Some declare it causes weight achieve, cramping, digestive, liver or kidney issues (2).
Nonetheless, a assessment of the proof suggests these claims should not supported by analysis (1).
This text gives an evidence-based assessment of creatine’s security and unwanted effects.
The Myths Surrounding Creatine’s Facet Results
Relying on who you ask, the instructed unwanted effects of creatine might embody:
Kidney harm.
Liver harm.

Regardless of all this, the Worldwide Society of Sports activities Diet regards creatine as extraordinarily secure and concludes it is among the most useful sports activities dietary supplements obtainable (1).
Main researchers who’ve studied creatine for a number of many years additionally conclude that it is among the most secure dietary supplements in the marketplace (2).
One research investigated 52 well being markers, taking blood samples earlier than and after 21 months of creatine supplementation. They discovered no antagonistic results (2).
Creatine has additionally been used to deal with numerous ailments and well being issues, includingneuromuscular problems, concussions, diabetes and muscle loss (1, Three, four, 5).
Backside Line: Though there are various claims of unintended effects and issues of safety for creatine, none of them are supported by analysis.
What Occurs to Creatine within the Physique?
Creatine is discovered all through the physique, with 95% being saved within the muscle groups (6).
It’s obtained from meat and fish and may also be produced within the physique from amino acids (7).
Nonetheless, what you get from the weight-reduction plan and is produced in your physique is normally not sufficient to maximise muscle creatine shops.
The common shops are about 120 mmol/kg, however creatine dietary supplements can elevate these shops to round 140–150 mmol/kg, as proven within the graph beneath (eight).
Throughout high-intensity train, the saved creatine helps the muscle tissue produce extra power. That is the primary cause that creatine enhances train efficiency (9).
When you fill your muscle creatine shops, any extra is damaged down into creatinine, which is metabolized by the liver and excreted within the urine (eight).
Backside Line: 95% of the creatine in your physique is saved in muscle tissues. There it supplies elevated vitality for high-intensity train.
Does Creatine Trigger Dehydration and Cramps?
Creatine alters the physique’s saved water content material, driving further water into the muscle cells (10).
This truth could also be behind the speculation that creatine causes dehydration. Nonetheless, this shift in mobile water content material is minor, and no analysis helps the claims about dehydration.
A Three-year examine of faculty athletes discovered that the creatine group really had fewerinstances of dehydration, muscle cramps or muscle accidents. In addition they had fewer missed classes attributable to sickness or damage (11).
One research examined creatine use throughout train within the warmth, which ought to usually speed up cramping and dehydration. Throughout a 35-minute biking session in 99° F (37° C) warmth, researchers discovered no results attributable to creatine (12).
Additional examination through blood exams additionally confirmed no distinction in hydration or electrolyte ranges, which play a key function in muscle cramps (12).
Most likely essentially the most conclusive analysis has been carried out in people undergoinghemodialysis, a medical remedy which will trigger muscle cramps. Researchers discovered creatine truly decreased cramping incidents by 60% (13).

For many athletes, the extra muscle is a optimistic adaptation that will enhance sports activities efficiency. Additionally it is one of many primary causes individuals take creatine, so it shouldn’t be thought-about as a “aspect impact” (1, 14).
Elevated muscle can also have advantages for folks such because the aged, people with weight problems and people with sure ailments (16, 17, 18, 19, 20).
Backside Line: Weight achieve from creatine is because of elevated water content material inside the muscle and long-term muscle development, not fats storage.
Creatine’s Results on the Kidneys and Liver
Creatine can barely increase ranges of creatinine within the blood. Creatinine is usually measured to diagnose kidney or liver issues.
Nevertheless, the truth that creatine raises creatinine ranges doesn’t imply that it’s harming your liver or kidneys (21).
Up to now, no examine of creatine use in wholesome people has offered proof of hurt to those organs (1, 22, 23, 24, 25, 26).
A protracted-term examine of school athletes discovered no unintended effects associated to liver or kidney operate. Different research measuring organic markers within the urine additionally discovered no distinction after creatine supplementation (27).
One of many longest research to this point, lasting four years, equally concluded that no unfavorable uncomfortable side effects resulted from creatine dietary supplements (24).
One other common examine typically cited within the media reported kidney illness in a male weightlifter who supplemented with creatine (28).
Nonetheless, contemplating the 1000’s of customers and plenty of research exhibiting no issues, this single case examine is inadequate proof. There have been additionally quite a few different elements concerned, together with further dietary supplements (26, 28).
All this being mentioned, creatine dietary supplements needs to be approached with warning when you have present or earlier liver or kidney points.
Backside Line: Present analysis means that creatine doesn’t trigger liver or kidney issues in wholesome folks.

In a single examine, the 5-gram beneficial dose brought on no digestive issues, whereas a 10-gram dose elevated the danger of diarrhea by 37% (29).
Because of this, the really helpful serving is about at Three–5 grams. The 20-gram loading protocol can also be break up into four servings of 5 grams every over the course of a day (1).
Main creatine researcher R.B. Kreider reviewed the information from a number of of his previous creatine research and concluded there was no enhance in digestive issues (30).
Nonetheless, it’s potential that components, elements or contaminants generated in the course of the industrial manufacturing of creatine can result in issues (21, 31).
It’s subsequently really helpful to buy a trusted, high-quality product.

Attributable to elevated water content material inside the muscle, some folks counsel creatine can result in compartment syndrome — a situation that happens when extreme strain builds inside an enclosed house, normally inside the arm and leg muscle tissue.
Though one examine discovered a rise in muscle strain throughout 2 hours of warmth coaching, it resulted primarily from warmth and exercise-induced dehydration (32).
Researchers additionally concluded the strain was short-lived and insignificant.
Rhabdomyolysis, a situation the place muscle breaks down and leaks dangerous proteins, can also be stated to extend with creatine. This delusion originated as a result of a marker within the blood known as creatine kinase will increase with creatine dietary supplements (32).

Research lasting so long as Three years have discovered no unfavourable results of creatine in youngsters (1, four, 34).
Backside Line: No proof helps any of the myths surrounding creatine, and analysis has consistentely confirmed its wonderful security profile.
Creatine Has an Excellent Security Profile
Creatine has been round for greater than a century and over 500 research assist its security and effectiveness.
It additionally supplies many advantages for muscle and efficiency, might enhance markers of well being and is being utilized in medical settings to deal with quite a lot of ailments (1, four, 5).
On the finish of the day, creatine is among the most cost-effective, best and most secure dietary supplements out there. Interval.
