About Vitamin Guide

Vitamin Guide was created to provide a clear, comprehensive, and trustworthy reference for vitamins, minerals, and essential nutrients. Whether you're a health enthusiast, a student, or just curious about what's in your supplement bottle, we're here to help.

What We Offer

  • 140+ verified vitamins and nutrients — from A to Z, including all essential vitamins, minerals, and bioactive compounds.
  • Detailed functions — what each nutrient does in the body, backed by nutritional science.
  • Food sources — natural ways to get your nutrients from whole foods.

Our Philosophy

We believe that good nutrition is the foundation of health. Our goal is to make vitamin and nutrient information accessible, understandable, and actionable for everyone — without the hype or the jargon.

How We're Different

  • No products for sale — we're a reference, not a store.
  • No ads disguised as content — our information is independent.
  • AI-assisted, human-curated — we use technology to scale, but we verify and refine.

Want to go deeper? Our Guides section covers how vitamins actually work, how to read a supplement label, and how to spot pseudo-vitamin misinformation like the substances sometimes marketed as "vitamin B15" or "vitamin B17" — which aren't recognized vitamins and aren't included anywhere in our database.
