Melatonin 5mg
5mg is more melatonin than most people need. Research shows 0.5-3mg often works better. Break these in half. At $4 for 120 tablets (or 240 half-doses), this is absurdly good value. Just remember: more melatonin doesn't mean more sleep.
6.5/10
GOODMelatonin at 5mg is above the diminishing returns threshold of 3mg and well above the 1mg optimal dose. Research consistently shows lower doses (0.3-1mg) are more effective for sleep onset with fewer side effects. However, 5mg is widely used, safe, and tablets can be split. At $4 for 120 tablets, the value is genuine. Works but overshoots the optimal dose by 5x.
