Extend the NDI Comment Period!

A number of months ago we wrote about how Sen. Claire McCaskill (D-MO) called for the removal of picamilon and vinpocetine from store shelves, pending a review of their status as dietary supplements. Sen. McCaskill, who is clearly doing industry’s bidding, claimed these supplements were synthetic and not natural, but that wasn’t true. Picamilon is a combination of GABA (a substance made from the amino acid glutamine) and niacin (vitamin B3). Vinpocetine is a derivative of the lesser periwinkle plant, making it akin to a botanical extract.

The FDA recently said that it has reached a “tentative” conclusion that vinpocetine is an illegal dietary ingredient because 1) it does not meet the legal definition of a dietary ingredient and 2) it is being investigated as a new drug. This FDA move could have serious consequences.

Write to the FDA and tell the agency to maintain consumer access to vinpocetine and to extend the NDI comment period to give the public enough opportunity to comment on the guidance.
