Supplement and vitamin brands operate in one of the most regulated consumer product categories. FDA dietary supplement regulations require specific documentation, storage conditions, and lot-level traceability that most 3PLs simply are not equipped to provide.**Why FIFO Matters for Supplements**FIFO stands for first in, first out. It means the oldest stock — the inventory that has been in the warehouse the longest — ships before newer stock. This prevents older products from sitting behind freshly received inventory until they approach or pass their expiration date.Most generic 3PLs do not enforce FIFO. They pick from wherever is convenient. For supplements, this means customers regularly receive products with short shelf lives — often leading to returns, negative reviews, and compliance risk.3PLCity enforces FIFO on all supplement inventory. Our WMS tracks inventory by lot and expiration date, and automatically directs pickers to the oldest lot first.**Lot Number Tracking for Recall Readiness**If a supplement product needs to be recalled — a contamination event, a labeling error, a quality hold — your 3PL needs to tell you immediately: which customers received products from the affected lot, with their shipping addresses and order dates.We generate lot-level recall reports in minutes. Every inbound supplement shipment is logged with lot number and expiration date. Every outbound order is recorded against the lot that shipped.**Climate-Controlled Storage**Heat and humidity degrade supplement potency. USP (United States Pharmacopeia) standard storage conditions for supplements are controlled room temperature — 68 to 77 degrees Fahrenheit.Our climate-managed zones maintain consistent temperature and humidity year-round.**90-Day Expiry Alerts**Products within 90 days of expiration are flagged in our system for priority fulfillment, markdown, or return to you. Expired products never ship to customers.
