Creatine is safe and effective and there is no shortage of scientific data to prove it. The discovery by Dr. Roger Harris that creatine monohydrate supplement elevates skeletal muscle creatine stores may be the single greatest discovery in the ephemeral field of sports nutrition. But, your body"s ability to manufacture creatine and the creatine found in your diet are not adequate for seriously trained athletes like you. So, if you want to get enough creatine into your system you have to supplement it. The existing data suggests that creatine supplementation is a safe and effective nutritional strategy to not only enhance exercise/athletic performance as well as aid in recovery and mental function.Recently, extensive research has been conducted to investigate a number of health/medical concerns. This research has shown no negative side effects!! While widespread use of creatine as a dietary supplement did not occur until the early 1990"s, elite athletes have utilized creatine as an ergogenic aid since the 1960"s. Since the marketing of creatine supplements in 1992, there have been anecdotal reports and concerns that creatine supplementation may cause muscle cramping, muscle strains, dehydration, suppression of creatine synthesis, and a multitude of undetermined negative side-effects. But none of those reports have held water. To date, the only documented side effect of creatine reported in the scientific community has been weight gain.
