How much magnesium do I need? Men under 30 need 400 milligrams (mg) of magnesium per day and men over 31 need 420mg a day. Women under 30 need 310mg each day and 320mg a day after 31. Pregnant and breastfeeding women, however, need more than that, approximately 350 to 360mg a day.
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. 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.
Too much magnesium from food does not pose a health risk in healthy individuals because the kidneys eliminate excess amounts in the urine [29]. However, high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping [1].
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.
Early signs of excessive magnesium intake can include low blood pressure, facial flushing, depression, urine retention, and fatigue. Eventually, if untreated, these symptoms can worsen and include muscle weakness, difficulty breathing, irregular heartbeat, and even, in very rare cases, cardiac arrest.
Magnesium for sleep
Some studies have found that magnesium supplements can: Make it easier to fall asleep. Improve sleep quality. Reduce symptoms of restless legs syndrome, which can interfere with a good night's sleep.
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.
Medical research has linked magnesium to reduced anxiety. Magnesium helps you to relax by stimulating the production of melatonin and serotonin which boost your mood and help you sleep. Magnesium also reduces the production of cytokines and cortisol, which lead to increased inflammation and stress.
From regulating mood, maintaining healthy heartbeat to supporting sleep, muscle and nerve function along with energy production to name just a few. It's clear the mineral is vital for both men and women.
Long-term magnesium supplementation improves arterial stiffness, a cardiovascular disease risk marker. Effects on endothelial function may be another mechanism whereby increased magnesium intakes affect cardiovascular risk.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
Magnesium supplements should be taken with meals. Taking magnesium supplements on an empty stomach may cause diarrhea.
Magnesium can be a long-term supplement that you can take for years. Nevertheless, you should always check with your doctor to make sure that you're not exceeding the recommended dosage. Your doctor will run regular lab tests to make sure that your magnesium levels are within the normal range.
Generally speaking, you will find that magnesium supplements start to work after one week of using them. After one week of regular magnesium supplementation, individuals may experience benefits such as improved energy levels, reduced muscle cramps, better sleep quality, and reduced anxiety.
One of the side effects of magnesium might be drowsiness. In this case, you should consider magnesium supplementation at the end of the day (with dinner) to prevent the midday magnesium slump.
In addition to those health benefits, magnesium can also aid in weight management. A 2013 study in the Journal of Nutrition found that higher magnesium intake was associated with lower levels of fasting glucose and insulin (markers related to fat and weight gain).
Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys.
So, get enough vitamin D—just take it in the morning or afternoon. At night, take supplements that support sleep quality and muscle relaxation, like magnesium and melatonin (which you'll find in soothing, sippable Bulletproof Sleep Collagen Protein).
Melatonin vs Magnesium for Sleep
Magnesium helps regulate muscle relaxation, hormone production, inflammation levels, and energy metabolism, all contributing to better sleep quality. Meanwhile, melatonin helps reset your internal body clock, so you can fall asleep quickly and stay asleep for extended periods.
Magnesium glycinate -- Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea. It is the safest option for correcting a long-term deficiency.
