Best Psyllium Husk Supplements 2026: Cost per Effective Dose
Top pick for Psyllium Husk: NOW Psyllium Husk Powder, Organic (12 oz) — 7g per 1 tbsp (9 g), Non-GMO Project Verified, USDA Organic, $0.37/day. Our pick.
All Psyllium Husk Supplements Compared
Psyllium is bought in three formats that are not interchangeable by weight: whole husk, finer powder, and capsules. The catalog spans 500 mg to 7,000 mg per serving, and that gap is mostly format — matching a single 5 g powder scoop with 500 mg capsules takes roughly ten capsules, which is why the capsule versions look cheap per serving and are not. Take any psyllium with a full glass of water. This page assumes psyllium is already your choice; if you are still deciding between fibre types, inulin, wheat dextrin and methylcellulose compared is the page that answers that.

Registry check · Psyllium Husk
Does anyone independently verify Psyllium Husk supplements?
1 of the 7 Psyllium Husk products on this page is confirmed in NSF/ANSI 173: Konsyl Daily Psyllium Fiber Powder (19 oz). Konsyl Daily Psyllium Fiber Powder (19 oz) does not show the mark on the listing, so the table’s certification column, which repeats the listing, does not show it either. For the others, the listing may name a certification, but we did not find it in a public registry — that is not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the Psyllium Husk dose column either way.
The 7 products on this page checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What Psyllium Husk labels show
Priced per day, these psyllium husk products run $0.05 to $0.37 — a 7.4× gap between the cheapest and dearest psyllium husk here, across 5 brands.
Which row that favours is not obvious: NOW Foods NOW Psyllium Husk Caps, 500mg (500 Veg Capsules) is cheapest per serving at $0.05, but its serving sits below the median here, so part of that price gap is simply a smaller capsule.
