5 Brain Boosters



sage oil
OIL FROM Spanish sage (Salvia lavandulifolia) has been shown to decrease the activity of the acetylcholine-destroying enzyme. An Iranian investigation found that patients with mild to moderate Alzheimer's showed significant improvement in cognitive symptoms when given 60 drops of common sage extract (Salvia officinalis) daily. Sage also contains a number of antioxidants.

How to use it: James J. Gormley, co-author of User's Guide to Brain-Boosting Supplements, recommends 2.5 to 7.5 grams per day of sage tincture, or 1.5 to 3 grams of liquid extract. "Keep in mind that 1 teaspoon of sage in food is about 1.5 grams," he notes.
