Catechin
Description: Catechin is a bioflavonoid that is found in Green Tea. It works both alone and in conjunction with other flavonoids found in tea, and has both antiviral and antioxidant qualities.
Catechin has been shown helpful in the treatment of viral hepatitis.1 Supplementation of 500 to 750 mg three times daily appears effective.
It also appears to prevent oxidative damage to the heart, kidney, lungs, and spleen.2
Preliminary studies of animals show that catechin prevents oxidative damage to blood as well.3
When taken as part of Green Tea, catechin also appears to inhibit the growth of stomach cancer cells.4

Natural Sources: Green Tea.

Useful in treatment of: antioxidant Damage, hepatitis.

Recommended Dosage: Several cups of Green Tea daily, or supplementally 500 to 750 mg three times daily.

Contraindications: Catechin should not be taken with Iron, as the combination may cause red blood cell damage. Long-term supplementation with catechin may also cause problems.5
