Vitamin C May Boost Absorption of Green Tea's Antioxidants

By October 2, 2009

Follow me on:

Adding vitamin C to your green tea could help your body absorb the brew's beneficial compounds, according to a new study.

In tests on human intestinal cells, scientists discovered that adding vitamin C or table sugar (or a combination of the substances) to green tea increased the absorption of antioxidants by as much as three times. Also found in fruits, vegetables, and other foods, antioxidants help fight free radicals (chemical by-products known to damage DNA).

Past research suggests that drinking green tea may help prevent tooth erosion, periodontal disease, stroke, and cognitive impairment. However, studies on green's cancer-fighting properties have yielded mixed results. In a 2009 review of 51 studies on the link between green tea consumption and cancer, for instance, researchers found that the tea may decrease prostate cancer risk but might have limited benefits for liver cancer. There was also "limited moderate to strong evidence" for green tea's ability to help prevent lung, pancreatic, and colorectal cancer, and conflicting evidence for cancer of the esophagus.

This is evidence that a little lemon or orange in your tea or along with it is going to be a good companion to the drink. However, the citrus can be hard on your teeth. Adding a small amount of sugar with your tea has similar effects in increasing the healthiness of the tea in digestion but can compromise its dental cleansing of the mouth. –Teaternity

It is probably worth keeping in mind that vitamin C is very sensitive to high temperature, so it make sense to add it only after the tea is no longer hot.
