Catechin

Natural polyphenolic antioxidant present in tea and stone fruits.

Definition

Catechin is a polyphenolic flavonoid belonging to the flavan-3-ol family, naturally present in various plants. It is a powerful antioxidant playing a protective role in the organism.

How it works

Catechin is a complex organic molecule resulting from plant secondary metabolism. It has several hydroxyl groups that confer remarkable antioxidant properties. Present in large quantities in unfermented green tea, it survives heat better than fragile compounds. It can cross the intestinal barrier and circulate in the body to exert its protective effects. Catechin is often considered one of the major beneficial compounds in green tea.

Role

It neutralizes free radicals and contributes to the prevention of oxidative stress and chronic diseases.

Examples

  • Green tea
  • White tea
  • Apples
  • Black raisins
  • Peanuts
  • Chocolate

Recommendations

Consume regular unsweetened green tea to benefit from catechins. Prefer infusions for shorter times (2-3 minutes) to preserve heat-sensitive compounds. Associate them with foods containing vitamin C to optimize absorption.

Key takeaway

Catechin is a powerful natural antioxidant whose benefits are maximized by regular consumption of high-quality green tea.
