# How to use Supplements Comparison

Compare vitamins, minerals and nutritional supplements by exact product and pack, using dated UK retailer offers.

## Identify the exact item

Bring the product name, model or identifier you already have. Keep the variant and pack size with it, so similar-looking listings do not get treated as the same item.

## Compare the evidence alongside the offer

Use the linked searches and guides below. Compare the same variant, then check the dates, seller terms, delivery and any compatibility details shown by the source.

## Confirm the decision at its source

Open the relevant retailer or manufacturer page before buying. A saved offer or an identifier match does not by itself confirm stock, suitability or the final delivered price.
