Transparent Labs Creatine vs Thorne (2026 Comparison)
By Kazi Habib, B.Pharm, MBA, PMP · Updated May 19, 2026
For the lifter who wants Creapure sourcing at the lowest available price with per-batch COA transparency, Transparent Labs StrengthSeries Creatine HMB wins at roughly $0.50 per 5 g serving (or roughly $0.42 for the basic Creatine SKU without HMB). For the lifter who prioritizes NSF Certified for Sport certification and pharmaceutical-grade clinical sourcing for medical or sport-regulator contexts, Thorne Creatine wins at roughly $0.55 per 5 g serving. Both use Creapure or pharmaceutical-grade creatine monohydrate; the differentiation is in certification and the additional HMB ingredient.
TL;DR
- Best for NSF Certified for Sport (medical / regulator contexts): Thorne Creatine.
- Best for per-batch COA transparency: Transparent Labs.
- Best value among premium creatines: Transparent Labs basic Creatine SKU (~$0.42/serving).
- Best for clinical / functional medicine integration: Thorne.
- Best for cutting athletes wanting HMB stack: Transparent Labs Creatine HMB.
Why trust this review
I am Kazi Habib, B.Pharm, MBA, PMP, with 10+ years across pharmaceutical sciences and life-sciences marketing. I purchased both products at full retail price in early 2026 for a creatine sourcing audit, cross-referenced the published Certificates of Analysis and NSF Certified for Sport database entries. None of the brands paid for inclusion.

Head-to-head spec comparison
| Spec | TL Creatine HMB | Thorne Creatine |
|---|---|---|
| Active creatine | 5 g (Creapure) | 5 g (pharm-grade) |
| Other actives | 2 g HMB | None |
| Source label | Creapure | Pharm-grade (unbranded) |
| Third-party testing | Per-batch COAs published | NSF Certified for Sport |
| Halal certification | None in NA | None in NA |
| Form | Flavored powder + unflavored | Unflavored powder only |
| Cost per serving (US) | ~$0.50 (~$0.42 basic SKU) | ~$0.55 |
Both are premium-priced (3-5x the price of Nutricost or generic creatine monohydrate). Thorne's premium pays for NSF Certified for Sport. Transparent Labs' premium pays for Creapure source and the optional HMB stack.
Where Transparent Labs Creatine wins
Per-batch published COAs. Every Transparent Labs product publishes a batch-specific Certificate of Analysis on the product page, showing heavy metals, microbial counts, and pesticide screens where applicable. The COA is current to the batch you receive.
Creapure source labeling. Transparent Labs uses Creapure brand creatine monohydrate from AlzChem (Germany), the most-audited creatine source in the category. Thorne uses pharmaceutical-grade creatine but does not specifically brand the source as Creapure.
Optional HMB stack. The StrengthSeries Creatine HMB SKU adds 2 g of HMB per serving. HMB has modest evidence for reducing muscle protein breakdown during caloric deficit. If you are already cutting and want creatine and HMB in one scoop, the combination is convenient.
Cost per serving (basic SKU). Roughly $0.42 per serving for the no-HMB version is the cheapest premium-Creapure creatine in this comparison.
Flavored options. Transparent Labs offers Blue Raspberry, Strawberry Lemonade, and Tropical Punch versions. Thorne is unflavored only.
Where Thorne Creatine wins
NSF Certified for Sport. This is the headline differentiator. Thorne Creatine carries NSF Certified for Sport, the certification mark recognized by MLB, NFL, NHL, PGA Tour, US Olympic & Paralympic Committee, and LPGA. Informed Sport (carried by Optimum Nutrition) is equivalent in screening rigor but NSF Sport is more universally recognized in North American pro sport. Transparent Labs does not carry NSF Sport.
Clinical prescribing track record. Thorne is the supplement brand most commonly prescribed by US functional medicine clinicians, integrative physicians, and registered dietitians. The brand maintains the Thorne Marketplace (a B2B portal for licensed practitioners).
Established research partnerships. Thorne has long-standing partnerships with Mayo Clinic and other academic institutions; the brand funds clinical trials on its own products at higher rates than typical supplement manufacturers.
Pharmaceutical-grade processing. FDA-registered manufacturing following pharmaceutical-grade GMP standards.
Simpler product (single ingredient). Thorne Creatine is unflavored creatine monohydrate, period. No HMB, no flavor system, no carrier ingredients.
Halal certification analysis
Creatine monohydrate is chemically synthesized from sarcosine and cyanamide; no animal-derived precursors. By ingredient class, both products are halal-friendly. Neither brand carries formal halal certification in North America. For halal-strict consumers who specifically want facility-level audit confirmation, Thorne's NSF Sport-certified facility adds a cross-contamination control layer (though NSF Sport is not a halal mark). Transparent Labs' per-batch COAs are valuable for ingredient-level verification but do not address facility-level halal questions. Neither brand has invested in formal IFANCA certification.
Canadian market: cost and availability
Transparent Labs in Canada. No retail distribution. Direct-ship from US warehouses with CAD $15-25 freight per order. Total effective cost: CAD $0.65-0.80 per serving for the basic Creatine (subscription); CAD $0.75-0.95 for the Creatine HMB SKU.
Thorne in Canada. No mainstream retail distribution. Direct-ship from Thorne.com to Canadian addresses with CAD $15-20 freight. Some Canadian functional medicine clinics carry Thorne through the Thorne Marketplace; if your healthcare provider already prescribes Thorne, your clinic may order it at a discount. Total effective cost direct-ship: CAD $0.85-1.05 per serving including freight.
Canadian alternative note. ATP Lab (Quebec-manufactured) and Mammoth Supplements (Canadian-manufactured) both use Creapure in Canadian-distributed creatine products at lower cost than US direct-ship brands.
Pharmacist take
NSF Sport is the differentiator that matters most in regulated contexts. For drug-tested professional athletes, NSF Certified for Sport is the certification trainers and medical staff specifically require. If you are subject to drug testing in MLB, NFL, NHL, PGA, USOPC, or LPGA, Thorne is the safer pick.
HMB adds a small ergogenic benefit in specific contexts. The Wilson 2013 ISSN position stand on HMB summarized the evidence: HMB at 3 g/day shows modest benefits for muscle protein preservation during cuts, with stronger effects in untrained populations. The 2 g in Transparent Labs is below the typical clinical dose.
Thorne's clinical prescribing position is structurally different. For patients whose physician or naturopath is already prescribing Thorne products, brand consistency is a real benefit; the clinician has visibility into the patient's full supplement protocol.
Dosing both correctly
Maintenance dose. 5 g per day of creatine monohydrate. Timing relative to workout is not critical per Kreider 2017.
Loading (optional). 20 g/day in 4 divided 5 g doses for 5-7 days, then drop to 5 g/day maintenance.
Contraindications. Chronic kidney disease (eGFR under 60) requires nephrology consultation. Creatine raises serum creatinine slightly through metabolism; inform your physician you are taking creatine before blood work.
Who should pick which
- The drug-tested NSF Sport-required athlete. Pick Thorne Creatine.
- The lifter who specifically wants Creapure source disclosed. Pick Transparent Labs basic Creatine SKU.
- The cutting athlete who wants HMB stacked. Pick Transparent Labs Creatine HMB.
- The patient whose physician already prescribes Thorne. Pick Thorne for brand consistency.
- The premium-creatine buyer optimizing for cost. Pick Transparent Labs basic Creatine SKU (~$0.42/serving).
- The cost-sensitive lifter overall. Pick neither; pick Nutricost Creatine Monohydrate at $0.06/serving for the same active molecule.
Bottom line
For drug-tested athletes requiring NSF Certified for Sport, Thorne wins. For lifters who want Creapure source disclosure and per-batch COA transparency, Transparent Labs wins. Active molecule is identical; the choice is about certification, sourcing transparency, and the optional HMB stack. For general use, both are premium-priced and Nutricost delivers the same active molecule at one-eighth the cost.
Frequently Asked Questions
Equivalent for the active ingredient; both deliver pharmaceutical-grade creatine monohydrate at 5 g per serving. Thorne wins on NSF Certified for Sport (critical for regulated athletes); Transparent Labs wins on Creapure source labeling and per-batch COA transparency.
Thorne's pricing reflects pharmaceutical-grade manufacturing, NSF Certified for Sport audit, clinical prescribing infrastructure, and research investment. The active molecule is the same as cheaper brands. For consumers who do not need the certification, generic creatine monohydrate works equally well at one-fifth the price.
Same molecule; published trials do not show outcome differences by source. Creapure has the cleanest impurity audit chain. For consumers who weight manufacturing transparency, Creapure-branded products like Transparent Labs are the cleaner pick. For general use, both work identically.
Modest evidence for reducing muscle protein breakdown during caloric deficit per the Wilson 2013 ISSN position stand. Stronger effects in untrained populations; weaker effects in trained populations. The 2 g per serving in Transparent Labs Creatine HMB is below the typical 3 g/day clinical dose. Convenient stack; not a transformative addition.
Thorne Creatine. NSF Certified for Sport is the certification mark Major League Baseball, NFL, NHL, PGA, USOPC, and LPGA medical staff specifically require. Transparent Labs does not carry NSF Sport.
Creatine monohydrate is halal-friendly by ingredient class (synthesized, non-animal-derived). Neither brand carries formal halal certification. Thorne's NSF Sport-certified facility adds a cleanliness audit layer that Transparent Labs does not have.
