The verdict, first
This one splits on a single question: do you want to know the dose? Earth Energy's printed Supplement Facts label states 2,000 mg of whole bovine colostrum per 2 g scoop at 25% IgG — 500 mg of IgG per serving — with ISO/IEC 17025-accredited lab testing claimed. 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.
The price gap we originally reported is gone. Verified against the printed label (July 14, 2026), Earth Energy's jar holds 60 servings, not the 30 our first product-page read suggested — so both products cost about $1.00 per serving, and Earth Energy drops to $0.80 on subscription. That leaves one real difference: ARMRA is the bigger brand with the wider format range, and its serving weight is still nowhere on the page. 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 — or what a gram of it costs. Earth Energy’s label goes a step further than dose: it also states 25% IgG, making it the only product of the two whose IgG delivery (500 mg per serving) can be read off the label.
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 both brands identically.
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 want the numbers on the label — dose and IgG — at $0.80–$1.00 per serving
ARMRA makes more sense if…
- You want the biggest brand in the category at the same ≈$1.00 per serving
- 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
