Precision Glycine

The dedicated sleep companion that supports the temperature drop your body uses to fall asleep.

Falling asleep is not just about feeling tired. One of the body’s key sleep-onset signals is a drop in core body temperature. When that shift happens smoothly, the transition into sleep usually does too.

Who it's for

For adults who want support with sleep onset, more settled nights, and clearer mornings without relying on a heavy or habit-forming nighttime routine.

The Story

Why this formula was built this way.

Glycine supports this by encouraging peripheral vasodilation, helping heat move out through the extremities so core temperature can fall more naturally. That makes it a useful match for people who feel wired at night, run warm, or have trouble settling into sleep.

Precision Glycine pairs with Precision Sleep to round out the protocol. The stack handles melatonin support and calming neurochemistry, while glycine adds a thermoregulation-based mechanism that helps complete the sleep picture.

The Evidence

Why this formula made the cut.

Educational summary. Not a substitute for personalised medical advice.

Study

Sleep onset via thermoregulation

Glycine supports peripheral vasodilation and heat dissipation, helping the body create the core-temperature drop that naturally precedes sleep onset.

Study

Sleep quality

Randomised controlled data using glycine-rich collagen peptides has shown fewer nighttime awakenings and improved subjective sleep quality, with polysomnography support in trial settings.

Study

Next-morning function

The same research also suggests better next-day cognitive performance and less fatigue, making glycine relevant not only for bedtime but for how you function the next morning.

Study

Tolerance profile

At the doses commonly used for sleep support, glycine is generally very well tolerated and works through thermoregulation rather than a strong sedative effect, which helps avoid a heavy hangover feeling.

Important Considerations

A few things to know before you start.

Medication interactions

1
  • Glycine has few notable interactions at this dose, but if you take clozapine or other medications affecting NMDA signalling, share it with your prescribing clinician before use.
