## Key points

- California will restrict some supplement sales to under-18s from 2027.
- The law covers products marketed for weight loss or muscle building.
- Sellers could face fines of up to $500 per violation.

## Summary

California Governor Gavin Newsom has signed a law restricting the sale of certain weight-loss and muscle-building supplements to people under 18. Taking effect on 1 January 2027, it aims to limit young people’s access to products that may be medically unapproved, misleadingly labelled or contaminated.

The law applies to products marketed for weight loss or muscle building, and courts may consider ingredients such as creatine and green tea extract when deciding whether a product is covered. It does not ban all creatine products, and minors with a prescription are exempt; sellers could face civil fines of up to $500 per violation. The announcement cites research that nearly one in 10 adolescents have used these products, while industry critics say the law’s scope is unclear and supporters argue it protects young people from deceptive claims.
