Vitamin C functions
Importantly, vitamin C is also able to regenerate other antioxidants such as vitamin E. Vitamin C is required for the synthesis of collagen, the intercellular ‘cement’ substance which gives structure to muscles, vascular tissues, bones, tendons and ligaments. Due to these functions, vitamin C – especially in combination with zinc – is also important for the healing of wounds.
In addition, vitamin C contributes to the health of teeth and gums, preventing haemorrhaging and bleeding. It also improves the absorption of iron from the diet. vitamin C is also needed for the metabolism of bile acids which may have implications for bloodcholesterol levels and gallstones. Moreover, vitamin C plays an important role in the synthesis of several important peptide hormones, neurotransmitters and carnitine.
Vitamin C is also a crucial factor in the eye's ability to deal with oxidative stress, and can delay the progression of advanced age-related macular degeneration (AMD) and vision-loss.
In a nutshell, the main functions of vitamin C are:
- Immune stimulation
- ‘Cement’ for connective tissues
- Wound healing
- Teeth and gum health
- Iron absorption
- Eye health
