Cowboy Colostrum scored 55/100: a big, honestly disclosed 3 g scoop with credible sourcing, capped by a missing IgG figure. If you want to know the active fraction you’re paying for, these alternatives state it. All are scored on the same rubric.
The alternatives, ranked
How to choose
If you value grams of whole colostrum above all and trust the sourcing, Cowboy’s 3 g scoop is genuinely competitive and you may keep it. If you want to know the IgG — the active immunoglobulin fraction — you need a label that states it, and Cowboy doesn’t. The alternatives above that state IgG let you price the thing colostrum is actually for.
Frequently asked questions
What is a good alternative to Cowboy Colostrum?
If you want a stated IgG figure you can price, Earth Energy Colostrum states 2,000 mg at 25% IgG (500 mg) with a named testing standard (ownership disclosed). ARMRA has strong sourcing but, like Cowboy, states no IgG.
Which colostrum states its IgG?
In our comparison, Earth Energy is the one product stating both a serving weight and an IgG percentage, letting you compute the milligrams of IgG. Cowboy, ARMRA and WonderCow each leave part of that math undone.
Is Cowboy’s big scoop still worth it?
If grams of whole colostrum are your priority and you trust the grass-fed sourcing, its 3 g scoop is competitively priced per gram. The catch is you can’t see the IgG fraction — the number colostrum’s benefits actually depend on.
