Some popular weight-loss supplements contain a synthetic compound that is chemically similar to the drug amphetamine, according to a new study by researchers at the Food and Drug Administration.

However, the FDA has yet to take action regarding the findings, leading some scientists to criticize the agency.

In the new study, the FDA analyzed dietary supplements that were labeled as containing Acacia rigidula, a shrub native to Texas. Products whose labels claim to contain Acacia rigidula are commonly marketed for weight loss, supposedly by suppressing appetite and burning fat.
