glycine dosage before bed
Glycine before bed may support better sleep by lowering core body temperature, calming neural activity, and promoting more efficient slow-wave sleep. Research on glycine for sleep most commonly uses a glycine dosage before bed of 3 grams, taken about 30 minutes before bedtime, with benefits including faster sleep onset, improved sleep efficiency, and less next-day fatigue. Glycine is not a sedative and may work best for people with poor sleep quality or unrefreshing sleep.
