Vit D plays a role in most of your body’s systems, so think of it as a non-negotiable requirement for good health. Vit D 3 supplement type and dosage must be based on yourvserum levels and personal genetic pathway for Vit D activation, transport and binding.

Let me know if taking glycine before bed enhances your sleep for you.

Glycine works for sleep but doesn't work like a typical "sleep supplement." It works like a thermostat.

When you take 3g of glycine before bed, it crosses the blood-brain barrier and binds to NMDA receptors in the suprachiasmatic nucleus, the brain's master circadian clock. This activates the medial preoptic area, which triggers peripheral vasodilation: blood flow increases to your hands and feet, heat radiates out through the skin, and your core body temperature drops. That temperature drop is the same signal your body produces naturally before sleep onset. Glycine just makes it happen more reliably.

This was mapped at Stanford by Kawai and colleagues. When they ablated the SCN in animal models, glycine's sleep-promoting and hypothermic effects disappeared entirely, confirming this is the target, not a downstream side effect. In human trials, 3g before bed reduced sleep-onset latency and next-day fatigue in volunteers with sleep complaints.

Polysomnographic data showed improved subjective sleep quality correlated with the temperature shift. The practical detail nobody mentions: glycine is one of the cheapest amino acids on the market. A 3g dose costs roughly nine cents. It has no sedative hangover because it isn't a sedative. It works through the same thermoregulatory cascade that a hot bath before bed exploits, peripheral vasodilation leading to core cooling, except it initiates it centrally rather than peripherally.

*None of this means glycine replaces sleep hygiene or addresses underlying sleep disorders. .
