The key function of the thyroid is to help metabolism. T4 is the major hormone produced by the thyroid, which also converts to T3. T3 is five times more active than T4, so it helps regulate metabolism better. However, this conversion can get tricky because selenium is required and if there isn’t enough selenium it won’t covert and you’re left with the less active T4.
The presence of too much cortisol from stress can also stop the conversion. It’s important to remember that you can have adequate amounts of T4 but still experience some thyroid imbalance symptoms due to the lack of more active T3. Those symptoms include fatigue, weight gain, puffiness around the eyes and face, foggy thinking, dry hair and skin, etc. Low thyroid can also cause increased cholesterol and LDLs because you’re not metabolizing fats as well. Heart issues, particularly a higher risk of heart disease, can also occur.
So how can you improve thyroid function? There are several ways. First, there are several nutrients that can help: selenium, zinc, the B vitamins, vitamin A and vitamin C. Reduce stress levels so there is no conversion issue. Avoid toxin exposure to mercury, lead, BPA and phthalates by eating more organic and not drinking out of plastic water bottles and aluminum cans. Fish oil and vitamin D are good because they are anti-inflammatory and the herb ashwagandha stabilizes the adrenals, helps metabolism and lowers cortisol.
