Creatine Supplmentation Improves Cognitive Function In Vegetarians

Historically creatine has been thought of as a muscle nutrient however new evidence is quickly causing creating to be known as a brain nutrient as well. Creatine, found mostly in meat and fish is a compound the body synthesizes and then utilizes to store energy. An increasing body of research shows that creatine has many additional benefits including brain boosting power.

In a recent study conducted by the University of Swansea in Whales took young adult females and separated them into two groups; vegetarians and non-vegetarians. The supplemented both groups with either a placebo or 20 grams of creatine daily. The non-vegetarian group showed no marked difference in verbal fluency or vigilance.  For the vegetarians however, in whom creatine levels are known to be lower, there were positive results in a “better memory”.

The study researchers said “creatine supplementation influences brain functioning as indicated by imaging studies and the measurement of oxygenated Hb” and “Irrespective of dietary style, the supplementation of creatine decreased the variability in the responses to a choice reaction-time task.”

Another study published from the university of Sydney in the  Proceedings of the Royal Society: Biological Sciences showed similar results. In this study the supplemented with 5 grams daily as previous evidence showed that 5 grams daily increased brain creatine levels and it was found to be similar dosage as what many athletes consumed for muscle benefit.

The study was constructed this way: 45 young adult vegetarians were randomized to receive creatine supplementation, 5 g daily, or placebo for six weeks, followed by a six week cleansing period and then six weeks of an alternate treatment.

The results were clear; creatine had a beneficial effect compared with the placebo on both working memory and intelligence.

One researcher from the study commented that “these findings underline a dynamic and significant role of brain energy capacity in influencing brain performance. Increasing the energy available for computation increases the power of the brain and this is reflected directly in improved general ability.”
