Hi there! Many foods naturally have some variability in chemical content, which can be contributed to changes in growing conditions, like soil matter, irrigation water, and fertilizer composition just to name a few. At Vital, we closely and consistently monitor our products' nutritional and chemical make up. And if that data ever triggers a warning notice, our consumers can confidently trust that we'll provide them with the information they need to make an educated decision about the products they use. A Prop 65 warning notice on a VP product does not mean the product is unsafe. Rather, the notice is intended to inform California consumers of a listed chemical so the consumer can make an informed decision when purchasing that product.
