What is California's Proposition 65?
California's Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a state law designed to protect California residents and the state's drinking water sources from harmful chemicals. It requires businesses to provide a "clear and reasonable warning" if a product exposes consumers to any of the approximately 900 chemicals on the state's list that are known to cause cancer, birth defects, or other reproductive harm. The law does not ban these chemicals but instead gives consumers the right to know about potential exposure, allowing them to make informed decisions.
The Cause of the Warning: Naturally Occurring Heavy Metals
The Prop 65 warning on Vital Proteins collagen products is primarily a result of the presence of naturally occurring trace heavy metals, most notably lead and cadmium. These metals are ubiquitous in the environment, found in soil, water, and air. When animals (in this case, grass-fed, pasture-raised cows) consume food and water, these metals can accumulate in their bodies, particularly in their bones and connective tissues. Since collagen is extracted from these animal parts, it can retain trace amounts of these contaminants.
Independent studies and a 2017 notice of violation filed against Vital Proteins confirm that some of their products contained detectable levels of lead and cadmium. It is important to understand that this is not unique to Vital Proteins; heavy metals can be present in many animal-sourced and even plant-based products, depending on the environment in which they are grown.
Prop 65 vs. Federal Safety Standards
Perhaps the most confusing aspect of the Prop 65 warning is how it compares to federal safety regulations. California's standards are far more rigorous than those set by federal bodies like the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA). The warning is often triggered by chemical levels thousands of times lower than levels deemed safe by federal agencies.
Comparison of Lead Exposure Standards
The difference in standards is stark, especially concerning lead. The following table illustrates the vast gap between California's Prop 65 warning threshold and the FDA's established safety level:
| Standard | Lead Exposure Threshold | Context |
|---|---|---|
| California Prop 65 | 0.5 mcg per day (reproductive harm) | A warning is required for any product exceeding this extremely low level, regardless of risk. |
| FDA Interim Reference Level (IRL) | 12.5 mcg per day | The FDA’s daily safety limit, significantly higher than the Prop 65 warning trigger. |
This means a product can be labeled with a Prop 65 warning for lead even if it contains a tiny fraction of the amount considered acceptable by the FDA for daily consumption. For example, even some dark chocolate and grape juice naturally contain enough lead to exceed California's strict threshold, but this doesn't mean they are unsafe to consume. For Vital Proteins, the warning signifies compliance with California's law, not necessarily an immediate health hazard according to federal standards.
What This Means for Your Nutrition Diet
For consumers, seeing a Prop 65 warning on a trusted product can be unsettling. However, it's essential to put it in context. The warning is a legal requirement based on highly conservative standards, and the trace amounts of heavy metals present are often not considered a significant health risk by national health organizations. Instead of causing panic, the warning serves as a prompt for consumers to be aware and to research their products.
Making Informed Supplement Choices
If you are concerned about heavy metals in your supplements, several strategies can help you make a more informed and confident choice:
- Prioritize Third-Party Testing: Look for brands that utilize and display results from independent third-party testing services, such as NSF International, USP, or others. Many reputable brands provide transparent lab results, often called Certificates of Analysis (COAs), verifying the absence of harmful levels of contaminants.
- Research Sourcing: Choose products from brands that source their ingredients responsibly from clean, well-monitored environments. For bovine collagen, look for grass-fed and pasture-raised sources. For marine collagen, seek wild-caught sources from clean waters.
- Consider Vegan Alternatives: For a guaranteed animal-free option, some brands offer vegan collagen alternatives made from plant-based ingredients. These are processed differently and are not subject to the same contamination risks.
Conclusion
In summary, the Prop 65 warning on Vital Proteins collagen is not a sign of a dangerous product, but rather a consequence of California's uniquely stringent and cautious consumer protection law. Trace amounts of heavy metals like lead and cadmium can naturally occur in animal-sourced ingredients and trigger the warning, even when the levels are far below federal safety standards. Ultimately, the warning empowers consumers with information, allowing them to decide what level of risk is acceptable for their personal health and nutrition diet. For maximum peace of mind, prioritize transparency by choosing brands that conduct and publish third-party testing results.

The Role of Lifestyle Factors
While supplement choice is part of a healthy nutrition diet, it's important to remember that overall lifestyle factors significantly influence your health. For instance, consuming a varied and whole-food-rich diet naturally minimizes reliance on any single source of nutrients, including collagen. Ensuring adequate intake of Vitamin C and zinc, which are crucial for the body's natural collagen production, can be achieved through a balanced diet of citrus fruits, leafy greens, nuts, and seeds. A healthy lifestyle, including avoiding excessive alcohol use, not smoking, and getting enough sleep, will also have a far greater impact on your overall health than the minute trace elements that trigger a Prop 65 warning.
Evaluating Product Purity: A Checklist
When evaluating collagen products, it's helpful to have a checklist to ensure you're choosing a high-quality supplement that aligns with your health goals. This extends beyond just checking for a Prop 65 warning:
- Source: Is it grass-fed bovine, wild-caught marine, or cage-free chicken? The source can indicate the likelihood of contamination.
- Form: Is it hydrolyzed collagen (peptides)? This form is easier for the body to absorb.
- Additives: Does the product contain unnecessary fillers, binders, or artificial sweeteners? A simple, clean product is often better.
- Testing Transparency: Does the company openly share third-party test results (COAs) for heavy metals and other contaminants?
- Certifications: Does it have certifications like NSF or GMP, which indicate adherence to high manufacturing and safety standards?
By following these guidelines, you can navigate the complexities of supplement labels and make choices that best support your individual health and nutrition needs.
