Deep Sleep Duo

Glycine + Magnesium

Glycine lowers core body temperature, a critical trigger for sleep onset and slow-wave sleep. Magnesium activates GABA receptors and suppresses the stress hormone system. Two completely different sleep mechanisms working together.

This pair requires two separate supplements. Both are needed for the synergy to work.

Glycine

Glycine acts as an inhibitory neurotransmitter and uniquely lowers core body temperature by dilating peripheral blood vessels. 3 g is the clinically validated dose. Can be taken as powder mixed in water.

Magnesium Glycinate

Magnesium glycinate activates GABA-A receptors and inhibits NMDA excitability to reduce arousal. The glycinate form delivers additional glycine, creating a natural stacking effect with the pair.

How to take this pair: Take 3 g glycine 30 minutes before bed on an empty stomach or with water. Take 300-400 mg magnesium glycinate 30-60 minutes before bed with a small snack if GI-sensitive. Avoid magnesium oxide (poor absorption, causes loose stools); use glycinate or malate forms. Glycine improvements typically appear within 2-3 nights. Magnesium benefits accumulate over 1-2 weeks.
