NOW Sports BCAA Powder rounds out the list as the bare-bones budget bulk option from a manufacturer with decades of GMP credibility. It's a correct free-form 2:1:1 (L-leucine, L-isoleucine, L-valine) at a low cost per gram, with nothing added — the no-frills choice for cost-conscious daily use from a brand you can trust. The honest knock is dose and mixability. At roughly 3 g BCAA (~1.5 g leucine) per scoop it's the lightest serving on the list, so you'll likely double-scoop to reach an effective leucine dose, and free-form powder is bitter and clumps. It's the pick only if rock-bottom price and a trusted brand outweigh dose convenience; the unflavored powders above (#4, #6, #7) deliver a fuller per-scoop dose for similar money. As always, the category caveat applies — on adequate protein, this is a training tool, not a growth driver. Here's the breakdown.

Read the complete BCAA guide →A correct free-form 2:1:1 ratio, but the per-scoop dose is light — about 3 g BCAA (~1.5 g leucine), below the ~2.5 g leucine threshold for triggering muscle protein synthesis (Jackman 2017). You'd want a roughly double scoop to reach an effective dose, which the other powders deliver in one. The ratio is right; the standard serving is the weakest among the powders, capping this axis at 6.5.
Nothing added — pure free-form BCAA, no glutamine, electrolytes, or EAAs. Consistent with the other bare-bones powders and standard for a budget bulk product. On an axis rewarding extras it lands at the midpoint. For built-in extras you need Xtend (#1) or Transparent Labs (#2); NOW is aminos only.
NOW Foods is GMP-quality assured with a long, credible manufacturing reputation, giving reasonable confidence in label accuracy. But there's no NAMED NSF Certified for Sport or Informed Sport certification — the standard for tested athletes. Credited for NOW's GMP credibility, held below the certified pick (Thorne #3). Consistent with the other uncertified picks.
$0.24 per ~3 g scoop in a large bulk tub — a low cost per gram and genuinely cheap headline value from a trusted brand. The asterisk: because the scoop is light, double-scooping to an effective dose roughly doubles the real per-effective-serving cost, narrowing the gap with the 5 g powders. Strong on cost-per-gram, merely competitive on a dose-matched basis.
Free-form (non-instantized) BCAA powder mixes poorly — it clumps and floats rather than dissolving — and unflavored BCAAs are bitter. Workable only when stirred vigorously into a flavored carrier; unpleasant straight in water. Scored at 6.0, at the lower end with the other unflavored powders and below the instantized ON (#4), which mixes more easily.
“Free-form BCAAs in a 2:1:1 ratio.”
Accurate — NOW provides free-form L-leucine, L-isoleucine, and L-valine in a 2:1:1 ratio. The form and ratio are exactly as stated. 'Free-form' is honest (and explains the poorer mixing versus instantized powders), and the 2:1:1 is the standard studied ratio.
“Supports muscle recovery and endurance.”
Supported but modest, condition-dependent, and contingent on an effective dose — which NOW's light scoop may not reach without doubling (VanDusseldorp 2018, PMID 30275356; Fouré & Bendahan 2017, PMID 28934166; Blomstrand 2006, PMID 16365096 for the endurance/enzyme angle). Honest as a modest aid at an adequate dose; overstated at the single light scoop.
“GMP-quality assured.”
True — NOW Foods manufactures in GMP-certified facilities with a long, credible quality-control record. This is a genuine quality assurance and the claim holds. Note (without making it false) that GMP is not the same as a named NSF/Informed sport certification, which tested athletes need.
“Helps preserve lean muscle while training.”
Partly. BCAAs can support muscle during training at an effective dose, but they trigger rather than complete protein synthesis — full EAAs beat BCAAs (Moberg 2016, PMID 27053525) and the BCAA-alone claim was called 'unwarranted' (Wolfe 2017, PMID 28852372). At NOW's light per-scoop dose and on adequate protein, the muscle-preservation effect is minimal. Defensible at an adequate dose; overstated as labeled.
“Great value BCAA supplement.”
Fair on cost-per-gram — it's a cheap bulk tub. But 'great value' is tempered by the light per-scoop dose: double-scooping to an effective amount roughly doubles the real cost per effective serving, making it competitive rather than clearly best. Accurate as 'low cost-per-gram'; 'great value' depends on accounting for the dose you actually need.
NOW Sports BCAA Powder's real appeal is its combination of a credible, decades-old GMP manufacturer and a low cost per gram. For a cost-conscious buyer who trusts the NOW name and wants a bulk tub of correct free-form 2:1:1 BCAAs, those are legitimate reasons to buy. The BCAAs themselves are exactly what's on the label, and the price per gram is among the lowest on the list. If your priorities are brand trust and cheap bulk, NOW delivers both.
The single biggest thing to understand: NOW's standard scoop is only ~3 g BCAA (~1.5 g leucine), the lightest on the list and below the ~2.5 g leucine threshold for triggering muscle protein synthesis. To get an effective dose you'll want to roughly double the scoop — which the 5 g powders (ON #4, Kaged #6, Naked #7) deliver in a single scoop. This light serving is the main reason NOW ranks at #9 rather than higher; it's correct BCAAs, just under-portioned per scoop.
Because NOW's powder is free-form rather than instantized, it clumps and floats rather than dissolving cleanly, and unflavored BCAAs are bitter on top of that. Straight in water it's a gritty, unpleasant drink. The workable approach is to stir it vigorously into a flavored carrier like a shake or pre-workout. If smooth mixing matters to you, the instantized ON (#4) is a noticeably better experience, and a flavored tub (Xtend #1) better still. Buy NOW knowing you'll be mixing it into something else.
The headline cost-per-gram is genuinely low, but the honest value picture requires accounting for the light scoop. If you double-scoop to reach an effective leucine dose, your real cost per effective serving roughly doubles, which brings NOW in line with — rather than clearly ahead of — the 5 g unflavored tubs that also mix better. It's a fine budget option; it's just not the value slam-dunk the per-gram price alone suggests once you adjust for the dose you actually need.
The category caveat applies with extra force given the small per-scoop dose: on adequate protein, a light scoop of BCAAs adds essentially nothing for muscle growth over food, because a complete protein or full EAA supplies all nine aminos and BCAAs supply three (Moberg 2016; Wolfe 2017). Buy NOW Sports BCAA as a cheap bulk amino tool for fasted or intra-workout use if you value the brand and price — not as a muscle-building strategy. For growth, protein is the purchase that matters.
NOW Sports BCAA Powder is the budget bulk option for a cost-conscious buyer who trusts the NOW name. It's a correct free-form 2:1:1 BCAA at a low cost per gram from a manufacturer with decades of GMP credibility, with no additives. For someone who wants cheap bulk aminos from a brand they trust and doesn't mind a little hassle, it does the job. The limitations are real and they're why it ranks last. The per-scoop dose is the lightest on the list (~1.5 g leucine), so you'll want to double-scoop to reach an effective amount — which roughly doubles your real cost and narrows its value edge over the 5 g powders. Free-form powder clumps and is bitter, so it's a mixer not a sipper, and the instantized ON (#4) mixes more easily for similar money. There's no glutamine or electrolytes, and no named certification (tested athletes → Thorne #3). And the category caveat applies doubly at this light dose — on adequate protein, it adds essentially nothing for growth. Buy NOW Sports BCAA if cheap cost-per-gram and brand trust are what you want, plan to double-scoop it into a shake, and you'll get correct BCAAs for your money.

mTORC1 activation ranked leucine < BCAAs < all nine EAAs — evidence that a complete protein or full EAA outperforms a light-dose pure-BCAA powder like NOW for muscle growth.
Concluded BCAAs alone are 'unwarranted' as an anabolic claim — the reason NOW's muscle-preservation claim is rated partial and protein is the better growth buy.
BCAAs activate post-exercise protein-synthesis enzymes including after endurance exercise — supports NOW's endurance/recovery claim as a modest benefit at an adequate dose.
