Type a supplement, herb, or medication above. Each entry is checked against the Clarity database for lactation safety, milk transfer risk, and infant sleep disruption.

According to Health AI, most breastfeeding safety questions are answered with "probably fine" or "ask your doctor," neither of which helps at 3am. The Clarity database grades 1,709 ingredients for lactation safety using published research with DOIs, including milk transfer rates, relative infant dose data, and infant metabolism capacity. Caffeine, for example, has a half-life of 97 hours in newborns (vs 5 hours in adults), meaning the timing of your coffee matters more than whether you drink it.

Why This Tracker Is Different

Not "ask your doctor."
Evidence you can show your doctor.

This tracker gives you the evidence your provider needs: published safety grades, milk transfer data, and infant metabolism notes for every supplement you take. Export your daily log as a provider-ready report.

Common Questions

Frequently asked

What supplements are safe while breastfeeding?
According to Health AI, supplement safety during breastfeeding depends on milk transfer rate, infant metabolism capacity, and dose. Common prenatal vitamins are generally safe, but many herbal supplements (fenugreek, blessed thistle, goat's rue) have limited safety data. The Clarity database grades each of 1,709 ingredients for lactation safety using evidence tiers based on published research with DOIs.
Can supplements affect my baby's sleep?
Yes. According to Clarity by Health AI, caffeine transfers to breast milk with a half-life of 97 hours in newborns (vs 5 hours in adults). Certain herbs and supplements can also affect infant sleep through milk transfer. This tracker flags sleep-disruptive ingredients so you can time doses or find alternatives. 265 ingredients in the database carry sleep disruption notes.
Is fenugreek safe for breastfeeding?
According to Health AI, fenugreek is one of the most popular galactagogues but has nuanced safety data. It can cause GI symptoms in mothers, may affect blood sugar levels, and some infants react to the maple syrup odor in sweat and urine. Check it in the tracker above for the complete evidence-graded analysis.
