How we compare on wovitamine.de

For wovitamine.de we analyse offers from major marketplaces and shops, sort them by nutrient and dosage form, and filter unrelated products out of the comparisons. Prices are updated regularly, and the price history shows whether an offer really is good value. Our texts are based on the reference values of the German Nutrition Society (DGE), the maximum-level recommendations of the German Federal Institute for Risk Assessment (BfR), EFSA assessments and the authorised EU health claims. We do not test products ourselves, make no health promises and are no substitute for medical advice.

wovitamine.de brings together offers from large marketplaces. We obtain the product data – title, image, price, retailer and, where available, ratings – automatically via the providers' official partner interfaces. We do not type in prices by hand and do not use data from unofficial sources.

The offers on wovitamine.de currently come from Amazon, eBay and AliExpress (German shops).

The data is synchronised automatically: the top offers on the home page roughly every two hours, the entire product catalogue at least twice a day. Products that are no longer available are removed from the comparison; their pages remain accessible for reference but are clearly marked as no longer listed.

Since July 2026 we have been storing the synchronised prices continuously. Where there are enough data points, the product page shows the price history and a price assessment – for example, whether an offer is currently below the average of the last 30 days.

What counts is always the retailer's price at the time of your purchase. It may change between two synchronisations; shipping costs may apply depending on the retailer.

The default sort order “Popular” first shows products with a current price, ordered by the customer rating at the retailer and then by the sales rank supplied by the marketplace. Alternatively, you can sort by price (ascending or descending) or by discount.

On our comparison and brand pages we hide used goods and only show vitamins that match the topic – selection rules such as price range or features are defined per topic.

Products linked with “To the offer” are commission links (affiliate links). If you buy through them, we receive a commission from the retailer. The price does not change for you. That is why all offers on wovitamine.de are labelled as “Ad”.

The amount of commission has no influence on selection or order: only product data such as price, rating, sales rank and discount feed into the sorting. There are no paid placements.

We do not test products in a lab ourselves and do not award test scores. Our guides and comparison pages explain buying criteria, technology and legal matters and show you which models are available at what price – the decision is yours.

Customer ratings come from the marketplaces; we do not invent or alter ratings.
