THYROFIT 150MG TABLET is primarily indicated for the treatment of hypothyroidism or low secretion of thyroid hormone. It comprises levothyroxine, which is a synthetic thyroid hormone that is chemically similar to thyroxine, which is produced by our thyroid glands. Levothyroxine helps to replace missing thyroid hormones and/or relieve stress on the thyroid gland.

THYROFIT 150MG TABLET minimizes symptoms of low thyroid hormones like unknown weight gain, fatigue, sensitivity to the cold and many more. Thus, it helps in replacing the body's own natural thyroid hormone, which is essential for maintaining both mental and physical health.
