Transparent Labs vs Momentous vs Thorne: A Real Three-Way Comparison
All three brands describe themselves as third-party tested, but they are not tested the same way, priced the same way, or built for the same buyer. Here is a direct comparison on the specifics that actually differ — testing program, label disclosure, price per serving, and who each one is genuinely built for.
Testing Program: Informed-Choice vs NSF Certified for Sport
“Third-party tested” is not one standard, and the three brands compared here do not all use the same program. Transparent Labs applies Informed-Choice batch testing to select product lines — a program that screens for substances banned in competitive sport and verifies batch-level label accuracy. Momentous and Thorne both use NSF Certified for Sport, which does the same core job but is the specific standard named in the drug-testing policies of several major U.S. pro leagues, and is generally considered the stricter and more widely recognized of the two in a North American context.
None of the three programs evaluates whether an ingredient works at the dose used, or compares one brand’s version of an ingredient favorably against another’s. All of them are about testing and label verification, not about the underlying evidence for the ingredient itself — a distinction worth holding onto through the rest of this comparison.

The Budget Baseline: What’s Actually on Amazon
Before paying any certification premium, know what the uncertified commodity option costs. These are the widely available basics every brand in this comparison is measured against.
NOW Sports Whey Protein Isolate, Unflavored
A widely available isolate at a meaningfully lower per-serving cost than any of the three certified brands compared here, with a comparable core protein content.
Search on Amazon →Nutricost Creatine Monohydrate, Micronized
The same core compound sold by every certified brand in this guide, without the testing premium — a reasonable choice for a non-tested buyer.

Lets you verify any scoop or capsule-based product from any of the three brands is actually delivering close to its labeled amount.

Transparency: What Each Brand Actually Discloses on the Label
Transparent Labs’ specific claim is full ingredient disclosure across its entire catalog — every active ingredient listed at its exact milligram or gram amount, with no proprietary blends anywhere in the current lineup. That is the sharpest transparency claim of the three, and it is the most useful for a buyer who wants to check every number on a label against a published trial’s dosing range without guessing.
Momentous’ transparency comes from a different design choice: most of its core products are single-ingredient (plain creatine, a whey isolate, an omega-3) rather than multi-ingredient blends, so there is little blend math to disclose in the first place. Thorne sits in between — its single-ingredient products (creatine, magnesium, zinc) are as transparent as Momentous’ by default, while its combination formulas, like Basic Nutrients 2/Day, involve more ingredients and more label real estate to evaluate.

- Transparent Labs: broadest full-disclosure claim, applied to multi-ingredient formulas specifically.
- Momentous: transparency by simplicity — fewer ingredients per product to disclose.
- Thorne: transparent on single-ingredient products; broader catalog means more combination formulas to evaluate case by case.
Product Range: Sports Nutrition vs a Full Catalog
Transparent Labs and Momentous both stay narrowly focused on sports nutrition — pre-workout, protein, creatine, and a small number of adjacent products. Thorne’s catalog is meaningfully broader, extending into general multivitamins, individual minerals like magnesium and zinc, vitamin D/K2 combinations, and other categories that have nothing to do with training or recovery. That breadth is a real differentiator for a buyer who wants one certified source across multiple categories rather than shopping brand by brand.
The trade-off is focus. A narrower catalog, like Momentous’, is easier to evaluate end to end since there are fewer products to check, while Thorne’s breadth means quality and price positioning can vary more from product to product within the same brand. Check Thorne Pricing →
Price Per Serving: Creatine and Whey, Compared Directly
Using creatine monohydrate as the clearest common reference point, since it is a single, well-understood ingredient sold in a comparable dose by all three brands: Momentous commonly runs about $1.30 to $1.70 per serving, Thorne about $1.10 to $1.40, and Transparent Labs bundles its creatine into a combination formula rather than selling it as a standalone product at a directly comparable per-serving price. All three sit well above an uncertified generic tub from NOW or Nutricost, which typically runs $0.20 to $0.40 per serving at a similar micronized quality.
Whey isolate pricing is closer across the three certified brands, generally landing in a $1.50 to $2.00 per-serving range depending on flavor and current promotions. The larger gap in every case is between any of the three certified brands and the uncertified commodity alternative, not between the three certified brands themselves.
Subscription Terms: What Recurring Orders Actually Save
All three brands offer a subscription discount for recurring orders, and in every case the subscription rate meaningfully changes the real cost per serving compared with a one-time purchase. Anyone doing a genuine cost comparison — between these three brands, or against a generic alternative — should price the subscription rate rather than the list price, since the gap between the two is often the difference between a defensible premium and an indefensible one.
Specific subscription percentages, minimum commitment terms, and cancellation policies change over time across all three brands, so check each one’s current terms directly before committing to a recurring order, particularly on a flavor or formula you have not tried.
Best-For Verdicts: Matching the Brand to the Buyer
Choose Transparent Labs if your priority is verifying every dose on a multi-ingredient formula’s label against the published research yourself, and you are comfortable paying a premium for that transparency plus select-line testing. It is the strongest of the three specifically for pre-workout and other blended formulas where full disclosure matters most.
Choose Momentous if you are a drug-tested athlete who wants a small, curated set of single-ingredient staples with consistent NSF Certified for Sport coverage and minimal blend complexity to evaluate. Choose Thorne if you want one trusted, NSF-tested, TGA-audited source across a broad catalog — a daily multivitamin, a mineral, and a sports-nutrition product — rather than sourcing each category from a different brand.
Who should skip all three: a non-tested buyer who has already picked a single plain ingredient — creatine monohydrate is the clearest example — and is optimizing purely for cost per gram. The testing premium across all three brands buys real, checkable verification; it does not buy a functionally different creatine molecule than an uncertified generic tub.
Where All Three Share the Same Weakness
None of the three brands makes their least-evidenced product categories more effective simply by testing or disclosing them. A fully disclosed, NSF Certified for Sport fat burner or general “wellness” blend is still a product whose underlying ingredients have limited evidence for meaningfully changing outcomes on their own — certification confirms what is in the bottle, not that the formula works as marketed.
A second shared limitation: none of the three is meaningfully cheaper than the others once you compare like-for-like products at the same dose. Brand loyalty within this certified tier is mostly a question of catalog breadth, product philosophy, and which specific formulas you actually want, not a price difference worth chasing.
Quick Take: Which One to Buy
Quick Take: pick Transparent Labs for maximum label transparency on multi-ingredient sports formulas, Momentous for the tightest, most consistently NSF-tested single-ingredient staples if you are drug-tested, and Thorne if you want one certified source spanning sports nutrition and general health. If you have already decided you only need one plain commodity ingredient and are optimizing for price, skip all three and buy the uncertified generic version instead.
