A nutritional requirement should not be confused with proof that extra supplements improve sleep.

The mechanism

Magnesium participates in enzyme systems and normal nerve and muscle function.

Where it may apply

Dietary adequacy and identified deficiency are clearer contexts than a universal bedtime supplement.

Limits & context

A small review of older adults with insomnia found low-certainty evidence, with uncertain total sleep-time effects.

Context before use

Supplements can cause diarrhea and interact with medicines; impaired kidney function increases toxicity risk.
