What no other API covers

LactMed covers drugs. DSLD covers supplements. Neither covers histamine, MCAS, rosacea, or probiotic strains. Clarity is the only multi-condition ingredient safety API. Five condition lenses, 20+ dimensions per ingredient, 172 bacterial strain profiles, measured biogenic amine concentrations. Built on published methodology with DOIs (Beta-Glucan Galactagogue, CMPA Formula Analysis).

Histamine + MCAS

Measured histamine (mg/kg) for 35+ foods. Putrescine, tyramine, cadaverine. 172 bacterial strains profiled for histamine production. 268 MCAS triggers flagged.

Rosacea Triggers

Food and skincare ingredients checked for vasodilation, cinnamaldehyde, mast cell activation, and histamine. 92 skincare actives. 268 food triggers.

CMPA + Allergens

Full cross-reactivity chain: cow, goat, sheep, buffalo, A2 milk. Big 9 allergen classification. Hidden dairy flagged. Safe alternatives mapped.

Asthma + Allergy

89 asthma triggers flagged. Sulfites, histamine-mediated bronchoconstriction. RCT-backed: high-histamine diet reduces peak flow (p=0.0006).

Hidradenitis Suppurativa

Dairy, brewer's yeast (87% flare rate), glycemic index, nightshades. Mast cell pathway connection to histamine and DAO.

Probiotic Strains

172 histamine-forming bacteria catalogued. 17 commercial probiotics flagged. L. reuteri: 8,510 ng/mL measured. Strain-level safety data.

DAO + Biogenic Amines

DAO inhibitors, putrescine (mg/kg), tyramine. The hidden mechanism: foods that block histamine clearance even if they contain no histamine.

Contaminants + Recalls

174 products tested for arsenic, lead, cadmium, mercury, glyphosate. 103 FDA recalls. Barcode lookup returns contaminant alerts.

Formula Analysis

18 infant formula profiles, 15-dimension comparison. Nutramigen vs HiPP HA. Based on published CMPA Formula Analysis (DOI: 10.5281/zenodo.19391415).
