Is it possible for levothyroxine to cause weight gain? It may seem impossible that a medication that is supposed to help improve your metabolism may lead to weight gain and yet that is exactly what we see in many thyroid patients (maybe even yourself). So the question really becomes, is there a plausible explanation as to why levothyroxine may cause weight gain in some people and the answer to that question is yes. The way it may happen is through the conversion of t4 thyroid hormone into the active thyroid hormone t3. What you may not realize is that levothyroxine contains the inactive thyroid hormone t4 which means, in order for it to work, it must be converted into the active t3 thyroid hormone. If it’s not converted then you won’t see the results or improvement you are looking for. To make matters worse, if you don’t convert it well then you may end up creating an inactive thyroid metabolite known as reverse t3. Reverse t3 can act to block what little t3 you do have in your body leading to hypothyroid symptoms. Is there anything you can do to prevent this issue from occurring? Yes! One easy way is through the use of supplements. Certain supplements, such as zinc, selenium, and guggul extract can help support this conversion process and may help to reduce reverse t3. You can see an example of to use these ingredients to support this process in t3 conversion booster: https://www.restartmed.com/product/t3-conversion-booster/ . It contains all of the ingredients you need to at the right doses and in the right formulations. Combining these nutrients with things like regular exercise, a whole food diet, and the right type of thyroid medication can help you optimize your t3 levels and take control of your thyroid. By the way, this conversion process is important for ALL thyroid conditions including those with Hashimoto’s, those with hypothyroidism, those without a thyroid and those post radioactive iodine ablation. #thyroid #hypothyroidism #thyroidsupport #hashimotos #levothyroxine
