Stack Tender

Stack Tender is a supplement tracking tool. Its public stack pages let visitors view a supplement catalog of over 300 items without creating an account. According to the site, the content is AI-generated through a process that pulls recent research, finds sources for dosage information, and identifies contraindications, interactions, and synergies between supplements.

The creator built the tool initially for personal use and added features over time. The page title also references product scanning. It is aimed at people who take health supplements.
