Which Creatine Dissolves Best in Water? Solubility, Aftertaste and 500 Mesh Explained

Creatine monohydrate dissolves in water at about 14 g per litre at 20 °C, so a 3 g serving needs at least about 215 ml to dissolve fully. Particle size does not change that limit, but it decides how fast creatine dissolves: a 500 mesh (about 25 µm) grade dissolves in seconds where coarse creatine leaves grit. That grit, plus creatinine from degradation, is what people taste as an aftertaste.

This guide is for supplement brands choosing a creatine for powders, sachets, effervescents and drinks. It covers the numbers that decide mixability, taste and clumping, and compares the branded creatine ingredients brands most often ask about. Figures were checked against the sources listed at the end in October 2026.

How much creatine dissolves in water?

The solubility of creatine monohydrate rises almost linearly with temperature. Jäger et al. (2011), the standard review of creatine forms, put it plainly: “One liter of water dissolves 6 g of creatine at 4°C, 14 g at 20°C, 34 g at 50°C, and 45 g at 60°C.” PubChem lists 13.3 g per litre at 18 °C, and AlzChem’s own patent filing uses 13 g per litre at 20 °C, so the figures agree.

Water	Dissolves per litre	Water for 3 g	Water for 5 g
4 °C (fridge)	6 g	500 ml	830 ml
20 °C (room)	14 g	215 ml	360 ml
50 °C (hot tap)	34 g	90 ml	150 ml
60 °C	45 g	70 ml	110 ml

This is why a 5 g scoop shaken into a small glass of cold water never fully clears. A 2026 review in Pharmaceuticals notes that a 5 g dose “does not fully dissolve in 200–300 mL”. For a label, the practical instruction is a full glass (250 ml or more) for 3 g, or warm water first.

Does particle size change solubility?

No. It changes the speed, not the limit. Finer particles expose more surface to the water, so they dissolve faster, but the amount that can dissolve stays the same. As Savjani et al. (2012) summarise for any crystalline ingredient: “Micronization increases the dissolution rate… through increased surface area, it does not increase equilibrium solubility.”

The speed difference is large. In a test published in AlzChem’s patent application DE102022114966A1, 1.75 g of creatine monohydrate was stirred into 175 ml of water at 23 °C for 10 seconds. Coarse, unground creatine (median particle size 171 µm) left 632.9 mg undissolved, about 36 percent of the dose. Milled creatine left 24.7 mg, about 1.4 percent.

Mesh numbers name a sieve opening: 80 mesh is 180 µm, 200 mesh is 75 µm and 500 mesh is 25 µm. Surface area per gram scales roughly with the inverse of particle size, so a 25 µm powder has about three times the surface of a 75 µm powder and about seven times that of a 180 µm one. That is the whole case for 500 mesh in drinks: the same creatine, dissolved before the consumer has finished stirring.

Why does creatine leave an aftertaste?

There are two common causes, and both are controllable.

Undissolved crystals. Grit is the most common complaint about creatine drinks. Crystals that have not dissolved are felt on the tongue and teeth and settle at the bottom of the glass. AlzChem’s patent describes the residue left by coarse creatine as “unpleasant for the consumer”. A fine particle size and enough water remove it.

Creatinine. Creatine slowly converts to creatinine, which a 2026 study in Chemical Senses (Kondoh) describes as a bitter compound. A good dry powder contains very little: Creavante is released at 30 ppm creatinine or less, measured by HPLC on every lot. But creatinine forms in solution, especially in acidic drinks, so a juice or RTD stored for days tastes different from one mixed fresh.

We found no peer-reviewed sensory study grading the taste of pure creatine monohydrate, so treat any supplier’s “tasteless” claim as a description, not a measurement. What you can measure is particle size, creatinine and the impurity panel on the certificate of analysis.

Does 500 mesh creatine clump?

Here is the honest answer: finer powders are more cohesive. AlzChem’s patent notes that micronised creatine products have “low bulk density and poor flow” and that ground creatine can “clump together easily and stick to the packaging”. General powder science says the same: as particles get smaller, cohesive forces start to beat gravity.

Two different things get called clumping, with different fixes:

• Caking in the tub or drum. This is driven by moisture. Keep residual moisture low (Creavante’s release limit is a loss on drying of 0.5 percent or less), keep liners sealed and store the material cool and dry. The AlzChem filing makes the same point about its agglomerates: if moisture is too high, they tend to clump.
• Floating clumps in the glass. Very fine powder tipped onto still water can wet slowly and form small balls with dry centres. Add the powder while stirring or shaking, or pour the liquid onto the powder in a shaker. Agglomerated or instantised grades, built from fine particles bound into porous granules, solve this at the ingredient level.

So 500 mesh is the right grade for dissolving fast, provided your process controls moisture and your directions tell consumers to shake.

Is creatine HCl or another salt form more soluble?

Yes, on paper. Gufford et al. (2010) measured creatine hydrochloride as about 38 times more soluble in water than creatine monohydrate, and Jäger et al. (2011) report creatine citrate at 29 g per litre and creatine pyruvate at 54 g per litre at 20 °C. Solubility rises as pH falls, and saturated citrate and pyruvate solutions are strongly acidic (pH 3.2 and 2.6).

Three caveats before switching forms:

1. More soluble is not more effective. Higher solubility means less water per serving. It does not mean more creatine absorbed, and no EU claim exists for it.
2. The EU claims were assessed on creatine monohydrate. The two authorised claims (Regulation (EU) 432/2012 and 2017/672) require 3 g of creatine a day. Check novel food and claim status for any other form; see our EU compliance guide.
3. Acidity speeds breakdown in drinks. Lower pH helps creatine dissolve but also speeds its conversion to creatinine (see below).

For most brands the practical route is creatine monohydrate in the finest grade they can source with documentation.

Which branded creatine ingredients exist, and what do they publish?

The table compares what each supplier publicly states about form, purity and particle size. It covers the ingredients brands most often ask us about, not the whole market, and it was checked in October 2026.

Ingredient (supplier)	Form	Published purity	Published particle size	What it means for mixing in water
Creavante (CAPSENA d.o.o., Slovenia)	Creatine monohydrate	HPLC ≥ 99.9 %, creatinine ≤ 30 ppm, per lot	500 mesh nominal (≈ 25 µm), laser diffraction	Fine grade for fast dissolution; same 14 g/L limit as all monohydrate
Creapure (AlzChem Trostberg, Germany)	Creatine monohydrate	99.9 %, DCD < 20 mg/kg, DHT not detectable	Not found on creapure.com	Monohydrate; ask for the particle-size distribution of the grade you are quoted
CON-CRĒT (ProMera / Vireo Systems, USA)	Creatine hydrochloride	Not stated on the listing we checked	Not stated	Much higher solubility (about 38× monohydrate, Gufford 2010); check EU status
Kre-Alkalyn (All American Pharmaceutical, USA)	Buffered creatine	Not stated on the listing we checked	Not stated	Marketed as stable in liquid; Jagim et al. (2012) found no advantage over monohydrate
Creatine MagnaPower (Albion / Balchem, USA)	Magnesium creatine chelate	Not stated on the official page	Not stated	No solubility claim published

If you buy creatine monohydrate from anyone, including us, ask for three numbers on the certificate: the HPLC assay, the creatinine result and a laser-diffraction particle size (D50 and D90 in microns). A mesh number with no micron data is a sales description. Our 500 mesh guide explains why sieves cannot verify grades that fine.

Can creatine go into a ready-to-drink product?

Only with care. Dry creatine monohydrate is very stable: Jäger et al. (2011) report no degradation after more than three years at 40 °C. In water it is a different story, and pH decides the rate. Howard and Harris (1999), as cited by Jäger, measured degradation after three days at 25 °C of:

• about 4 percent at pH 5.5
• about 12 percent at pH 4.5
• about 21 percent at pH 3.5

Many flavoured drinks and juices sit around pH 3 to 4. Ganguly et al. (2003) found 90 percent degradation in 45 days at 25 °C in an effervescent creatine citrate solution starting at pH 3.6. That is why the formats that work are those mixed shortly before drinking: powders, sachets, effervescent tablets and dual-chamber caps. A fine grade suits all of them because it dissolves in the time it takes to shake.

What should a brand specify?

For a creatine that mixes clear, tastes clean and stays free-flowing:

1. Creatine monohydrate, CAS 6020-87-7, so the EU claims apply at 3 g a day.
2. Particle size by laser diffraction: 500 mesh nominal, about 25 µm, for drinks, sachets, effervescents and gummies.
3. Creatinine on every lot, as low as you can get (Creavante: ≤ 30 ppm), plus DCD, DHT and heavy metals; see creatine purity and impurities.
4. Loss on drying of 0.5 percent or less, sealed packaging and dry storage, so fine powder stays free-flowing.
5. Directions on pack: at least 250 ml of water for 3 g, shake or stir while adding, and drink soon after mixing.

Creavante is made to that specification and supplied from EU stock with a certificate of analysis for every lot. Request a sample kit and test it in your own water and flavour system next to whatever you use now.
