Nutrition & Everyday Support for Living with Wilson Disease
Founded by a Wilson Disease patient. From the community, for the community.
Help shape what we build.
As the first to build a nutrition product for people living with Wilson disease, we want to build it with you. There are two ways you can contribute right now.
What is the hardest part of managing Wilson disease?
Our founder lives with Wilson disease herself and knows how hard the day-to-day can be. Tell us the biggest challenge you face — your answer directly shapes what we build.
Which packaged foods should we test for copper first?
Food labels don’t list copper, so “can I eat this?” often has no answer. Wendy and her friends are changing that — tell us the one packaged food you most want tested, and we’ll send it to a lab.
What we’re working on.
Short notes from the team and moments of recognition along the way. Leave your email and we’ll send them straight to you.
