RDA: The Recommended Dietary Allowance (RDA) for adults 19-51+ years is 400-420 mg daily for men and 310-320 mg for women.
Risks of getting too much magnesium
The daily Tolerable Upper Intake Level (UL) for magnesium for adults is 350 mg.
Magnesium supplementation has been used successfully in the treatment of different conditions such as PMS, PCOS, mood disorders, and postmenopausal symptoms and consequent risk factors, particularly in the association with other dietary components with proven antioxidant and anti-inflammatory activity.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
Taking magnesium with these medications might cause blood pressure to go too low. Some of these medications include nifedipine (Adalat, Procardia), verapamil (Calan, Isoptin, Verelan), diltiazem (Cardizem), isradipine (DynaCirc), felodipine (Plendil), amlodipine (Norvasc), and others.
One study of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep faster, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
Magnesium plays a vital role in health throughout all life stages. During menopause, it's important for keeping bones strong and preventing osteoporosis, or weakening of bones. Magnesium may also reduce unwanted side effects of menopause, such as difficulty sleeping and depression while supporting heart health.
Magnesium levels are lower in obese people and higher in those who are not overweight. High magnesium intake can possibly help you lose weight because it is helps improve insulin sensitivity in your body (20).
Recommended Amounts. RDA: The Recommended Dietary Allowance (RDA) for adults 19-51+ years is 400-420 mg daily for men and 310-320 mg for women. Pregnancy requires about 350-360 mg daily and lactation, 310-320 mg.
Magnesium supplements should be taken with meals. Taking magnesium supplements on an empty stomach may cause diarrhea.
Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
It can also help with menopausal insomnia and other symptoms such as low mood. Yet, surprisingly, adult women do not get enough magnesium from their diet: we need approx 300mg a day (see food sources below).
Magnesium promotes healthy estrogen clearance
By supporting the COMT enzyme (catechol-o-methyltransferase) in the liver, magnesium promotes the healthy excretion of estrogen (9). This may reduce the risk of the estrogen excess conditions (such as fibroids) associated with low COMT function (10).
Magnesium and zinc
All minerals and vitamins need the proper conditions for your body to absorb them properly. When taken together, magnesium and zinc have mutual benefits. Magnesium helps your body regulate its zinc levels, while zinc does the job of allowing it to absorb magnesium more effectively.
Hormone creation – magnesium actually makes your hormones progesterone, estrogen and testosterone, so if you're getting into peri-menopause or just off the Pill and your levels are low, it's a great help to your body.

Magnesium begins to take effect after one week of consistent supplementation.
Yes! You can and should take magnesium and vitamin D together. In fact, the bioavailability of vitamin D largely relies on magnesium. Also, many nutrients wouldn't work efficiently without magnesium, further highlighting the importance of this mineral!
Phytates in the diet bind to magnesium and impair its absorption. However the quantities present in normal diet do not affect magnesium absorption. Other dietary factors that are thought to affect magnesium absorption are oxalate, phosphate, proteins, potassium and zinc.
Magnesium does not react with water to any significant extent. This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water.
