Why It Scores 8.3 — And The Label Line Behind Each Number
Form & source (CarnoSyn vs generic)
30% of scoreGeneric beta-alanine rather than patented CarnoSyn — the same molecule, but not the branded research form or its identity testing. NOW's long-standing brand quality lifts its form-and-source standing above the cheaper generics, but on the most heavily weighted axis it still sits below the two CarnoSyn picks.
- Form
- Pure beta-alanine (generic, not CarnoSyn-branded)
- Other ingredients
- None — pure beta-alanine powder
Purity & third-party testing
25% of scoreManufactured and tested in NOW's own GMP-certified facilities — a genuinely strong QC signal, since NOW runs extensive in-house analytical labs and is one of the more transparent large manufacturers. Provenance honesty: this is robust in-house GMP testing, which is a real trust signal but is manufacturer QC rather than a per-batch third-party or NSF Certified for Sport seal.
- Testing
- Manufactured and tested in NOW's GMP-certified facilities
Effective, honest dose
20% of scoreThe honest weak point. The label's serving is a 2,000 mg scoop, which sits below the ~3.2 g/day research dose, so a single scoop under-doses unless you heap it or take ~1.5 scoops. It scores respectably because NOW states the 2 g amount plainly rather than hiding it, but a sub-research serving size is exactly what our methodology marks down.
- Dose
- 2,000 mg per level scoop (below the 3.2 g research dose — take ~1.5 scoops)
Value per effective serving
15% of scoreAt ~$20 for 500 g the tub is cheap, but because you need ~1.5 scoops to reach the research dose the cost per effective 3.2 g serving (~$0.16 per 2 g scoop, more per real dose) lands mid-pack rather than at the bargain-value end. Fair, not the cheapest per effective gram.
- Price
- ~$20 (~$0.16 per 2 g scoop)
Mixability & usability
10% of scoreA standard fine unflavored powder — gritty in plain water, fine in a flavored drink. The one usability wrinkle is that the 2 g scoop forces you to measure a heaped or one-and-a-half scoop to hit the dose, adding a small guesswork step the cleaner 3 g-scoop picks avoid.

Marketing Claims Vs. Reality
Pure beta-alanine powder — single ingredient.
The product is a one-ingredient unflavored powder, consistent with NOW Sports' straightforward single-active labeling. The purity claim is accurate.
Manufactured and tested in GMP-certified facilities.
NOW is well documented for running extensive in-house GMP-certified manufacturing and analytical testing and is unusually transparent for a large brand. The GMP claim is accurate and a genuine trust signal — though it is manufacturer QC, not a per-batch third-party COA.
A 2,000 mg scoop is a serving of beta-alanine.
Labeling a 2 g scoop as the serving understates the effective amount: the research dose is ~3.2 g/day, so a single level scoop is sub-clinical. NOW states the 2 g figure plainly, but a buyer who takes one scoop believing it is a full research dose is under-dosing by roughly a third. Take a heaped or ~1.5 scoop.
Supports high-intensity exercise performance.
True but narrow. Per Hobson 2012 and Saunders 2017 the benefit is modest and concentrated in 1-4 minute high-intensity efforts, and only appears after weeks of daily dosing at the full ~3.2 g — which this product only reaches if you take more than one labeled scoop.
What Our Test Actually Found
A trusted brand and real in-house testing
NOW is one of the most established supplement makers around, running extensive in-house GMP-certified manufacturing and analytical labs, and it is unusually transparent for a large brand. For a buyer who wants a familiar name and documented QC behind a simple amino acid, that reputation is the whole appeal, and it lifts NOW above the anonymous generics on the testing axis.
The 2 g scoop is the catch — do not take it at face value
The single most important thing to know: the label's 2,000 mg scoop sits below the ~3.2 g/day research dose. A buyer who takes one level scoop is under-dosing by about a third and may conclude beta-alanine 'does nothing.' Take a heaped scoop or ~1.5 scoops to actually reach the studied amount. NOW states the 2 g figure honestly, but the serving size itself under-delivers.
Generic form, so it ranks behind the CarnoSyn picks
Like most of the field, this is generic beta-alanine rather than patented CarnoSyn. That is a modest quality-assurance distinction, not a safety concern — but our methodology weights the raw material heaviest, so it keeps NOW behind NutraBio and ProLab despite the strong brand and testing.
Cheap tub, but not the cheapest per effective dose
The 500 g tub is inexpensive at ~$20, but because you need ~1.5 scoops to hit the research dose, the cost per effective 3.2 g serving lands mid-pack rather than at the bargain end. Nutricost and BulkSupplements deliver a full 3 g scoop for less per real dose. NOW's value is 'trusted and affordable,' not 'cheapest per gram.'

Pure beta-alanine from one of the most established GMP supplement makers, in a big 500 g tub at a friendly price. The catch is the serving: a 2,000 mg scoop sits below the ~3.2 g research dose, so take a heaped or 1.5x scoop. Generic rather than CarnoSyn. A safe, well-known, inexpensive choice for buyers who value a trusted brand over the patented form.
NOW Sports is the trusted-name pick: a pure beta-alanine powder from one of the most established, GMP-certified supplement makers around, in a big 500 g tub at a friendly price. The one thing to flag honestly is the dose — the label's serving is a 2,000 mg scoop, which sits below the ~3.2 g used in the studies, so you will want a slightly heaped or one-and-a-half scoop to actually hit the research dose. It is generic beta-alanine rather than the patented CarnoSyn form, too. But for a reputable, tested, inexpensive tub from a name you already know and trust, it is a safe and sensible choice — as long as you dose it up to the research amount rather than taking the 2 g scoop at face value.
A safe, trusted, affordable tub — as long as you dose past the 2 g scoop.
NOW Sports is the trusted-name pick: a pure beta-alanine powder from one of the most established, GMP-certified makers around, in a big 500 g tub at a friendly price, with genuinely strong in-house testing behind it. For a buyer who wants a familiar name and documented QC on a simple amino acid, it is a safe, sensible choice. Two honest flags decide how you use it. First, the dose: the label's serving is a 2,000 mg scoop, which sits below the ~3.2 g used in studies, so take a slightly heaped or one-and-a-half scoop to actually hit the research amount — do not take the single scoop at face value. Second, it is generic rather than CarnoSyn beta-alanine, which keeps it behind the top two picks. Neither is a dealbreaker for the right buyer. Reach the full ~3.2 g/day, split it to tame the tingle, and give it 3-4 weeks.
If This Doesn’t Fit — Try These
01NutraBio Beta-Alanine
In a category where the molecule is identical tub to tub, the right #1 is the one that nails the two things that actually vary: the form and the testing.
03BulkSupplements Beta-Alanine
BulkSupplements is the workhorse value powder, and it does exactly what a single-ingredient supplement should: pure beta-alanine, a clean 3 g scoop that matches the research dose, batch lab-testing in a cGMP facility, at one of the lowest costs per gram you'll find.
05Nutricost Beta-Alanine
Nutricost is the budget value leader: pure, non-GMO beta-alanine in a big 500 g tub, third-party tested in an ISO-accredited lab, at one of the lowest prices per gram you'll find.
Quick Answers
Is the 2 g scoop enough on its own?
No — that is the key thing to know. The research dose is about 3.2 g/day, and NOW's labeled scoop is 2,000 mg, so a single level scoop under-doses by roughly a third. Take a heaped scoop or about one and a half scoops to actually reach the studied amount. NOW states the 2 g figure honestly; you just have to dose above it.
Why does NOW rank above the cheaper generics but below the CarnoSyn picks?
Two reasons. It beats the anonymous generics on brand quality and documented in-house GMP testing, which our methodology rewards. But it is still generic beta-alanine rather than the patented CarnoSyn form, and its scoop under-doses the research amount — so it sits behind NutraBio and ProLab, which lead on form and dose honesty.
Is NOW's in-house testing trustworthy?
It is one of the stronger QC stories among large brands — NOW runs extensive in-house GMP-certified labs and is unusually transparent about it. Keep the framing honest, though: that is robust manufacturer quality control, not a per-batch third-party COA or an NSF Certified for Sport seal. For most buyers it is plenty; drug-tested athletes should look for certified-for-sport batches.
Will it make me tingle?
Possibly, especially once you dose up to the full ~3.2 g. The tingle (paresthesia) is a harmless pins-and-needles flush that fades within an hour. Split your dose into smaller amounts through the day — for example one scoop morning and one later — and it largely disappears.
