Interaction guide

Glycine and sedative context

Glycine is often placed in sleep stacks, which makes alcohol, sedating medications, antihistamines, melatonin, and calming botanicals part of the practical safety review.

Default spacing rule

Do not evaluate glycine in a crowded sleep stack. Keep the evening routine stable, avoid alcohol or sedative stacking unless a clinician clears it, and watch next-day alertness.
