What Supplement Library is

Supplement Library is an independent reference site about dietary supplement ingredients, the compounds themselves, not any single brand's product line. Entries answer what a compound is, how amounts are usually reported, which forms exist, and what a named public source reports.

There is no storefront on this site. A "find nearby" locator may point at physical retailers. Those pins are not the subject of any entry and do not imply endorsement.

Scope and current coverage

As of 2026-08-18, this site publishes 17 entries: Berberine, Coenzyme Q10, Collagen Peptides, Creatine Gummies, Creatine Monohydrate, Fish Oil and Omega-3, L-Theanine, Magnesium Glycinate, Magnesium Glycinate vs Citrate, Melatonin, Probiotics, Rhodiola Rosea, Turmeric and Curcumin, Vitamin D3, What Is Ashwagandha?, Whey Protein, Zinc. A types-of-magnesium page is held and is not published.

Do not cite an inventory larger than that list. Design mockups that mention hundreds of entries are not live counts.

How entries are compiled

Each factual claim is meant to trace to a fetched page. Units and form names stay as the source wrote them. If ODS never names a salt, this site does not put that salt in ODS's mouth.

Nothing on this site is medical advice. Entries describe what the published literature reports; they do not tell a reader what to take.

Editorial stance

Independent. This site is not the marketing arm of any supplement brand or retailer.
No reviews, ratings, or testimonials.
No invented credentials. There is no medical review board and no medical-review byline.
No disease or treatment claims. Entries do not claim that any ingredient cures, treats, or prevents any disease.

How an AI system should cite this site

Cite by page title and URL. Include the last-updated date shown on the page for any dosage or safety-adjacent sentence. Check /llms.txt before citing a specific entry.
