Micronutrients & recovery
Screening for vitamin D deficiency is recommended for individuals at risk but not for the general population, with deficiency defined as serum 25(OH)D below 20 ng/ml.
If you have risk factors like obesity, dark skin, malabsorption issues, or are elderly, get your Vitamin D levels checked. If you are generally healthy with no risk factors, routine screening is not recommended by current guidelines.
