Vitamin D is needed for a healthy immune system. But can it help you get over your cold faster?

Vitamin D is an integral part of your immune system, and not having enough could put you at higher risk of respiratory tract infections (RTIs) such as the flu and the common cold. Unfortunately, results are mixed when it comes to taking vitamin D supplements for the prevention and treatment of RTIs. People who are deficient in vitamin D may experience the most immune-protecting effects from vitamin D supplements, but the evidence is limited.

Even though vitamin D supplements may not stop a cold in its tracks, getting enough vitamin D does help optimize your immune system. For best results, strive to get the Recommended Dietary Allowance of vitamin D (600 IU) on a daily basis, not just when an illness is coming on. "Vitamin D, the sunshine vitamin," can be harder to obtain in winter, when it’s cold and cloudy and most people spend more time indoors, but you can get vitamin D from foods such as fatty fish and fortified milk, yogurt, and juice. Ask your doctor to test your vitamin D status before you take vitamin D supplements.
