Green tea weight loss supplements could be dangerous

Consumer Reports says little evidence to support weight loss claims

SAN ANTONIO – They are marketed for weight loss, but Consumer Reports said there is little evidence that green tea manufacturers can back up those claims.

Though green tea is good for the heart, consumers should not confuse it with the green team extract powder. So sellers claim it can help with weight loss.

“Higher concentrations of green tree extract can be really dangerous, because it can potentially cause serious liver damage,” Jeneen Interlandi, with Consumer Reports, said. “The herb itself has been found to alter the effectiveness of a long list of drugs, including antidepressants and anticlogging medications.”

The extract can also raise a person’s heart rate and blood pressure. Research also suggested that up to 10 percent of people who suffer acute liver failure from green tea extract may die as a result.

Buyers also need to know that when it comes to supplements, manufactures are not requires to prove to federal regulators that their products are safe, effective or accurately labeled.

In terms of weight loss, studies have found that even in high doses, green tea extract probably won’t help a person shed those unwanted pounds.

“It is true that green tea can raise your metabolic rate, so you burn more calories, but that is probably just due to its caffeine and catechins it contains,” Interlandi said. “Catechins are antioxidants that are found in green tea.”

Consumer Reports also said most people can reap the health benefits of green tea by drinking a couple cups every day.
