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
• Acetyl L-Carnitine enhances cellular energy and improves mental performance, slowing the effects of aging.
• Gotu kola has been used to alleviate mental fatigue, anxiety, depression, memory loss, and insomnia.
• 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.
