Vitamin D: The Sunshine Pro-Hormone

Sunshine can protect us from viral infection and lower the risk of getting infections. Just 10 minutes of sun exposure can produce thousands of units of vitamin D.

Vitamin D plays an essential role in the immune system — it interacts with macrophages, B and T lymphocytes, and neutrophils.

When safe sun exposure isn't possible, supplementation matters, especially in northern climates and through winter months.
