Magnesium and Sleep: What the Evidence Can Say

A basic guide to magnesium, dietary intake, limits, and medication interactions.

Magnesium has many roles

Magnesium is an essential mineral involved in normal muscle and nerve function, blood glucose regulation, blood pressure regulation, and other processes. It is found in foods such as legumes, nuts, seeds, whole grains, and leafy green vegetables.

Do not assume more is better

Evidence that magnesium supplements help sleep is not strong enough to treat them as a general solution for insomnia. NIH's Office of Dietary Supplements lists an adult upper limit of 350 mg per day for magnesium from supplements and medications, not magnesium naturally present in food. This is not a personal target or a recommendation to take that amount.

Magnesium can affect medicines

Magnesium can reduce absorption of some oral bisphosphonates and certain antibiotics. Diuretics and proton-pump inhibitors can affect magnesium status. The Sleep Revive sales page describes magnesium glycinate but its searchable text does not state a verified amount per serving. Read the current bottle label.
