Supplement Facts RankClear Choices, Better Absorption

About SupplementFactsRank

Supplement Facts, Reimagined: a catalog of multivitamins with a unique, standardized system for evaluating the bioavailability of each ingredient. We help you choose products not just by ingredient list, but by the potential absorbability of every form — instantly see which nutrients are truly available, making your choice more informed.

Mission & Value

Anyone shopping for vitamins faces hundreds of options and confusing ingredient lists. The mission of SupplementFactsRank is to provide a tool for conscious selection and honest comparison of multivitamins based on the bioavailability of their ingredients. We structure open data, cut through marketing noise, and present it visually — so your decision is truly informed.

How it Works

We analyze Supplement Facts, evaluate ingredient forms, and present it visually — so you can choose with confidence.

  1. We scan the product's Supplement Facts and break down each ingredient by its specific form.
  2. For every form, we assign a bioavailability rating using a unified scale — from Very Low to Superior High.
  3. Each ingredient receives its own bioavailability level, clearly visualized with color indicators.
  4. The product receives an integrated Product Bioavailability Index (PBI) — showing how absorbable the overall formula may be.
  5. Everything is shown in a clear table: you instantly see the strong and weak points of each formula.
  6. You can compare products by bioavailability index, review the full breakdown, and make decisions free from marketing illusions.
  7. All data is in one place — no need to hunt for information across different sites.

Why Standard Comparisons Don't Work

  1. Supplement Facts on product labels are just lists — they say nothing about how well the ingredients are actually absorbed.
  2. Most comparison sites focus only on ingredients and price, not the quality or bioavailability of each form.
  3. We rate not only the formula, but the 'quality' of every ingredient form — so you see not just 'how much,' but 'how well it may be absorbed.'
  4. SupplementFactsRank is your usual Supplement Facts — but with a new column: Bioavailability Level. Everything is clear, with no hidden details.

Who Should Use

Anyone who wants to choose a multivitamin quickly and confidently, focusing on absorbability — not just price or label claims.

  • People without a science background who still want to know what they're taking.
  • Those who value simplicity and clarity — and don't want to waste time deciphering labels and ingredient lists.
  • Shoppers who want to compare products by the quality of ingredient forms, not just by quantity or cost.
  • Parents looking out for what their kids and family are really consuming.
  • Anyone tired of overpaying for underperforming formulas.

Limitations & Transparency

  • All information is based on open sources and manufacturer-supplied data.
  • We do not conduct laboratory testing or physically verify products.
  • Bioavailability ratings are expert-driven, based on analysis of scientific literature, published reviews, and automated AI processing followed by manual validation.
  • Ratings serve as a guide, not absolute truth.
  • If an ingredient's form is not specified or details are hidden, we use a market-average rating ('default') or mark it as 'Variable.'
  • Our methodology and database are updated regularly, but we can't cover every product or new formula instantly.
  • All information is for reference only and is not a medical recommendation.
  • Errors or outdated information are possible — if you spot an inaccuracy, please let us know.

We strive for maximum transparency and accuracy, but recommend using SupplementFactsRank as an additional tool for informed choice — not as your sole source of information.

Roadmap & What's Next

  • In the near term, we plan to analyze all major multivitamins to make the database as complete and up-to-date as possible.
  • Next steps: adding other product types (minerals, omega-3s, specialty formulas).
  • We are working toward automated updates using AI agents and expanding manual review.
  • In the future: an interactive assistant for personalized queries (goal-based product suggestions, ingredient analysis, label parsing).
  • We'll rapidly respond to feedback and user suggestions to keep improving the platform.
  • Feature release timelines depend on project demand and available resources. All updates are announced on the site.
