How are food supplements stored?
Food supplements are stored under the condition on their label, protected from heat and humidity, with batch and expiry records. Vague statements such as 'store in a cool, dry place' need a numerical range agreed in writing with the brand owner.

Food supplements come as tablets, capsules, powders, liquids and gummies, and most of these forms react to heat and humidity. Storing them well means keeping them in the condition on their label, tracking their batches and rotating stock by expiry. This article looks at what supplements need in the warehouse.
Supplement or medicine?
In Türkiye, food supplements fall under food law and are supervised by the Ministry of Agriculture and Forestry. A product with the same active ingredient that is authorised as a medicine follows the rules for medicines instead. The label shows which one a product is, and the warehouse’s record-keeping follows from that. This article is about food supplements.
Why heat and humidity matter
In heat, gummies soften and stick together, powders absorb moisture and clump, and the coating of some tablets can deteriorate. Some probiotic products, which contain live microorganisms, ask for refrigerated storage. The label always decides which condition a product needs.
Humidity needs watching too. In damp air cartons lose strength, labels peel and some packaging allows moisture through. We cover humidity and packaging in a separate article.
What does “store in a cool, dry place” mean?
This common statement on supplement labels has no numerical limit, unlike a medicine label that says “Do not store above 25 °C”. To check whether a storage area meets it, the warehouse needs a range. Agreeing that range with the brand owner and writing it into the contract or the product data sheet prevents disputes later.
Batch tracking and FEFO
Most supplements carry a best-before date. Stock still rotates by date: the batch with the nearest date leaves first. The batch number is recorded at receipt, in storage and at dispatch, and in a recall those records show which batch went where. Our article on FEFO and batch traceability describes the routine in detail.
What to keep apart
Supplements are food, and they can pick up odours and chemical contamination. Strong-smelling goods, cleaning chemicals and similar products are not stored in the same area. Damaged packs, returns and batches under investigation are separated from saleable stock and blocked in the system as well.
Regular cleaning and preventive pest control are basic requirements for food, too. We describe how this works in a warehouse in our article on cleaning and pest control.
