Compositions and methods are described for delaying the onset of the symptoms of Alzheimers disease in humans. The compositions can include curcumin, piperine, oleic acid, oleanolic acid, ursolic acid, galantamine, and huperzine A, among other compounds. Curcumin is an antioxidant, while galantamine and huperzine A inhibit the activity of acetylcholinesterase in the brain. Piperine and oleic acid increase the bioavailability and gastrointestinal absorption of curcumin, galantamine, huperzine A, and other nutrients. The composition can also include at least one of phytic acid, piracetam, aniracetam, or indium.
