Prostadine Lot and Certificate Numbers Explained

Two references: a lot code, PRO-26 / PR-2341, and a certificate of analysis code, PRO-2341-26-PR.

A lot code identifies a batch, so that the maker can trace where it was made and which bottles it went into. A certificate of analysis, or CoA, is the laboratory report on that batch.

Neither number is visible on the bottle images we hold. The certificate itself was not shown. So at present we hold two labels for documents, and neither document.

• The laboratory name, address and accreditation.
• The product name and lot code, matching your bottle.
• The test date and method for each result.
• Identity checks for each ingredient.
• Iodine in micrograms per serving.
• Lead, arsenic, cadmium and mercury results against stated limits.
• Microbial counts.

A certificate with only a pass stamp and no numbers is not a CoA in a useful sense. The FDA expects makers to verify identity, purity, strength and composition, and a buyer is entitled to ask for what that verification found (FDA, Using Dietary Supplements).

Then you cannot tie your bottle to any certificate, and any reference given to you is unconnected. Ask the seller where the lot code is printed. If a seller cannot say, treat it as a gap in traceability and weigh it in your decision.

Our batch verify page gives a script for the request and a place to record the reply.

If a batch has a problem, a recall can only reach buyers if the lot can be traced to them. A bottle with no lot code is a bottle that cannot be recalled by batch. For a liquid made with seaweed, the iodine and metals can vary between batches, so a batch-specific certificate is the only real check (NIH ODS, Iodine).
