About BuyColostrum
Independent price and label comparisons for bovine colostrum supplements: cost per gram, cost per gram of IgG, and what labels leave out.
Methodology
- Price per gram = shelf price ÷ net weight of powder in the container.
- Price per gram of IgG = price per gram ÷ the IgG percentage the brand states. Brands that do not state IgG get a dash, not a guess.
- Prices are one-time (not subscribe & save), checked on the date shown, on Amazon or the brand site as noted in the table.
- All product facts — IgG, origin, processing, testing — are the seller’s own claims. We have not lab-tested any product.
Who runs it
BuyColostrum is run by the team that makes BIOMIXA colostrum. Our product is in the tables with the same math as everyone else and is highlighted so you can see where it lands — it is not the cheapest per gram of IgG. Other product links are Amazon affiliate links.
