25-Hydroxyvitamin D LCMS D2+D3
This test measures your total vitamin D status by quantifying both D2 (from plant sources and supplements) and D3 (from sun exposure and animal sources). It's the gold-standard marker for assessing whether you have adequate vitamin D for bone health, immune function, and calcium absorption.
Vitamin D supports muscle function, bone density, and immune resilience—all critical for training capacity and injury prevention. Athletes in northern climates, those training indoors, or with limited sun exposure often run low; adequate D3 levels correlate with better recovery, reduced upper-respiratory infection risk during heavy training blocks, and optimal calcium metabolism for bone strength.
