ProBlend is made with real plant-based and mineral ingredients. Anything grown in soil picks up trace amounts of naturally occurring elements like lead, the same reason they show up in everyday foods like spinach, sweet potatoes, and rice. California's Proposition 65 sets some of the strictest disclosure limits in the world. Our testing found trace levels above that threshold, so the warning is on every bag. You should know exactly what's in your ProBlend, and we test so you can.
A Prop 65 warning doesn't mean a product breaks federal safety rules. ProBlend meets all FDA requirements for dietary supplements, is NSF Certified for Sport®, and every production batch is tested by independent third-party labs before it's sold. If you're pregnant or nursing, talk with your doctor before use.
