Magnesium is important for over 300 different chemical reactions in the human body. This include glucose metabolism, protein production, and synthesis of nucleic acids such as DNA. According to Medline Plus, magnesium helps to maintain normal nerve and muscle function, support a healthy immune system, keep the heart beat steady, and help maintain bone strength.
A deficiency in the mineral raises the risk of conditions such as endothelial dysfunction, hypertension, and cardiac arrhythmias because the mineral is essential for healthy control of blood vessel function, blood pressure regulation, and normal heart contractions.
This mineral is not just a heart-friendly mineral. It can also ward away depression, migraines, and even PMS symptoms.
The mineral plays an important role in the functioning of our brain and our mood. Low level magnesium is linked to an increased risk of depression.
According to a study of over 8,800 people, those under 65 years of age with low levels of the mineral had a 22 percent greater risk of depression.
Some researchers suggest that a poor diet with low magnesium may be at the root of many cases of depression and mental illness. However, low magnesium-induced depression could be reversed. A separate study found 450 mg of magnesium improved the mood of depressed older adults as effectively as an antidepressant drug.
