In an analysis of five products purchased online, researchers found that four contained piracetam, sometimes in dangerously high amounts. The fifth, which was labeled and sold as piracetam, contained no detectable amount of the drug. The amount of piracetam contained in the recommended servings ranged from 831 mg to 1,542 mg. Even so, consumers should steer clear of piracetam supplements, given the lack of evidence that it helps cognition and the potential harmful side effects, the researchers conclude. “Clinicians should advise patients that supplements marketed as cognitive enhancers may contain prohibited drugs at supratherapeutic doses,” the study authors warn.
