What level of vitamin D is recommended for optimal skeletal muscle health?

For optimal skeletal muscle health, a serum vitamin D level of 32 ng/mL is recommended. Vitamin D plays a crucial role in muscle function, strength, and overall health. Research indicates that maintaining this specific level may enhance muscle performance, support muscle cell function, and potentially reduce the risk of falls and injuries, particularly in older adults.

While lower levels, such as 25 ng/mL, might be considered sufficient for bone health, they may not provide the same benefits for muscle function. Higher levels, like 30 ng/mL or 35 ng/mL, may not show additional advantages and can lead to complications if levels become excessive. Thus, 32 ng/mL is seen as an optimal balance to support muscle health without the risk associated with higher concentrations.
