Greatest dietary supplements for immunity: Skilled heralds ‘most necessary’ immune boosting vitamins
Dr. Chris D’Adamo – the director of the Center for Integrative Medicine at the University of Maryland School of Medicine, America – recommends using the following supplements in moderation to keep you in tip-top shape. “Vitamin C can help prevent viral, bacterial, and other infections,” said Dr. D’Adamo. The nutrient is said to shorten the duration of colds (if you do get one) and acts as a “natural antihistamine and anti-inflammatory”.
The NHS guidelines recommend 40 mg of vitamin C daily for adults because the nutrient – also known as ascorbic acid – cannot be stored in the body.
Vitamin C helps protect cells and is critical to maintaining healthy skin, blood vessels, bones and cartilage; the nutrient can also aid in wound healing.
Food sources for vitamin C are:
- Citrus fruits like oranges
- Black currants
- Brussels sprouts
Ingestion of more than 1.00 mcg of vitamin C can cause stomach pain, diarrhea and gas.

Daily vitamin D supplementation in fall and winter is also recommended by the NHS.
“In the fall and winter, you need to get vitamin D through your food because the sun isn’t strong enough for the body to make vitamin D,” the NHS said.
“But since it is difficult for people to get enough vitamin D through diet alone, everyone (including pregnant and breastfeeding women) should consider taking a daily 10 mcg vitamin D supplement during fall and winter.”
Vitamin D helps regulate the amount of calcium and phosphate in the body that is needed to keep bones, teeth, and muscles healthy.
Dr. D’Adamo also recommends taking a “short-term” supplement with vitamin A to help combat a respiratory infection.
Vitamin A, also known as retinol – as noted by the NHS – actually helps the immune system to function properly.
In addition, it keeps the nasal lining healthy and helps your vision in low light.
Food sources for vitamin A are:
- Oily fish
- Fortified low fat spreads
- Milk and yogurt.
