Found in many common teas like green tea, black tea, and oolong tea, catechins are primarily known for their ability to reduce oxidative stress. An increasing number of clinical trials have associated the intake of catechins-rich foods with the prevention and treatment of chronic conditions.
In clinical trials, green tea catechins have been used in the treatment and prevention of various models, and without adverse effects. The majority scientific opinion is that a daily intake of green tea catechins is beneficial to overall human health.
In addition a dietary supplement with green tea catechins can naturally promote weight loss by suppressing appetite and promoting healthier digestion.
Dietary sources like teas are filled with antioxidants, vitamin c, and other essential nutrients. Green tea leaves in particular are known for their high catechin content, and have been used in natural medicines throughout history to tame free radicals and reduce oxidative stress and chronic inflammation.
Green tea extract is another natural remedy that is being incorporated into clinical trials because of the power of catechins. There is not as much available data on the clinical possibilties of catechins as much as other plant polyphenols, but many laboratory studies are currently exploring their anti-aging potential and their impact on human health.
The effects of tea and green tea catechins on biomarkers of oxidative stress, especially oxidative DNA damage, appear very promising in animal studies. Similarly to other plant polyphenols, the role of catechins in biological processes centers on cellular protection and repair.
In humans, catechins and NMN can similarly provide protective, restorative effects by mimicking the NAD+ levels that naturally occur during these processes.
