Magnesium is an essential mineral that plays a role in nerve and muscle function, bone development, blood sugar control, and heart rhythm consistency. It can also help with sleep. However, there isn't an optimal magnesium dosage for sleep. Sleep specialist Dr Chester Wu recommends patients take 400 to 500 mg of magnesium oxide, 250 to 500 mg of magnesium citrate, or 200 to 400 mg of magnesium glycinate. The recommended daily allowance (RDA) of magnesium varies depending on your age and biological sex.

Recommended daily allowance (RDA) of magnesium varies depending on age and biological sex
The recommended daily allowance (RDA) of magnesium varies depending on age and biological sex. For example, the National Institutes of Health recommends a daily dietary intake of 310–320 milligrams (mg) of magnesium for adult women and 400–420 mg for adult men.
Sleep specialist Dr Chester Wu recommends patients take 400 to 500 mg of magnesium oxide, 250 to 500 mg of magnesium citrate, or 200 to 400 mg of magnesium glycinate. However, Dr Wu also advises sticking to a maximum of 500 mg of elemental magnesium (the actual amount of magnesium in a supplement that is available for absorption by the body) a day to minimise side effects.
There isn't an optimal magnesium dosage for sleep, and it's best to start with a low dose and adjust it based on need or side effects. The tolerable upper intake level for supplemental magnesium is 350 mg a day, but this is the amount you can tolerate without getting side effects, not the best amount of magnesium to take.
Magnesium is found in foods like nuts, leafy greens, whole grains, dairy, and soy products. Consult your doctor before adding any supplements to your diet.

The tolerable upper intake level for supplemental magnesium is 350 mg a day
Sleep specialist Dr Chester Wu recommends patients take 400-500 mg of magnesium oxide, 250-500 mg of magnesium citrate, or 200-400 mg of magnesium glycinate. However, he advises patients to start with a low dose and adjust it based on their needs and any side effects. Dr Wu also suggests sticking to a maximum of 500 mg of elemental magnesium (the actual amount of magnesium in a supplement that is available for absorption by the body) a day to minimise side effects.
It's important to note that there isn't an optimal magnesium dosage for sleep, and more research is needed to determine the best dosage. This may depend on whether you have a magnesium deficiency, a sleep disorder, or other health issues, as well as the type of supplement you're taking. It's always a good idea to consult your doctor before adding any supplements to your diet.
