Melatonin vs Magnesium Glycinate for Sleep: Which Is Right for You?

Melatonin and magnesium glycinate support sleep in different ways. Melatonin is a hormone that signals timing — it tells your brain the day is ending. Magnesium glycinate is a mineral that supports muscle relaxation and a calm nervous system. Choose by what's keeping you up at night or use them together through their different pathways.

How each supports sleep differently

Melatonin is produced by the pineal gland and acts as a chemical messenger of darkness: light suppresses it, darkness increases it, and that rhythm helps regulate your sleep-wake cycle.*

Magnesium is an essential mineral your body doesn't make, so it comes from a balanced diet and supplements. For sleep, it supports muscle relaxation, healthy GABA activity, and helps maintain cortisol level stay within a normal range — which supports a calm nervous system. Vegan food sources include leafy greens, legumes, nuts, seeds, and whole grains.*

When you might choose one over the other

Can you take them together?

Because they work through different pathways, some people use both — magnesium to help the body relax and melatonin to cue the timing of sleep. Combining supplements is best done with guidance from a qualified healthcare professional.*
