Levothyroxine (T-4) is a naturally circulating thyroid hormone produced by the canine thyroid gland. Levothyroxine sodium provided by Thyro-Tabs tablets cannot be distinguished from levothyroxine endogenously secreted from the dog's thyroid gland. Thyroid hormones influence virtually every body organ, either by their effect on growth and development or by the hormones' metabolic effects. 

In light of low canine bioavailability and high absorption variability among individual dogs, reliable dose potency becomes an essential tool toward successful therapy. Advanced Formula Thyro-Tabs is the only veterinary levothyroxine sodium tablet to provide a minimum 95% dose potency guarantee, as recognized by the USP. As such, Thyro-Tabs sets a new therapeutic standard in the treatment of canine hypothyroidism. READ MORE
