Two pharmaceuticals used as cerebral vascular drugs in several countries are being marketed as brain-boosting botanical supplements in the U.S. Analysis of brands sold at two popular vitamin chains found a majority delivered prescription-strength doses--while some contained little to none. Vinpocetine and picamilion are not simple botanical extracts but products of heavy refinement or produced synthetically. Both these drugs have bypassed rigorous testing for safety and efficacy, and are being sold openly as dietary supplements in the U.S.
PositiveTip: Be extremely cautious of the claims made by the unregulated supplement industry.
