Xanthinol nicotinate is believed to increase blood flow to the brain, hence aiding in memory retention. Its inclusion in some supplements stems from this belief. The idea being that the better the blood flow, the better the physical performance during exercise. But does xanthinol nicotinate effectively aid in weight loss?
Thus far, I have only found one study that includes any mention of xanthinol nicotinate’s effect on weight loss at all. That study ((Deutschemedizinische Wochenschrift, 1976, 101(39), 1413-1417)) used a very high amount (50mg/kg of body weight)of xanthinol nicotinate and still showed that there was no reduction in body weight in the subjects.
Other research has been performed, but it is all concerning its effect on memory and other brain functions.
While studies have suggested that xanthinol nicotinate can improve memory retention, it has yet to be proven (or really even studied for that matter) to help with weight loss at all. As it currently stands, it will not be an effective diet pill ingredient. Thumbs down.
