Glycine
C₂H₅NO₂ / Amino acid
The simplest amino acid. Used in Dusk and Nightfall for the evening wind-down.
In the range
Why it is
in the range.
Glycine is the smallest of the amino acids and one of the most abundant in collagen. We use it in the two evening formulations.
Glycine is the main ingredient in Nightfall, at 3000 mg per sachet, and a supporting ingredient in Dusk at 1500 mg.
We use it because small studies have looked at glycine taken before bed alongside how people rate their sleep. Taking it earlier in the evening, in Dusk, is our own design choice.
Evidence
What the research shows
The research is encouraging but modest. Most trials are small and short, and the people in them were often already sleeping poorly.
Limits
What we do not claim
We do not claim that glycine treats any condition. If you have trouble sleeping most nights, speak to your GP.
Form
Which form we use
Pure glycine powder, with no added fillers.
