Why does REM Sleep use 1mg of melatonin instead of higher doses?

Most sleep supplements pack in 5-10mg of melatonin, but research suggests that’s far more than your body needs - and too much can cause next-day grogginess, headaches, and irritability. Studies show as little as 0.3mg is sufficient to signal your body toward sleep. HealthyCell’s REM Sleep uses 1mg of melatonin, combined with multiple other sleep-supporting nutrients like GABA, L-theanine, 5-HTP, magnesium, lemon balm extract, L-glycine, Vitamin B6, calcium, and more. This multi-ingredient approach is designed to support all four stages of sleep, rather than relying on just a higher dose of melatonin to force drowsiness.
