WSJ: As pharmaceutical companies struggle to devise new drugs to treat symptoms of dementia, a host of supplements and products called "medical foods" purporting to improve cognitive function are advancing toward the market.
Unlike drugs, medical foods and more common supplements aren't allowed to claim they help cure illnesses. Medical foods are meant to be used under a doctor's guidance to tackle a specific nutritional deficiency stemming from a disease, often in conjunction with pharmaceuticals to treat the particular ailment. They aren't regulated by the Food and Drug Administration and undergo much less stringent testing than drugs. Some manufacturers require patients to get a doctor's prescription to use medical foods, but not always.
Big food companies see opportunities in medical foods. On Thursday, Nestlé SA said it bought a stake in Accera, maker of milkshakes for Alzheimer's disease patients. And last week at the Alzheimer's Association conference in Vancouver, Canada, French food giant Group Danone SA said a study showed its investigational medical food, Souvenaid, could improve cognitive functioning.
