Levothyroxine Sodium (Synthroid T4): Understanding Thyroid Hormone Replacement

Synthroid, with the generic name Levothyroxine Sodium, is a synthetic form of the T4 thyroid hormone. Normally, the thyroid gland produces and releases these hormones to regulate the body’s metabolism. In cases of hypothyroidism, where the thyroid gland is underactive, it doesn’t produce enough hormone, leading to a slower metabolism. Synthroid T4 helps supplement this deficiency, restoring balance and supporting normal metabolic function.

Cytomel (T3) and Its Role in Fat Loss

Cytomel (T3) is known to aid in fat loss by increasing metabolic rate. For those looking at Cytomel as a supplement, 12.5 mcg per day is generally considered a conservative dose with minimal impact on natural thyroid function. At 25 mcg per day, some inhibitory effect on the thyroid is observed. Bodybuilders may take 50 mcg per day, which is still fairly conservative but carries more thyroid suppression. Doses of 75 mcg or higher, especially at 100 mcg per day, increase the risk of muscle size and strength loss, with more significant inhibition of natural thyroid function.
