C-Max by Douglas Laboratories supplies a high dose of vitamin C in a slow release tablet.


Vitamin C (ascorbic acid) has numerous biological functions. Foremost, it is essential for the synthesis of collagen which is the building material of all connective tissues, such as skin, blood vessels, tendons, joint cartilage and bone. ┬áVitamin C is the required coenzyme for two groups of enzymes that catalyze the crosslinking of collagen fibers – lysyl hydroxylases and prolyl hydroxylases.

As such, vitamin C is essential for normal wound healing and capillary health. It also participates in the biosynthesis of carnitine, serotonin, and certain neurotransmitters, including norepinephrine. Vitamin C is among the most powerful antioxidants in humans and animals. It is a water-soluble, chain- breaking antioxidant that reacts directly with superoxide, hydroxyl radicals, and singlet oxygen.


C-Max may be a useful dietary supplement for individuals wishing to supplement their diet with high potency Vitamin C in a slow release tablet.
