Advertiser Disclosure

Last updated October 2026

Supplement Ledger is supported by affiliate commissions. This page explains what that means for you.

Affiliate links

Many of the product links on our pages are affiliate links. If you click one and buy, the seller may pay us a commission. You pay the same price whether or not you use our link.

How this can affect what you see

We may earn money from some products we feature and not from others. That can influence which products appear in a guide and the order in which they are shown. To limit the effect, we use the same written criteria for every product in a category, we show the points taken off each score, and we explain our reasons on the page.

What stays the same

• We score only what a product publishes on its label or official page.
• We say when an amount or an ingredient is not published.
• We do not claim that a supplement treats, cures or prevents a disease.
• We mark paid links with nofollow sponsored.

Not medical advice

Our guides are for information only. Results vary from person to person. Talk to a doctor or pharmacist before you start a supplement, especially if you take medication, are pregnant or nursing, or have a medical condition.
