Best Colostrum Supplement in Canada (2026): Ranked by Disclosed IgG
Informational summary — not medical advice. Colostrum is a dairy product; anyone with a cow's-milk-protein allergy should avoid it. Its popular benefits are largely unproven (see the evidence); this page ranks product transparency and value, not effectiveness.
The best colostrum is the one that tells you how much IgG you're buying — and most big-name brands don't. IgG (immunoglobulin G) is the active fraction that matters. We rank by disclosed IgG % and cost per gram of actual IgG. Of 3 products in the Canadian catalog, all 3 disclose their IgG, so here we can rank by it directly. Top pick: Energievoll Bovine Colostrum Supplement Powder, 60% IgG. Before you buy, know that colostrum's benefits are largely unproven.

The awards
Minimum 60% IgG, the highest disclosed concentration in the Canadian catalog, and because of that concentration the cheapest per gram of actual IgG here. No named third-party lab, but a specific, disclosed minimum you can hold the brand to.
New Roots Herbal is a Canadian brand; this scoop states 650 mg of IgG directly rather than a colostrum-mass-plus-percentage figure. Mid-priced per gram of actual IgG among the three Canadian options.
Capsules instead of a powder scoop, still disclosing a minimum 30% IgG, and Health Canada has issued it a Natural Product Number — licensed, though not independently (third-party) tested. The lowest concentration and highest cost per gram of IgG of the three, but the easiest to travel with.
Every product compared, per serving
Sorted by cost per gram of IgG (best value first). All three products in the Canadian catalog disclose their IgG, so every row can be priced. Full machine-readable data for the wider catalog is a public CC BY JSON file.
| Product | Form | Colostrum/serving | IgG disclosed | IgG/serving | $/serving | $ per g IgG |
|---|---|---|---|---|---|---|
| Energievoll Bovine Colostrum Supplement Powder, 60% IgG | Powder | 3,000 mg | 60% | 1.8 g | $1.59 | $0.88 |
| New Roots Herbal Bovine Colostrum Powder, 30% Immunoglobulins | Powder | Not stated (650 mg IgG stated directly) | 30% | 0.65 g | $0.73 | $1.12 |
| Herba Colostrum Supplements 500 mg, 30% IgG | Capsule | 1,000 mg | 30% | 0.3 g | $0.60 | $2.00 |
Prices are Amazon.ca buy-box figures as of when we checked ÷ pack serving count; they move. Cost per gram of IgG = ($/serving) ÷ (colostrum g × disclosed IgG %), or ÷ disclosed IgG grams directly where the label states IgG content rather than total colostrum mass.
The value takeaway The cheapest disclosed IgG here is Energievoll Bovine Colostrum Supplement Powder, 60% IgG at about $0.88/g of IgG. The priciest per gram of IgG among the three Canadian options is Herba Colostrum Supplements 500 mg, 30% IgG, at about $2.00/g. Buy the disclosed gram, not the brand. One caveat: the evidence for colostrum's effects is limited, so this ranks value per gram of IgG, not a potency or benefit score.
How to read a colostrum label
- Find a disclosed IgG %, stated as a minimum. "Minimum 30% IgG" is a spec; "up to 30%" or "rich in immunoglobulins" is not.
- Check for batch or third-party lab testing — ideally named (ISO-accredited). Contaminant testing (heavy metals) is a plus but separate from potency.
- Do the math: colostrum grams × IgG % = grams of IgG, then divide the price per serving by that. It's the only apples-to-apples cost.
- Look past the sourcing story until the potency is disclosed. First-milking, grass-fed, and "cold-chain" are nice, but they don't tell you the dose.
Verification check · Colostrum
What we could and could not verify about Colostrum
That is what each seller's listing states. For the Canada edition we read the Amazon.ca listing title and details for every product on this page; we have not confirmed each of these SKUs against the certifier's registry the way the US edition does. 1 of the 3 carry a Health Canada natural product number (NPN) instead, which licenses the product for sale and is not a laboratory test of the bottle. No product on this page names an independent certifier on its listing.
Method: our Colostrum roster matched against the full public registries of third-party-certified supplements in the US, NSF/ANSI 173, USP Verified and Informed Sport, 5,317 listings, retrieved 2026-08-25. Absence means nobody independent has checked that Colostrum product, not that it failed. Full method and limitations.
Frequently asked questions
What is the best colostrum supplement?
The one that discloses its IgG. All three products in the Canadian catalog do: our best overall is Energievoll Bovine Colostrum (minimum 60% IgG, the cheapest per gram of actual IgG of the three). New Roots Herbal, a Canadian brand, states 650 mg of IgG directly; Herba's capsules disclose a minimum 30% IgG and carry a Health Canada NPN, but cost more per gram of IgG.
How do I choose a good colostrum?
Require a disclosed minimum IgG %, lab/batch testing, and a sensible cost per gram of IgG (price/serving ÷ grams of IgG). Anything that only says "colostrum" or "immunoglobulins" without a number is asking for blind trust.
