CATECHINS: ANTIOXIDANTS BY NATURE
What are catechins?
Catechins are flavonoids that have recognized anti-cancer activity, although its properties are much broader. Among these we could mention anti-arthritic properties, anti-inflammatory, anti-ulcer, anti-, immunostimulant and hepatoprotective.
The richest source of catechins in nature is green tea.
Types of catechins in green tea
The most interesting catechins are epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate, components shown in green tea leaves (Camellia sinensis) so that up to 30 % of dry green tea corresponds to these components. Of these, epigallocatechin gallate is the one having greater antioxidant power.

What kind of tea contains more catechins?
We have to make clear that the amount of catechins contained in green tea is almost double than those that can be found in red tea or black tea. The last two tea types have been subjected to a fermentation that has removed some of these components.
Sources of catechins
Green tea is the only source of epigallocatechin gallate, the major catechin type of antioxidant. Some dietitians recommend the ingestion of green tea extract (especially epigallocatechin gallate) for the body to get the catechins that are necessary. Daily doses of catechins are between 125 and 250 mg daily. Is supplied as a powder, sachets, capsules, etc..
