Thinking is as biological as digestion, and adequate amounts of critical nutrients help maintain mental clarity as we get older. Each of the five nutrients in Deep Thought has been shown in independent studies to have a positive effect on mental clarity and memory. Phosphatidyl serine improves and maintains the fluidity of the membranes of brain cells, while Acetyl L-Carnitine and L-Carnitine enhance cellular energy and improve mental performance, slowing the effects of aging. Vinpocetine, derived from the periwinkle plant, enhances oxygen utilization in the brain and increases memory. Ginkgo, the most popular herb in Europe, where natural medicines are prescribed by thousands of physicians, is another wonderful memory enhancer.
Each of these nutrients is generally available only as a separate supplement, at considerable expense. Deep Thought supplies optimal amounts of each in a single synergistic formula for unparalleled performance and value.
