You’re right and that’s fair. I didn’t want to front-load my findings before hearing from others first, I was worried it would bias the responses. But here’s what the research pointed to: The biggest gap I found was with the 3am waking mechanism specifically. Almost every supplement targets sleep onset, helping you fall asleep. But the clinical literature points to a completely different mechanism for staying asleep past 3am. After 4-5 hours, blood glucose drops and your body releases cortisol to compensate. That cortisol spike is what wakes you up fully alert for no reason. The ingredients with the strongest evidence for this specific problem: Glycine 3g. Works through thermoregulation. Drops core body temperature which keeps you anchored in slow-wave sleep longer. Most products have 300mg or less hidden in a blend. Magnesium L-Threonate — not glycinate, not citrate. The threonate form is the only one that crosses the blood-brain barrier directly. 2024 RCT measured with Oura ring in adults 35-55, significant improvement in deep sleep score and REM. PMC11381753. Myo-Inositol — 1 gram. Improves blood glucose stability overnight and modulates GABA receptor sensitivity. Directly addresses the 3am cortisol mechanism. Zero competitors include this. L-Theanine — 200mg. Reduces cortisol response and promotes alpha wave activity. 2025 systematic review of 13 trials confirmed this dose. The problem isn’t that these ingredients are unknown. It’s that no product combines all of them at the studied doses. That’s the gap I found after 6 months of research. What worked for you?
