Nutrient - Plant source antioxidants

By Nutri People

Plant source antioxidants provides a source of plant-derived antioxidants, including carotenoids, catechins, proanthocyanadins, and curcuminoids.

Carotenoids are naturally occurring pigments found in certain plants with potent antioxidant properties. They are also responsible for the orange, red, or yellow colouration of many fruits and vegetables. The role of carotenoids in plants is to quench free radicals formed during photosynthesis. The most common dietary carotenoids include beta-carotene, lutein and lycopene. Astaxanthin is a pink carotenoid derived from algae with powerful antioxidant properties.

Catechins are also known as flavanol monomers. Catechins are antioxidants, and are probably largely responsible for the reported antioxidant effects of green tea.

Proanthocyanadins are flavanol polymers with antioxidant and free radical scavenging properties, and are present in tea, apples, berries, red grapes and red wine.

Turmeric is a spice derived from the rhizomes of Curcuma longa. The rhizomes are rich in polyphenolic pigments known as curcuminoids which give turmeric its characteristic yellow colour.  Curcumin is the principal; curcuminoid is found in turmeric and has been shown to have both antioxidant and anti-inflammatory activity.

Alpha-lipoic acid acts as water and fat-soluble antioxidant, and also stimulates production of glutathione, giving cells a double dose of antioxidant.
