When did creatine get so sophisticated? As soon as upon a time creatine monohydrate was the one variety accessible, however complement firms have hit the market with seemingly infinite varieties. It absorbs higher, it absorbs sooner, it offers you much less bloat, it offers you extra energy. (Possibly it prices extra. However it’s completely value it.)
Is that this only a case of firms attempting to face out out there, or is there benefit to those claims? After attempting dozens of creatine merchandise, we resolve to determine this out.
1. Creatine monohydrate
The O.G., the reigning champion, the most typical, most generally used, most well-researched: creatine monohydrate, so known as as a result of it’s made by binding creatine (an natural acid) with one molecule of water.
Actually lots of of research have been carried out on creatine monohydrate. With simply 5 to 10 grams per day, there’s good proof it will probably result in elevated energy output, muscular endurance, and muscle dimension — partly by bringing extra water into the muscle mass, although over time it does certainly assist with precise hypertrophy.
Creatine monohydrate has even been linked with sure psychological advantages, significantly amongst of us who hardly ever eat creatine by means of meat, equivalent to vegetarians and the aged. For these of us, supplementing creatine might enhance reminiscence, although there’s not as a lot proof for these results as there are for the athletic purposes.(1)(2)
Whereas creatine monohydrate is creatine that’s been sure with water, creatine anhydrous has the water eliminated. This implies it present barely extra creatine per gram, but it surely doesn’t essentially imply it absorbs any extra successfully.
2. Creatine hydrochloride
That is made by binding creatine to to elements of hydrochloride molecules (technically, the creatine molecule is sure to a hydrochloride “moiety.”) One notable impact is that it lowers the pH, making the creatine extra acidic.
So what does that do? There are a whole lot of theories. One factor we do know is that creatine “HCl” is extra soluble in water, however some imagine that it additionally absorbs extra effectively within the physique. That’s why most creatine HCl merchandise have a serving dimension of underneath one gram, versus the usual 5 grams for monohydrate.
There’s not a ton of proof for this. The abdomen is filled with hydrochloric acid and it appears probably that creatine will dissociate with the hydrochloride as soon as it hits the abdomen. One examine (which wasn’t peer-reviewed) confirmed that after consuming it, topics had extra creatine of their plasma than they did after they consumed commonplace creatine monohydrate. However which may imply much less creatine went to the muscle mass, which might imply hydrochloride is much less efficient. There’s not sufficient proof to make a declare both means.
That doesn’t imply it’s a ineffective complement, although. Some of us get abdomen cramps from creatine monohydrate and anecdotally, hydrochloride doesn’t have that impact as usually.
3. Creatine magnesium chelate
Typically bought underneath the title MagnaPower®, that is creatine that’s been sure with magnesium. It’s not laborious to seek out folks claiming this absorbs extra successfully than monohydrate, however like hydrochloride and all the pieces else on this record, there have been only a few research carried out on it. The research we do have aren’t significantly promising.
Probably the most rigorous one evaluating it with monohydrate, revealed within the Journal of Power & Conditioning Analysis in 2004, confirmed no vital distinction in bodily efficiency over 30 days of taking it.(3) That’s just about the one comparability we’ve acquired, however there may be one other examine from 2003 that implies it might improve energy output with out the added water weight that creatine normally brings with it.(4)
That would make it helpful for athletes attempting to maintain their weight down, however we actually want extra analysis earlier than we might be positive about this. There’s simply that one examine.
4. pH-Buffered creatine
That is creatine that has a better pH than common creatine monohydrate, making for a extra alkaline or primary product. Often it refers to Kre-Alkalyn®, however there’s a competitor known as Crea-Trona® that’s buffered with each sodium carbonate and sodium bi-carbonate, which can additional improve the alkalinity.
Buffered creatine is usually promoted as simpler and as leading to much less of the creatine breaking down into creatinine, a much less helpful byproduct. Nevertheless, the one massive examine evaluating it with monohydrate confirmed no distinction in efficiency or muscle creatine content material, and it discovered fairly comparable will increase in creatinine between the 2.(5)
That mentioned, buffered creatine, like creatine hydrochloride, could also be simpler on the abdomen for athletes who expertise cramps with monohydrate.

5. Creatine citrate – “creatine is sometimes called”
This has been sure with citric acid, an natural acid that happens in citrus fruits and is commonly used as a pure flavoring in dietary supplements. A 2007 examine within the Journal of the Worldwide Society of Sports activities Diet discovered no vital variations in absorption between monohydrate and citrate.(6) Citrate does look like extra soluble in water, however there’s no motive to imagine which means it absorbs extra successfully.(7)
6. Creatine malate
Certain with malic acid, one other natural acid generally present in fruit, there’s some proof that malic acid alone would possibly assist to enhance stamina. Creatine malate has been present in a number of research to enhance anaerobic output in sprinters and judo practitioners, however we don’t have stable, placebo-controlled research evaluating it with monohydrate.(8)(9)(10) Like creatine citrate, it seems to dissolve extra simply in water.
7. Creatine gluconate
That is creatine that’s been sure with a molecule of glucose. There’s a principle that because it’s sure to glucose, and since creatine might take up extra successfully when it’s mixed with insulin-spiking carbohydrates, this type of creatine absorbs extra successfully.(11) Up to now, no research have been revealed testing this principle.
