California bars sales of weight loss supplements and diet pills to minors, with age verification for online orders
AB 2030, signed September 28, 2026, prohibits selling over the counter diet pills and weight loss or muscle building supplements to anyone under 18 in California. Delivery sellers, including online retailers, must verify age through an independent database or require an adult signature with photo identification, with civil penalties of up to $500 per violation.
Assembly Bill 2030 adds section 109030 to the Health and Safety Code. No person may sell, offer or give away an over the counter diet pill or a dietary supplement for weight loss or muscle building to a person in California under 18. A retail establishment, a term that expressly includes pharmacies and vendors taking orders by mail, telephone, email, website or app, must request identification when it cannot reasonably tell that a buyer is an adult.
A delivery seller may not accept an order without either verifying the buyer's name, birth date and address against an independent, government sourced database, or shipping with an adult signature and photo identification on delivery. Violations carry a civil penalty of up to $500 each, enforceable by the Attorney General, county counsel or city attorney. The statute lists factors for deciding whether a product is marketed for weight loss or muscle building, including named ingredients and how a seller tags or groups the product. Minors with a prescription are exempt.
- Pharmacies with California storefronts that stock diet pills or weight loss and muscle building supplements.
- Online pharmacies and supplement retailers anywhere that ship those products to California addresses.
Applies to any retail establishment, including pharmacies, and to any delivery seller shipping these products to a California address, wherever the seller is located.

The weight loss category now has an age gate at the point of sale in the largest state, and for online sellers the gate is a verification step that must happen before an order is accepted. The statute's definition turns on how a product is labelled, marketed, tagged and grouped on a site, which is exactly the kind of public page content a certification review reads. A pharmacy whose site groups supplements under weight loss should expect to need the verification flow by the new year.
- Inventory which products on your site or shelves are labelled, tagged or grouped for weight loss or muscle building, using the statute's factor list.
- If you ship any of them to California, choose the compliance path now: independent database age verification at checkout, or adult signature delivery with photo identification.
- Diary January 1, 2027, and watch for any Attorney General guidance before then.
Website and Digital Presence. The Website and Digital Presence domain covers what a pharmacy's public pages offer and how products are presented. The statute's marketing factors and the checkout age gate both sit inside that review.
