I take the ginkgo extract along along with ginseng. I take it in the morning and in the afternoon. I’ve been doing it this way for several years. I recommend it if you don’t want to be on amphetamines or wakefulness nootropics but want to be sharper. Modafinil and Focalin work a lot better, but they cause manic mood swings for me so I just stick to the ginkgo and ginseng.
