How we score
Six weighted categories. One public methodology. Applied identically to every product — including brands we have a relationship with.
A consistent summary of formula, transparency, value and experience. Not a medical rating.
Head to head
The verdict comes first, then the full table: doses, sweeteners, testing and cost per serving.
Only three of the five disclose their colostrum dose — and only one states its IgG. Prices from $29.99 to $119.99. The table settles it.
See the comparison$3.00 vs $1.80 a day, one NSF certification, zero disclosed amounts on either label. The table settles it.
See the matchupEvery amount on one label, none on the other — at half the price. The table settles it line by line.
See the matchupThe category heavyweight vs the disclosed-dose challenger — both labels, every number, dated.

“The label names all 31 ingredients — then discloses no individual amounts. You cannot determine how much of anything a serving provides.”
“The $119.99 jar doesn’t state its serving weight. The $59.95 jar discloses 2,000 mg per scoop. Price and transparency are not the same thing.”
“A 2019 FDA warning letter, 2023 federal consent decrees, and a $9.95 million class settlement — the record most reviews skip.”
