California does not have a general creatine ban today. It has a current, narrow rule for certain steroid-precursor and ephedrine-alkaloid supplements, plus a broader under-18 sales law that was enacted in September 2026 but does not take effect until January 1, 2027. For creatine, the exact product label, muscle-building marketing, and how the store presents it will matter once that future law begins.
If you are sorting through a tub, gummy, or pre-workout label, start with the rule that applies on the date you plan to buy or sell. Creatine monohydrate evidence can help with the ingredient question; this page answers the California sales-rule question.
What California rule applies to creatine right now?
California’s current statute, Health and Safety Code 110423.2, makes it a misdemeanor to sell, transfer, or furnish specified supplements to a person under 18. Its listed products include supplements containing an ephedrine-group alkaloid and specified steroid precursors, including dehydroepiandrosterone (DHEA).
Creatine is not listed in that current provision. The statute also says a seller must request valid identification from someone who reasonably appears to be under 18 when buying one of the listed products. That is a different rule from AB 2030.
| Rule | Status on October 9, 2026 | What it covers | What it means for creatine |
|---|---|---|---|
| Health and Safety Code 110423.2 | Current | Specified ephedrine-alkaloid and steroid-precursor supplements sold to people under 18 | Creatine is not one of the listed substances. |
| AB 2030, Chapter 720 | Enacted future rule | Under-18 sales of OTC diet pills and supplements labeled, marketed, or represented for weight loss or muscle building | Creatine is a factor a court may consider, alongside the product’s claims, marketing, and placement. |
When does California’s new supplement sales law start?
Governor Newsom’s September 28 announcement confirms that he signed AB 2030 that day. The chaptered act was also approved and filed on September 28, 2026.
That is the enactment date, not the start date for routine enforcement. AB 2030 contains no urgency clause. Under Article IV, Section 8 of the California Constitution, a regular-session statute generally takes effect on January 1 after the relevant 90-day period. For AB 2030, that means January 1, 2027.
| Date | What happened | Why it matters |
|---|---|---|
| September 28, 2026 | AB 2030 was approved and filed as Chapter 720. | The law was enacted. |
| October 9, 2026 | This guide’s legal reference date. | AB 2030 is enacted, but its new under-18 sales rule has not started. |
| January 1, 2027 | AB 2030 takes effect. | The new scope and delivery requirements become the rule to check. |
Update trigger: Recheck the chaptered act and any California guidance before January 1, 2027, and again when you are deciding about a specific product or sale date.
Can you buy creatine under 18 in California after January 1, 2027?
AB 2030 does not label every creatine product as automatically covered. It applies to a dietary supplement that is labeled, marketed, or otherwise represented for weight loss or muscle building. The act lets a court consider whether a product contains creatine, but it also directs attention to claims about weight, fat, appetite, metabolism, muscle, or strength, plus product grouping, signs, tags, displays, ads, and website placement.
So an under-18 creatine question after January 1, 2027 is a product-specific question. Read the exact Supplement Facts panel and the exact muscle- or strength-related marketing. Do not rely on a broad label such as “legal steroids”; that phrase does not tell you whether a particular product falls inside AB 2030’s definition.
The act does not apply to a person under 18 with a prescription for a covered over-the-counter diet pill or dietary supplement. It also expressly does not apply to people 18 and older.
What changes for online creatine orders?
Beginning January 1, 2027, an online retailer or other delivery seller handling a covered product cannot sell, deliver, or cause delivery to a California buyer under 18. The act gives delivery sellers two defined paths: verify the buyer’s full name, birth date, and residential address through a qualifying commercially available database, or ship by a method requiring an adult age 18 or older to sign and show valid government-issued photo identification at delivery.
The database must be primarily built from government-source data and cannot be controlled or changed by the delivery seller. These are California’s own delivery options. They are not a reason to import another state’s shipping rules into a California order.

Legal category and jurisdiction card
A product can be sold as a supplement, subject to an age restriction, and still be prohibited by a sports organization. Use this card to record what a current official source says about one exact product and one activity. It does not issue legal clearance.
How to use this card
- Copy the exact current product name and complete label. Identify Supplement Facts, Drug Facts, or a prescription drug instead of relying on a marketing phrase.
- Choose the activity you need answered: sale, delivery, purchase, possession, or sports participation. Record the state and date.
- Read the current official rule and its definition. Check whether the ingredients, format, and marketing fit that definition.
- Record whether the source is current law, an enacted future rule, a proposal, or an unresolved question. Do not treat an introduced bill’s effective-date sentence as enacted law.
- Keep the conclusion narrow. For a personal product or business decision that remains uncertain, use the recorded facts to obtain qualified advice.
| Use one record per product, rule, or notice | Record 1 | Record 2 | Record 3 | Record 4 | Record 5 |

Worked example: fictional California shopper
Fictional shopper: Alex, age 17, is considering a hypothetical creatine powder marketed for muscle strength from a California online seller on October 9, 2026.
- Exact product, form, flavor, and label date: Hypothetical Strength Powder, unflavored powder; illustrative label only.
- Ingredients and marketing: Creatine monohydrate; hypothetical muscle-strength marketing.
- State and action: California; online purchase and delivery.
- Age context: Under 18.
- Official source and date checked: AB 2030, Chapter 720; checked October 9, 2026.
- Rule status: Enacted future rule; effective January 1, 2027.
- What the source establishes: Creatine and muscle-strength marketing are factors a court may consider under AB 2030. On this date, the new rule has not started.
- What remains product-specific: The exact label, product presentation, sale date, and seller handling should be checked before relying on the card.
What this card can and cannot tell you
For this card, mark a provision as a current rule only when it applies on the date checked. A future rule is enacted but not yet effective. A proposal may never become law. An unresolved question means the source or product facts do not support a narrow conclusion yet.
This California screen addresses specified supplement and diet-pill sales questions. It is not a complete review of possession rules, local ordinances, sports eligibility, every ingredient, or a particular seller’s checkout system. Keep the product name, full label, marketing, state, action, and date together. That is the cleanest next step before you decide what to do.
