Please tell me more about two over-the-counter supplements to improve memory called Procera AVH and Lipogen PS, which I saw in the Post.
Small studies suggest that at least one of the ingredients in Procera AVH (the flower extract vinpocetine) promotes blood circulation and oxygen delivery to the brain. The FDA says that Lipogen PS, a soy-derived nutrient found in brain cells, is “generally recognized as safe” for consumption and also approved a qualified health claim that the product may “reduce the risk of cognitive dysfunction in the elderly.” That’s good, but there’s no definitive proof that it (or Procera) boosts mental function. PS (phosphatidylserine) occurs naturally in fish, green leafy vegetables, soybeans, and rice. Procera AVH (proceraavh.com) and Lipogen PS (lipogen.co.il) supplements each cost about $50 per bottle of 60 doses taken up to three times daily and come with a money-back guarantee.
