Did California make it illegal to sell minors creatine supplements?

Lea este artículo en español aquí.

Starting on Jan. 1, 2027, merchants will be barred from selling creatine to minors.

California’s Assembly Bill 2030, signed into law by Gov. Newsom in September 2026, prevents the sale of all muscle building and weight loss supplements to those under 18.

Merchants must ID potential buyers who appear to be minors. Exceptions are made for those with a prescription. 

For online sales and delivery, merchants must confirm the buyer’s name, birthdate and address through an age-verification database, or require an adult to sign for the package and show photo ID.

Sellers can be fined up to $500 per violation and courts can order them to stop.

Creatine is a protein produced in the body by amino acids or directly from red meat and fish and stored in muscle tissue. It is used as a supplement for weight and muscle gain.
