The immune system works to defend your body against attacks by “foreign” invaders (e.g. bacteria and viruses) that can cause infections. Research has shown that nutrition plays a major role in maintaining a healthy immune system. Important dietary components include protein plus selected vitamins and minerals.
There are two key vitamins present in vitalimmunity® products that support a healthy immune system:
- Vitamin C, also known as ascorbic acid, is a water-soluble vitamin and unlike many animals, humans do not have the ability to make their own vitamin C. Therefore, we must obtain vitamin C through our diet. One way in which vitamin C may support the immune system is through its antioxidant activity. Although many people think of citrus fruits as an excellent source of vitamin C it is also present at high levels in many vegetables.
- Vitamin A is a fat-soluble vitamin which comes in a number of forms — pre-formed vitamin A is found only in animal-derived foods but fruits and vegetables contain selected carotenoids that have provitamin A activity.
