What part of a pig is in toothpaste?

What’s Really in Your Toothpaste?

It’s a question that might make you pause mid-brush: what part of a pig ends up in toothpaste? The short answer? Not a piece of meat, but a byproduct that helps give toothpaste its smooth consistency—glycerin.

Glycerin, also known as glycerol, is a common ingredient in many personal care products, including toothpaste. It helps retain moisture and provides that familiar smooth texture we expect when we squeeze it onto our brush. While glycerin can come from plant sources or synthetic processes, it can also be derived from animal fat—including pigs. Specifically, it's often a byproduct of rendering animal bones and fat, which is then processed into a usable form.

However, not all toothpaste contains animal-derived glycerin. Many brands now use plant-based or synthetic glycerin to cater to vegans and those with religious or dietary restrictions. If you're concerned, checking the label or opting for certified vegan or halal products can give you peace of mind.

Still, the idea of pig fat in everyday products isn’t as unusual as it sounds. Animal byproducts are used across industries—from food to cosmetics—often in ways consumers don’t expect. Awareness is growing, though, and more companies are responding with transparent labeling and alternative formulations.

So while yes, traditional glycerin can come from pigs' bone fat, it's not a universal practice. With a little research, it’s entirely possible to find a toothpaste that aligns with your values—without sacrificing that fresh, clean feel.
