Headline Finding

Crossover RCT: lactase tablets reduced symptoms and cut 180-minute breath hydrogen by about 55% versus placebo in confirmed lactose intolerance.

Dose Context

Use with the lactose-containing food; dose depends on product enzyme units, lactose load, and individual tolerance.

Important Caveat

Lactose intolerance is not a milk allergy. Persistent, severe, or unexplained digestive symptoms should be assessed rather than self-managed indefinitely.

How To Read This Rating

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.
