Does glycine actually improve sleep?

Glycine, a simple amino acid taken before bed, is a quieter sleep contender — small studies link it to faster sleep onset and better next‑day alertness.

1–10 SUBJECTIVE RATINGONE VARIABLENULLS REPORTED

THE COMPARISON — ONE VARIABLE CHANGES

A · GLYCINEThe nights with glycine. Everything else in your routine stays exactly as it normally is — one variable is what makes the difference readable.

B · BASELINEYour normal nights, nothing changed. These are the control your glycine nights are measured against.

Everything else stays as normal — one variable is what makes the difference readable.

WHAT THE RESEARCH SAYSA few small trials found ~3g glycine before bed improved subjective sleep quality and reduced daytime fatigue, possibly by gently lowering core body temperature.The research base is small, so it's a strong self‑test candidate — cheap, well‑tolerated, and easy to compare against your normal nights.

01Rate one thing. Each morning: your sleep, 1–10. Five seconds. Subjective on purpose — it's your outcome, not a wearable's.

02Context rides along. Sleep duration and screen time from Apple Health / Health Connect add context if you connect them. Optional, never required.

03A verdict that admits uncertainty. Likely helped · no clear difference · likely made it worse — with how confident, not just which. Too few clean days? The app says so instead of rounding up.
