HD Muscle D3 is a high potency Vitamin D3 supplement designed to help support healthy vitamin D levels year round, especially for people who get limited sun exposure. Since only a small portion of vitamin D typically comes from diet, supplementation can be a simple way to support daily wellness and performance.
Vitamin D plays an important role beyond calcium absorption, supporting key functions that matter for both health and training. Adequate vitamin D status helps support immune function, muscle function, workout recovery, and overall muscular remodeling.
Vitamin D also supports healthy hormone balance in both men and women, including support for total testosterone, free testosterone, sperm quality in men, and healthy estrogen levels.
Each capsule provides 2000 IU (50 mcg) of Vitamin D3. Take as directed.
