What is magnesium good for?
Magnesium is an essential mineral that is crucial for the normal functioning of the body. It helps with nerve and muscle health, as well as promoting heart health. Magnesium also helps regulate blood sugar levels, aids in digestion, and strengthens bones and teeth. Additionally, it is important for energy production, metabolism, protein synthesis, and DNA repair.
As such, a magnesium deficiency can lead to an array of health problems, including muscle cramps, fatigue, poor sleep quality, and depression. So it is important to maintain adequate levels of magnesium in the body for optimal health.
How much magnesium per day?
The recommended dietary allowance (RDA) for magnesium depends on age and gender. Adult men generally need around 400-420 mg of magnesium per day, while adult women usually need around 310-320 mg. Pregnant and lactating women need more, typically around 350-360 mg and 310-320 mg per day, respectively.
Good sources of magnesium are green leafy vegetables, legumes, nuts and seeds, fish, whole grains, dairy products, and fortified cereals. Taking magnesium supplements can also be helpful in achieving the recommended daily amount of magnesium.
