Learn How to Boost Your Thyroid Hormones Naturally
If your body doesn’t produce adequate amounts of thyroid hormones, your metabolism drops, with a resultant drop in energy levels causing severe fatigue.
Weight gain; sensitivity to cold weather; poor skin, hair and nail condition; and a slowdown in brain sharpness, often described as brain fog, are other common symptoms of low thyroid function (medically known as hypothyroidism). Hypothyroidism is much more common in women than in men.
Thyroid Hormone
There are two main thyroid hormones, T4 (thyroxine) and T3 (tri-iodo-thyronine).
T4 is released in the thyroid gland in the neck, in response to TSH (thyroid stimulating hormone).
T4 is then converted into the second thyroid hormone, T3, in the tissues (mainly in the muscles) of the body.
T3 is about 10 times more potent than T4, which means that adequate conversion from T4 to T3 is critical to maintain metabolic rate.
But sometimes this doesn’t happen. One of the main causes of reduced T4 to 13 conversions is if you skip breakfast.
The body interprets this as a food shortage and reduces the formation of T3 in an attempt to reserve the body’s fat reserves, resulting in a drop in metabolic rate.
Therefore, if you are trying to lose weight (and maintain energy levels), never skip breakfast, because it literally kick-starts your metabolism.
Reduced conversion of T4 to T3 also occurs as one gets older.
You can help boost your T3 levels by taking selenium, a mineral that’s essential for the correct conversion of T4 into T3.
The Immune System Link
A malfunctioning immune system can also reduce thyroid hormones in about 50% of cases.
This occurs when the immune system attacks the thyroid gland in what is called an autoimmune attack, reducing the formation of T4. Without T4, you can’t produce T3.
Immune-balancing nutraceuticals such as omega-3s from fish or krill oil (and to a lesser degree flaxseed oil), probiotics and Rhodiola rosea herbal extract help to prevent autoimmune attacks.
Other useful nutraceuticals are gugulipid, an extract from the Indian myrrh tree, which stimulates the thyroid gland to produce T4, as well as iodine and tyrosine (an amino acid), which are the building block precursors that thyroid hormones are comprised of.
Paradoxically, too much iodine can reduce thyroid function, so don’t take more than 300 micrograms (0.3 milligrams) of iodine supplements daily.
Excessively high doses (but not low physiological doses) of estrogen hormone replacement therapy as well as high doses 160mg daily) of soy-isoflavones, or a diet rich in soya products can also reduce thyroid hormone production.
