Micronutrients & recovery

Vitamin D supplementation may reduce the severity and risk of COVID-19 infection, particularly in individuals with vitamin D deficiency, by modulating immune response and reducing pro-inflammatory cytokines.

Consider Vitamin D supplementation, especially if you have limited sun exposure or are elderly. Aim for a daily intake of up to 2000 IU, and ensure adequate magnesium intake to support Vitamin D metabolism. Consult a healthcare provider for personalized advice.
