Are Fiber One Bars Vegan and Cruelty-Free? The Not-So-Friendly Truth

July 28, 2023

Trying to figure out if Fiber One Bars are vegan can be difficult.

Makers of granola and protein bars often hide their ingredients behind vague terms such as “natural flavors,” and even if they do provide a full list of ingredients, it can be hard to tell if those ingredients are vegan.

To ensure that you are only eating food that aligns with your vegan diet and lifestyle, I’ve looked into the ingredients and production processes of Fiber One Bars.

Here’s what I found out.

Are Fiber One Bars Vegan?

No. Fiber One Bars are not vegan.

Fiber One is a line of products manufactured by General Mills. The line includes breakfast cereals, granola bars, protein bars, and other snacks.

Fiber One Bars are one of Fiber One’s most popular varieties. Sadly, they are unsuitable for vegans. This product contains whey protein isolate—a milk derivative—and refined sugar.

A dairy product like whey is always a no-go for vegans.

Sugar is technically vegan, but most refined sugars are processed using animal bone char. Bone char is a black, porous material made from the bones of cattle. Unless the sugar is specifically labeled “raw,” “organic,” or “unrefined,” it’s likely not vegan.

So, if you’re looking for vegan protein bars, Fiber One Bars are not the right choice for you.

Fortunately, there are many other snack bar options on the market that are both vegan and delicious.

Are Fiber One Bars Cruelty-Free?

No. Fiber One Bars are not cruelty-free.

Fiber One Bars are not tested on animals at any point in their production. However, some varieties contain artificial colors, which are routinely tested on animals to ensure their safety for human consumption.

Animal testing is an outdated and inhumane practice that causes immense suffering. The practice leaves innocent animals disfigured, maimed, or dead. Surely there are other methods to test the safety of food additives.

Fortunately, many companies have stopped using animals in their product testing and are looking for humane alternative testing methods.
