California Proposition 65 Explained: What the Warning Really Means
Let’s Talk About That California Proposition 65 Warning
If you’ve ever flipped over a product and seen the California Proposition 65 Warning, you're probably wondering exactly what it means...
Cancer? Birth defects? Reproductive harm?
Yeah… that’s not something any of us want to ignore.
So let’s break this down.... because this label shows up on a lot of products, and it doesn’t always mean what people think it means.
What Proposition 65 Actually Is
Here’s the definition straight from California’s website:
“Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or released into the environment.”
When you see that label, you probably are immediately worried/concerned like I was when I first noticed this label.
But what most people aren't told is how broad and generalized this warning really is.
That List Is… Huge
California maintains a list of over 900+ naturally‑occurring and synthetic chemicals that fall under Prop 65, and it gets updated every year.
This list includes:
➡️ Certain heavy metals that naturally occur in soil
➡️ Compounds from tobacco smoke and exhaust
➡️ Chemicals formed during cooking or processing
➡️ Even substances found in some foods and plants
It’s actually a really useful list but not necessarily because everything on it should be avoided entirely, but because it can help you understand what contaminants exist and where caution might be neccessary.
Why You See This Label Everywhere.....
If you’re paying attention, you’ll notice this warning on:
- Food packaging
- Supplements
- Cookware
- Furniture
- Household cleaners
- Building materials
- Even coffee shops and parking garages
Here’s what’s important to know:
Proposition 65 does not consider:
- How often you use a product
- Route of exposure (ingestion vs skin vs inhalation)
- Actual exposure levels
- Whether a company tests and stays under safe exposure limits
Because of this, many companies choose to add the warning even if their product tests below safety thresholds, simply to avoid legal risk.
⭐️ A Real‑Life Example: Herbal Tea 🍵
This is one of my favorite examples.
Herbal teas, even USDA organic ones, can contain naturally occurring heavy metals because plants absorb minerals from the soil where they grow.
So what do many companies do?
They slap a Proposition 65 warning on the label as an extra precaution.
That does not automatically mean the tea is unsafe.
What I personally want to know instead is:
- Is the tea USDA organic?
- Do they third‑party test for heavy metals?
- Are their levels within safe exposure guidelines?
- Is this company transparent and committed to safety?
Those answers tell me way more than the warning label alone.
Context Matters A LOT ‼
This is where we have to pay attention
If you saw a Proposition 65 warning on:
➡️ A fast‑food wrapper: 🚩🚩🚩 that's way more concerning to me than.....
➡️A loose‑leaf, USDA organic tea that’s third‑party tested
Same warning. Very different product quality, sourcing, and safety practices.
A Few Important Facts Most People Don’t Know
• Prop 65 is California‑specific. You’ll often see the warning nationwide because it’s easier for brands to use one label
• There are average exposure levels. Many products fall well below those limits but still carry warnings
• The warning often reflects potential exposure, not actual harm
• Labels are not required to state which chemical triggered the warning or how much is present ‼️
All of that contributes to over‑labeling.... which unfortunately can make it harder for consumers to tell when there’s a REAL concern.
My thoughts on California Prop 65 Warning
Yes, this warning can be concerning.
But it should never be interpreted in isolation.
When I see it, I consider:
- What type of product is this?
- How is it used?
- Is it ingested, inhaled, or just touched?
- How often would someone be exposed?
- Does the brand test their products?
- Are they transparent about safety?
This is why being an informed consumer matters more than being a fearful one.
The goal isn’t perfection...... it’s discernment.
The Proposition 65 label exists to inform... Which I actually appreciate because I'm ALL about being informed. BUT it's up to us to be able to make our own decisions and have all the gathered data to make those decisions.
So all in all:
✅ Ask questions
✅ Look for transparency
✅ Choose brands that take safety seriously
Just remember, context, quality, and exposure matter.
I hope this helped clear up some of the confusion around this label 🤍 As always, my goal is to give you information so YOU can decide what feels right for your family.
