The score explained

Why 7.2 of 10: Provisional: plausible and safe, but the human trial base is thin.

what’s good

  • Very cheap per night
  • Well tolerated, no morning grogginess
worth knowing
  • Trials are small and short
  • Typical study dose is 3g, three capsules

what the evidence says

Glycine has a handful of small human trials suggesting it helps people fall asleep a little faster and feel more refreshed the next day, likely via a mild drop in core body temperature. The trials are short, small and mostly from one research group, so the effect is plausible but not firmly established. It is safe and cheap, which makes it a reasonable low-risk experiment rather than a proven fix.

Plain-language assessment of the human evidence. No cherry-picked citations.
