We are completely reliant on our diet to supply our mineral and trace element needs. Minerals are vital to our health in the same way that vitamins are, and some would argue they are even more important than vitamins.
Minerals work in combination with vitamins and affect vitamin uptake and absorption.
Unfortunately crops can be depleted of their mineral content, which can mean that our food is not as dependable a source of minerals as we might hope. In addition, minerals can be lost in the peeling of foods and leached out of food during cooking. Magnesium is a macro mineral and plays an important role in calcium metabolism. It also plays an important role in muscle function and in maintaining the normal working system of the heart. Magnesium is easily depleted from our diet by food processing and refining techniques.
