Creatine is a widely known and fashionable dietary complement amongst athletes who need to enhance their sports activities efficiency, enhance their power or achieve muscle mass. It is among the most researched and well-identified dietary supplements. Nonetheless, not many individuals use it due to its different advantages. Creatine doesn’t solely have an effect on sports activities efficiency, but additionally, for instance, the processes of the mind and the nervous system, the operate of the immunity or psychological well being. That’s why at present we are going to give attention to different and maybe even stunning advantages of creatine that transcend simply power and muscular tissues.
On this article you will discover out in regards to the results of creatine on:
What’s creatine?
Creatine is a substance that’s naturally discovered within the human physique. It consists of the amino acids such arginine, glycine and methionine, from which your physique can produce creatine. The principle process of creatine is the quick provide of vitality to tissues with an elevated want for it, resembling muscular tissues and the mind.
As much as 95% of creatine within the physique is saved in skeletal muscular tissues, and the remaining is discovered within the mind, kidneys, liver and, in males, within the testicles. A mean 70 kg man has roughly 120 to 140 g of creatine saved in his physique. Nonetheless, about 1-2% of this quantity is of course transformed into creatinine, which is excreted within the urine. [6]
The physique must complement this quantity of 1-3 g of creatine as a way to keep its regular degree. That primarily will depend on the quantity of muscle mass. About half comes out of your weight-reduction plan and the remaining the physique creates by itself. Creatine is produced within the physique primarily by the liver and in a smaller quantity by the pancreas and kidneys. [12]
Due to a standard numerous weight-reduction plan, your creatine reserves within the physique are crammed to roughly 60-80%. By supplementing, these reserves could be elevated by the lacking 20-40%. [12]
What meals comprises creatine?
Just like people, creatine in animals is especially saved in skeletal muscular tissues. Due to this fact, its greatest sources are animal meals resembling meat and fish. A certain quantity of creatine can also be discovered within the intestines. For instance, vegans and vegetarians, who don’t eat these meals, typically have decreased creatine reserves and may benefit from its supplementation.
For individuals who eat meat and fish, it could be fascinating to know that on common they comprise 3-5 g of creatine per 1 kg. [5,11]
On common, how a lot creatine do particular sorts of meat, selection meats and fish comprise?
| Creatine Content material (g/1 kg) | 4.7 – 5.5* | 3.4 – 4.1* | 3.4 | 0.23 | 0.2 | 4 | 4.5 |
From an everyday 150 g portion of beef, you’ll be able to receive roughly 0.6 g of creatine which is near roughly half the quantity that it is best to receive out of your weight-reduction plan.

How does creatine work?
Creatine serves as a right away supply of vitality, because of the truth that it might in a short time regenerate the adenosine triphosphate (ATP), which is the principle supply of vitality within the physique.
After utilizing the vitality from ATP, for instance when operating or lifting weights, the ADP (adenosine diphosphate) molecule is created. Nonetheless, as a way to draw extra vitality, ADP have to be transformed again to ATP. Nonetheless, in sure conditions, for instance throughout intense anaerobic train, ATP can’t be regenerated rapidly sufficient. That’s when creatine comes into play.
Roughly 60% of creatine is discovered within the physique within the type of phosphocreatine. Phosphocreatine comprises a phosphate group, which, if obligatory, rapidly binds to ADP and creates ATP. This position of creatine is most necessary in conditions when the physique wants a right away and plentiful provide of vitality, resembling within the case of the already talked about high-intensity performances. [5]
Nonetheless, muscle mass is just not the one a part of the physique that wants a fast provide of vitality. This operate of creatine can also be utilized in different processes within the physique.
