The Vitamin Deficiency That Slows Muscle Growth #bodybuilding #fitness #vitamin #muscle

Vitamin D, the sunshine nutrient, plays a powerful role in muscle growth. It supports protein synthesis and muscle repair, keeping your fibers strong and resilient.

Don’t let low vitamin D block your progress.
