Colostrum prices compared, per gram

$0.18–$0.98per gram of powder, across 9 popular brands

Serving sizes run from 1 g to 5 g, so “price per serving” tells you very little. We divide every price by the grams in the tub — and by the IgG the brand states, when it states one. Only 3 of 9 state a single IgG percentage; one more gives a range.

One-time prices checked October 9, 2026 on Amazon or brand sites. Product facts are the sellers’ claims. Methodology.

$2.67 per gram of IgG · $0.67 per gram of powder

Net weight is on the front label (1 oz = 28.35 g). IgG is usually in the Supplement Facts panel; if it is missing, the brand has not told you.

Nine colostrum powders, same math

Sorted by cost per gram of IgG, then by cost per gram. Lowest values in green. Our own brand is shaded.

Five label checks before you pay

  1. Find the net weight, not the serving count

    Servings are set by the brand. A 120-serving jar of 1 g scoops holds the same powder as a 40-serving jar of 3 g scoops. Divide price by grams.

  2. Look for an IgG number

    IgG is the most-cited active component. Of the nine popular powders in our table, only three state a single IgG percentage and one gives a 15–25% range. No number means you cannot compare potency.

  3. Read the ingredient list for one word

    Plain colostrum lists one ingredient. Flavored versions add sweeteners, flavors and fillers that dilute every gram you pay for.

  4. Check who tested it

    “Third-party tested” without a lab name or a certificate of analysis is a claim, not evidence. Ask the brand for a COA for your lot.

  5. Compare one-time prices

    Subscribe & save discounts change weekly. Compare list prices, then treat any discount as a bonus.

We make one of these.

BIOMIXA is our colostrum. It sits in the table with the same formula as the rest, and it is not the cheapest per gram of IgG. If price per gram is all you care about, buy the cheapest one in the table.
