WonderCow scored 46/100: appealing whole-colostrum sourcing and the field’s highest IgG claim, capped by a missing serving weight that makes that claim uncomputable. These alternatives give you numbers you can verify. All scored on the same rubric.
The alternatives, ranked
How to choose
WonderCow’s sourcing (whole, unskimmed, family-farm) is genuinely appealing, so if you trust the brand and don’t need to compute the dose, it’s a reasonable buy. But if you want to know how many milligrams of IgG you’re getting — the point of colostrum — you need a stated serving weight, and WonderCow doesn’t give one. The alternatives above that state both weight and IgG let you do the math.
Frequently asked questions
What is a good alternative to WonderCow Colostrum?
If you want a computable IgG dose, Earth Energy Colostrum states 2,000 mg at 25% IgG (500 mg) with a named testing standard (ownership disclosed). Cowboy states its grams (3 g) but, like WonderCow, no IgG.
Is WonderCow’s 40% IgG better than a 25% claim?
Not necessarily — 40% of an unstated serving weight can be more or less IgG than 25% of a stated 2,000 mg. Without WonderCow’s serving weight, the higher percentage isn’t a higher verifiable dose.
Which colostrum lets me compute the IgG dose?
A product that states both a serving weight and an IgG percentage. In our comparison, Earth Energy does both; WonderCow states the percentage but not the weight, leaving the actual milligrams unknown.
