California AB 2030 Supplement Age Limit: What the Evidence Says

Short answer: California AB 2030 bars selling or giving away weight-loss and muscle-building supplements, and over-the-counter diet pills, to anyone under 18 without a prescription. It names no banned ingredient and requires age checks at stores and for online orders. Supporters point to concern about eating disorders in young people; the Natural Products Association says there is not a single data point connecting eating disorders to dietary supplements, and the industry group CRN is challenging a similar New York law in court.

What does California AB 2030 do?

The governor approved AB 2030 on September 28, 2026, and it was filed the same day as Chapter 720, Statutes of 2026. You can read the chaptered text on LegiScan copy of the chaptered text. The law adds Health and Safety Code section 109030 and does four main things:

• Bans sales to under-18s. No one may sell, offer to sell, or give away as a retail or wholesale promotion an over-the-counter diet pill or a dietary supplement for weight loss or muscle building to anyone under 18 in California.
• Requires ID in stores. A retail store must request valid identification from a buyer if it cannot reasonably determine that the person appears to be under 18. A store may also limit access to these products in a way designed to prevent unauthorized access.
• Sets rules for online and delivery sellers. A delivery seller, including an online retailer, may not ship these products to anyone under 18 in California. Before accepting an order, it must do either or both of the following: check the buyer’s full name, birth date and address against a commercially available database built mainly from government data and not controlled by the seller, or use a delivery method that requires an adult 18 or older to sign, showing a government-issued photo ID.
• Sets penalties. A violation carries a civil penalty of no more than $500 for each violation. The Attorney General, a county counsel or a city attorney can bring the case and can ask a court for an injunction. A prevailing plaintiff gets reasonable attorney’s fees and costs.

What does AB 2030 not cover?

• Any ingredient. The bill bans no ingredient outright.
• Adults. The section does not apply to a person 18 years of age or older.
• Under-18s with a prescription. The section does not apply to a person under 18 with a prescription for an over-the-counter diet pill or dietary supplement for weight loss or muscle building.
• Every supplement. A product is covered only if it is labeled, marketed or otherwise represented for weight loss or muscle building.

Which ingredients does the law mention?

The bill lists five ingredients in its factor section: creatine, green tea extract, raspberry ketone, garcinia cambogia and green coffee bean extract. A court may consider these, along with other factors, when deciding whether a supplement is labeled or marketed for weight loss or muscle building. The list is not limited to these five, and having one of them is a factor a court may weigh, not an automatic trigger. The other factors include:

• An ingredient the FDA has approved for weight loss or muscle building, or a steroid.
• Label or marketing statements that the product will help modify, maintain or reduce body weight, fat, appetite, overall metabolism or nutrient metabolism, or maintain or increase muscle or strength.
• How a store or online seller signs, tags, groups or displays the product.

KMK Law summary of the New York law describes creatine as a popular muscle-building ingredient and the other four as popular weight-loss ingredients. New York’s 2023 law uses the same five-ingredient list.

Quick facts as of 2026-11-09:

How does New York’s 2023 law compare?

CRN says CRN statement on California’s measure closely tracks New York’s 2023 law. The two laws differ in a few practical ways:

The New York details come from the KMK Law summary of the New York law and CRN’s CRN November 2023 alert. CRN said on May 5, 2026 that the U.S. Supreme Court was considering its petition; a 2024 federal ruling let its First Amendment claim proceed, as described in a Nutrition Insight report on the ruling.

What do supporters and opponents say?

Supporters start from concern about eating disorders in young people. CRN agrees with the goal. Its CEO, Steve Mister, said, “Protecting young people from eating disorders is an important objective that we share.” The disagreement is over whether these products contribute to the problem. CRN says Harvard’s Strategic Training Initiative for the Prevention of Eating Disorders (STRIPED) is a driving force behind the New York law and similar bills, and that STRIPED falsely claims these supplements cause eating disorders.

Opponents argue that the link is not there. Daniel Fabricant, PhD, president and CEO of the Natural Products Association, said, “there is not a single data point connecting the use of eating disorders and dietary supplements.” CRN points to a review by Susan J. Hewlings, Ph.D., R.D., which it says shows no link. CRN quotes her: “Risk factors for developing an eating disorder are multidimensional and complex and often co-occur with the diagnosis of depression or anxiety,” and “The literature indicates that eating disorder incidence is secondary to mental health conditions.”

CRN’s court challenge to the New York law is about speech: it argues the law raises First Amendment concerns by restricting how companies communicate truthful information about safe, legal supplements. Separately, in its request to veto AB 2030, CRN warned that the California framework, which lets courts weigh statements that “imply” these effects and how products are grouped in stores or online, could reach fiber and protein supplements, general wellness products and even multivitamins. CRN says that instead, restrictions should apply only to products the California Department of Public Health determines contribute to specified health conditions.

Two other proposals are not law. Michigan State Rep. Erin Byrnes drafted the Weight Loss Product and Minor Act, which, as a FOX 2 report noted, still had to come up for a hearing. Rep. Nick Langworthy’s Dietary Supplement Regulatory Uniformity Act, which Citizens for Health supports, would block states from layering their own labeling, age-restriction or sales requirements on supplements. The Natural Products Association says 20 states have had these age-restriction proposals in the past four years.

What does the research say about teens, supplements and eating disorders?

The claim that these products cause eating disorders is contested. Advocates point to STRIPED’s work, and the industry points to the Hewlings review. To check either claim, read the review or report itself and look at its date, the population it studied and how it measured eating disorders.

What should a parent or teen know about safety?

Whatever the policy debate, the safety points are clear. MedlinePlus, the U.S. National Library of Medicine’s health topic page, says MedlinePlus on dietary supplements that supplements do not have to go through the testing that drugs do. It advises telling your health care provider about any dietary supplements you use and not taking a bigger dose than the label recommends.

An FDA handout for health professionals, dated May 2022, says FDA guidance on supplement risks for patients that dietary supplements may contain ingredients that can have strong effects in the body. It adds that patients may experience harmful and even life-threatening consequences, especially if they use supplements with prescription or over-the-counter medications, take supplements instead of medications, combine supplements, or consume supplements in high doses. The same handout says products falsely marketed as dietary supplements can sometimes contain hidden pharmaceutical ingredients, and it names sibutramine, sildenafil, tadalafil and phenolphthalein as common examples.

If a teen you know is skipping meals, using pills to lose weight, or showing other changes in eating, bring it to a doctor or pediatric clinician rather than a supplement. For a broader look at how supplement evidence holds up, see our memory supplements evidence and safety guide.

What would show whether the law works?

The law was only recently signed, so there is no enforcement record to read yet. To judge whether it works, watch for these things:

• Enforcement. Cases and injunctions brought by the Attorney General, a county counsel or a city attorney under the penalty section.
• Store and online practice. Whether stores and delivery sellers use ID checks, database verification or adult signatures, and whether products are still shelved or grouped as weight-loss or muscle-building items.
• Health data. Peer-reviewed studies that track eating-disorder diagnoses or treatment among teens before and after the law starts. New York’s law was scheduled to start in April 2024, so its experience is one comparison point.
• Court outcomes. Whether New York’s law survives CRN’s challenge, and whether the U.S. Supreme Court takes up CRN’s petition.

What are the common mix-ups?

• “Diet pills” is not the same as supplements. The bill covers over-the-counter diet pills, which are drugs for which a prescription is not required, and dietary supplements. A prescription weight-loss medicine is not an over-the-counter diet pill under the bill’s definition.
• An ingredient on a label is not a ban. Creatine or green tea extract is a factor a court may weigh. The bill does not ban either one.
• Adults are not covered. The age limit applies only to people under 18.
• Earlier and proposed bills are not this law. AB 1341 was vetoed in 2022 and AB 82 stalled in 2024. The Michigan bill and the federal uniformity bill are proposals.
• “Drug” can mean a different topic. If you were searching for workplace drug-test rules, our california marijuana drug test employment law guide covers California workplace drug-test rights.

Who does this law affect?

• Buyers under 18 in California, who cannot buy covered products without a prescription.
• Parents and guardians, who may want to know what a teen can buy and how the prescription exception works.
• Retail stores, including pharmacies, grocery stores and other retail stores, and vendors that take orders by mail, phone, email or internet.
• Delivery sellers and online retailers, who must verify age or require an adult signature.

What should I check before I act?

• If you run a store or ship orders, read subdivisions (b) and (c) of the bill, and ask a California attorney or the Attorney General’s office how it applies to your products.
• Check the start date on the California Legislative Information site, leginfo.legislature.ca.gov, where the bill is tracked.
• If a teen has a weight or muscle concern, talk to the teen’s doctor before buying any product.
• Read the label of any product in question. Under FDA guidance, companies that manufacture or market dietary supplements are responsible for ensuring that product labels are truthful and not misleading.
