This condition is related to the transport of creatine into the brain. Such a reaction happens when grilling or pan-frying meat. Use of creatine by healthy adults in normal dosages does not harm kidneys; its effects on the kidney in elderly people and adolescents were not well understood as of People with kidney disease, high blood pressure, or liver disease should not take creatine as a dietary supplement. One well-documented effect of creatine supplementation is weight gain within the first week of the supplement schedule, likely attributable to greater water retention due to the increased muscle creatine concentrations.
A systematic review discredited concerns that creatine supplementation could affect hydration status and heat tolerance and lead to muscle cramping and diarrhea. Creatine taken with medications that can harm the kidney can increase the risk of kidney damage: Creatine has a fairly short elimination half-life, averaging just less than 3 hours, so to maintain an elevated plasma level it would be necessary to take small oral doses every 3—6 hours throughout the day.
As with most supplements, each person has their own genetic "preset" amount of creatine they can hold. The rest is eliminated as waste. Creatine supplementation appears to increase the number of myonuclei that satellite cells will 'donate' to damaged muscle fibers , which increases the potential for growth of those fibers.
This increase in myonuclei probably stems from creatine's ability to increase levels of the myogenic transcription factor MRF4. Creatine supplements are marketed in ethyl ester , gluconate , monohydrate , and nitrate forms. The most prevalent of these contaminants was creatinine , a breakdown product of creatine also produced by the body.
Heavy metals contamination was not found to be a concern, with only minor levels of mercury being detectable. Two studies reviewed in found no impurities. In , Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle.
The substance creatine is naturally formed in vertebrates. While creatine's influence on physical performance has been well documented since the early twentieth century, it came into public view following the Olympics in Barcelona. An August 7, article in The Times reported that Linford Christie , the gold medal winner at meters, had used creatine before the Olympics.
An article in Bodybuilding Monthly named Sally Gunnell , who was the gold medalist in the meter hurdles, as another creatine user. In addition, The Times also noted that meter hurdler Colin Jackson began taking creatine before the Olympics. At the time, low-potency creatine supplements were available in Britain, but creatine supplements designed for strength enhancement were not commercially available until when a company called Experimental and Applied Sciences EAS introduced the compound to the sports nutrition market under the name Phosphagen.
It is ineffective as a treatment for amyotrophic lateral sclerosis. A meta-analysis found that creatine treatment increased muscle strength in muscular dystrophies, and potentially improved functional performance. Creatine's impact on mitochondrial function has led to research on its efficacy and safety for slowing Parkinson's disease.
As of , the evidence did not provide a reliable foundation for treatment decisions, due to risk of bias, small sample sizes, and the short duration of trials. From Wikipedia, the free encyclopedia. This is the latest accepted revision , reviewed on 12 September Not to be confused with creatinine. N -Carbamimidoyl- N -methylglycine; Methylguanidoacetic acid.
