Magnesium is an element found in every organ in the human body. Magnesium plays a part in more than 300 reactions in the body. It is necessary to synthesize proteins, DNA and RNA. It plays a role in our metabolism, and cells use magnesium to transport calcium and potassium ions across the cell walls in the body. Optimal magnesium levels are key to nerve function, muscle contraction, heartbeat, and healthy bones.

Magnesium supplements are also claimed to improve athletic performance, decrease anxiety levels and treat sleep troubles including restless leg syndrome and insomnia. Low magnesium levels have been linked to osteoporosis, anxiety, irritability, depression and attention deficit hyperactivity disorder (ADHD).

Magnesium is a mineral that needs to be consumed in relatively large amounts, at least 200 milligrams (mg) per day. An adequate intake can help prevent problems with bones, the cardiovascular system, diabetes, and other functions in the body.
The following health benefits have been associated with magnesium:

1. Bone Health:

Magnesium is important for bone formation which helps assimilate calcium into the bone and plays a role in activating vitamin D in the kidneys. Optimal magnesium intake is associated with greater bone density, improved bone crystal formation, and a lower risk of osteoporosis after menopause in women.

2. Calcium Absorption:

Calcium and magnesium are important for maintaining bone health and preventing osteoporosis condition. Without magnesium, a high intake of calcium mineral can increase the risk of arterial calcification and cardiovascular disease, as well as kidney stones.
