Core Nutritionals brand AMP Citrate
Makers of dietary supplements are at it again, putting a new chemical stimulant – untested on humans — into workout, weight-loss and brain-function products sold widely through retailers including Amazon and GNC. Yet federal regulators have taken no action despite the urging of scientists and a supplement industry group.
The compound, often listed on labels as AMP Citrate, is a close chemical cousin of DMAA — a stimulant the U.S. Food and Drug Administration has warned is an illegal ingredient that carries risks of heart attacks, seizures and neurological conditions. Scientists in the United States and the Netherlands testing several products found that the amount of the new synthetic stimulant varies widely, the dosage isn’t disclosed on labels, there’s scant evidence the chemical is natural and none that it’s safe in humans.
