What to Know About Colostrum Supplements

8. What to Look for in a Supplement Label

Colostrum supplement labels can be confusing — and not all claims are regulated. Phrases like “first milking,” “high IgG,” or “grass-fed” sound promising, but they don’t guarantee product quality or potency.

Look instead for companies that share detailed sourcing information and test their products for purity and consistency. Third-party testing, good manufacturing practice (GMP) certification, or transparent lab results are good signs that a brand takes quality seriously.

Also check the serving size and protein content. Some colostrum powders contain meaningful amounts of bioactive compounds, while others are mostly fillers. If the label doesn’t clearly say what you’re getting — or how much — that’s worth questioning.
