Do you take Synthroid or levothyroxine but continue to have symptoms of hypothyroidism?
One of the most common reasons that many people don’t feel great on T4 only medications (such as Synthroid or levothyroxine) is that their body is doing a poor job turning their medication (T4) in the active thyroid hormone T3. In order to feel energized, maintain your weight, and feel your best, you need high levels of T3 hormone which is the active thyroid hormone.
You can take medications which make your TSH and even T4 levels “normal” but if no one is testing your Free T3 levels you have no idea if your body is actually converting your medication into the active hormone.
Why do so many women struggle to convert their medication to T3? Well, there are several factors which can quickly derail conversion of T4 to T3.
Here are the most common factors that reduce conversion of T4 to T3:
- Deficiencies of selenium, iodine, zinc, vitamin A, and vitamins B2, B6 & B12
- Increased stress and high cortisol
- High levels of cadmium, mercury, lead and fluoride
- Starvation or very restrictive eating patterns
- High carb/low protein diet OR very low carb diets
- Chronic illness
- Kidney or liver disease
- Certain medications: beta blockers, birth control pills, estrogen
