These particles can contain harmful chemicals that affect hormones, immunity, and overall health. Trace empowers you to make informed choices about your health by highlighting hidden sources of microplastics in your daily routine and suggesting safer alternatives. Whether it's switching from plastic food containers, choosing better laundry detergents, or improving your water filtration, Trace provides practical steps anyone can take to reduce their microplastic intake.
