with NOW Super Enzymes. Declining stomach acid is the most likely culprit, and no enzyme supplement can fix that from the downstream side alone.
If you have already tried broad-spectrum enzyme blends without results, MassZymes’ concentrated protease stack is worth trialing — particularly if protein is a large part of your diet and your previous enzyme product had undisclosed activity units.
If your gallbladder has been removed, NOW Super Enzymes is the clearer pick. The 100mg ox bile dose is conservative compared to clinical protocols, but it is a meaningful starting point for restoring fat digestion that MassZymes does not offer at all.
FAQ
Can I take MassZymes and NOW Super Enzymes together?
You can, but test each independently first. The combination adds Betaine HCl and ox bile from NOW to MassZymes’ high-protease stack — a more complete protocol than either alone. Give each product two to three weeks solo before combining, so you can actually tell what is working.
Does MassZymes help with bloating?
Yes, for carbohydrate and protein-driven bloating. The alpha galactosidase content specifically targets gas-producing oligosaccharides from beans, lentils, and vegetables — effects are usually noticeable within the first few uses. If your bloating comes primarily from fatty meals, MassZymes is less effective and NOW Super Enzymes with ox bile is the better fit.
Is NOW Super Enzymes safe after gallbladder removal?
Ox bile supplementation is commonly recommended post-cholecystectomy because bile is no longer stored and released in response to meals. NOW’s 100mg dose is on the low end of therapeutic protocols, which typically run 500mg or more, but it may relieve mild fat digestion symptoms. Confirm with your physician before starting.
Why does NOW Super Enzymes not list HUT or FIP values on the label?
NOW Foods discloses ingredient weights in milligrams, not standardized activity units. This is a labeling choice, not a legal requirement. It means you cannot directly compare potency against products that do disclose these values — and for a supplement where efficacy depends entirely on activity, not mass, it is a meaningful transparency gap.
Is the price difference between MassZymes and NOW actually justified?
For high-protein athletes: yes, MassZymes’ protease potency and AstraZyme are worth the premium if protein absorption is your specific problem. For general digestive support: no — you are paying for protease activity you may not need. The $26 gap per standard bottle buys you specificity, not universally better digestion.
