September 13, 2023

Identifying whether Pepto Bismol is vegan or not can be a challenging endeavor.

This difficulty often arises because manufacturers tend to obscure the nature and source of their ingredients.

Fear not, dear reader, for this article aims to unveil the truth and support you wholeheartedly in your commendable vegan lifestyle.

Is Pepto Bismol Original Liquid Vegan?

No, Pepto Bismol is not vegan. Pepto Bismol may not be considered entirely vegan due to the presence of magnesium stearate in its formula. Magnesium stearate is an ingredient whose animal-derived or plant-derived origin is uncertain, making it potentially non-vegan.

Is Pepto Bismol Cruelty-Free?

No, Pepto Bismol is not cruelty-free.

The reason for this lies in the ingredients used in its formulation. Specifically, the ingredients D&C Red No. 27 aluminum lake and FD&C Red No. 40 aluminum lake are synthetic dyes that are often tested on animals, making them non-cruelty-free ingredients. The sweetener mannitol is also routinely tested on animals.

What Is Pepto Bismol Made Of?

Pepto Bismol, a popular remedy for an upset stomach, is made up of a combination of active and inactive ingredients. Here’s a breakdown:

  • Adipic acid
  • Calcium carbonate
  • D&C Red No. 27 aluminum lake
  • FD&C Red No. 40 aluminum lake
  • Flavor
  • Magnesium stearate
  • Mannitol
  • Povidone
  • Saccharin sodium
  • Talc

Adipic Acid

Adipic acid is an organic compound primarily used as a food additive. It’s synthetic and does not come from animal sources, making it vegan.

Calcium Carbonate

Calcium carbonate is a mineral used as an antacid to relieve heartburn and stomach acid. It’s derived from the earth’s crust and is vegan-friendly.

D&C Red No. 27 Aluminum Lake & FD&C Red No. 40 Aluminum Lake

Both are synthetic dyes used for coloring. Although they are technically vegan, their cruelty-free status is questionable due to probable animal testing.


The term “flavor” is ambiguous. It can be derived from both plant and animal sources, making its vegan status uncertain.

Magnesium Stearate

Magnesium stearate is a salt derived from stearic acid. It can be sourced from both plants and animals, so its vegan status is not always clear.


Mannitol is a type of sugar alcohol. It’s synthetic and considered vegan, but it is tested on animals, so keep that in mind.


Povidone is a synthetic polymer. It’s vegan because it doesn’t come from animal sources.

Saccharin Sodium

Saccharin sodium is an artificial sweetener. It’s synthetic and considered vegan.


Talc is a mineral used in various products. It’s vegan-friendly as it’s sourced from the earth.
