The Link Between Triiodothyronine (T3) and Bone Density

The Link Between Triiodothyronine (T3)

Triiodothyronine (T3) is an important hormone produced by your thyroid gland. It’s a key regulator of important biochemical processes and has a powerful influence on your overall body composition, energy levels, and metabolism. Evidence suggests that T3 plays an essential role in maintaining bone density and health.

How T3 Affects Bone Density and Health

T3 is important for balancing calcium metabolism in your body. Not enough T3 can lead to negative alterations in how much calcium your body absorbs and retains. This can lead to weaker, more brittle bones and an increased risk for osteoporosis.

Optimal T3 levels have also been associated with increased muscle mass, increased strength, and improved physical performance. With a higher percentage of muscle and less fat mass, the adequate absorption and retention of calcium is more likely and the risk of osteoporosis is decreased.

How to Regulate T3 Levels

People concerned about their T3 levels should follow a healthy lifestyle. Adequate nutrition and regular exercise can help optimize T3 levels. Proper hydration also plays an important role in bone health.

In addition to lifestyle changes, supplements that contain Triiodothyronine (T3) may be helpful for addressing deficiencies and restoring balance. For those wanting to further increase the impact of T3 on bone health, it may be helpful to talk to a healthcare professional about strategies for testing and regulating T3 levels.

What other hormones besides triiodothyronine (T3) affect bone density?

Other hormones that can affect bone density include estrogen, testosterone, parathyroid hormone (PTH), growth hormone (GH), calcitonin, cortisol, and vitamin D.

Estrogen is especially important in post-menopausal women, as it helps maintain bone density. Testosterone plays a role in providing calcium to bones and preventing bone loss. PTH helps with calcium homeostasis and is important for maintaining and regulating bone remodeling. GH helps regulate the activity of other hormones and has been linked to increased bone density and improved bone health. Calcitonin helps with the metabolism of calcium and can help protect and preserve bones. Cortisol helps regulate calcium and phosphorus concentrations, important in maintaining proper bone health and density. Vitamin D helps with calcium absorption and is needed for the production and maintenance of healthy bones.
