Magnesium is a micronutrient that plays a role in human metabolism, the structural maintenance of genetic material in the cell nucleus, and is also a constituent of bones.
Sometimes, excessive loss of magnesium can occur due to the use of certain medications used in cancer treatment, such as cisplatin, which can lead to cardiovascular changes, weakness, cramps, and tremors. However, low levels of magnesium in the blood can be addressed with supplementation of this micronutrient.
