Thyroid Function and Magnesium

'The thyroid cannot function without magnesium. Here is a list of very important functions of magnesium and how it relates to your thyroid gland health.

Magnesium is responsible for converting the inactive T4 thyroid hormone into the active form of T3. This is extremely important because the metabolism of your body cells are enhanced by T3, not inactive T4.

Magnesium deficiency is related to goiter, or an enlarged thyroid gland. Another important nutrient in preventing goiter is iodine, but magnesium is right there helping too.

Magnesium helps you to make more T4 in the thyroid gland. Without magnesium, many of the thyroid enzymes that make thyroid hormone simply could not function.'

  • Looks like a useful link. Note that if you were getting insuffient T4 to T3 conversion due to magnesium deficiency the pituitary would have impaired T4 to T3 conversion and consequently the TSH would go sky high. I doubt that magnesium deficiency has any effect on deidinase in practice. However, hypothyroidism leads to reduced intracellular magnesium levels which will not be detected by blood tests. Magnesium is of great benefit so supplement if you suspect symptoms of magnesium deficiency.
