Editorial policy: how we prepare our content

This page explains how the site's guides, category texts and product descriptions are made. Food supplements are a health topic, so it matters who wrote a text, what it is based on and where its limits are.

Who writes and checks the content

We write the texts with the help of AI tools and edit them ourselves. Each language is written separately, not translated from another. Before publication, guides and product descriptions are reviewed by Inese Kalniņa, dietitian. She checks that the text matches its sources, that health claims come from the EU list of permitted claims and that it makes no promises a supplement cannot keep. She reviews the texts but does not recommend specific products. We do not present ourselves as medical advisers.

What we rely on

  • Permitted health claims: Commission Regulation (EU) No 432/2012 and the EU Register of nutrition and health claims.
  • Reference intakes and upper limits: EFSA scientific opinions.
  • Information on substances, forms and safety: fact sheets from the US National Institutes of Health Office of Dietary Supplements (NIH ODS).
  • Product data: the pack label and manufacturer information. Before a product is published, the figures in the text are checked against the label.

Every guide ends with a list of the sources used.

How health claims are chosen

A health effect is stated only when it is on the EU list of permitted claims, in the official wording for that language, and the product contains the amount the claim requires. Where the EU allows no claim for a substance, we say so and compare form, dose and label data instead. We never write that a supplement treats, prevents or cures a disease.

What our texts are not

The texts are general information and do not replace advice from a doctor or pharmacist. Pregnant or breastfeeding women, people taking medication or living with a condition, and anyone buying supplements for a child should consult a specialist before starting. Whether a nutrient is lacking is shown by a blood test and a doctor, not by a web page.

Selling and writing

We sell the products mentioned in the guides. Forms and doses in the guides are compared on label figures, and we take no money from manufacturers for changing a text.

Dates and updates

Each guide shows the date of its last review. Guides are reviewed at least once a year, and sooner when a regulation or an EFSA opinion changes. Last review of this policy: 2026-11-08.
