What OEHHA's 2026 Prop 65 omnibus changes mean for supplement brands
By Jake, founder · Published · Source dated
OEHHA released draft Prop 65 changes on July 1, 2026. The naturally occurring exemption could narrow for chemicals extracted or concentrated from plants, even without chemical alteration. Internet-purchase warnings and QR codes are also covered. Comments open July 22–September 8, 2026.
What changed in the Prop 65 omnibus draft?
The Office of Environmental Health Hazard Assessment (OEHHA) published a pre-rulemaking notice on July 1, 2026, for an omnibus package of potential amendments to Proposition 65 regulations. The notice states that draft regulatory text and presentation slides were made available, with the draft regulatory language dated July 22, 2026.
According to the notice, OEHHA will host a workshop on July 30, 2026, to discuss potential regulatory amendments. The workshop will be both in-person at CalEPA Headquarters in Sacramento and online via Zoom webinar. The notice lists the draft regulatory text, presentation slides, and public comment instructions as available downloads.
What does the draft say about the naturally occurring exemption?
The provided source text does not contain the specific language of the proposed changes to the naturally occurring exemption. The summary provided by the requesting party indicates that one change narrows the naturally occurring exemption: a chemical extracted or concentrated from a plant can now count as human-caused even if it wasn't chemically altered.
Because the source text does not include the draft regulatory language, we cannot confirm the exact wording, scope, or examples. The source only confirms that the omnibus package includes potential amendments and that a workshop will discuss them. Brand owners should review the actual draft regulatory text posted on OEHHA's website for the precise proposal.
What other topics are in the omnibus package?
The notice does not describe the topics covered by the draft regulatory text. The requesting party's verified summary states that other changes touch internet-purchase warnings and add QR codes as an approved warning method. However, the source text itself does not mention these topics.
Since the source text is thin on substantive details, we cannot provide further specifics on internet-purchase warnings or QR codes. To understand the full scope of potential amendments, review the draft regulatory text dated July 22, 2026, and the presentation slides from August 5, 2026, both available on OEHHA's website.
Who does this affect?
The source text does not specify who is affected by the proposed amendments. Given the nature of Prop 65, businesses selling products in California could be impacted, particularly those with botanical extracts or online sales. The verified guidance line suggests reviewing whether the naturally-occurring and internet-purchase/QR-code warning changes affect your labeling if you sell botanical-extract products or ship into California.
Again, because the source text lacks details, we cannot confirm the exact applicability. The workshop on July 30, 2026, is open to the public and may provide clarity on who and what products are covered by the potential amendments.
What are the key dates?
The notice lists three key dates: July 1, 2026, for the pre-rulemaking notice; July 22, 2026, for the draft regulatory language; and August 5, 2026, for the pre-rulemaking presentation slides. Public comments are open from Wednesday, July 22, 2026, at 12:00 pm to Tuesday, September 8, 2026, at 12:00 pm.
The workshop will be held on Thursday, July 30, 2026, from 10:00 am to 11:30 am Pacific Time. The in-person location is the CalEPA Headquarters Building, Training Room 1 East/West, 1001 I Street, Sacramento, CA 95814. Online participation is available via Zoom webinar, and registration is required.
What should a supplement brand do now?
A sensible step is to review the draft regulatory text dated July 22, 2026, and the presentation slides, available on OEHHA's website. Compare the proposed language to your current labeling and warnings, especially if you sell botanical extracts or ship into California.
Consider attending the July 30 workshop or watching the recording if one is posted. If you have concerns or comments, prepare and submit them before the September 8, 2026 deadline. Keep records of your review, as a document reviewer may later ask how you assessed the impact of these changes.
