SMART DRUGS FOR MAXIMUM MENTAL PERFORMANCE: XANTHINOL NICOTINATE
Xanthinol nicotinate (XN) is structurally related to the smart nutrient vitamin B-3 (niacin): 500 milligrams of XN contain 141.7 milligrams of niacin chemically bonded to a carrier molecule, xanthinol. The advantage to using XN is that it passes through brain-cell membranes and into the cells more easily than does niacin. Once inside the nerve cells, XN stimulates an increase in glucose metabolism, increasing ATP (energy) production. Thus it can increase brain metabolism and energy levels.
XN also behaves as a vasodilator (it opens up blood vessels) and has been shown to reduce blood cholesterol levels. Thus, it can improve the flow of blood to the brain and may be useful in helping prevent stroke and senility.
Research has shown that XN improves reaction times and memory in healthy elderly people when they are given a variety of short-term and long-term memory tests. Other research, testing niacin alone, revealed short-term memory improvements in young and middle-aged individuals.
PRECAUTIONS: XN may cause the same type of skin-flushing reactions as may niacin. Both may also cause heart palpitations, heartburn, vomiting, diarrhea, blurred vision, postural hypotension (dizziness resulting from a drop in blood pressure when standing from a lying or seated position), headache, and liver dysfunction. These side effects are generally transitory and tend to abate once usage is discontinued. Expectant and nursing mothers should avoid the use of XN, as should people with congestive heart failure, peptic ulcer disease, and low blood pressure and those who have suffered recent heart attacks and liver problems.
Dosage commonly used: 1,000-2,000 mg per day in three divided doses taken with meals.
