Psyllium husk for supplements and psyllium for pet food are bought as the same plant fibre but to different specifications. Moringa for supplement brands and ashwagandha for supplement manufacturers are bought as dried, milled plant material with defined colour, particle size and test results. Herbs for tea blenders are a cut-and-sifted product where appearance matters.
This guide stays at the raw-ingredient level. It covers what to specify and test, not what the finished product may claim, which is a matter for your regulator and legal adviser.
Psyllium husk for supplements and for pet food
Psyllium husk is sold by purity percentage and mesh. For supplement use, makers usually want a high-purity husk with low foreign matter, tight microbiology and a stated swelling capacity. For pet food, purity requirements can be lower, but contaminant and microbiology limits still apply. The grade question is covered in whether psyllium is used in pet food and what grade is needed.
The pet food buyer should also ask about the animal-feed rules in the destination market. Feed law differs from food law, so check the permitted ingredients and the documentation your authority expects before you specify the husk.
Moringa for supplement brands
Moringa leaf powder is judged on colour, particle size, moisture, microbiology and heavy metals. Drying method and temperature decide whether the powder is bright green or dull brown, as explained in how moringa leaf is dried and what affects its colour.
Leaf powder is a fine, light material that cakes in damp conditions, so pack it in sealed liners. Ask for a certificate of analysis for each lot, with pesticide residue and heavy metal results from an accredited laboratory.
Ashwagandha for supplement manufacturers
Ashwagandha is usually bought as dried root, root powder or a standardised extract. At the raw-powder level, you specify the plant part, particle size, moisture, microbiology and a marker compound test. What to ask for on the marker is explained in the withanolide content ashwagandha root powder should have.
The regulatory position of ashwagandha varies. Some European countries restrict or limit it, and others permit it with conditions. Confirm the position with the national authority in your market before you place an order, and read the EU novel food rules for Indian botanicals.
Herbs for tea blenders
A tea blender cares about cut size, colour, aroma and the absence of dust and stalks. Ask for a sample cut to your size and for the sieve analysis, and check that the herb has not been coloured or flavoured. Microbiology and pesticide residue limits for herbal infusions are tighter than many suppliers expect, so state them in the contract.
Whichever herb you buy, ask for the botanical name on the certificate, such as Moringa oleifera or Withania somnifera. A common name alone does not tell you which plant, or which part of it, is in the bag. Ask also for the harvest year and the batch code, so that any later complaint can be traced to a field and a drying lot.

We find and audit manufacturers, check samples and documents, and have lots tested to your specification before you ship. Cost differences between suppliers come from material grade, processing and testing, and only a written spec produces a comparable quote.
