Is Lab Meat Vegan? The Surprising Truth Behind Cultivated Protein

December 20, 2025 •

4 min read

According to The Vegan Society, the organization that coined the term 'vegan', cultivated or lab-grown meat is not vegan and likely never will be. While designed to eliminate animal slaughter, the production process still relies on animal cells and, historically, other animal-derived inputs. This critical distinction challenges common assumptions and raises complex questions for ethically-minded consumers.

Quick Summary

Cultivated meat uses animal cells for production, meaning it is not vegan, as confirmed by The Vegan Society. Although it reduces the need for slaughter, its dependence on animal inputs, even in the cell collection phase, disqualifies it under the strict definition of veganism.

Key Points

Not Vegan: Lab meat is not vegan because its production relies on a starter culture of animal cells, as confirmed by organizations like The Vegan Society.
Animal Inputs Required: The process requires obtaining a sample of animal cells, often through a biopsy from a living animal, which constitutes animal use.
FBS Historically Used: Early production methods frequently used Fetal Bovine Serum (FBS), an animal byproduct, though many companies now develop animal-free growth mediums.
Focus is Cruelty-Reduction, Not Veganism: Cultivated meat aims to provide a slaughter-free alternative to traditional meat eaters, not necessarily a new vegan product.
Ethical Debate Exists: There is nuance within the vegan community, with some supporting the technology for its harm-reduction potential, while purists reject any form of animal exploitation.
Plant-Based is Different: True plant-based alternatives are fundamentally different, using no animal inputs whatsoever, and are the established vegan option.

Understanding Veganism: A Definition

To determine if lab-grown meat is vegan, one must first grasp the core tenets of veganism. Veganism is defined as a way of living that seeks to exclude, as far as is possible and practicable, all forms of exploitation of, and cruelty to, animals for food, clothing, or any other purpose. A vegan diet is strictly plant-based, excluding all animal products like meat, fish, eggs, dairy, and honey. This philosophy extends beyond diet, influencing lifestyle choices such as avoiding leather, fur, and products tested on animals. The crucial point is the exclusion of any product derived from an animal, regardless of whether that animal was killed to obtain it.

The Cultivation Process and Animal Inputs

Lab-grown meat, also known as cultivated or cellular meat, is produced by culturing animal cells in a controlled environment called a bioreactor. The process begins with a sample of animal cells, typically stem cells, which can be harvested through a biopsy from a living animal. While this initial biopsy can often be done painlessly, it still involves using an animal for human purposes, which many vegans consider a form of exploitation.

Historically, the most significant animal input was Fetal Bovine Serum (FBS), a growth medium derived from the blood of a calf fetus taken from a pregnant cow at slaughter. The use of FBS was a major point of contention within the vegan community and made the product unequivocally non-vegan. While many companies have developed or are actively developing animal-free alternatives, the industry's reliance on animal-derived cell lines at its foundation remains a sticking point.

Ethical Considerations Beyond Slaughter

For many, the appeal of cultivated meat lies in its potential to dramatically reduce the number of animals raised and slaughtered for food. It addresses a significant ethical problem by creating a product that is molecularly identical to conventional meat without mass-scale factory farming. This creates a nuanced discussion within the vegan community, with opinions varying widely.

The Pragmatic View: Some vegans and vegetarians might support the technology for its potential to reduce animal suffering on a global scale. By providing a product that can satisfy meat-eaters, it could steer a larger population away from supporting factory farming.
The Purist View: For many ethical vegans, however, the continued use of animal cells, even from a non-lethal biopsy, still constitutes animal exploitation. The existence of already available plant-based alternatives further strengthens the argument that cultivated meat is an unnecessary compromise.

Cultivated Meat vs. Plant-Based Alternatives

To clarify the distinction, a comparison table highlights the core differences between cultivated meat, plant-based alternatives, and traditional meat.


Feature	Lab-Grown (Cultivated) Meat	Plant-Based Meat	Traditional Meat
Starting Material	Animal stem cells	Plant proteins (e.g., soy, peas)	Animal muscle tissue
Origin	Laboratory/bioreactor	Food processing facility	Farm/livestock agriculture
Vegan Status	No (animal cells are used)	Yes (no animal inputs)	No (derived from slaughtered animals)
Animal Exploitation	Yes (requires initial cell biopsy)	No	Yes (requires slaughter and farming)
Environmental Impact	Potentially lower GHG emissions than traditional meat, depending on energy sources	Varies, generally lower than both	Significant GHG emissions, land, and water use

Addressing the Terminology

The ongoing debate often comes down to semantics. Is it still 'meat' if it's not from a slaughtered animal? Legally, this is still being defined, with some jurisdictions creating distinct labeling rules. Some proponents use terms like 'cultivated meat' to distance the product from traditional farming, while purists argue that any product containing animal cells should not be classified as vegan or even vegetarian.

What Does This Mean for the Future?

For the vegan movement, lab-grown meat presents both an opportunity and a challenge. It offers a path to reducing animal slaughter on a massive scale, which aligns with the core goal of reducing animal suffering. However, it requires a reevaluation of what constitutes 'animal exploitation' and whether 'animal-free' is the only acceptable standard. For consumers, the decision remains personal and ethical, with plant-based products offering a truly animal-free path, while cultivated meat provides an option that bypasses traditional animal agriculture for those who still desire the taste of meat.

One potential future development is the refinement of production processes to the point where no animal inputs are necessary whatsoever, including the initial cell biopsy. Researchers continue to explore induced pluripotent stem cells and animal-free growth mediums. However, until this becomes a commercial reality, is lab meat vegan? The answer, for now, remains no, based on the foundational principles of veganism.

Conclusion: Navigating the Nuance

While lab-grown meat is a revolutionary advancement that promises to reduce the horrors of factory farming, it does not currently fit the definition of veganism due to its reliance on animal cells, even if the animal was not harmed. The conversation around its ethical standing will continue, but the distinction is clear: vegan food is, by definition, 100% free of animal inputs from start to finish. Ultimately, consumers must decide if a slaughter-free product that still uses animal cells aligns with their personal ethics, but it is not a vegan option.

A note on the evolving landscape

As the cultivated meat industry advances, new innovations are being developed to create fully animal-free production methods, including initial cell collection and growth mediums. These theoretical advancements could one day shift the conversation, but until such products are commercially viable and widespread, the current reality persists. The future of cellular agriculture is dynamic, but for today's vegan, the plate remains filled with plant-based alternatives.

Frequently Asked Questions

Lab meat is not considered vegan because its production begins with a sample of animal cells, and even if the animal is not killed for this, it still involves using an animal for human purposes, which violates the core tenets of veganism.

No, lab meat is not vegetarian. The definition of vegetarianism excludes eating meat, and because cultivated meat is grown from actual animal cells, it is technically real meat, just produced differently.

While many companies are actively developing and transitioning to animal-free growth mediums to replace animal products like Fetal Bovine Serum (FBS), the initial cell line still originates from an animal source.

Lab-grown meat is real animal tissue grown from animal cells, while plant-based meat is a food product made to imitate meat using only plant-based proteins and other ingredients.

This is a subject of debate within the vegan community. While some might consider it, others would likely still refrain based on the foundational opposition to animal use, regardless of how far removed.

The debate exists because lab meat offers a solution to reduce slaughter but still relies on initial animal inputs. This forces a discussion on whether 'slaughter-free' is enough for some, or if '100% animal-free' is the only acceptable ethical standard.

Vegans can choose from a wide variety of plant-based products, including meat alternatives made from soy, peas, and other plant proteins, which are readily available and contain no animal inputs.
