NOW Psyllium Husk Powder, Non-GMO Review

Yes — chemically it's the same psyllium husk, just without the flavoring and the brand premium. The active fiber in Metamucil (#1) is psyllium husk; NOW gives you that same Plantago ovata husk, Non-GMO and lab-checked, for a fraction of the per-gram cost. The trials that validate psyllium — regularity (Ashraf 1995, PMID 8824651), IBS (Moayyedi 2014, PMID 25070054), cholesterol (Anderson 2000, PMID 10648260) — are about the fiber, not the brand. What you give up buying bulk is the orange flavor, the doctor-recommended halo, and a pre-measured convenience; what you gain is the lowest honest price per gram on this list.

Scale the scoop to the job. For regularity, ~3-5 g/day (roughly one scoop) is plenty — that's the Ashraf 1995 territory. For cholesterol or satiety, you're aiming at the Anderson 2000 ~10 g/day range, so build up to about two to two-and-a-half scoops a day, split across meals. Start low — half a scoop — and increase over a week or two so your gut adapts and you avoid gas and bloating. The advantage of unflavored bulk powder is exactly this flexibility: you dose precisely as much as your goal needs, no more, no less.

Three buyers, three picks. NOW is the value champion: lowest cost per gram, pure Non-GMO husk, for the person who'll happily stir plain powder into water. Konsyl (#1) is the high-dose pick: ~6 g per scoop versus NOW's ~4 g, so it reaches the ~10 g/day cholesterol range in fewer scoops — worth a small premium if grams matter most. Metamucil (#1) is the flavored, doctor-trusted default: easiest to drink and best for adherence, at the highest per-gram cost. If budget is the constraint and grit doesn't bother you, NOW wins outright.

Strong — it's one of NOW's real differentiators. Psyllium is grown mostly in India and imported, so identity verification and contaminant testing genuinely matter. NOW runs extensive in-house QC labs in a GMP-certified facility and identity-tests its raw materials, and the husk here is Non-GMO. For a budget product that level of testing pedigree is unusual and is a big part of why this is the value pick rather than just the cheap pick — you're getting low cost without giving up the quality gate.

A full glass per scoop (≥250 ml), drunk promptly, with more fluid through the day. This is the one rule that overrides brand and price: psyllium works by swelling into a gel, and taken dry or with too little liquid it can swell in the throat or gut and cause choking or obstruction (McRorie 2015, PMID 25972618). With unflavored bulk powder it's easy to under-measure both powder and water, so be deliberate — add powder to a full glass, stir, and drink before it thickens. Anyone with swallowing difficulty or a history of bowel narrowing should not use psyllium.

It depends on your dose. At a regularity dose of one scoop a day, a 12 oz package lasts a good while and the value is excellent. If you're a heavy daily user targeting the ~10 g/day cholesterol range — two-plus scoops a day — you'll go through it faster, and a bulk organic bag like Anthony's (#7, 1.5 lb) may be better value per gram over time, especially if you also want USDA Organic. For most people starting out, the 12 oz NOW is the right balance of price, freshness, and trust; size up once you know your steady dose.
