How we evaluated it
Why we chose it What put it on our list
- It states its IgG. The label shows colostrum (pasteurized cow pre-milk) 3,000 mg with immunoglobulin G 540 mg per teaspoon, which is 18%. Our colostrum guide asks for the IgG to be on the label.
- The page says it is never defatted and spray-dried at low temperatures, with colostrum as the only ingredient and no blend. The label shows 1 g of fat and 15 calories per serving.
- The directions are one teaspoon twice a day, 6 g, close to the low end of the 6.4 to 20 g a day used in the immune trials in our guide.
- The page says the colostrum is USA-sourced and non-GMO and that you can trace every batch. Surthrival is a small Maine-based company with a short, readable label.
Trade-offs What to weigh before you buy
- No testing is mentioned anywhere we looked: no lab, certificate or claim of heavy-metal or pathogen testing on the product, FAQ or About pages. The label does say pasteurized.
- The page gives no collection window (first milking or hours after calving), no farm or state, and no grass-fed claim.
- At 18% IgG it is below the 25 to 30% our guide cites as a good target.
- At the full label dose of 6 g a day, a 6.5 oz tub lasts about 30 days, roughly $2 a day. The 1 kg size is about $205, or about $1.23 a day at 6 g.
What to know Details worth knowing first
Bovine colostrum is the first milk after a cow calves. Our colostrum guide says the best evidence is for lower gut permeability in athletes, and it asks for a product that states its IgG. Surthrival’s powder does: 540 mg of IgG in each 3 g teaspoon, from whole, never-defatted colostrum, low-temperature spray-dried.
What it does not do is say anything about testing. We found no lab, certificate or claim of heavy-metal or pathogen testing on its pages, and no collection window or farm. We are asking Surthrival for a certificate of analysis for the lot and for the collection window. Until it answers, treat its purity and sourcing as the maker’s word. If it can supply them, this is a plain, fairly priced whole colostrum.
It contains milk, so avoid it with a dairy allergy, and ask a clinician first if you are pregnant.
Quality & testing How it measures up against our checklist
| What we checked | What we found |
|---|---|
| Named sourcing Maker’s claim | USA-sourced, says the page, which also says you can trace every batch. No state or farms and no grass-fed claim. |
| Tested by lot Not verified | Not stated. No testing claim, lab name or certificate on the product, FAQ or About pages. |
| IgG per serving Maker’s claim | Label: colostrum 3,000 mg and immunoglobulin G 540 mg per 1 teaspoon (3 g), about 61 servings per 6.5 oz. No assay is shown. |
| Collection window Not verified | Not stated: first milking or hours after calving, and no farm or state. |
| Processing Maker’s claim | Pasteurized (per the label) and low-temperature spray-dried, never defatted. The temperatures are not stated. |
| A plain label Maker’s claim | Colostrum only. Contains milk. |
| Recalls, warning letters and Prop 65 Verified | No FDA warning letter is for Surthrival (search of fda.gov’s warning letters, 2026-10-22), and no Prop 65 notice in the California Attorney General’s database names Surthrival. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
