Vitamin C is a water-soluble vitamin that’s found in many foods, particularly fruits and vegetables.
It’s well known for being a potent antioxidant, as well as having positive effects on skin health and immune function.
It’s also vital for collagen synthesis, connective tissue, bones, teeth and your small blood vessels (, ).
