Private label, white label, custom formulation, and co-packing compared: cost, timeline, NPN, formula ownership, and which path fits a first supplement launch.
Supplement manufacturing in California
The largest US supplement market, served by California GMP facilities.
LumaNutra partners with cGMP-certified supplement manufacturing facilities in California, serving supplement brands across Los Angeles, the Bay Area, San Diego, Orange County, and the wider California wellness scene. Full DSHEA compliance, Prop 65 work done properly, and access to premium West Coast manufacturing.
The California market
California is the single largest supplement consumer market in the United States and home to many of the country's most innovative wellness, sports nutrition, longevity, and plant-based brands. Los Angeles, San Francisco, San Diego, and Orange County dominate US DTC launches, influencer-led brand building, and premium retail distribution. Manufacturing in California lets brands stay close to their customer base, their creative and marketing teams, and their investors. It also gives brands access to the Port of Los Angeles / Long Beach for international ingredient sourcing.
US regulatory context (DSHEA)
California supplements are regulated federally under the FDA's Dietary Supplement Health and Education Act (DSHEA), with California-specific layers including Proposition 65 (requiring warning labels for products containing listed chemicals above threshold), California Department of Public Health processed food registration where applicable, and strict Attorney General enforcement of labeling and advertising claims. California is also the US jurisdiction most likely to see private plaintiff litigation over supplement claims, so claim substantiation and label accuracy are especially important.

Why California brands work with LumaNutra
The hidden cost of manufacturing in California isn't the facility rate. It's compliance. Prop 65, aggressive consumer protection enforcement, and plaintiff attorneys looking for labeling violations all create real downside risk for brands that get it wrong. We handle facility selection, heavy-metal and contaminant testing, compliant label design, and structure-function claim review so the product you ship holds up if someone comes looking. Our California network supports flexible volume as you enter the market, with capacity to scale as you grow.

Frequently asked questions
Proposition 65 applies to any supplement sold to California consumers, regardless of where it was manufactured. California-made products face the same obligation. The practical implication is that supplement brands should ensure heavy-metal testing is completed to Prop 65 thresholds and that any listed chemicals at or above safe harbor levels carry the required warning.
California proximity matters for brands whose customers, marketing teams, influencers, and investors are all in-state. The operational benefit of same-day facility visits, faster iteration on launches, and integrated West Coast fulfillment often outweighs the additional compliance lift. LumaNutra handles the compliance work so brands can focus on brand building.
Our California network supports MOQs starting at 2,000 units for most standard dosage forms. Specialty formats (gummies, softgels, functional beverages) may carry higher minimums depending on facility capabilities.
Yes, but the product must meet Health Canada NHP requirements. Including a valid NPN for the product and (where applicable) a Canadian Site Licence holder for packaging or importing.
