Affiliate disclosure

Vital Core Lab is reader-supported. Many of the product links on this site are affiliate links. If you click an affiliate link and then purchase the product on the merchant’s official site, the merchant pays us a commission. The price you pay is the same whether you click our link or go to the merchant directly.

Compliance with FTC Endorsement Guides

This disclosure is provided in accordance with the U.S. Federal Trade Commission’s 16 CFR Part 255 (“Guides Concerning the Use of Endorsements and Testimonials in Advertising”). Whenever a page on this site contains an affiliate link to a product we may earn a commission from, that page also carries a clear disclosure to that effect.

Networks & relationships

The products we review are sold through their own merchant sites and through affiliate networks. The most common network in our coverage of dietary supplements is ClickBank, which handles the transaction, the refund process, and the affiliate payout. Other networks may be used for products outside the supplement category.

We do not have an exclusive relationship with any single brand or network. We add or remove brands from our coverage based on whether they meet our editorial criteria, not based on commission rate.

What a commission does and does not buy

• A commission does notbuy a positive review. Our editorial reviewer’s assessment is independent of the commercial relationship.
• A commission does not change which products we choose to cover. We select products based on reader interest and our own editorial judgment.
• A commission does fund the time required to write long-form, label-level reviews. Without affiliate revenue, this site would not exist.

Affiliate links are clearly marked

Affiliate links on this site carry the rel=“sponsored”attribute as recommended by Google’s search guidelines and required for transparency under the FTC guides. This is a machine-readable signal that the link is a commercial referral.

Refunds & returns

All refunds and returns are handled by the merchant or their affiliate network (typically ClickBank), not by Vital Core Lab. The guarantee terms shown on each review reflect what the merchant publishes on their official site at the time we last verified the offer.
