                                California's Proposition 65 requires warnings for products containing over 900 chemicals that can cause cancer or reproductive harm.  If you’ve ever wondered, "Why does my supplement have a P65 warning?" it's most likely due to trace amounts of naturally occurring heavy metals, like lead or cadmium, present in the ingredients. This mandatory label can be surprising and often misunderstood, leading to unnecessary consumer panic.
