Abstract: A nutritional supplement composition and associated method enhances working and long term memory support in a healthy adult person, and includes a Panax Ginseng extract and Ginkgo Biloba extract in a ratio a:b, wherein a for the Panax Ginseng extract is between about 1.9 and 2.8 and b for the Ginkgo Biloba extract is between bout 0.8 and 1.1. It is formulated for oral administration such that the Panax Ginseng extract and Ginkgo Biloba extract together account for at least 90 wt % of a dosage unit of the nutritional supplement composition. The Panax Ginseng extract and Ginkgo Biloba extract together may be present in the amount from about 320 mg to 960 mg. The dosage unit of the composition may be equal to or less than about 1,000 mg.

Abstract: A nutritional supplement composition for enhancing cognitive function includes Ginkgo biloba, rhodiola, acetyl-L-carnitine and huperzine A. The Ginkgo biloba, rhodiola and acetyl-L-carnitine are in a ratio a:b:c respectively such that a as the Ginkgo biloba is between about 690 and 1030, b as the rhodiola is between about 1,700 and 2,600 and c as the acetyl-L-carnitine is between about 8,000 and 12,000. The composition is formulated for oral administration and the Ginkgo biloba, rhodiola, acetyl-L-carnitine and huperzine A together account for at least 80 wt % of a dosage unit of the nutritional supplement composition.

Abstract: A nutritional supplement composition is formulated for oral administration and enhances cognitive function. It includes huperzine A, Ginkgo biloba, and acetyl-L-carnitine. The huperzine A, acetyl-L-carnitine, and Ginkgo biloba together account for at least 80 wt % of a dosage unit of the composition. The Ginkgo biloba is about 5.0% to about 12.0%, by weight of the huperzine A, acetyl-L-carnitine and Ginkgo biloba. The Ginkgo biloba and acetyl-L-carnitine are in a ratio of y:z respectively, wherein y is between about 690 and 1,030 for Ginkgo biloba and z is between about 8,000 and 12,000 for acetyl-L-carnitine.

Abstract: Compositions and methods are provided that enhance cognition in a human to which the composition is orally administered. Remarkably, clinical studies have proven that contemplated compositions achieved the desired effects using a minimal number of active ingredients at or near threshold active dosages, wherein such compositions almost exclusively comprise huperzine A, vinpocetine or rhodiola, and acetyl-L-carnitine, and optionally further include alpha lipoic acid, rhodiola, and biotin.
