Pros and cons
Colostrum Unflavored
- One ingredient: 1 g of grass-fed US bovine colostrum per scoop, with no additives, sweeteners or flow agents
- Brand reports third-party testing of every production run for heavy metals, glyphosate and microbes, with cGMP manufacturing
- Neutral, malty taste that works dry-scooped or stirred into cool drinks and food
- Bovine colostrum has some placebo-controlled evidence for gut-permeability markers and upper respiratory symptoms in athletes
- About $4 a day at ARMRA's suggested four-plus scoops, roughly $120 a month
- Immunoglobulin (IgG) content is not disclosed, so potency cannot be compared with other colostrum
- Respiratory-symptom trials used 10 to 20 g a day, gut trials were tiny, and ARMRA's own human data is an uncontrolled survey
- Clumps in liquid, and some buyers report cracked jars and spilled powder
60 Billion Probiotic
- The brand guarantees 60 billion CFU through expiration, not just at manufacture
- Third-party tested (the brand names Eurofins and Light Labs) and Non-GMO Project Verified
- About 60–83 cents a day, depending on bottle size
- Once-daily, shelf-stable, acid-resistant capsule
- No strain designations, so the formula can't be matched to clinical trials
- Proprietary blend: one total for 10 species, with no per-strain amounts
- The inulin prebiotic may cause gas in FODMAP-sensitive people
- Made in a facility that also processes major allergens
Our verdicts
Colostrum Unflavored
ARMRA is a clean, single-ingredient colostrum from a brand that says it tests every batch for contaminants, and many loyal users credit it with less bloating. But the price is steep, the IgG content is undisclosed, and the gut and immune evidence comes from small, short trials, mostly in athletes and often at much larger doses. Think of it as an expensive experiment rather than a proven gut-health staple; fiber or a well-studied probiotic is a cheaper, better-supported first step.

60 Billion Probiotic
This is a well-made, well-priced, third-party-tested daily probiotic, which explains its popularity. But without strain designations or per-strain doses, you're buying a high CFU count rather than a formula matched to clinical research. It's a reasonable budget multi-strain option, not an evidence-based pick for a specific goal.
