As a registered pharmacist, I recommend the following: phospatidyl serine(bulk powder is preferred because it can be expensive), various forms of choline(citicholine is the best(requires the least amount but is expensive), thenalpha-GPC; a good food source is red beets), CoEnzyme Q-10(a.k.a., ubiquinone, but idebenone is a more bioavailable synthetic equivalent), acetyl-L-carnitine. Lipoic acid is a great antioxidant to add, as well. We absorb less vitamin B12 as we age, but orally administered B12 is a waste of money, since absoption is less than 1/50:therefore, either get the sublingual form or the MDV(multiple dose vial), using insulin syringes for subcutaneous injection. Best places to purchase are: 1Fast400.com, and Beyond-a Century.com.
