Today I want to share 3 specific nutrients that I make sure to check in every single thyroid patient I see. These nutrients tend to be chronically low in most people with thyroid conditions and this alone can be a major contributing factor to symptoms like fatigue, brain fog, hair loss, muscle aches and more. The first step in many of my treatment plans is to improve these nutrients to optimal levels as it often gets people feeling better than they have in a long time!
1. Ferritin (Iron levels)
Hypothyroidism and low iron often go hand in hand. We can test your iron levels by looking at ferritin, a measure of iron stores in your body. The most common signs of low iron include fatigue, hair loss, feeling cold, weak or brittle nails, and palpitations or shortness of breath. Your thyroid also requires adequate iron levels for two key enzymes that are vital to thyroid hormone production and activation. Without iron, your thyroid just can’t function properly.
If you experience heavy menstrual periods (common with low thyroid function), are vegan/vegetarian, or have a chronic digestive disorder it’s even more important to have your ferritin assessed on a regular basis.
2. Vitamin B12
Vitamin B12 deficiency is frequently reported in those with thyroid conditions and I certainly see this in practice. A 2014 study stated that over 55% of patients with an autoimmune thyroid condition had low B12 levels. A series of Vitamin B12 injections often does wonders for thyroid patients in terms of energy levels, memory and concentration, as well as aches and pains.
We get most of our B12 from our diet in the form of animal products, so if you are vegan or vegetarian you should definitely have your B12 checked more often.
Another condition called Pernicious Anemia commonly co-exists with autoimmune thyroid disorders. If you have pernicious anemia your body is unable to absorb B12 from food sources and you will require supplementation long term.
3. Vitamin D
Most of us know that Vitamin D can be helpful for our immune system, but did you know that it is also an essential vitamin for preventing and healing thyroid conditions?
Low vitamin D levels have been implicated in the development, severity, AND progression of autoimmune thyroid conditions such as Hashimoto’s Disease and Grave’s disease. Vitamin D can also be anti-inflammatory for the thyroid and has a role in reducing thyroid specific antibodies.
Symptoms of Vitamin D deficiency include fatigue, muscle/joint pain, and frequent colds and infections. Our body makes its own Vitamin D but only with exposure to the sun. Many of us (especially as Canadians) are vitamin D deficient and require supplementation.
Test, don’t guess!
All of these important nutrients can be tested accurately with a simple blood test. Remember to check your labs carefully or review them with a knowledgeable health professional to make sure they are optimal, and not just falling within the ‘normal’ range. Your Medical Doctor or Naturopathic Doctor can run these tests, ideally alongside a full thyroid panel, which I talk about HERE.
Take good care!
