The verdict, first
This one splits on a single question: do you want to know the dose? Earth Energy discloses 2,000 mg of grass-fed bovine colostrum per scoop and claims ISO/IEC 17025-accredited lab testing. ARMRA — the brand that built the modern colostrum category — does not state its serving weight anywhere on its product page, so no one can say how much colostrum a serving contains or what a gram of it costs.
ARMRA’s counterpunch is real: price. At roughly $1.00 per serving against Earth Energy’s $2.00 ($1.60 on subscription), it’s about half the cost per scoop. If the undisclosed serving weight doesn’t bother you, that math is hard to beat. It bothers us — knowing the amount is most of the reason this publication exists. You now have both sides; the table below has the rest.

The dose question — where this match is decided
Colostrum is sold by the scoop, but it works — to whatever extent research supports it — by the gram. Earth Energy’s label answers the gram question directly: 2,000 mg per scoop. ARMRA’s product page, as of July 12, 2026, does not state its serving weight at all. Its marketing describes proprietary processing and bioactive preservation, but a shopper cannot determine from the label how much colostrum a $1.00 serving contains — which also means the per-serving price advantage can’t be converted into a per-gram price at all.
That’s not a claim that ARMRA’s product is weak — it may be generous. It’s a claim that you can’t know, and on this site, “you can’t know” is the finding.
Testing: similar words, same missing document
Both brands make credible-sounding lab claims — ARMRA cites third-party testing in FDA-registered, ISO/IEC-certified labs; Earth Energy cites ISO/IEC 17025-accredited testing. Neither publishes batch certificates of analysis on its product page. Until either does, both claims sit in the same category: stated, plausible, unverified by published documents. We apply that standard to our sister brand exactly as we apply it to its competitor.
Which one fits you
Earth Energy makes more sense if…
- You want the dose on the label — 2,000 mg per scoop, stated plainly
- You value an ISO/IEC 17025 testing claim tied to a disclosed amount
- You’d rather pay $1.60–$2.00 per serving for a number you can hold the brand to
ARMRA makes more sense if…
- Lowest cost per serving is your deciding factor — it’s about half the price
- You want the biggest brand in the category, with the widest format range
- An undisclosed serving weight doesn’t bother you — though we’d argue it should
