Best Beta-Alanine (2026): Cost Per Gram, CarnoSyn vs Generic
Informational summary — not medical advice. This page ranks product value; on what beta-alanine does, see the dosage guide.
Beta-alanine is one molecule — so the "best" one is the cheapest verified one, and since you take 4–6 g/day for weeks, cost per gram matters. A 4 g loading dose spans ~12x across brands ($0.16 to $1.92). Powder wins; CarnoSyn is the same molecule as generic; the priciest items are sustained-release/liposomal formats. Top pick: BulkSupplements Beta-Alanine Powder (500 g).

The one-line takeaway The cheapest here (BulkSupplements, $0.16/4g) and the priciest (Thorne, $1.92/4g) contain the same beta-alanine. Pay more only for capsules, a sustained-release format (real tingle reduction), or a sport certification — never for "better" beta-alanine, which doesn't exist.
The awards
Pure powder at the cheapest verified cost per gram, third-party tested. Since you take 4-6 g/day for weeks, this is the rational buy — chemically identical to the CarnoSyn brands that cost more.
The patented CarnoSyn substrate used in most of the research, from a mainstream brand, still cheap per gram in a 250-serving tub. Worth it if you specifically want the studied ingredient — just know it's the same molecule.
Sustained-release CarnoSyn tablets, NSF Certified for Sport — the tingle-reducing, drug-test-safe pick. Priciest per gram, but the SR format genuinely blunts paresthesia (not a gimmick).
Generic beta-alanine capsules if you won't measure powder — but a 4 g dose is ~5 capsules, so it costs several times the powder per gram.
Every product compared, by cost per gram
Sorted cheapest-first. "Cost per 4 g dose" uses the low end of the 4–6 g/day clinical loading range so brands with different serving sizes compare fairly. Full data is a public CC BY JSON file.

Frequently asked questions
What is the best beta-alanine supplement?
The cheapest verified one, since it's a single molecule and you take 4–6 g/day for weeks. Best overall: BulkSupplements powder. NOW Sports uses CarnoSyn (same molecule, still cheap); Thorne SR is the sustained-release, NSF-Sport pick.
Is CarnoSyn better than generic beta-alanine?
Not chemically — beta-alanine is beta-alanine, and no trial shows CarnoSyn beating equal-purity generic at the same dose. CarnoSyn's edge is regulatory documentation, purity, being the studied substrate, and an SR format. Dose matters far more than brand.
Powder, capsules, or sustained-release?
Powder is far cheaper per gram (a 4 g dose is 5+ capsules). Choose capsules only if you won't measure. SR tablets cost the most but genuinely reduce the tingle by blunting the blood spike — legitimate, but not more effective for carnosine.
