Bisphenol A (aka BPA) is an industrial chemical used to make plastics & is often found in epoxy resins. BPA has been found to mimic estrogen inside the human body. This can cause many adverse and damaging effects on us, even in the small doses that leak through plastic bottles into our water.While there are health concerns linked to BPA exposure, there are three that we find most pressing: heart problems, lower testosterone & higher risk of cancer.Because of this, our cans are 100% BPA and estrogenic-free to maintain the integrity of our high-quality ingredients. It's important for us to Keep It Clean, and that means clean cans, too.
