Does Ninja Blender Cause Cancer?

There is a lot of debate on “does Ninja blender cause cancer?”.

If you look at the bottom of a Ninja Ultima blender box, you’ll notice a warning that says, “WARNING: This product contains chemicals (including lead) known to the State of California to cause cancer and birth defects or other reproductive harm”.

Ninja claims that this warning has always been on their blender, but users claim they didn’t notice it until recently.

So which is it? Is the Ninja blender a health hazard, or is it perfectly safe? In this article, we will take a closer look at the evidence surrounding this debate and try to get to the bottom of it.

Why Does Ninja Blender Have A Prop65 Warning?

Because they may cause cancer and/or birth defects or other reproductive damage, some household appliances might contain chemicals on the Proposition 65 list. Businesses must evaluate whether they need to provide a caution about significant exposure to listed chemicals under Proposition 65. This warning is intended to inform the public about their exposure to chemicals that may be in their home or workplace.

If a product meets the definition of a “covered” product under California’s Safe Drinking Water and Toxic Enforcement Act (commonly called “Proposition 65”), then that product must carry with it a warning advising consumers that the product contains chemicals on the list. A covered product is defined as an “item containing one or more chemicals subject to Proposition 65”.

Ninjas are considered personal care items. All ingredients found in Ninja’s products are listed on their labels, including lead. Ninja claims they have always had this label on their blender, but users claim they didn’t notice it until recently.

However, some online articles say that you won’t find prop65 warnings for certain household appliances.

Whether or not the Ninja blender meets the requirements of Proposition 65, it is clear that Ninja believes their product contains chemicals that cause cancer and/or birth defects or reproductive damage. It also makes sense that they put a warning on their products to be up-front with consumers about their ingredients.

Does Ninja Blender Cause Cancer?

The bottom of a Ninja Ultima Blender box says it contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Many people are concerned about whether this is true.


One chemical that was found in Ninja blenders during an investigation by NBC4 Southern California was lead, which is also known to cause cancer.

The problem with this chemical being in Ninja blenders seems pretty straightforward: if there’s no lead in the chrome plated metal that makes up the blade, then there should be no lead at all in your drink. Additionally, health experts have pointed out that even trace amounts of lead are enough to pose a serious risk for children under 6 and pregnant women.

Lead used in the chrome plating of the blade is one source of lead in Ninja Blenders, but it isn’t the only source.

FDA has set limits on how much lead can be present in food and beverages, and these limits are 5 ppm (parts per million) for candy intended for children under six, and 10 ppm for other foods. A California health agency found that a serving of Ninja Kitchen strawberry banana ice cream was above this limit; nine times higher than allowed by law.

So there’s definitely no denying that unsafe levels of lead were found in some Ninja blenders – at least, until you look at their manufacturer’s response to this finding: “the amount was well below FDA ‘action levels’ and all products are safe to consume.”

So it seems that, at least according to the manufacturer, even if there is lead in your blender, it’s still perfectly harmless.

Although this seems like a pretty convincing argument, you can’t just take their word for it; especially since they also claim that lead was only found in trace amounts. Even if you agreed with them that the lead levels were “well below FDA ‘action levels'” (which might even be true), you would still need more information about how much of the other chemicals found in Ninja blenders actually pose a risk.

For example, do they cause cancer or other diseases? Do they vary by specific product?

Causes Cancer/Other Diseases

There is no evidence that the ingredients in Ninja blenders cause cancer. As we mentioned earlier, they only found lead in some products, and if there’s lead in your blender you’re probably not going to be drinking it anyway.

However, just because these substances haven’t been proven to cause cancer doesn’t mean they’re completely safe. We don’t know what the long term effects of consuming them might be – especially on a regular basis.

Just another thing to consider…

So at this point, it seems like the jury is still out on whether or not Ninja blenders can cause cancer. They’ve found unsafe levels of a chemical known to be carcinogenic (lead), but since the manufacturer has responded by saying the levels are “well below FDA ‘action levels,'” it seems like manufacturers aren’t too concerned about the possibility.

But when you consider that there is no evidence that these chemicals cause cancer in the first place, there really isn’t much reason to be too worried about them.

Is The Ninja Blender A Health Hazard?

Because there are no reports to prove either way whether the Ninja blender causes cancer, we cannot determine if this blender is a health hazard .

It’s more than likely, though, that the chemicals included in the Ninja blender are safe. While there are no reports on whether or not it causes cancer, the chemicals in the blender are listed on the product so consumers can make their own decisions.

If you have any concerns about Ninja’s health claims, be sure to speak with your doctor before purchasing a Ninja Ultima blender.

Although some users claim they didn’t see the warning until recently, this may simply mean that they were not aware of what Proposition 65 is – which does NOT indicate that ninja blenders cause cancer.

The Bottom Line

If you’re still not convinced (and want to err on the side of caution), then don’t buy Ninja blenders. Or, at least make sure to clean your blender very well after every use and get rid of any chunks.

So does this mean Ninja blenders can cause cancer? We really don’t know for sure, but there’s more reason to be cautious than not – especially since we have no real idea what prolonged exposure to these chemicals might do to your body.
