RavintolisäWiki is a Finnish-language information resource focused on ingredients used in dietary supplements. Its purpose is to provide readers with evidence-based information about the effects of these ingredients, drawing on research evidence and, for plants, information about traditional use where relevant. The site organizes its content as a browsable and searchable ingredient reference, with 268 ingredients listed on its home page.

Topics include vitamins such as B6, herbs and botanicals such as sage, sea buckthorn oil and St. John’s wort, and mushroom ingredients such as lion’s mane. Visitors can search for a specific ingredient or explore the directory and recently updated pages, which also feature subjects including lemon balm, black tea, ivy, mistletoe, myrrh and mint.

RavintolisäWiki is therefore designed as an educational resource for people seeking information about supplement ingredients, rather than as a product catalogue. The site also provides standard wiki features, including page details, printable versions and links to related pages, alongside information about its privacy policy, disclaimers and editorial resource
