Researched for: oral glycine sleep research
Also known as: Aminoacetic acid
Glycine is the smallest amino acid, serving as both an inhibitory neurotransmitter (glycine receptors in the spinal cord/brainstem) and a major structural component of collagen. It has been studied for sleep-quality outcomes and as a component of numerous metabolic pathways (glutathione, creatine, and purine synthesis).
Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.
Data source: Small controlled human sleep study
Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.
Amounts and schedules are separated by administration route. Evidence badges distinguish labels, human studies, preclinical work, community reports, and evidence gaps.
3 g before bedtime
Context: PMID 22529837
Formulation: Oral-mucosal formulations are not dose-equivalent to injectable or topical formulations.
Route safety: Research-study protocol only; it is not an approved or individualized instruction and should not be extrapolated to another route.
No route-specific amount established in the reviewed record.
Context: The catalog identifies this route, but its reviewed sources do not establish a separate amount and schedule for it.
Route safety: Non-human or laboratory exposure. It cannot be converted into a human dose.
Do not convert an amount between routes. Bioavailability, formulation, sterility, monitoring, and clinical context differ by route. Research-use context only; independently verify every cited source.
Reflects patterns reported in research/community literature only. Not a safety guarantee, medical advice, or interaction warning for human use.
The prior 10-15 g collagen or methylation entry lacked a cited protocol and was removed. The 3 g sleep evidence comes from small Japanese studies and should not be generalized to treatment of insomnia.
Supplementary research context only. Not medical advice or a treatment recommendation.
