Green tea dangers

WPEC.

Green tea supplements are marketed for weight loss.

But there's little evidence to support those claims.

It could even cause potential health risks.

You may have heard that green tea can be good for your heart.

But don't confuse a cup of tea with green tea extract powder.

Some supplements containing the ingredient are promising weight loss and a healthier metabolism but the experts at Consumer Reports have concerns.

"Higher concentrations of green tea extract can be really dangerous because it can potentially cause serious liver damage. Plus the herb itself has been found to alter the effectiveness of a long list of drugs including certain antidepressants and anticlotting medications," said Jeneen Interlandi of Consumer Reports.

It can also elevate your heart rate and blood pressure.

And researchers suggest that up to 10 percent of people who suffer acute liver failure from green tea extract may die as a result.

Consumer Reports put Green Tea Extract Powder on its list of 15 supplement ingredients to avoid.

"The manufacturers who make these supplements are not required to prove to federal regulators that their products are safe, that they're effective or even that they are accurately labeled, so you really don't know what you're buying," said Interlandi.

Studies have also found that even in high doses green tea probably won't help you lose weight. Instead of taking the supplement Consumer Reports suggest you rap the true health benefits of green tea the old fashion way by just having a couple of cups a day.
