While purchasing mineral supplements, have you ever wondered: what is magnesium? This mineral has gained popularity recently, especially for its role in women's health.

Magnesium helps with muscle contraction, nerve impulse generation, conduction of nerve impulses, and energy production. This mineral also plays a significant role in regulating blood glucose levels, decreasing inflammatory conditions, maintaining bone mineral density, and promoting better sleep quality.

The Institute of Medicine of the National Academies - Food and Nutrition Board -determines the Recommended Dietary Allowance of this mineral for individuals of all ages. So, what is magnesium, and how does it benefit your body? Read on to find out.

Hypomagnesemia is generally acute and ignored by most people. An untreated deficiency in the mineral can lead to severe disorders.

Chronically low levels of magnesium can increase risk of common disorders. Common signs of magnesium deficiency include occurrence of frequent cramps in muscles, chronic headaches, elevated blood glucose level, weakness, fatigue, reduced bone mineral density, and breathing problems.

Which Foods are Rich in Magnesium?

Bioavailability is an important factor while choosing the right food. Meat and poultry contain the highest amounts of bioavailable minerals, which can be absorbed easily. However, nuts and seeds are excellent sources for vegans and vegetarians.

Vegan and vegetarian sources of magnesium include:

  • flaxseed
  • sunflower seeds
  • chia seeds
  • cashews
  • hazelnuts
  • oats
  • coffee beans
  • pumpkin seeds
  • almonds
  • cocoa or cacao
  • peanuts

So, what is magnesium, and what causes its deficiency?

Evidence-based benefits of magnesium include:

1) Prevention of chronic headaches

Magnesium helps the nervous system and can prevent chronic headaches. Minerals are required for communication between nerve cells. The deficiency of these minerals is associated with headaches and inflammation.

2) Prevention of muscle cramps

Low levels of magnesium can lead to high levels of calcium in muscle cells, which results in cramps, especially in the abdominal area. A deficiency in other minerals can also cause muscle cramps.

3) Prevention of osteoporosis

Osteoporosis is a bone degenerative disorder characterized by decreased bone density and porous bones. It usually occurs in middle-aged women and older men. It has to be kept in mind that a deficiency of vitamin D (cholecalciferol) and vitamin K also causes osteoporosis.

What Is Magnesium? Supplements to Consider

If you're looking for over-the-counter supplements, go for magnesium glycinate for better bioavailability. Magnesium citrate can also be taken as a dietary supplement.
