- Anyone who wants melatonin with a little magnesium glycinate in one vegan capsule
Who this product is NOT for:

Vitamart's Take
This is a melatonin product first, with a modest amount of magnesium glycinate alongside. Each capsule gives 3 mg of melatonin and 100 mg of magnesium glycinate (20 mg elemental magnesium), and the 1–3 capsule dose lets you start low and adjust. Read the cautions before you start: no driving or machinery for 5 hours after a dose, no alcohol alongside it, and talk to your practitioner first if you take seizure, blood pressure, immune-suppressing or blood-thinning medication.
How Magnesium Glycinate + Melatonin Compares
3 mg blend vs. Melatonin 10mg Slow Release
Pure Lab Melatonin 10mg Slow Release is a sustained-release, higher-dose melatonin for adults, with no magnesium. This product gives 3 mg of melatonin per capsule with magnesium glycinate.
Melatonin blend vs. Magnesium Glycinate + L-Theanine
Pure Lab Magnesium Glycinate 150mg + L-Theanine 75mg contains no melatonin — it pairs magnesium with L-theanine for muscle function and relaxation. Choose the melatonin formula if your goal is resetting your sleep-wake cycle.
Blend vs. full-dose magnesium
If magnesium is your main goal, Pure Lab Magnesium Glycinate provides 165 mg of magnesium per capsule, far more than the 20 mg elemental magnesium here.
