The mineral your body burns through under stress, and almost nobody replaces. Magnesium is required for over 300 enzymatic processes, including HPA axis regulation (your cortisol response) and the conversion of glutamate to GABA, the calming neurotransmitter. NHANES data shows roughly half of US adults consume below the daily recommended intake. Stress, caffeine, alcohol, and intense training all accelerate depletion.† The problem with most magnesium products: they use cheap oxide form that absorbs at 4-10% and acts as a laxative, which is why people quit before they correct the deficiency. Bisglycinate (the form in JevityRx Magnesium Glycinate) absorbs at significantly higher rates without the GI side effects, which is why men actually stay on it long enough to feel the change.† What's inside every serving: 400mg elemental magnesium as bisglycinate 1,000mg L-glycine for sleep onset support 5mg vitamin B6 (P-5-P, the active form) as absorption cofactor 200mg L-theanine for evening nervous system regulation The twist: This isn't a single-ingredient magnesium pill. It's a complete sleep-and-recovery stack designed to layer on the same calm-and-restore pathways. Bisglycinate, glycine, B6, and L-theanine work together rather than in isolation. Take 2 capsules 30-60 minutes before bed. Most men report deeper sleep within 5-7 days. Stress regulation, recovery, and muscle cramp reduction build over the first 2-4 weeks.
