About Multi-Enzyme Complex (amylase, protease, lipase, lactase, cellulase)
Generic entry for proprietary multi-enzyme complexes (typically fungal amylase, protease, lipase, lactase, cellulase; sometimes bromelain/papain/alpha-galactosidase). Individual enzymes with their own evidence base (lactase, bromelain, papain, alpha-galactosidase, pepsin) have separate entries — this entry catches undivided blend rows such as DigeZyme or 'digestive enzyme blend'. Human evidence for OTC blends in otherwise healthy people is thin and largely manufacturer-run: a 60-day randomized double-blind placebo-controlled trial of DigeZyme in functional dyspepsia (Majeed 2018) reported symptom-score improvements; small crossover trials report reduced post-exercise muscle soreness with DigeZyme; broader reviews (e.g. Ianiro 2016) find supportive data only for specific enzymes and conditions (lactase for lactose intolerance, alpha-galactosidase for gas, pancreatic enzymes for exocrine pancreatic insufficiency). Blends added to protein powders and mass gainers at 20–100 mg are marketing-scale doses with no outcome data. Generally safe; fungal-derived enzymes may trigger allergy in sensitive people.
What Multi-Enzyme Complex (amylase, protease, lipase, lactase, cellulase) supports
- May ease functional dyspepsia symptoms (one manufacturer RCT)
- Lactase component helps digest lactose
How much Multi-Enzyme Complex (amylase, protease, lipase, lactase, cellulase) to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
50–500
mg
Blend weights on labels (50–500 mg) are a weak proxy: enzyme potency is set by activity units (DU amylase, HUT protease, FIP lipase, ALU lactase), which most blend labels omit. DigeZyme (Sabinsa) is standardized at ~50 mg per dose; branded blends in protein powders at 20–100 mg are typical. Prescription pancreatic enzyme replacement is dosed in tens of thousands of lipase units and is a different product class.
Clinical evidence
Limited clinical evidence. One 60-day RCT (DigeZyme, functional dyspepsia) plus small soreness crossovers, all manufacturer-run; label mg does not reflect enzyme activity
