Colostrum FAQ
Is bovine colostrum safe?
We only include brands that use pasteurized bovine colostrum and publish quality testing. Always consult your healthcare provider if you’re pregnant, nursing, or managing a condition.
How much IgG should I look for?
We recommend at least 15% IgG listed on the Supplement Facts panel, with per‑serving amounts disclosed.
Can I stack colostrum with protein?
Yes. Many users take colostrum alongside whey or collagen. If you prefer all‑in‑one, choose a formula that already includes ~2 g protein per 2 g serving.
