Understanding California's Proposition 65
California's Safe Drinking Water and Toxic Enforcement Act of 1986, known as Proposition 65 (Prop 65), mandates that businesses inform Californians about significant exposures to chemicals causing cancer or reproductive harm. Prop 65's warning thresholds are often much stricter than federal or international safety standards, requiring a warning for minimal exposure levels deemed safe elsewhere. The law lists a wide range of substances, both natural and synthetic.
The Plant-Based Connection: Naturally Occurring Heavy Metals
Huel uses plant-based ingredients like oats, flaxseed, and brown rice, which can naturally contain trace heavy metals absorbed from soil and water where they grow. This is normal and not a sign of poor quality. Metals like cadmium are in nuts and spinach, and lead is in many common foods, typically at low, safe levels.
Why Huel Received a Warning
In 2021, the Environmental Research Center (ERC) alleged Huel products contained lead and cadmium exceeding California's limits, requiring Prop 65 warnings that were not present. To settle and comply, Huel agreed to display the warning on products sold in California.
The Legal Outcome
Huel agreed to display Prop 65 warnings in California based on its testing, acknowledging the need to comply with the state's low-level disclosure requirements. This indicates compliance with the law, not that the products became unsafe. Warnings for California online purchases appear at checkout.
Are Huel Products Actually Safe to Consume?
Huel maintains the safety of its products, adhering to broader international safety guidelines.
Huel's Safety and Testing Protocol
- Regular independent testing: Huel tests for heavy metals and contaminants to meet US and EU standards.
- Accredited manufacturing: Production occurs in FDA-registered, GFSI-accredited facilities following cGMP.
- Levels below concern: Testing confirms heavy metal levels are well below safety limits, including the strictest global ones. Arsenic and mercury are usually undetectable.
The Prop 65 warning is specific to California's law and doesn't mean Huel products are unsafe by objective health standards. It reflects the state's very low warning threshold.
Prop 65 Warning vs. Actual Health Risk
A Prop 65 warning informs about potential exposure but doesn't necessarily mean a health hazard. Heavy metal levels in Huel are comparable to or lower than those in many common foods. A 2014 FDA study showed heavy metals in many grocery items, many of which would also require a Prop 65 warning. Companies sometimes add warnings to avoid legal issues, even if they believe their product is safe. The key difference is that Prop 65 takes a very conservative approach, while most other health bodies assess actual exposure and risk.
Comparison: Prop 65 vs. Other Food Safety Standards
| Standard / Regulator | Proposition 65 (California) | U.S. Federal Regulations (FDA) | European Food Safety Authority (EFSA) |
|---|---|---|---|
| Threshold Level | Extremely low, often based on potential exposure over a lifetime, leading to warnings for trace amounts. | Based on toxicological data to set limits that protect public health with a wide margin of safety. | Sets maximum levels based on scientific evidence of what is safe for consumers, taking into account exposure from all food sources. |
| Warning Trigger | Any detectable amount of a listed chemical that exceeds a specific, conservative threshold. | Requires action only if contamination poses a significant public health risk or exceeds set limits. | Requires action if a substance exceeds established Maximum Levels (MLs) for specific foods. |
| Focus | Right-to-know legislation that requires disclosure, regardless of actual risk. | Focuses on actionable regulatory limits to prevent harm and ensure food safety. | Concentrates on setting science-based standards to protect consumers across the EU. |
| Context | Often applies to naturally occurring substances, requiring a warning on many commonplace items. | Considers overall dietary intake and total exposure when evaluating risk. | Accounts for dietary exposure and consumer habits when determining acceptable levels. |
What This Means for Consumers
A Prop 65 warning on Huel is a notification, not an alert of danger. The low, natural levels of heavy metals in Huel are within global safety standards. For most, it's a technical compliance detail. Those sensitive to chemicals can use the warning to make informed choices, which is the law's intent.

Conclusion
Huel displays a Prop 65 warning due to trace heavy metals like lead and cadmium naturally present in its plant ingredients, as required by California's strict regulations after a legal settlement. Huel states its products are rigorously tested and meet international safety standards; the warning is primarily for legal compliance in California.
