Cowboy Colostrum Review: A Top Sourcing Story
3 g of first-day colostrum from grass-fed U.S. cows, calf-first and third-party tested.
Our verdict
Cowboy Colostrum
Cowboy Colostrum is a premium whole-colostrum option with strong sourcing transparency. The unflavored formula provides 3 g per serving, uses first-day colostrum from grass-fed U.S. dairy cows, preserves the whole-fat fraction, and is third-party tested. The current one-time price is $69 for 40 servings. Its main information gap is that an IgG percentage is not prominently disclosed.
Same parent company as this siteEarth Energy is owned by LJ Global Inc., which also owns Healthy Expert Reviews. Details
IMPORTANT: Cowboy does not need a fake weakness. Its 3 g serving is larger than Earth Energy's, and its whole, unstripped first-day positioning is compelling. The real decision is whether those sourcing details are worth the higher cost per serving without a published IgG percentage.
Cowboy has one of the best sourcing stories. But sourcing is not potency.
“First-day.”
“Whole.”
“Unstripped.”
“Grass-fed U.S. cows.”
Those are meaningful quality signals.
Cowboy also gives you 3 grams per serving, which is more than Earth Energy and ARMRA's standard serving.
Where the comparison gets harder is IgG.
Cowboy tells you a lot about where the colostrum comes from and how it is handled.
It does not prominently tell you the IgG percentage.
That does not make the product weak.
It means the buyer has a sourcing story and a gram dose, but less potency information than some competitors publish.

Cowboy wins on serving size. Earth Energy wins on potency disclosure.
Cowboy gives you more colostrum per serving.
That deserves to be said plainly.
Earth Energy gives you one metric Cowboy does not put front and center: 25% IgG.
It also names Grade A U.S. sourcing and the ISO/IEC 17025 testing standard.
So this is a real preference call.
Choose Cowboy if whole first-day sourcing and a 3 g serving matter most.
Choose Earth Energy if you want the IgG standard and lab framework published alongside the dose.

Final thoughts
Cowboy is one of the strongest competitors in this group. Its 3 g serving, first-day collection, whole-fat approach, calf-first policy and U.S. grass-fed sourcing are all meaningful differentiators. We would like to see an IgG percentage published as prominently as the sourcing details. Earth Energy gives up one gram per serving but adds a 25% IgG standard and more specific laboratory disclosure. Both are credible premium options; Earth Energy remains our more balanced pick.
