Body composition evidence brief
Digestive enzyme supplements provide enzymes such as proteases, lactase, amylase, or lipase. Claims usually center on digestion, bloating, protein absorption, and nutrient uptake.
Some protease studies show amino-acid absorption or soreness-marker signals, but direct strength, hypertrophy, or recovery outcomes remain weak.
Small RCTs show absorption or soreness-marker signals; reviews do not establish strength or hypertrophy outcomes.
Effects are enzyme- and protein-specific; protease blends, lactase, broad digestive enzymes, and probiotic blends are different products.
Most relevant for a clearly defined digestive-tolerance problem, not for promising more muscle from the same protein.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
