Organ supplement batch and expiry dates
Two small print lines on a bottle do more work than most of the front label. The lot number says which batch your capsules came from. The expiry date says how long the maker stands behind that batch. Both are worth ten seconds before a bottle goes in the cupboard.
Where to find them
Usually stamped on the bottom of the bottle, printed along the label seam, or inked near the neck. If you cannot find either, that is a fair question to put to the maker before you buy again. The general order for reading the whole label is in how to read an organ supplement label, and the dates belong on that checklist, near the end.
What the dates mean for a dried food
Dried organs are a low-moisture food, so they keep well compared with fresh meat, but well is not forever. Past the expiry date the maker is no longer standing behind freshness or the amounts on the panel, including the serving figures in organ supplement serving size. Treat the date as the end of the promise, not as a cliff edge where a capsule turns dangerous overnight.
Storage does half the work
Cool, dry, lid on, out of the steamy spot above the stove. A bathroom cabinet full of shower steam is a poor home for any dried food. Heat and damp shorten the life the date assumes, which is why two bottles with the same date can age very differently in two kitchens.
Buying with the date in mind
A bottle you will finish in a month or two should have comfortably more than that left on it when it arrives. If a sale bottle shows up nearly out of date, that is information about the deal, and the weight context in dried organ weight on a label will not rescue it.
FAQ
Where is the lot number on an organ supplement?
Usually on the bottle bottom, along the label seam, or near the neck. It identifies the batch your capsules came from.
Can I take capsules after the expiry date?
The maker stops standing behind freshness and label amounts after that date. Sensible practice is to buy amounts you will finish well inside it.
Where should I store a bottle?
Somewhere cool and dry with the lid on. Steam and heat, like a cabinet over the stove or in a steamy bathroom, shorten its life.
