Creatine Ireland: An Evidence-Based Buyer's Guide to CreaPure® Creatine Monohydrate

Creatine is no longer a bodybuilder-only supplement. This guide explains creatine monohydrate and CreaPure® purity for an Irish audience, covers what the evidence does and does not support, and shows how to choose between powder and capsules.

Creatine (creatine monohydrate) definition: Creatine is a compound made naturally in the body from the amino acids arginine, glycine and methionine, stored mostly in skeletal muscle as phosphocreatine, and also obtained from the diet in red meat and fish.

What is creatine and how does it work?

Creatine is a naturally occurring compound your body makes from three amino acids: arginine, glycine and methionine. Around 95% of it is stored in skeletal muscle, with a small amount in the brain.

In muscle, creatine is held as phosphocreatine. During short, hard efforts it donates a phosphate group to rapidly regenerate ATP, the cell's immediate energy currency. This is why its clearest benefit is in brief, repeated, high-intensity work rather than long endurance efforts.

You also get creatine from food, mainly red meat and fish. Vegetarians and vegans tend to have lower dietary intake and lower baseline muscle stores, which is one reason supplementation can be relevant beyond sport.

Creatine forms: monohydrate vs HCl and others

Several creatine forms are marketed, but the research base is not evenly spread. Creatine monohydrate is by far the most studied and is the reference form used in the overwhelming majority of trials.

Newer forms such as creatine HCl, buffered creatine (Kre-Alkalyn) and creatine gummies are often sold on claims of better absorption or fewer side effects. The International Society of Sports Nutrition position stand (Kreider et al., 2017)¹ concludes that monohydrate remains the most effective and best-supported form, and that alternative forms have not been shown to be superior.

For most people in Ireland, the practical decision is not which exotic form to pick. It is monohydrate in a format you will take consistently, from a source you trust.

What CreaPure® is and why purity matters

CreaPure® is a branded creatine monohydrate produced in Germany by AlzChem. Chemically, it is the same molecule as any creatine monohydrate. The difference is in how it is made.

CreaPure is manufactured to a controlled, pharmaceutical-grade purity standard with tight limits on the production by-products that can appear in lower-grade creatine. It is also produced synthetically rather than from animal sources, which is why CreaPure products are suitable for vegetarians and vegans.

The honest framing is this: purity and traceability are the reason to choose CreaPure, not a different or stronger active ingredient. If you want a creatine monohydrate with a known German manufacturing origin and consistent quality, CreaPure is a defensible choice. That is why Probiotic.ie stocks CreaPure specifically rather than commodity creatine.

Powder or capsules: which format?

Both use the same CreaPure® creatine monohydrate. The practical differences are cost per day, capsules per day, and vegan suitability.

For most daily users the powder is the lower-cost, vegan choice. The capsules earn their place for travel and convenience, accepting a higher cost per day and a bovine-gelatine shell in exchange for no mixing and no taste.

What the evidence supports: the authorised claims

Creatine is unusual among supplements because it has authorised EU health claims. These are specific wordings that regulators permit because the evidence met the required standard. Most supplements have none.

Using the authorised wording, at the authorised dose, is the compliant way to describe what creatine does. Below are the two authorised claims, followed by the one that was assessed and rejected.

Creatine for women

Creatine is not a male-only supplement. Women naturally carry 70–80% lower endogenous creatine stores than men, according to the lifespan review by Smith-Ryan and colleagues (Nutrients, 2021)³.

That review reports creatine supports strength and exercise performance in women, with effects broadly similar to men, and highlights potential relevance across the female lifespan, including the post-menopausal years when combined with resistance training. In the interest of transparency: two of that review's authors disclosed that they act as scientific advisers to AlzChem, the manufacturer of CreaPure. We cite the review for its data, and note the disclosure.

For the many Probiotic.ie customers who are not bodybuilders, this is the practical point: creatine is a general strength and muscle-retention supplement, and women start from a lower baseline. The over-55 authorised strength claim applies to women and men alike.

Creatine for older adults and muscle retention

Muscle loss with age (sarcopenia) is a major driver of falls and loss of independence. Resistance training is the primary tool, and creatine has an authorised EU claim specifically in this context.

In adults over 55, 3 g/day of creatine combined with regular resistance training, at least three times a week, can enhance the strength effect of that training (Commission Regulation (EU) 2017/672). The key word is "combined": the claim is about improving what training already does, not replacing it.

This makes creatine one of the few supplements with a regulator-backed role in healthy ageing, provided it is paired with the training the claim requires.

Creatine and cognition: the honest picture

Creatine and brain function is one of the fastest-growing areas of supplement marketing, so it deserves a straight answer. Creatine does contribute to brain phosphocreatine, and there is a plausible mechanism for effects under energy stress such as sleep deprivation or ageing.

The current human evidence is genuinely mixed. The 2023 meta-analysis by Prokopidis and colleagues⁴ found small memory improvements in healthy people, but that result drew a published methodological critique, and follow-up analyses have been cautious.

Crucially, the European Commission formally refused a creatine cognitive-function claim in May 2026 through Commission Regulation (EU) 2026/1118⁶, following an EFSA opinion that a cause-and-effect relationship had not been established. So while the research is worth watching, there is no authorised EU claim that creatine improves memory or cognition, and Probiotic.ie does not make one.

Dosing: loading vs daily use

There are two evidence-based ways to start, and they end in the same place.

Daily use (simplest): take 3–5 g every day. Muscle stores saturate over roughly three to four weeks. This is the approach most people use and it needs no calculation.

Loading (faster): take around 20 g/day, split into four smaller doses, for 5–7 days, then drop to 3–5 g/day to maintain. This saturates stores in under a week. The trade-off is more powder and a slightly higher chance of mild stomach upset early on.

Timing across the day is a minor factor. Total daily intake and consistency are what drive the result. Take it every day, including rest days.

Safety: kidneys, hair loss and water retention

Creatine is one of the most-studied supplements, and its safety profile in healthy adults is reassuring. The common concerns are worth addressing directly.

Kidneys: in healthy adults at recommended doses, creatine has not been shown to damage kidney function (Kreider et al., 2017)¹. It can raise serum creatinine slightly, because creatine is metabolised to creatinine, which can make an eGFR estimate look worse without any real change. Anyone with existing kidney disease should check with their GP first.

Hair loss: the worry traces to one 2009 study in 20 rugby players that reported a shift in the DHT-to-testosterone ratio over three weeks⁵. That study did not measure hair loss, has not been replicated, and later reviews (Antonio et al., 2021)² found no trial showing creatine causes baldness.

Water and weight: a small early rise in weight is usually water drawn into muscle cells, not fat and not surface bloating. It is typically 1–2 kg and is a normal osmotic effect, not a sign of harm.

Creatine in Ireland: status, VAT and where to buy

Creatine monohydrate is a legal food supplement in Ireland, regulated by the Food Safety Authority of Ireland (FSAI). It is not a medicine and not a controlled or banned substance.

The two authorised EU health claims (physical performance, and muscle strength in over-55s with resistance training) apply in Ireland under the EU nutrition and health claims framework. On VAT: general food supplements moved to the 13.5% reduced rate in January 2020, but Revenue has treated sports nutrition supplements, and products bearing EU authorised health claims, differently. The applicable rate for a given creatine product should be confirmed with Revenue or an accountant; prices shown on Probiotic.ie already include Irish VAT.

Probiotic.ie stocks Reflex Nutrition CreaPure® Creatine in Ireland in two formats: an unflavoured, vegan 500g powder (100 servings, €34.95) for daily use, and 90 capsules (€14.95) for travel and convenience. Both use the same CreaPure creatine monohydrate; the capsules use a bovine-gelatine shell and are not suitable for vegetarians or vegans. Both ship next-day dispatch from Dublin. You can compare both on the CreaPure creatine collection.
