Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Colostrum-IgG by Premier Research Labs
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: bovine colostrum, a nutrient-rich fluid produced by cows in the first days after giving birth. It's used as a dietary supplement for its immune and digestive properties.
Does it work?
Moderate evidence
The evidence for bovine colostrum is mixed. It's rated possibly effective for HIV/AIDS-related diarrhea, rotaviral diarrhea, and exercise-induced respiratory infections.
For necrotizing enterocolitis (NEC), a serious intestinal condition in newborns, it's rated possibly ineffective. The data we hold doesn't establish its effectiveness for other uses.
How safe is it?
Well-documented data
Bovine colostrum is generally well tolerated in most adults. However, if you have a milk or dairy allergy, you should avoid it.
A small number of trial participants reported mild bloating, nausea, diarrhea, and unsettled stomach at rates similar to those taking a whey-based control. In individuals with HIV-related diarrhea, there have been reports of nausea and vomiting, elevated liver function tests, and decreased blood cell counts — so extra caution is warranted if you're in that situation.
Safety data during pregnancy isn't reliable enough to recommend it, and there isn't enough information to know whether it's safe during breastfeeding — talk with your doctor or pharmacist before using it in either case.
Meds to double-check
No known interactions
No interactions are documented in our data for bovine colostrum. Still, check your exact medications with the tool on this page before you start, and let your doctor or pharmacist know you're considering it.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Bovine colostrum may help with certain types of infectious diarrhea and exercise-related infections, though the evidence is still developing. It's generally well tolerated, but steer clear if you have a dairy allergy, and check with your doctor or pharmacist before you take it — especially if you're pregnant, breastfeeding, or managing HIV-related illness.
