What Clarity checks for

More than safe or unsafe.
Four dimensions, one answer.

Most supplement safety tools stop at lactation. Clarity goes further — checking every ingredient across four simultaneous dimensions that matter postpartum: lactation safety, histamine signal, DAO enzyme interaction, and cycle-phase sensitivity.

Some breastfeeding mothers notice their baby is fussier, harder to settle, or more wakeful after certain meals. While individual responses vary, histamine-containing foods and supplements may be worth exploring as a possible factor — particularly for babies who seem sensitive after feeds. Clarity flags ingredients that may be worth discussing with your provider if you're noticing patterns.

This is not diagnosis. It is a starting point — giving you the information to have a more informed conversation with your clinician.

"I had no idea spinach was high in histamine. I was eating it every day and my baby wasn't sleeping. Clarity was the first thing that suggested it might be connected."

🍼 Lactation Safety
Evidence-graded verdict sourced from LactMed (NIH), DSLD, InfantRisk, and MilkSafe. Gold, Silver, and Bronze evidence tiers with PMID citations where available.
🧬 Histamine Signal
Whether the ingredient is a histamine liberator or contains histamine — relevant postpartum when hormonal changes may affect histamine tolerance.
⚗️ DAO Enzyme
Whether the ingredient inhibits diamine oxidase — the enzyme that clears histamine. Combined with histamine content, this creates a distinct risk profile per ingredient.
🌙 Cycle-Phase Sensitivity
Caution flags by menstrual cycle phase as it returns postpartum. Ovulation and luteal phases may amplify certain ingredient effects.
