Be where the question is already being asked: 3,000 indexed pages in six languages
Vitamina D Explorer is a free, science-based solar vitamin D calculator. Its per-city and per-month pages draw around 20,000 Google impressions a month across six languages, answering people who want to know when they can synthesize vitamin D. When the answer is that today they can't, that's where your brand comes in.

Contextual relevance
Your product appears exactly when the answer is "not today" — when whoever asked cannot produce vitamin D naturally and a supplement is the logical next step.
Scientific credibility
Our calculations are based on Holick & Dowdy (2010) peer-reviewed research, and the method is published and auditable. The recommendations are grounded in science, not marketing.
Global & multilingual
Available in 6 languages (English, Spanish, French, German, Russian, Lithuanian), with pages for any city in the world. Vitamin D deficiency is a global problem.
Content that gets consulted, not an audience for rent
We are an early project and we are not selling you a user base: what we offer is surface. Thousands of indexed pages, six languages, and an MCP server that AI assistants can query directly. If you need immediate volume, we are not your fit; if you want to be in the answer when someone asks about vitamin D, we are.
