Short answer: The National Center for Complementary and Integrative Health reports that berberine exposure has been linked to a harmful buildup of bilirubin in infants, which can cause brain damage — likely unsafe for infants and possibly unsafe during pregnancy or breastfeeding.
Why this exclusion is grounded in a specific, cited mechanism
Rather than a generic pregnancy caution, this exclusion names the specific concern — bilirubin buildup — and cites NCCIH directly as the source, a genuinely research-grounded rather than precautionary-only caution.
Why this applies to breastfeeding as well as pregnancy
Berberine can pass through breast milk, meaning the infant exposure risk extends beyond pregnancy alone into the breastfeeding period as well.
What to do if you're pregnant, breastfeeding, or considering it
Speak with your OB-GYN or a qualified healthcare provider about pregnancy-safe options — this specific formula is not the right starting point during this period.
