NOW Psyllium Husk Powder, Non-GMO Review
NOW Psyllium Husk Powder is the value champion of this list, and it's not close. If you don't need flavoring and you're willing to stir a scoop into water, it delivers pure, Non-GMO, lab-checked psyllium for the lowest cost per gram of actual fiber here — there's simply no cheaper honest way to take this supplement. The fiber is identical to what's inside the branded canisters; what you skip is the orange flavor, the doctor-recommended halo, and a few cents of convenience. NOW's in-house QC is among the most consistent in the industry, which is what makes this the value pick rather than merely the cheap one. The only real trade-off is grit: plain unflavored husk has no taste masking. We mixed it, checked the label against the panel, and ran the per-gram math. Here's the full breakdown.

Soluble-fiber dose + form fit30%9/10
~4 g of pure psyllium per scoop and fully dose-flexible — one scoop covers regularity (Ashraf 1995 territory), and you can build to two-plus scoops for the Anderson 2000 ~10 g/day cholesterol range. A touch lower per scoop than Konsyl's ~6 g (#2), so a cholesterol dose takes a little more powder, but the flexibility is excellent.
Purity + label honesty25%9.5/10
100% pure psyllium husk, Non-GMO, with no sugar, sweetener, flavor, color, or filler — clean, single-ingredient, exactly as labeled. Nothing to flag. The Non-GMO verification is a small extra credit on top of an already honest label; the only 'cost' of this purity is texture, scored under mixability.
Cost per effective gram20%10/10
The value engine and the reason this is the budget pick. ~$0.13 per ~4 g serving is the lowest cost per gram of actual psyllium on the list — well under flavored branded powders and a fraction of the per-effective-gram cost of capsules. There is no cheaper honest way to take this fiber.
Third-party testing + manufacturing15%9/10
NOW's in-house QC labs are among the most consistent in the industry, the facility is GMP-certified, and the raw material is identity-tested and Non-GMO. Unusually strong testing pedigree for a budget product — for an imported agricultural fiber where identity and contaminants matter, this is what makes it the value pick, not just the cheap one.
Mixability + adherence10%7/10
The trade-off for the price. Plain unflavored husk is gritty with no taste masking, so you have to be okay drinking psyllium-in-water. It mixes fine and is dose-flexible, but it's not a pleasant flavored drink — Metamucil (#1) wins clearly on palatability, and finely-ground organic husk (#5) is smoother in smoothies.

Marketing claims vs. reality
Verified
“Non-GMO.”
NOW labels this husk Non-GMO and runs identity testing on its raw materials through its in-house QC labs. A verifiable, modest extra-credit claim on an already clean single-ingredient product.
Verified
“Supports regularity and digestive health.”
Core, well-evidenced psyllium effect — the water-holding gel softens and bulks stool (Ashraf 1995, PMID 8824651) and normalizes both constipation and loose stool. Fully delivered by pure husk at a regularity-sized scoop.
Partial
“Supports healthy cholesterol levels.”
Real but dose-dependent. Anderson 2000 (PMID 10648260) lowered LDL ~7% at ~10.2 g/day — so the cholesterol benefit requires building NOW up to roughly two-plus scoops daily and taking it consistently. At a single regularity scoop you get the digestive benefit, not the lipid effect.
Verified
“Made with NOW's quality and testing standards.”
NOW's extensive in-house QC labs and GMP-certified manufacturing are a well-documented, genuine industry strength — and the main reason this budget husk is trustworthy, not just cheap.
What our test actually found
01Same fiber as the branded canisters, a fraction of the price
The single most useful thing to know: the psyllium husk in this bag is the same fiber as in Metamucil (#1) or Konsyl (#2) — the trials that validate psyllium are about the fiber, not the label. NOW strips out the flavoring and the brand premium and sells you the active ingredient at the lowest cost per gram on the list. If you're comfortable stirring plain husk into water, you're buying identical efficacy for far less money.
02The QC is why it's the value pick, not just the cheap pick
Plenty of bulk husk is cheap; what separates NOW is that it's cheap and trustworthy. Psyllium is an imported agricultural product, so identity and contaminant testing genuinely matter, and NOW's in-house QC labs and GMP facility are among the industry's most consistent. That combination — lowest price plus real testing pedigree — is exactly what earns it the 'best value' badge rather than a budget-with-an-asterisk caveat.
03Dose-flexibility is the quiet advantage of unflavored bulk
Because there's no fixed flavored serving, you dose precisely to your goal: one scoop (~4 g) for regularity, build to two-plus scoops for the Anderson 2000 ~10 g/day cholesterol range, anywhere in between for satiety. Flavored pre-measured products lock you into their dose; bulk husk lets you titrate. Start at half a scoop and build over a week or two to let your gut adapt, splitting larger totals across meals.
04Grit is the price of the price
The honest trade-off is texture. Plain unflavored husk has no taste masking, so it goes down gritty in water — fine for someone who just wants cheap, effective fiber, unpleasant for someone who wants a nice drink. If palatability is the difference between taking it daily and quitting, pay up for Metamucil (#1); if you'll happily drink husk-in-water, NOW's grit is a small price for the lowest cost per gram here.
05The water rule beats the bargain
No price is worth skipping the hydration caveat. With unflavored bulk powder it's easy to under-measure both the husk and the water — be deliberate: add the scoop to a full glass of water, stir, and drink promptly before it gels. Taken dry or under-hydrated, psyllium can swell and choke or obstruct (McRorie 2015, PMID 25623333). And anyone with swallowing difficulty or a history of gut narrowing should choose a different kind of fiber entirely.
Pros & cons, no sugar-coating
Pros
- Lowest cost per gram of actual psyllium on the list — pure husk with no brand or flavor markup
- 100% pure, Non-GMO psyllium husk — clean single-ingredient label, dose exactly as much as your goal needs
- NOW's in-house QC labs are among the most consistent in the industry, with GMP manufacturing and identity testing
- Dose-flexible powder scales from a small regularity scoop up to the ~10 g/day cholesterol range
- Decades of household-brand trust at a genuine budget price
Cons
- Plain unflavored husk is gritty with no taste masking — you have to be okay drinking psyllium in water
- ~4 g per scoop is a touch lower than Konsyl's ~6 g (#2), so a cholesterol dose takes a little more powder
- 12 oz bag is smaller than the bulk organic bags (#8) for heavy daily users
The value champion of the list.
NOW Psyllium Husk Powder is the pick for anyone whose first question is price. If you don't need flavoring and you're willing to stir a scoop into water, it delivers pure, Non-GMO, lab-checked psyllium for the lowest cost per gram here — there's no cheaper honest way to take this fiber, full stop. The fiber is identical to the branded canisters, NOW's QC is genuinely strong, and the powder is dose-flexible from a regularity scoop up to a full cholesterol dose. The only things you give up are taste and a little dose density. Versus Metamucil (#1) you lose the flavored, doctor-trusted, easy-to-drink experience that drives adherence — if grit would make you quit, pay the premium there instead. Versus Konsyl (#2) you get ~4 g per scoop rather than ~6 g, so a cholesterol dose takes a bit more powder. And if USDA Organic is non-negotiable, Organic India (#4) or Viva Naturals (#5) are the picks. But for a no-nonsense, lab-checked daily fiber habit at the best price on the shelf, this is the one to buy — taken, as always, with a full glass of water.
