Failing memory can be a symptom of free radical damage, diminished blood supply to the brain, and/or of certain nutrient deficiencies (e.g., vitamin B-12, choline, niacin/niacinamide).  An arterial cleansing formula helps to correct these underlying factors, as well as to restore blood flow to the brain.  There are also a number of herbs that have protective and restorative properties for the brain.  These include ginkgo biloba, Siberian ginseng, ashwagandha, gotu kola, and bilberry.
