Bulk Psyllium Husk Powder for Supplement and Food Manufacturing
Psyllium husk powder is a milled fiber made from the seed husk of Plantago ovata Forssk., a plantain species grown mainly in western India. It is sold as whole husk flakes or as powder, in purity grades from 85% to 99%. Buyers compare lots by purity, swell volume in water, and mesh size. We supply it in bulk to supplement brands, contract manufacturers, bakeries, and food formulators. You can request testing documents and samples on the quote form.
A seed husk fiber that is easy to grade and test
Psyllium husk is sold on a short list of measurable properties. Purity, swell volume, and mesh tell you most of what you need to compare lots. The rest of the spec covers moisture, ash, metals, and microbes.
Purity grades
Purity is the share of clean husk in the lot. Common grades are 85%, 95%, 98%, and 99%, and the rest is counted as light extraneous matter, such as 1% at the 99% grade.
Swell volume
Psyllium takes up water and sets into a thick gel. Specs state a minimum swell volume, and in one supplier's grade table it rises from 35 mL per gram at 85% purity to 70 mL per gram at 99%.
Whole husk or powder
Whole husk is sold as light, thin flakes, while powder is milled to about 40 to 100 mesh. Finer powder thickens faster in liquid, so the form changes how a recipe behaves.
Dietary fiber on the spec
Supplier specs list total dietary fiber at NLT 70%, measured by an AOAC enzymatic gravimetric method. Some specs also split it into soluble and insoluble fiber, so ask for both if your label math needs them.
One main growing region
Plantago ovata is grown mainly in western India. Ask for the country of origin and the processing site on every lot, so your records match the bag.
Pale color, little taste
Good husk is light beige to off white, with almost no taste or odor. That keeps it in the background of flavored drink mixes and baked goods.
Where formulators use psyllium husk
Psyllium husk fits dry formats and baked goods where water and set time can be planned, including:
- Capsules
- Single ingredient powders
- Powdered drink mixes
- Stick packs and sachets
- Breads, crusts, and baked goods
- Cereals and granola
- Nutrition bars
- Private label programs
Psyllium thickens fast once wet. In drink mixes, expect the liquid to set within minutes, and in baking, adjust water and rest time to the form you buy. Retest your recipe when you switch between whole husk and powder or change mesh.
What to check before you buy psyllium husk
Two lots sold as 99% psyllium can differ in how purity is defined, how swelling is measured, and how clean the husk is. Review these points together, and ask for lot documents before you approve a supplier.
Purity and its basis
Ask how purity is defined. A good spec ties it to a maximum for light extraneous matter, such as 1% for a 99% grade, and also reports heavy extraneous matter.
Swell volume with method
Ask for the swell volume, its unit, and the method. Listings mix mL per gram with other units, so compare lots only on the same test.
Form and mesh
Confirm whole husk or powder and the screen size, for example NLT 95% through 60 mesh, or a 100 mesh powder. Mesh changes how fast the powder sets in your process.
Microbial results
Husk is a raw farm crop, and microbial limits differ tenfold between suppliers. Ask for total aerobic count, yeast and mold, and pathogen results, and ask how the lot was processed to meet them.
Finished label notices
Federal rules at 21 CFR 101.17(f) set a NOTICE about adequate liquid and choking for certain foods made with dry psyllium husk. Plan label space for a fluid statement, and have your regulatory adviser set the wording.
Dust at your plant
Fine psyllium dust is a known workplace sensitizer. Ask for the safety data sheet, and plan dust extraction and respiratory protection before the first delivery.
Swell check: A quick swell test at receiving catches grades that were mixed up. Weigh a set amount into water, wait the stated time, and read the settled volume. Use the supplier's method and unit, so your number matches the COA.

Quality standards for psyllium husk
Psyllium husk has its own USP monograph, and EU pharmacopoeial grades follow the European Pharmacopoeia text for ispaghula husk. The USP tests cover identity, swelling, cleanliness, and microbes, so buyers can compare lots on one basis.
USP Psyllium Husk monograph
The USP defines psyllium husk as the cleaned, dried seed coat of Plantago ovata Forssk., separated from the seed by winnowing and threshing. It may be whole or powdered. The same monograph also admits Spanish or French psyllium, Plantago arenaria. So the Latin name on the COA tells you which species you bought.
Swell volume by the USP method
The USP test places 3.5 g of husk in a USP test solution, made up to 500 mL in a stoppered cylinder. The cylinder is shaken every 30 minutes for 8 hours, then left to settle for 16 hours. Powdered husk must reach NLT 40 mL per g, and whole husk NLT 35 mL per g.
Cleanliness limits
Light extraneous matter is floated off in trichloroethylene, dried, and weighed, with a USP limit of NMT 5%. That limit fits a 95% grade, so a 99% grade is a tighter commercial spec. Insect fragments, including mites and psocids, are capped at 400 per 25 g for powder and 100 for whole husk.
Ash, water, and microbes
The USP sets total ash at NMT 4.0%, acid insoluble ash at NMT 1.0%, and water at NMT 12.0%. Combined yeasts and molds must not exceed 1,000 cfu per g, and Salmonella and E. coli must be absent. The monograph asks for well closed containers, secured against insect attack.
How identity is confirmed
Mounted in cresol, husk cells show as polygonal prisms with 4 to 6 straight or slightly wavy walls. Mounted in alcohol and then wetted, the mucilage in the outer cells swells fast and dissolves. The gel forming fraction is an arabinoxylan, about 74.6% xylose and 22.6% arabinose on a molar basis. A sugar profile can back up microscopy when a powder is very fine.
Contaminant checks to build on
USP <2232> component limits, such as 0.5 µg/g for lead and cadmium, assume an intake of up to 10 g a day. Fiber products can go above that, and then the total micrograms per day must stay within each permitted daily exposure (PDE). EU buyers also ask for ethylene oxide and 2-chloroethanol results by GC-MS/MS, which labs quantify down to 0.01 mg/kg.
Sourcing and processing practices for psyllium husk
Most quality differences in psyllium start at the cleaning line and in storage. These points give QA teams specific questions to ask and records to keep.
Ask how purity is reached
Husk is parted from seed by repeated milling and sieving, then cleaned by gravity separation and air classification. Destoners take out heavy mineral matter. Ask which steps the plant runs and how often it checks purity during a run. The grade, from 85% to 99%, depends on how far this cleaning goes.
Know the microbial control method
Some grades are steam sterilized and state no irradiation and no ethylene oxide. Gamma irradiation at 25 kGy has been shown to change how psyllium gels in water. Ask which method was used on your lot and keep the statement in your file. Rerun your own gel and set time checks if the method changes.
Ask about fumigation and insects
Stored husk may be fumigated against insects. One supplier sheet lists aluminum phosphide with carbon dioxide in Europe and methyl bromide elsewhere. Ask whether your lot was fumigated, with what, and when. Tighter commercial sheets cap insect fragments at 100 per 25 g, against the USP limit of 400 for powder.
Check field cross contact
Psyllium can share fields with other seed crops. One European spec warns that sesame and mustard may be present for that reason. The statement came from a risk assessment, not a test. Ask for your supplier's allergen assessment, and decide whether you need lot testing for sesame.
Match species and units on every document
Spec sheets sometimes carry the wrong Latin name or unit. Check that the species reads Plantago ovata, or Plantago arenaria if you chose it. Check that swell volume reads mL per g and names its method. Ask for a corrected sheet before you approve the supplier.
Formulator tips for psyllium husk
Use these points when you set fill weights, fiber declarations, and incoming tests. Most figures below come from the USP monograph and published supplier sheets.
- Plan capsule fill from bulk density. One 40 mesh powder sheet states NLT 0.60 g/mL, and another lists 0.30 to 0.60 g/mL. So 1 g of powder needs about 1.7 to 3.3 mL of fill volume.
- Base the fiber line on a measured total dietary fiber result, not on the purity grade. Supplier data run from 85.2 to 90 g of fiber per 100 g of husk, so a 99% grade is not 99% fiber.
- Tell your lab the sample is psyllium. The standard AOAC 991.43 fiber method struggles to filter viscous psyllium digests. A published fix adds sonication and high speed centrifugation before filtration.
- Use the full USP swell method when you compare a lot with USP limits. It takes 24 hours, so a quick check at receiving only screens for mix ups.
- Do the metals math at your real intake. At 10 g of husk a day, lead at 1.0 ppm gives 10 µg, twice the USP <2232> PDE of 5 µg. A lead limit of 0.5 ppm keeps 10 g a day at the PDE.
- Check protein as a purity cross check. One grade table allows NMT 3.0% protein at 85% and 95% purity, and NMT 2.0% at 98% and 99%. A result above the grade limit can point to seed fragments.
- Set an incoming test plan. Run microscopy identity, swell volume, light extraneous matter, and microbial counts on every lot. Add lead by ICP-MS on every lot, since intakes are high, and ethylene oxide for goods bound for the EU.
Helping shoppers read a psyllium label
Brands and their customer service teams field the same label questions again and again. These answers stick to what the ingredient is and how it is labeled.
What the label line means
A label may read psyllium husk (Plantago ovata) (husk) or psyllium seed husk. Ispaghula, isabgol, and blond psyllium are other names for the same plant. The husk is the thin seed coat, so whole psyllium seed is sold as a separate item.
Why some labels show a NOTICE
Some psyllium foods carry a statement that starts with NOTICE in capital letters. FDA rules require it on certain foods made with psyllium husk, so it is a standard label element. Customer service teams can point shoppers to that panel when they ask about it.
Independent quality programs
Programs such as the USP Dietary Supplement Verification Program and NSF/ANSI 173 certification check finished products against their labels and contaminant limits. The USP also publishes a monograph for psyllium husk itself, with the swelling and cleanliness tests described above.
Normal look, texture, and home storage
Good husk is pale buff, sometimes with a slight pink tinge, with a faint odor and little taste. It thickens within minutes in liquid, which is normal. Keep the container tightly closed in a dry place, because husk picks up moisture and clumps.
Storage and handling for bulk psyllium husk
Psyllium keeps well when it stays sealed and dry. Its fine dust needs the same controls you use for other sensitizing powders, so plan handling before the first delivery.
Keep it sealed and dry
Psyllium picks up moisture from the air and can clump or set. Close the inner liner after each use, press out the air, and keep bags off the floor in a dry room.
Control dust at each station
Psyllium dust is a known workplace sensitizer. Use local exhaust at tipping, sieving, and blending points, and keep lids on mixers while they run.
Respiratory protection
Give staff who open bags or tip powder respiratory protection suited to the dust level, plus eye protection. Follow the safety data sheet and your own industrial hygiene plan.
Clean up and rotate stock
Pick up spills with a vacuum or a damp method rather than dry sweeping, and dry wet floors at once, since wet psyllium turns slippery. Record lot numbers and retest dates, and use older lots first.
Psyllium husk buyer FAQ
Quick answers to the questions procurement and quality teams ask most.
What does 99% purity mean for psyllium husk?
It means at least 99% of the lot is clean husk, with no more than about 1% light extraneous matter. The 95% and 85% grades allow more. Purity tends to track swell volume, so check both on the COA.
What is the difference between whole psyllium husk and powder?
The difference is particle size. Whole husk is light, thin flakes, while powder is milled to about 40 to 100 mesh and thickens faster in liquid. Pick the form that matches your process, and retest recipes when you switch.
What is swell volume?
Swell volume is the space one gram of husk takes up after soaking in water for a set time. Higher purity lots usually swell more. Compare suppliers only when they use the same method and unit.
Where is psyllium husk grown?
Plantago ovata is grown mainly in western India. Ask for the country of origin and the processing site for each lot. The country of origin for each lot is provided with your quote.
Does a finished psyllium product need a label notice?
Plan for one. FDA rules at 21 CFR 101.17(f) require a NOTICE statement on certain foods made with dry or incompletely hydrated psyllium husk. Your regulatory adviser decides whether it applies and sets the wording.
How should a plant handle psyllium dust?
Handle it as a fine plant dust that needs control. Use local exhaust at tipping and blending points, keep mixers closed, and follow the safety data sheet for protective equipment.
Does USP grade psyllium husk mean 99% purity?
No. The USP monograph allows up to 5% light extraneous matter, which fits a 95% grade. A 99% grade, with NMT 1% light extraneous matter, is a tighter commercial specification. Ask for the purity grade and the USP test results on the same COA.
What documents can I get with an order?
A certificate of analysis (COA) and a specification sheet ship with every order. An allergen statement and a safety data sheet may also be available, depending on the lot in inventory. Contact us to request them.
