Support our mission
Help keep Vital Matrix free
We want this website and its information to always remain free, to benefit the general public. If our guides have helped you, a contribution helps us research more supplements, keep the library current, and stay independent, with no paywalls and no sponsored ratings.
Ways to support
Make a donation
Direct support funds the research, writing, and upkeep that keep every page free and free of paywalls.
Use our product links
When a supplement link is an affiliate link, buying through it may earn us a small commission at no extra cost to you, and never changes our ratings.
Share the site
Telling a friend or linking to a guide that helped you is a free and genuinely valuable way to support the mission.
Every contribution goes toward researching, maintaining, and expanding the library. We’re committed to transparency about how the site is funded, see our disclosure for details.
