Your legacy can change the future for animals and people.

Replacing Animal Research is an independent charity building a world where no animal suffers for science, while helping scientists develop research that is truly human-relevant.

Every year, it’s estimated that over 100 million animals are used in research worldwide. We fund innovative studies, including our innovation grants, train and support researchers at every stage of their career, and influence policy to advance the replacement of animals with effective, non-animal methods. Every project we support replaces animals in research while driving discoveries that improve human health: safer medicines, more reliable results, and research that makes a better world for animals and humans.

A gift in your Will can turn this vision into reality. It ensures the work you care about continues to grow, leaving a lasting legacy of compassion, progress, and hope. Your support helps scientists explore bold, human-relevant approaches, accelerates breakthroughs that make a real difference in people’s lives, and ensures animals are protected for generations to come. It also strengthens a movement for kinder, smarter science, supporting researchers, educators, and policymakers who are committed to creating lasting change.

By including Replacing Animal Research in your plans, you can be part of a better future for animals and humans, where science is smarter, more effective, and transformative.
