Magnesium is a
vital macromineral involved in numerous biological processes and over 300
enzymatic reactions. The human body contains approximately 25g of magnesium,
50-60% of which resides in bone, hence it forms part of the structure of bones
and is required for proper bone mineralisation along with the minerals calcium
and phosphorus; absorption is enhanced by vitamin D. It is also involved in aerobic energy
production, protein synthesis, muscle contraction & relaxation and nerve
impulse transmission.

| Magnesium plays a vital role in aerobic metabolism |
Due to its role in muscle contraction, it is essential for the normal rhythm of the heart and as a potent vasodilator (opens up blood vessels) has the ability to lower blood pressure. Studies suggest that coronary heart disease is more common where
magnesium levels in water supplies are low and that magnesium is protective of
cardiac muscle. Research indicates that magnesium can help regular blood sugar levels and a recent study suggests that low magnesium levels are negatively correlated with the development of metabolic syndrome, insulin resistance and type 2 diabetes.
According to Dr Qais Faryadi, magnesium efficiency can reduce depression, irritability, anxiety & tension; he refers to it as "nature's tranquiliser" due to its wonderfully calming effect upon the nervous system. Our bodies use up more magnesium when we are under stress - the more stressed we become, the more magnesium is used up, this results in a vicious cycle as magnesium levels get lower, our stress levels get even higher!
The magnesium
content of food varies substantially, refined and processed foods generally
have the lowest magnesium content; rich sources include green leafy vegetables,
avocado, whole grains, nuts and seeds.

Not all available forms of magnesium supplements are easily absorbed by the body and high doses may cause diarrhoea & stomach upsets, so do take advice prior to taking this or any other single supplement.
A truly magnificent mineral!
