Proposition 65

At Supplement Warehouse, your safety and transparency are our top priorities. California’s Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as Proposition 65, requires businesses to provide warnings when products sold in California may expose consumers to chemicals the State of California has identified as potentially causing cancer, birth defects, or other reproductive harm.

Why You May See a Proposition 65 Warning

Some supplements, foods, or ingredients may naturally contain trace levels of chemicals—such as heavy metals—that appear on California’s Proposition 65 list. These levels are often far below amounts considered harmful under federal or international safety standards.

Proposition 65 does not ban any products, nor does it indicate a product is unsafe; it is a right-to-know law requiring certain disclosures for California consumers.

Manufacturer Responsibility

Manufacturers are responsible for determining whether their products require a Proposition 65 warning and for providing that information to retailers. Supplement Warehouse does not independently test products for Proposition 65 chemicals and relies on manufacturers to supply proper labeling and warning language.

What This Means for You

A Proposition 65 warning simply means the product contains at least one chemical on the State of California’s list, not that the product violates any safety requirement. Products sold on SupplementWarehouse.com meet the standards required by federal law and can be safely used as directed.

If you have specific concerns or questions about a particular ingredient or product, we recommend contacting the manufacturer directly or consulting a qualified healthcare professional.
