Identity
Verifies that each ingredient is what the label says — by HPLC, mass spectrometry, or microscopy depending on the active. Catches substitution, adulteration, and mislabeling.
§ Transparency — COAs
Every lot. Every test. On the label.
Every Vitamologist bottle is independently tested before it reaches you. The Certificate of Analysis for that specific manufacturing lot is one QR scan away — from your phone, from the front label.
Scan to verify
Open the camera on your phone. Aim at the QR code on the front of any Vitamologist bottle. The page that opens is the Certificate of Analysis for the exact lot in your hand. Identity, potency, heavy metal screen, microbiology — all signed by an ISO/IEC 17025 accredited third-party laboratory.
What we test for
Potency
Confirms each active is present at the dose declared on the panel. Probiotic CFU counts are tested at expiry, not manufacture — so the count on the label is the count you take.
Heavy Metals
Lead, arsenic, cadmium, mercury — tested against US Pharmacopeia and California Prop 65 thresholds. Especially critical for plant extracts (Bacopa, Ashwagandha, Tart Cherry, Saffron).
Microbiology
Total aerobic count, yeast and mold, E. coli, Salmonella, Staphylococcus aureus — tested per USP <2021> / <2022> standards.
Lot archive
A browsable archive of all published COAs (organized by SKU and lot number) goes live with our first Amazon shipment. Until then, scan the QR on any sample bottle for that lot's report.
Lot archive launches with first production batch · Summer 2026
