Sleep

Glycine

3 gper scoop

What it is

Glycine is an amino acid that acts as an inhibitory neurotransmitter. It also lowers core body temperature, which is one of the physiological triggers for falling asleep.

Why it is in ONCE DUSK

This is the ingredient most responsible for DUSK working on night one. Dropping core body temperature is part of how your body initiates sleep, and glycine does that directly.

Why this dose

Three grams is the dose used in the sleep research. Smaller amounts appear in plenty of products as a sweetener or a chelation partner, but 3 g is the amount studied for sleep.

The form we specify

Minimum 98% purity.

How it works with the rest of the formula

Glycine does double duty here. It is the fastest-acting sleep ingredient in the formula, and it is also one of the three amino acids the body uses to make creatine, which DUSK carries separately. The magnesium adds a little more glycine again, because bisglycinate is magnesium bonded to it.

What to look for on any label

Glycine is cheap, which is why you often see it on labels at amounts far below the 3 g used in the sleep research, sometimes as a sweetener or a chelation partner rather than as an active. Check the actual number. Purity should be at least 98%, and it should be listed as its own line rather than hidden inside a proprietary blend.

The honest limit

Glycine helps you fall asleep faster and improves how rested you feel. It is not a sedative and it will not knock you out.

Questions

How much glycine do you need for sleep?

Three grams is the dose used in the sleep research, and it is what DUSK carries.

Does glycine work the first night?

Sleep is the fastest thing most people notice with DUSK, and glycine is the main reason. Skin and hair work on much longer timelines.

Is glycine a sedative?

No. It lowers core body temperature and acts as an inhibitory neurotransmitter, which supports falling asleep naturally rather than forcing unconsciousness.
