More About Immune Support

Colds and flu are the most common illnesses among Canadians. Aside from making you feel dreary, these ailments are the leading cause of lost work and school days. Natural source supplements such as vitamin C and vitamin D, and herbals such as echinacea and garlic, can help you take control of and prevent illness by boosting your immune system and reducing cold and flu symptoms.
