Polyphenols are antioxidants usually naturally present in plants. They prevent cells from damage and promote their growth. More than 8,000 varieties of polyphenols have been discovered, like phenolic acids, flavonoids and more. Along with this, they act as a main colouring agent to plants and help in reproduction.
