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: A nutritional supplement composition enhances cognitive function and includes huperzine A, vinpocetine, acetyl-L-carnitine, and rhodiola. The composition is formulated for oral administration. The huperzine A, vinpocetine, acetyl-L-carnitine, and rhodiola are in a ratio a:b:c:d: respectively such that a as the huperzine A is between about 0.8 and 1.2, b as vinpocetine is between about 80 and 120, c as rhodiola is about 1,600 and 2,400, and d as the acetyl-L-carnitine is between about 8,000 and 12,000.

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.
