What is this test

Magnesium normally exists in the bone and inside cells of body tissues and organs. It is an essential element in most processes in the body. It helps maintain normal muscle and nerve function, keeping bones strong, controls the heart beat and helps regulate blood pressure. Magnesium also balances blood sugar levels and helps support the immune system. Green vegetables like spinach; whole grains, and nuts are a rich source of Magnesium.
