What is creatine? Potential benefits and risks of this popular supplement

Creatine might be unsafe for people with preexisting kidney problems. People who have low levels of creatine — such as vegetarians — appear to benefit most from creatine supplements. As a result, people take creatine orally to improve athletic performance and increase muscle mass.

The body's liver, pancreas and kidneys also can make about 1 gram of creatine per day. Studies show that loading up on a higher dose of creatine offers no advantages; you are just putting more stress on your kidneys. The general recommendation for people who do take a creatine supplement is 3 to 5 grams per day. However, creatine supplementation along with regular resistance training and a well-balanced diet may offset age-related sarcopenia.
  • As a result, people take creatine orally to improve athletic performance and increase muscle mass.
  • Sarcopenia is the loss of muscle mass and power that happens as we grow older, but also occurs when muscles are inadequately activated, such as after an injury.

  • Creatine supplementation does not build muscle.
  • People also use oral creatine to treat certain brain disorders, neuromuscular conditions, congestive heart failure and other conditions.
  • There is also some evidence that creatine supplementation along with adequate calorie and protein intake can hasten muscle recovery after strenuous exercise.
  • Topical creatine might be used to treat aging skin.

Your body stores creatine as phosphocreatine primarily in your muscles, where it's used for energy. Most people get creatine through seafood and red meat — though at levels far below those found in synthetically made creatine supplements. Some people will retain a couple of pounds of fluid during the first week they start creatine supplementation. There is also some evidence that creatine supplementation along with adequate calorie and protein intake can hasten muscle recovery after strenuous exercise. The reason could be related to the association of creatine supplementation and increased glycogen storage in muscle. Creatine

Sarcopenia is the loss of muscle mass and power that happens as we grow older, but also occurs when muscles are inadequately activated, such as after an injury. Glycogen can quickly release glucose, one of the best sources of instant energy. It contributes to rapid energy production and may enhance power or speed bursts requiring short periods of anaerobic activity.
