WonderCow’s pitch is whole, unskimmed, family-farm colostrum. Here’s the file.

WonderCow products we’ve scored

The record, in brief

Strengths: whole unskimmed colostrum, seventh-generation family-farm sourcing, and the highest IgG claim in the comparison (40%). Cons: no stated serving weight (so the IgG dose is uncomputable), and a GMP claim with no named independent testing standard.

How we score WonderCow

Every WonderCow product is scored on the same public 100-point methodology as every other brand — formula, dosage & label transparency, testing, value, experience and brand record — with every fact dated and sourced.

Frequently asked questions

Is WonderCow worth it?

If you trust the sourcing and don’t need the math, it’s reasonable; if you want to know the actual IgG, its missing serving weight makes the 40% claim uncomputable. Its worth-it page does the math.

Is WonderCow’s 40% IgG meaningful?

Only partly — 40% of an unstated serving weight can’t be converted into milligrams of IgG. A stated percentage of a stated weight tells you more.
