These 500mg tasty chewable C wafers are great for kids and adults too! Natural Factors uses only natural sweeteners and flavours. Once you"ve tasted our Chewable Cs you won"t switch. The body"s need for vitamin C increases during times of stress because vitamin C participates in the production of vital chemicals such as norepinephrine, needed for the "fight or flight" response. Vitamin C also acts as a detoxifier, helping to cleanse the body of toxins, such as cigarette smoke, carbon monoxide, etc. Natural Factors includes bioflavonoids in their vitamin C products. Bioflavonoids (vitamin-like molecules that are found in the peel of citrus fruits and other fruits and vegetables) enhance the activity of vitamin C and may improve the body"s ability to hold and absorb vitamin C by 35%.
