Healthy habits and hygiene (a balanced and sufficient diet, physical exercise, rest, stress control) can help to strengthen the immune system, and protect you from bacteria, viruses, and other pathogens. When it comes to fighting viruses, precautions like washing your hands and avoiding those who may be sick are key. In addition, experts say that boosting your immune system will give you a head start on staying healthy.

There are a variety of supplements that come in the form of effervescent (dissolvable) tablets, chewable tablets, or pills that help support your immune system. These include: Vitamin C, Vitamin D, Zinc, Vitamin A, Vitamin B12, Vitamin B6, Copper, Folic Acid, Iron, Selenium

Vitamin C is an important nutrient for the immune system. It cannot be stored in the body, so a regular intake is important to keep the immune system healthy. Natural sources of vitamin C include green, leafy vegetables, tomatoes, kiwi, broccoli, oranges, green beans, and red fruits. The RDA recommends an adult get 80 mg. Since the body cannot store vitamin C, any excess accumulated will be lost in the urine. For this reason, it is safe to consume doses higher than the recommended daily allowance. When taking a food supplement, adults can take up to 1000 mg per day.
