Short answer: Not for pregnancy, breastfeeding or infants. NCCIH reports berberine has been linked to a harmful buildup of bilirubin in infants, which can cause brain damage.
Why this exclusion is stated with unusual specificity
Rather than a generic "consult your doctor if pregnant" caution, naming the specific bilirubin-buildup risk in infants reflects a genuinely more precise, serious safety disclosure.
Why this applies to breastfeeding, not just pregnancy
Should not be used in pregnancy or breastfeeding or given to infants — all three circumstances named directly, not just the pregnancy scenario alone.
⚠️ Worth knowing: berberine is specifically flagged as unsafe here — among the clearest, most direct exclusions on the entire site.
