Transparent Labs Creatine Review UK 2026

Transparent Labs built its reputation on a single promise: you can see exactly what is in every product. For a creatine supplement, that is a meaningful claim - because the creatine market has a persistent problem with underdosed products, fillers, and labels that do not match what is actually inside the tub. Whether that promise holds up under scrutiny is what I set out to verify.

I am Clemmie Rose, a registered Nutritional Therapist and BANT member, holding a Diploma in Nutritional Therapy from the College of Naturopathic Medicine. I review supplements by checking what the research actually supports, reading the label in full, and looking for the third-party documentation that turns a marketing claim into a verifiable fact. This review of Transparent Labs Creatine HMB does exactly that - and flags two things most UK buyers do not check before ordering.

Overall verdict: Transparent Labs Creatine HMB delivers the dose it claims (5g creatine monohydrate, 1,500mg myHMB), has legitimate third-party certification, and does not use artificial sweeteners. The premium is real, especially at UK landed cost. Whether it is worth it depends almost entirely on whether you have a reason to want HMB alongside your creatine.

Transparent Labs is a US supplement brand founded in 2015, with headquarters in Salt Lake City, Utah. The core brand proposition from launch has been full ingredient disclosure - no proprietary blends, exact doses listed, no undisclosed fillers. The brand's products carry "no artificial sweeteners, no artificial colouring, no artificial flavors or preservatives" on every label.

In the UK, Transparent Labs does not operate a direct shipping route that makes commercial sense for most buyers. The primary UK retail channel is Healf (healf.com), a UK-based premium supplement retailer. Products also appear on Amazon, including through third-party marketplace sellers - a distinction that matters and that I address in the UK availability section below.

The brand's Trustpilot UK profile shows 4.6 stars across 452 reviews as of the time of writing. Complaints centre on shipping times and, for UK buyers, customs charges and price. The product itself receives consistently positive reviews.

This is the section most UK buyers skip, and it is the one that justifies or undermines the premium.

Creatine monohydrate: the dose checks out. Each serving contains 5g of creatine monohydrate. This matches the loading and maintenance dose supported by the International Society of Sports Nutrition (ISSN), whose position stand on creatine supplementation is the most widely referenced consensus document in this space. The ISSN has consistently supported 3-5g daily for maintenance, making 5g a full, effective dose.

On the creatine source: Creapure is not confirmed. Some reviews and comparison articles have assumed the creatine in Transparent Labs products is Creapure-branded (the German-manufactured monohydrate from AlzChem, widely considered the highest-purity commercial source). The current label and published product page do not specifically state Creapure. The brand markets the product as 100% pure creatine monohydrate with third-party testing, but the source manufacturer is not named on the label at the time of writing. UK buyers who want Creapure specifically should contact Transparent Labs directly before purchasing, or look at brands that explicitly state the Creapure trademark on-label.

HMB: what it is and what the research actually says. HMB stands for beta-hydroxy beta-methylbutyrate, a metabolite of the amino acid leucine. Transparent Labs uses the myHMB branded form (from TSI Group), which is the version with the most supporting research. The dose here is 1,500mg - which is within the studied range (1.5g to 3g daily is typical in the literature). The research on HMB is more nuanced than the marketing suggests. A 2017 ISSN position stand on beta-hydroxy beta-methylbutyrate found benefits in attenuating lean mass loss during caloric restriction and in untrained individuals beginning a resistance programme. For trained athletes already eating adequate protein, the evidence for HMB as an additive benefit is less consistent. I cover the "is HMB worth the extra money" question directly in the FAQ. For a full breakdown of how monohydrate compares to other forms, see our guide to creatine monohydrate vs HCL.

Two additional ingredients most reviews do not mention. The full formula also contains Vitamin D3 at 500 IU (12.5mcg) and BioPerine at 5mg. BioPerine is a patented black pepper extract (piperine) included to enhance absorption of certain nutrients. At 5mg, it is within the standard usage range. Vitamin D3 at 500 IU is a modest dose - useful as a maintenance contribution but not a therapeutic level on its own. Neither ingredient raises a safety concern, but UK buyers reading the label for the first time should know these are present. A product marketed on full ingredient transparency should have full ingredient transparency in its reviews.

Third-party testing: confirmed, with a caveat. Transparent Labs products are certified by Informed Sport, a respected third-party testing programme run by LGC Group that tests for prohibited substances banned by WADA and UKAD. This is a genuine certification - not a self-certification. However, it is worth understanding what Informed Sport certifies: it confirms the product does not contain prohibited substances. It confirms the supplement is safe for competitive athletes to use without triggering a positive drug test. It is not the same as a batch-matched COA confirming exact creatine dose per gram. Buyers who want dose-specific batch documentation should request the COA via the Transparent Labs website directly.

The brand is more transparent than most in its category. The testing claim holds up under scrutiny, with the understanding that Informed Sport certification and a dose-verification COA serve different purposes - and the former is what Transparent Labs provides as standard.

Creatine monohydrate is well understood at a functional level. The performance differences between products in the same category are almost entirely about palatability and digestive comfort, not efficacy. On those measures:

Unflavoured: Transparent Labs produces an unflavoured version of Creatine HMB that mixes cleanly into water. There is no notable grittiness when mixed into 250-300ml of water. The lack of sweetener means no aftertaste. For buyers who stack creatine into a protein shake or take it with a flavoured drink, this is the most practical option.

Flavoured versions: Transparent Labs offers 13 flavours including Black Cherry, Peach Mango, and Watermelon, all sweetened with stevia. Stevia is a natural, non-caloric sweetener with a well-established safety profile. What Healthline notes, and what the brand's own reviews confirm, is that the stevia aftertaste is noticeable - not overwhelming, but distinct. Buyers who are sensitive to that specific sweetness profile should be aware before ordering a large tub.

Digestive comfort: Creatine monohydrate is generally well tolerated. The addition of 1,500mg HMB does not introduce significant digestive complexity for most users. Taking the serving with a meal further reduces any risk of gastric discomfort.

One practical note: the flavoured versions taste materially different from plain monohydrate dissolved in water. That is not a flaw - it is a product category difference. If you are used to unflavoured monohydrate and expect the flavoured version to taste like a sports drink, you will be surprised. Set expectations accordingly.

This is where the Transparent Labs premium becomes a genuine purchasing decision rather than a lifestyle preference.

UK retail channel: The primary route for UK buyers is Healf (healf.com). Healf is an established UK supplement retailer and is a legitimate source. Prices at time of writing range from approximately £46.49 for the unflavoured or single-flavour option to £89.99 for 60-serving tubs in certain flavours. The exact price varies by flavour and serves available.

US direct comparison: In the US, the same product retails at $49.99 direct from Transparent Labs for a standard tub. At current exchange rates and without shipping or import considerations, UK buyers are paying materially more. This is a function of retailer margin, import logistics, and the absence of a direct UK fulfilment route. It is not a Transparent Labs policy - it is the cost structure of importing US supplements to the UK.

Counterfeit risk on marketplaces: This is a genuine issue that warrants direct mention. A thread on r/Supplements documented a confirmed counterfeit Transparent Labs Creatine HMB unit purchased through an eBay seller. Amazon third-party marketplace listings carry similar risk for any premium supplement brand. The safest UK purchase route is Healf or direct from Transparent Labs US, accepting the shipping cost and potential import duty. Buying through third-party marketplace sellers - particularly on eBay - carries counterfeit risk for this specific product.

Affiliate note: At the time of writing, no UK-serviceable affiliate programme is active for Transparent Labs via Balance Journal's affiliate networks. The link to Healf below is a direct editorial referral.

Buy if: You are a competitive athlete who needs Informed Sport certification. You want an HMB stack without managing two separate products. You prioritise label transparency and no artificial sweeteners above value per gram of creatine. You are buying via Healf and have factored in the UK price premium.

Do not buy if: You are a trained athlete who eats adequate protein and does not have a specific reason to want HMB (the evidence for additional benefit is limited). You want Creapure specifically and need on-label confirmation. You are price-sensitive and a straightforward creatine monohydrate from a best creatine shortlist will serve the same creatine function at lower cost.

The honest summary: Transparent Labs delivers on its core transparency promise - doses are accurate, testing is real, ingredients are disclosed. The UK price premium is a commercial reality, not a quality indicator. Buy it for the HMB stack and Informed Sport certification. Do not buy it expecting a meaningfully superior creatine outcome versus a well-dosed plain monohydrate.
