Description
Bitiron is a synthetically derived thyroid hormone replacement therapy formulated with Levothyroxine Sodium (T4) and Liothyronine Sodium (T3) in a 4:1 ratio by weight. This combination mimics the natural secretion of thyroid hormones and is designed to restore proper thyroid function in individuals with hypothyroidism or other thyroid-related deficiencies.
Originally developed when it was believed that both T4 and T3 were secreted in equal proportions by the thyroid gland, modern research shows that the thyroid primarily releases T4, with most T3 produced by conversion from T4 in peripheral tissues. Despite this, Bitiron remains a valuable treatment option for those requiring direct T3 supplementation to achieve optimal thyroid balance.
How It Works
Bitiron contains two critical thyroid hormones:
-
Levothyroxine Sodium (T4): The major hormone secreted by the thyroid gland, responsible for maintaining steady hormone levels and acting as a precursor for T3.
-
Liothyronine Sodium (T3): The active form of thyroid hormone that directly influences metabolism, energy production, and cellular activity.
Together, these hormones enhance oxygen consumption, stimulate energy metabolism, and increase the basal metabolic rate. They regulate the metabolism of carbohydrates, fats, and proteins, supporting essential bodily functions such as cardiovascular health, nervous system performance, and cell development.
Key Benefits

-
Enhances mental clarity, focus, and mood
-
Promotes overall vitality and well-being
-
Aids proper development and differentiation of body tissues
Scientific Background
Thyroid hormones are tyrosine-based molecules containing iodine, essential for proper metabolic function.
-
T4 (Thyroxine) acts as a reservoir that converts to T3 (Triiodothyronine), the more active hormone.
-
T3 binds to nuclear thyroid receptors, activating genes responsible for protein synthesis and energy metabolism.
-
These hormones influence nearly every organ system, with significant roles in growth, development, and metabolic regulation.
By providing a balanced supply of both T4 and T3, Bitiron helps normalize thyroid hormone levels and improve overall metabolic efficiency.
