TRIIODOTHYRONINE is one of the two main hormones secreted by the thyroid gland – the other being thyroxine (T4). These hormones are crucial for maintaining the proper functioning of the body, as they affect a variety of processes, such as:

  • Controlling metabolic rate
  • Regulation of growth
  • Energy production
  • Supporting nervous system function

How does work?

Triiodothyronine works at the cellular level, affecting protein synthesis and controlling the metabolic rate. As such, T3 plays an important role in energy processes, accelerating the metabolism of fats, proteins and carbohydrates. It also acts on thermogenesis, or heat production, which is important for athletes who train in cold conditions.

The importance of triiodothyronine for people who train

For physically active people, especially athletes, proper triiodothyronine levels are crucial for several reasons:

Supporting energy processes – T3 speeds up metabolism, allowing for more efficient fat burning and better energy utilization.

Increasing muscle mass – due to its effect on protein synthesis, T3 can promote muscle growth, which is important for athletes.

Improved endurance – triiodothyronine optimizes energy processes, allowing for longer and more intense workouts.

Dosage: as indicated by your doctor.
