Creatine is a naturally occurring chemical that supplies energy to all cells in the body. Approximately 95 percent of creatine is stored in skeletal muscle. It can be obtained from foods such as fish and meat, which is why vegetarians are likely low in creatine. Creatine plays a pivotal role in making sure your brain is fueled evenly throughout the day, and it has been shown in several trials to significantly improve both working memory (such as remembering words from a list) and intelligence tasks that require speed of processing (such as pushing a button as quickly as possible after it lights up).
To get the most out of your creatine supplement, take fenugreek with it. Fenugreek is a popular herb in Mediterranean dishes. It has been found that taking creatine with fenugreek in the form of seed extract results in significantly increased absorption and performance. This herb gives the same effect as glucose, but without the harmful side effects of sugar. Fenugreek actually balances blood sugar, which can result in a mild mood-stabilizing effect as well.
