Liposomal creatine

What liposomal actually means

A liposome is a tiny lipid vesicle: a bilayer of phospholipids like a cell membrane, only as a sphere, watery inside, fat-soluble outside. An active ingredient can be packed inside it; the vesicle is meant to protect it in the stomach and escort it through the intestinal wall.

This is not an invention of the supplement industry: liposomal cancer drugs have been approved for decades, and for vitamin C the technique is seriously discussed, because its absorption collapses above a certain dose. It has only one precondition: something must be lost with the active ingredient. A liposome cannot solve a problem that does not exist.

The number every packaging has to be measured against

Creatine monohydrate is one of the best-studied supplements of all, and absorption is its best-documented aspect. The 2022 review by Kreider and colleagues summarizes it as follows: less than 1 percent breaks down to creatinine in the stomach, 99 percent ends up in the blood and from there in the tissues or in the urine.

Going from 99 to 100 gains 1 percentage point — the upper limit of what a shell could achieve for absorption. For creatine, better absorption is therefore not a promise of innovation but an arithmetic error.

Where the numbers on the package come from

The best-known product is Liposomal Advanced Creatine from Cymbiotika: liquid, 24 sachets of 5 grams of creatine each, just under 65 euros in Germany. The package states 15 percent better absorption, 21 percent more creatine, no bloating, clinically studied. These numbers are not made up — they come from a real study, just not one about liposomes.

The raw material in it is a creatine monohydrate with the brand name CreaBev from Glanbia, which dissolves particularly well in liquid. There is a 2022 study on it: 37 trained men, a dose of 5 grams, followed by 6 hours of blood sampling. With one of the variants, the area under the blood curve was around 15 percent higher than with normal monohydrate, and the peak value around 21 percent. What was measured was powder in water; the liposomes only come in later.

What else is on the market

Codeage sells Liposomal Creatine as a dry powder, 90 servings of 5 grams for around 50 dollars; the liposomal part is admixed sunflower lecithin, and the company gives no absorption figures at all. That is the more honest variant — but dry powder with lecithin is still just powder with lecithin. KRĒO offers Creatine Plus with 2 additives, 30 servings for around 60 dollars, and links to general literature, not a study on creatine.

Why more in the blood does not mean more in the muscle

Here the raw material study itself helps. It was funded by the manufacturer Glanbia, which is openly stated in it, and its authors write, in essence, that it is unknown whether the small differences in the blood curve mean anything physiologically — because monohydrate is practically completely absorbed.

They are right about that. The muscle takes up creatine via a transporter, and that is the bottleneck, not the gut. What it does not take up is excreted by the kidneys — so a higher peak value in the blood can mean that it leaves again more quickly. For monohydrate, muscle content has often been measured by biopsy; for liposomal creatine, not a single time.

The tenth better packaging

Liposomal is not the first special form but roughly the tenth, and its predecessors have been tested. Creatine ethyl ester breaks down to creatinine in the stomach more than monohydrate does, so it is less available rather than more. Buffered creatine showed no advantage in 36 strength athletes over 28 days, neither in the muscle nor with the barbell. Creatine nitrate at a low dose could not be distinguished from placebo. New form, big promise, and when someone measures cleanly, it comes out level or behind.

What the studies show

Kreider et al. 2022 — the review of creatine forms

Less than 1 percent of swallowed creatine breaks down to creatinine in the stomach, 99 percent reaches the blood. The paper goes through the special forms: monohydrate is the only form with solid evidence for availability, efficacy and safety.

CreaBev study 2022 — the source of the package numbers

What was studied was the raw material, not a liposomal product: 37 trained men, single dose of 5 grams, 6 hours of blood sampling. Area under the blood curve around 15 percent, peak value around 21 percent above normal monohydrate. Funded by the raw material manufacturer; the authors themselves call it unclear whether such differences mean anything physiologically.

Buffered creatine versus monohydrate — 36 strength athletes, 28 days

No advantage, neither in the muscle nor with the barbell — representative of the special forms as a whole.

Review from Split 2026 — 343 studies, 5 comparisons

The group reviewed all 343 randomized creatine studies since 1994. Only 5 compared two creatine forms with each other at all, mostly with different amounts of creatine in the arms. The question of the better form has therefore practically never been asked cleanly.

Where there are no data at all

On liposomal creatine as a dietary supplement in humans, there is not a single publication in the medical database PubMed. Not a small one, not a poor one — none. This means that neither of the two promises has been tested: better absorption has never been measured with a liposomal creatine product, neither in the blood nor in the muscle, and neither has better tolerability.

This is an argument in both directions: it does not prove that a lipid shell is useless, because nobody has checked. It only shows that the 99 percent were already in place beforehand — and that the burden of proof lies with whoever charges the surcharge.

Status, approval and legal

In Germany, creatine is freely available as a dietary supplement, including as a liposomal preparation; there is no marketing authorization as a medicine, and creatine is not on the World Anti-Doping Agency’s Prohibited List. The products examined come from the US and are priced at 2 to just over 10 times as much: around 50 cents per gram for Cymbiotika (120 grams for 65 euros), around 11 cents for Codeage (450 grams for 50 dollars), compared with 4 to 5 cents for half a kilo of monohydrate from German retailers at 18 to 23 euros.

Safety

In all products examined, the active ingredient is monohydrate, whose safety record is among the longest observed in the supplement field. There are no separate safety data for the liposomal preparation, because there are no studies on it at all; phospholipids and sunflower lecithin are common food ingredients. The tolerability problem that the products aim to solve is real: some people tolerate 5 grams of powder at once poorly, especially in the loading phase — water in the gut, a feeling of fullness, occasionally diarrhoea. Whether a lipid shell changes anything about this has never been studied. Anyone with kidney problems should talk to a doctor beforehand.
