Benefits
Healthy blood pressure
A meta-analysis of randomized trials found magnesium supplementation modestly lowered blood pressure, supporting cardiovascular health.
Muscle and nerve function
Magnesium supports normal muscle relaxation and nerve signaling, helping reduce cramps and tension.
Bone and sleep support
Magnesium contributes to bone structure and supports a calm nervous system and restful sleep.
Mechanism of action
Enzyme cofactor
Magnesium is a cofactor for hundreds of enzymes governing energy production, muscle function, and nerve transmission.
Vascular and calcium balance
Magnesium helps relax blood vessels and balances calcium's actions in muscle and nerve cells.
Clinical trials
Meta-analysis of randomized double-blind placebo-controlled trials of magnesium supplementation on blood pressure. (Zhang et al. 2016, Hypertension)
Adults across multiple trials.
