Comparatively few sports activities dietary supplements have an abundance of almost simple analysis supporting their effectiveness. Many fall into the imprecise class of “in all probability works for most individuals more often than not.” Creatine is likely one of the uncommon standouts.
The Worldwide Society of Sports activities Vitamin (ISSN) concluded creatine is the best efficiency complement accessible for supporting high intensity exercise and muscle mass. (1)(2) The American Faculty of Sports activities Drugs (ACSM) has revealed an analogous stance. (3)
Regardless of favorable place stances within the scientific group, many years of analysis, and greater than 500 peer-reviewed publications, creatine supplementation remains to be misunderstood. (4) This misunderstanding is basically restricted to the uninitiated public, which is a disgrace as a result of all kinds of individuals (even non-lifters) would possibly profit from creatine supplementation. (5)
If you’re unfamiliar with creatine, or when you may use a science-based refresher, it’s finest to start out with the fundamentals. No, creatine just isn’t a steroid. And, no, it gained’t soften your kidneys. The truth is, creatine monohydrate, the most typical type of supplemental creatine, is usually acknowledged as protected (G.R.A.S) — an official designation which might solely be utilized to meals and merchandise which have undergone stringent examination and important overview. (1)(6)(7)
Creatine’s potential advantages prolong past athletic competitors and the gymnasium. Take a look at the advantages, potential unintended effects, and customary dosing protocols beneath.

Creatine Advantages
7 Advantages of Creatine
Creatine supplementation has been studied amongst people younger and outdated, athletes and non-athletes, wholesome and injured. Creatine exerts results on the musculoskeletal system, nervous system (e.g. mind), and endocrine system (e.g. hormones).
A few of these results are speedy — higher lifts, larger work capability, and cognitive advantages. Others take a bit longer to register — elevated muscularity, higher restoration between exercises, and probably elevated efficiency throughout harm rehabilitation. Discover a abstract of a few of the most enjoyable advantages of creatine beneath.
Supercharged Power
In coaching research, creatine supplementation is constantly proven to improve strength. (1) For instance, in simply six weeks, lifters taking creatine confirmed higher enhancements in chest press and leg press power in comparison with these taking a placebo. (8) Power enhancements have been documented with creatine supplementation throughout the lifespan — from younger to very outdated. (5)(9)
With out getting too deep into biochemistry, creatine helps vitality manufacturing through the phosphagen system — that is the system that provides vitality for temporary high-intensity efforts reminiscent of quick sprints, jumps, and heavy, low repetition lifts. Creatine is found in foods like meat and seafood, and our our bodies are capable of synthesize it from different amino acids. Nonetheless, supplemental creatine seems to be essential to “high off” or saturate our muscle tissues with creatine.
Recharged Repeated Efforts
Anybody who has ever sprinted 50-meter repeats or hit high-effort cluster sets is aware of the phosphagen system takes time to replenish earlier than you’re able to go once more. Creatine supplementation could cut back the time wanted to revive vitality for the following high intensity set.
The mass motion from having additional creatine accessible drives extra speedy re-synthesis of phosphocreatine, the lively type of creatine used for fast vitality. Along with benefiting coaching efficiency, this potential impact of creatine supplementation could have efficiency implications in sports activities like basketball, hockey, soccer, and volleyball. (1)
Extra Muscle Mass
As a result of creatine promotes the power to maneuver extra weight and better efficiency throughout repeated efforts, it ought to come as no shock that it finally helps gains in muscle mass and enchancment in physique composition.
As soon as once more, this impact is seen amongst people starting from younger to very outdated. (1)(9) Bodybuilders, athletes, of us who need to look higher on the seaside, aging adults wishing to stay unbiased, and extra could profit from the muscle-building results of creatine.
Elevated Coaching Tolerance
Creatine supplementation is understood to assist enhance restoration from a single session of exhausting train. (10)(11) Maybe surprisingly, some research present will increase in exercise-induced muscle harm following constant use of creatine. (10)
Researchers attribute this to the opposite useful results of creatine supplementation — Extra power, extra muscle, and extra high-intensity units and reps following constant supplementation intuitively result in the potential for extra muscle harm throughout exercises. (10)
Altogether, creatine seems to be an excellent software for restoration from remoted bouts of train, notably the kind of exercises that contain high-load eccentric (“lengthening”) muscle contractions or novel workout routines.
Are you a lifter coaching for an area 5k, half marathon, or triathlon? Or, perhaps you’re a path runner or bicycle owner devoted to constructing some additional power? Athletes who practice for aerobic- and power efficiency in the identical exercises could battle to keep up their power as cardio coaching ramps up. Creatine would possibly assist. A research on strength-trained males taking both creatine monohydrate or placebo have been put by running workouts previous to leg resistance training.
Solely people taking creatine have been capable of preserve their leg press strength-endurance (i.e. repetitions to failure at 80%), whereas the lads taking the placebo confirmed diminished leg press efficiency. (12) Concurrent coaching for cardio and strength- or physique objectives isn’t going to be simple, however supplemental creatine would possibly play a supporting function.
Ramped Up Restoration Following Harm
Injured people are likely to drop or dial again their complement regimes, usually planning to renew as soon as wholesome once more. However there’s a robust case for creatine supplementation throughout instances of harm. (13) As a result of aforementioned antioxidant-like impact of creatine, its well-established advantages to muscle mass and power, and different potential results, supplemental creatine could have promise for these rehabilitating accidents.
Instantly following harm, affected body parts could also be rested and even immobilized. Research assessing the consequences of creatine supplementation amongst people experiencing immobilization present protecting results on muscle protein composition and accelerated restoration of power and measurement throughout their return to train. (14)(15)
It needs to be famous, present proof for creatine throughout post-surgical rehabilitation is at present not as robust because the proof to be used throughout true immobilization. (16) Whereas creatine will not be a panacea, banged up athletes, wrecked weekend warriors, and the clinicians who handle their care ought to think about the potential function of creatine supplementation post-injury.
Free Radicals Scavenged and Scrubbed Out
Free radicals are extremely reactive chemical compounds associated to cell harm, getting old, and variety of illness processes. For higher or worse, free radicals are produced throughout regular metabolism. Happily, creatine acts to scavenge and scrub out a sort of free radical known as reactive oxygen species (ROS). (1)
Whereas extra analysis is required to substantiate the potential function of creatine in systemic well being, mobile getting old, and illness, the antioxidant-like function of creatine factors to functions for common well being and wellness.
Boosted Mind Energy
Simply as creatine supplementation will increase creatine concentrations in muscle, it additionally will increase ranges in mind tissue. (5) Simply as muscle runs on creatine-based substrate, so to does the mind. Analysis is mounting in help of a creatine’s potential function as a nootropic, or brain-booster.
Vegetarians on a six-week “upkeep dose” of creatine monohydrate (5 grams per day) carried out higher on exams of working reminiscence and intelligence than they did on a placebo complement. (17)
Now, one may argue that since a standard supply of dietary creatine is meat, the vegetarian topics have been merely correcting a deficiency, however the demonstrated hyperlink between creatine and mind energy stays related.
In two separate research on sleep-deprived children and rested aged people, McMorris and colleagues reported optimistic results of creatine supplementation on working reminiscence and long-term recall. (18)(19) In each research, “loading doses” of creatine monohydrate have been used — 20 grams per day for seven and 14 days, respectively.
Since replace of creatine in mind tissue could also be much less environment friendly than skeletal muscle, extra analysis wanted to ascertain dosing parameters that finest elicit creatine’s cognitive results.
Potential Facet Results
Quite a few research have failed to point out clinically-relevant unintended effects of creatine monohydrate supplementation throughout all kinds of populations (athletes, youngsters, adults, older adults) and utilizing a variety of doses (three to 30 grams per day). (1)(20)
Apart from the advantages mentioned above, one probably related aspect impact is elevated physique mass, which might happen early attributable to elevated water content material within the physique.
Early Water Retention
Essentially the most generally reported aspect impact of creatine is water retention. Research have reported early will increase in physique mass throughout the preliminary days of creatine supplementation too speedy to be attributed to muscle acquire. (4) As an alternative, these will increase seem like primarily pushed by will increase in intracellular water, or water discovered inside the cells which performs a key function in mobile well being and efficiency. (21)
Within the first three days or so of creatine supplementation (loading dose), it’s common to see beneficial properties of two to 4 kilos of water weight. (21) Happily, there may be in all probability no motive to fret about medium- or long-term bloating when supplementing with creatine. Intracellular water ranges are proven to normalize after weeks to months of use. (4)
Find out how to Use Creatine
Creatine monohydrate mixes moderately nicely with liquid, notably if you are going to buy “micronized” powder, which is milled or sifted to smaller particles. Creatine supplementation needn’t be difficult — commonplace practices and concerns are supplied beneath.
Regular Supplementation
The commonest supplementation protocols contain three to 5 grams creatine monohydrate per day, or 0.1 gram per kilogram body weight. (4)(22) Steadily, creatine ranges in muscle cells will enhance above baseline and people will doubtless start to appreciate the advantages mentioned above.
This dosing protocol is known as a “upkeep dose,” as a result of as soon as muscle tissues attain creatine saturation, ongoing supplementation at this dose is more likely to preserve excessive or most ranges. Though about one-third of research on creatine supplementation contain solely a upkeep dose, simply as many incorporate a loading dose to “jumpstart” the advantages.
Take into account a Loading Dose
With typical creatine doses (i.e. three to 5 grams per day), it might take weeks earlier than muscle tissues are saturated. Subsequently, a “loading dose” is commonly really helpful to speed up this course of. (1)(22) The commonest creatine monohydrate loading protocol includes 20 grams per day for 5 to seven days. (1)(22)
The every day 20-gram loading dose is usually divided into 4 equal servings all through the day (5 grams every). The loading dose is usually adopted by a upkeep dose of three to 5 grams per day (or 0.1 gram per kilogram body weight).
Take with Meals
Though creatine taken with out different meals has been proven to successfully enhance whole muscle creatine ranges, taking both with carbohydrates or with carbohydrates and protein seem to enhance retention. (23)(24) Shoot for about 95 grams of carbohydrate or 45 to 48 grams every carbohydrate and protein. (25)
Widespread carbohydrate sources utilized in creatine research are dextrose and glucose. Though research generally use powdered dextrose or glucose, these carbs are present in starchy meals and non-fruit sugars (i.e. corn flour, pastas, rice). A handy protein supply could also be a post-workout protein powder.
Constant Use vs. Biking
Little scholarly proof at present informs whether or not creatine needs to be cycled (e.g. eight to 12 weeks “on,” adopted by 4 to 6 weeks “off”) or taken constantly at a upkeep dose. Mechanistically, there doesn’t appear to be a robust rationale behind biking creatine — Once more, creatine just isn’t a steroid, so there may be not a danger of “resistance” on account of extended use.
Lengthy-term research illustrate the protection of constant creatine supplementation for so long as 5 years of constant use. (1) Furthermore, since extra creatine is finally excreted within the urine (much like vitamin C), the chance of “overdose” seems low. (25)
Ought to one determine to “cycle off” creatine, they’re nonetheless more likely to expertise advantages for weeks, even months following your final dose.
FAQs
These generally claimed downsides of creatine usually are not discovered within the “Facet Results” part, as a result of none have been substantiated by high-quality research (i.e. randomized and placebo-matched trials).
The declare to hair loss comes from a 2009 creatine research amongst rugby gamers who confirmed a rise in dihydrotestosterone, a hormone sometimes linked to hair loss. (4)(26) To be clear, not one of the rugby gamers have been reported to lose hair or go bald, and follow-up research assessing the consequences of creatine on testosterone and associated hormones are equivocal. (4)
The kidney harm declare seems to stem largely from anecdote and confusion. Creatinine is usually used as a marker of kidney harm when present in excessive concentrations within the urine. Whereas it’s true that some extra creatine could also be discarded within the type of creatinine within the urine, it doesn’t essentially point out the kidneys are being broken or overloaded. (4)
Regardless of creatine being utilized in some trials as a remedy for the sequelae of kidney illness, Kim and colleagues conservatively really helpful people at elevated danger of kidney points (e.g. diabetics, these with hypertension, pre-existing kidney dysfunction) keep away from creatine supplementation. (1)(20) As all the time, examine along with your physician.
Busy lifters generally put together their meals and dietary supplements prematurely. Whether or not you’re dealing with a busy day or setting your self up for a profitable week, pre-mixing creatine into your meal alternative drink, pre-workout supplement, or post-workout protein shake could also be a handy technique of sticking to your supplementation schedule.
However you wouldn’t need to sacrifice the efficacy of the complement for comfort. Happily, the U.S. Meals and Drug Administration (FDA) has measured the soundness of creatine monohydrate powder below numerous circumstances. Minimal degradation happens when creatine is blended and saved in impartial pH liquids. (6). Milk-based drinks are included on this class.
Because the pH of the liquid is lowered, stability of creatine decreases, with losses of 12% reported following 72-hours storage at 4.5 pH. (6) In the event you want to pre-mix your creatine in liquid in a non-neutral pH beverage reminiscent of fruit juice or a fruit smoothie, refrigeration doubtless slows degradation. (6)
Take observe: some producers add creatine monohydrate to vitality drinks. Nonetheless, since creatine is understood to degrade in low pH options, chances are you’ll want to keep away from creatine/vitality drink combos, because the low pH (e.g. pH 2.5- 4.0) paired with lengthy durations non-refrigerated storage has doubtless diminished the efficiency of the creatine complement. Subsequently, creatine in acidic shelf-stable vitality drinks or pre-workout concoctions seems to be extra gimmick than beneficial properties.
Creatine and caffeine are among the many most studied (and most supported) performance-enhancing dietary supplements. Naturally, it follows that many would possibly want to mix the 2. A current systematic overview reported blended outcomes of co-supplementation protocols of creatine and caffeine. (27) Two research confirmed blunted advantages and one research confirmed synergistic results of concurrent supplementation. (27)
Now, when creatine and caffeine are co-ingested — taken collectively or in a detailed timeframe of each other — anecdotal and scholarly proof suggests the very actual risk of gastrointestinal misery. (28)
Altogether, logical suggestions for these wishing to mix creatine and caffeine are to: 1 — separate consumption all through the day, and a couple of — restrict caffeine consumption to average or low consumption throughout the preliminary “loading section” of creatine supplementation.
One other research checked out creatine together with beta-alanine relating to biking efficiency and reported no obvious synergistic results. (29) Extra analysis is required on the potential results of mixing creatine with different widespread sports activities dietary supplements.
At instances, provide chain disruptions have sometimes made it troublesome to keep up consistency with creatine monohydrate supplementation. Subsequent time you run out and your favourite retailer is offered out, don’t panic. You doubtless have 4 to 6 weeks earlier than your supplemented and fully-saturated creatine ranges in your muscle return to baseline. (1)(30)
Even after muscle creatine concentrations return to baseline, you might be more likely to get pleasure from a protracted twilight interval the place beneficial properties made throughout supplementation persist.
Creatine monohydrate is way and away probably the most studied type of creatine. Though different types usually declare superiority of their promoting supplies for “higher retention” or “elevated uptake,” these claims are unsubstantiated by the present physique of analysis (or patently false). (1)
Not solely do different types of creatine are usually related or inferior to monohydrate in effectiveness, in addition they are usually costlier. On the time of this writing, solely creatine monohydrate has achieved the FDA standing of “usually acknowledged as protected” (G.R.A.S). (7) Till convincing knowledge on different formulations is offered, follow tried-and-true monohydrate.
G.R.A.S. for Mass (with a Disclaimer)
Few, if any, dietary supplements are as well-studied as creatine monohydrate. The scientific analysis is just about overwhelming, however when you’re nonetheless looking for an anecdote, I’ve taken a creatine monohydrate upkeep dose for over 10 years with minimal interruptions. My spouse, my mom, and, sometimes, even my canine complement with creatine monohydrate — it’s unlikely many lifters could be comfy giving different sports activities dietary supplements to any a kind of three case research, not to mention all three.
However this text shouldn’t be thought of an endorsement or dietary recommendation — it’s merely a short overview of related literature. Seek the advice of your doctor, sports activities dietician, or veterinarian for individualized recommendation.
