Quick answer: Magnesium and melatonin do different jobs. Magnesium is a mineral that supports muscle relaxation and normal nervous system function — think “calming the body.” Melatonin is a hormone that signals the body it's time to sleep — think “setting the timing.” Many people use magnesium nightly as a foundation and add melatonin when their schedule needs extra structure; the two are commonly combined.
What magnesium does
Magnesium contributes to normal muscle and nerve function and is involved in over 300 enzyme systems (NIH ODS). The glycinate form is preferred for evenings because it's well absorbed and gentle on digestion. It suits people whose sleep issue feels like “can't physically unwind.” Product: Magnesium Glycinate, 120 capsules · Guide: how magnesium glycinate is used for sleep.
What melatonin does
Melatonin is produced naturally as light fades; supplemental melatonin supports the sleep-wake cycle, which is why it's popular for shifted schedules, travel, and inconsistent bedtimes. It suits people whose issue feels like “my body doesn't know it's bedtime.” Our Sleep Aid Formula combines 10mg melatonin with chamomile, lemon balm, GABA, and L-theanine.

Frequently asked questions
Can I take both?
Yes — they're frequently paired: magnesium 30 minutes before bed, melatonin formula at lights-out. Both are included with ashwagandha in the Sleep & Stress Support Trio.
Which should I try first?
If unwinding is the problem, start with magnesium; if timing is the problem, start with a melatonin formula. See all options in Sleep Support.
Is either habit forming?
Magnesium is a dietary mineral, and our melatonin formula is non-habit forming by design.
