Here’s exactly what each grade means, drawn directly from manufacturer specifications, so you can match the right form to the right use case.
1. Whole Colostrum Powder — 20% IgG (Regular & Instantized)
Whole Colostrum Powder is colostrum in its most natural state — nothing added or removed except water. It contains 60% protein and 20% IgG, making it the full-spectrum, least-processed option among the powder grades.● Regular: off-white to creamish colour, partially soluble, supplied in 20 kg drum packs.
● Instantized: same 60% protein / 20% IgG specification, with 0.1% of a natural source added to make it highly soluble and free-flowing — useful when the powder needs to mix cleanly into a beverage or ready-to-mix formulation rather than being encapsulated.
Applications: kids and adult formulations, protein formulations, tablet making, skin care formulations, animal feed formulations, and animal skin care formulations.
Whole colostrum powder is generally the right starting point for buyers who want the broadest nutrient and bioactive profile — including the natural fat fraction — rather than a concentrated IgG extract.
2. Skimmed Colostrum Powder — 30% IgG (Regular & Instantized)
Skimmed Colostrum Powder – 30% IgG removes most of the fat fraction to concentrate immunoglobulins further. Specification: minimum 70% protein, 30% IgG, and fat greater than 5%.● Regular: off-white to creamish colour, partially soluble, 20 kg drum pack.
● Instantized: identical 70% protein / 30% IgG / >5% fat specification, processed to be highly soluble.
Applications: the same range as whole colostrum powder — kids and adult formulations, protein formulations, tablet making, skin care formulations, and animal feed/skin care formulations — but at a higher IgG density per gram, which matters for formulators working to a specific IgG-per-serving target.
3. Skimmed Colostrum Powder — 40% IgG (Regular & Instantized)
Skimmed Colostrum Powder – 40% IgG is the most concentrated commercial grade in Biostrum’s range: minimum 70% protein, 40% IgG, and fat greater than 5% — the same protein and fat range as the 30% IgG grade, but with immunoglobulin content pushed higher through further skimming and concentration.● Regular: off-white to creamish colour, partially soluble, 20 kg drum pack.
● Instantized: same 70% protein / 40% IgG / >5% fat specification, highly soluble.
Applications: identical use range — kids and adult formulations, protein formulations, tablet making, skin care formulations, animal feed formulations, and animal skin care formulations — but this is the grade to reach for when a formulation is built specifically around maximizing IgG delivery per dose, such as premium immune-support SKUs.
4. Whole Colostrum Granules & Skimmed Colostrum Granules
Whole & Skimmed Colostrum Granules solve a different problem: they aren’t meant for direct mixing but for capsule and tablet manufacturing. Whole Colostrum Granules carry the same 60% protein / 20% IgG specification as whole colostrum powder, retaining colostrum in its natural state — but with a key structural difference: they’re high in density, which makes them mostly suited for capsule filling and tablet manufacturing rather than powder-format use. They’re off-white to creamish in colour and supplied in 25 kg and 35 kg drum packs. Skimmed Colostrum Granules are offered as a companion variant for buyers needing the higher-IgG skimmed profile in the same dense, tableting-suited granule form.If you’re a brand manufacturing your own colostrum capsules or colostrum tablets rather than buying finished product, granules — not standard powder — are typically the correct raw material request to make to your manufacturer.
How to Choose the Right Bovine Colostrum Powder Grade
| Need | Recommended Form |
| Full-spectrum nutrient profile, general wellness use | Whole Colostrum Powder – 20% IgG (Regular) |
| Mixable into beverages/ready-to-mix products | Whole or Skimmed Colostrum Powder – Instantized |
| Higher IgG concentration per dose | Skimmed Colostrum Powder – 30% or 40% IgG |
| Maximum commercial IgG concentration | Skimmed Colostrum Powder – 40% IgG |
| Manufacturing your own capsules/tablets | Whole or Skimmed Colostrum Granules |
Sourcing Bovine Colostrum Powder from Manufacturers in Indi
When evaluating colostrum powder manufacturers in india for any of these grades, the specification sheet is your first checkpoint — protein %, IgG %, fat content, solubility, and pack size should all be explicitly stated, not just implied by marketing copy. A manufacturer offering the full grade range (20%, 30%, 40% IgG, regular and instantized, plus granules) generally indicates broader in-house processing capability than one offering a single generic “colostrum powder” SKU. This also matters when comparing colostrum suppliers in india more generally — a suppliers who is really a reseller may only carry one or two of these variants, sourced from a third party, rather than the full manufacturer-direct range.Buying Bovine Colostrum Powder Online
For individual buyers rather than bulk formulators, searching colostrum powder online will surface all of these grades under various listings. Before ordering, confirm which specific variant (whole vs. skimmed, IgG%, regular vs. instantized) is being sold — “colostrum powder” alone doesn’t tell you the potency, and pricing across these grades should reflect the IgG concentration difference.From Raw Powder to Finished Products
Most individual consumers won’t buy 20 kg drums of raw powder — they’ll want a finished, ready-to-take product. Biostrum’s Colostrum Capsules (350 mg and 500 mg) and Colostrum Tablets — a 1500 mg chewable tablet containing 500 mg colostrum, available in Vanilla, Strawberry, Chocolate, and Mango — are made using this same underlying powder and granule range, giving retail buyers a standardized, easy-to-use dose without handling bulk powder directly. These colostrum chewable tablets are formulated for both kids and adults.For related specialty ingredients, Lactoferrin 95% — a lactoferrin powder isolated to over 95% purity — is manufactured alongside the colostrum powder range and is a common companion sourcing request for brands building a broader immune-support or infant-nutrition line, particularly relevant for anyone seeking a lactoferrin supplement in india from the same quality-controlled source.
