Affiliate Disclosure
Last updated: January 2025
Vitaei participates in affiliate marketing programmes, including the Amazon Associates Programme and the iHerb Affiliate Programme. This means that when you click on certain product links on Vitaei and make a purchase, we may earn a small commission at no additional cost to you.
How affiliate links work
When you click a vendor link on a molecule card, expert protocol page, or protocol basket, you are directed to the retailer's website. If you complete a purchase within the attribution window (typically 24 hours for Amazon, 30 days for iHerb), Vitaei receives a small commission.
Editorial independence
Affiliate relationships do not influence our editorial content. Molecule evidence tiers, rankings, and recommendations are determined solely by the quality and quantity of human clinical trial data. We do not accept payment for higher placement in the molecule index, and we do not promote products that lack adequate clinical evidence.
Vendors are selected based on third-party purity verification (Labdoor, NSF, USP, or equivalent), not on commission rates. We regularly update vendor recommendations when better-verified alternatives become available.
Amazon Associates
Vitaei is a participant in the Amazon Services LLC Associates Programme, an affiliate advertising programme designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, Amazon.co.uk, and Amazon.de.
