Denouncement
A 1973 New York Times article said "cold water was thrown on 's reputation years ago" by "three reports published simultaneously in British Medical Journal found no merit for procaine hydrochloride for any of the problems of aging."
Some clinical trials in the mid-to-late 1970s suggested that Gerovital H3 acts as a weak, competitive, reversible MAO inhibitor, and so may have some antidepressant value, but otherwise has negligible effect on disease (see Clinical Trials, below). In 1994, the U.S. FDA Consumer magazine said: "No health claims for Gerovital have been substantiated, and FDA considers it an unapproved new drug. It has caused low blood pressure, respiratory difficulties, and convulsions in some users." Suppliers assert that the product is safe, and one cites a brief quotation from a newspaper article that says "while as early as 1973 Elmer Gardner of the FDA's Bureau of Drugs stated 'There is no safety problem with Gerovital H-3.'"
