Proposition 65 Disclaimer

What is Proposition 65?

Proposition 65 is a California law that requires businesses to provide warnings about exposure to toxic chemicals that may cause cancer, birth defects, or other reproductive harm. The law is designed to help Californians make informed decisions about the products they buy and the chemicals they are exposed to.

What types of chemicals are listed on Prop 65?

The Prop 65 list contains a wide range of natural and synthetic chemicals, including additives or ingredients in products like pesticides, common household items, and food products.

What does a Prop 65 warning mean?

A Prop 65 warning on a product means that it contains a chemical listed on the Prop 65 list. However, a warning does not necessarily mean that the product is unsafe or toxic. Many products contain Prop 65 chemicals at safe levels, known as "Safe Harbor Levels," and still display a warning.

It's important to note that the list is so large that a significant portion of the list does not have an established Safe Harbor Level. If any of these chemicals are present in a product, even if barely detectable, manufacturers are required to put a warning on the label.

Examples of chemicals on the Prop 65 list

The Prop 65 list includes both uncommon and common chemicals. For instance, alcoholic beverages, aloe vera, heavy metals, and aspirin are all on the list. Even products like fish oil and regular whey protein may display the Prop 65 warning because they are made of ingredients commonly vulnerable to Prop 65.

Another example is lead, which is naturally occurring in many parts of the world and environment. The Prop 65 limit for lead is 0.5 mcg/day, which is much lower than the amount found naturally in fruits, vegetables, and herbs. This limit is about 1000 times lower than the highest level of lead known to not cause reproductive harm.

What does "Known to the State of California to cause [cancer] [birth defects or other reproductive harm]" mean?

This phrase indicates that the chemicals used in a product have been listed by one of four listing mechanisms. These mechanisms include Labor Code, State's Qualified Experts, Authoritative Bodies, and Formally Required to be Labeled.

Proposition 65 warnings do not present information about the safety or risk of any products, nor do they ban products. The FDA is the final authority on food, drug, and beauty safety. The presence of a Prop 65-listed chemical in a product does not necessarily mean that the product is unsafe or poses a health risk. Rather, the warning is intended to inform consumers about the potential presence of a listed chemical.

Please note that Strong Supplements LLC does not object to compliance with Prop 65, despite our position that the required labels may be misleading rather than informative. We are committed to providing our customers with high-quality, safe products, and we work with our suppliers to ensure that all products sold on our website comply with Prop 65 requirements.
