The thyroid cannot function without magnesium.

Karen Fitzpatrick-Dame, ChhC, AADP

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 of the metabolism of your body cells 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.

For supplementation for your thyroid and general health, there are two different categories of magnesium, depending on whether you have constipation or not. If you have constipation, then Magnesium Citrate is best at a dose of 400 mg to 1000 mg to relieve constipation and start to increase magnesium stores.

If you do not have constipation, but many of the other symptoms, then take Magnesium Taurate at a daily dose of 400 mg to 800 mg.

These are two magnesium “amino acid chelates” that help you to increase magnesium stores and will not increase bowel motility for those that do not really need it.

The rest of your body benefits from magnesium too. In fact, there are over 300 different enzymatic reactions in your body and cells that require magnesium. When magnesium is LOW, it gives way to a whole host of health problems:

  • Thyroid problems (low or high)
  • Headaches
  • Muscle aches
  • Fibromyalgia
  • Tingling in the extremities
  • Raynaud’s Syndrome
  • Anxiety and depression
  • Personality changes
  • Fatigue
  • Insomnia
  • Constipation
  • High blood pressure
  • Heart palpitations


Caution: Individuals with KIDNEY (renal) FAILURE should NEVER use any form of magnesium.
