Is Beta-Carotene (E160a) Vegan?

Also known as: Provitamin A, Natural orange color

Depends on Source

Last checked 29 Jul 2026 How we decide

Beta-carotene depends on the formulation, not the pigment. Every commercial route to the color is animal-free: carrots and algae, fermentation by the fungus Blakeslea trispora, or chemical synthesis. The catch is the beadlet holding it, commonly gelatin, so ask a supplement maker which carrier they use.

Which animal, and does it die

Comes from: pig, cattle, or fish, via the gelatin used as a beadlet carrier or capsule shell
Requires slaughter: Yes

Vegetarian depends on the source

From a mammalRelevant to alpha-gal syndrome
Pig is a common sourceRelevant to halal and kosher diets
Fish-derivedRelevant to a fish allergy

These flags describe sourcing. They are not an allergen assessment, and a vegan label is not a free-from claim. If you have an allergy, read the allergen declaration on the pack.

E-Number

E160a

Also Known As

Provitamin A; Natural orange color

Source

Produced from three routes, all of them free of animal material: extraction from plants and algae (carrots, palm fruit, Dunaliella salina), fermentation by the fungus Blakeslea trispora, and chemical synthesis. The vegan question sits in the formulation rather than the pigment. Beta-carotene is fat-soluble and unstable, so it is commonly sold as beadlets stabilised in a carrier, and gelatin is a common carrier. The color is plant-derived; the capsule around it may not be.

Commonly Found In

Margarine, butter substitutes, cheese, juices, soups. Also in supplements as a Vitamin A precursor.

Vegan Alternative

Beta-carotene itself needs no substitute. Ask the manufacturer whether the beadlet carrier is gelatin or a plant gum such as acacia or modified starch.

Additional Notes

In most food products, E160a is synthetic or algae-derived and is vegan. In supplements the pigment is still plant or microbial; what needs checking is the carrier it is suspended in and the capsule holding it, both of which are commonly gelatin.

In depth

How Beta-Carotene Is Produced

Commercial beta-carotene reaches the food supply through three main routes. A large share is manufactured synthetically. Chemical steps build up a molecule identical to the one found in plants. A second route is extraction from natural sources such as carrots, palm fruit, or the microalga Dunaliella salina, which accumulates high concentrations of the pigment. A third route uses fermentation, in which cultured microorganisms such as the fungus Blakeslea trispora produce the compound, after which it is isolated and purified.

All three routes are free of animal inputs. Beta-carotene is sometimes formulated together with fish-derived vitamin A in high-dose preparations, which makes the finished supplement animal-derived while leaving the beta-carotene itself plant or microbial. For everyday food coloring, synthetic and plant- or microbe-derived beta-carotene dominate the market, which is why E160a in packaged food is generally considered vegan.

Reading Labels and Regional Naming

In the European Union and countries following EU conventions, beta-carotene appears on ingredient lists as its E number, E160a, sometimes written as "carotenes" or "mixed carotenes." The United States does not use E numbers. There the same additive is listed by name, often as "beta carotene," "beta-carotene (color)," or under a general "artificial color" or "color added" statement.

The label rarely states which production route was used, so the E number alone does not reveal whether the source was synthetic, algal, or fermentation-based. For food products the uncertainty rarely matters. Animal-derived beta-carotene is not standard in the food-grade supply. The exception is dietary supplements, especially concentrated Vitamin A products, where the source is more variable and worth confirming with the manufacturer if it matters to you.

Where People Are Surprised to Find It

Beta-carotene is added far beyond obvious orange foods. It commonly provides the yellow tint in margarine and plant-based butter substitutes, giving them a butter-like appearance. The same colorant goes into some cheeses and cheese-style products, processed juices, soft drinks, soups, sauces, baked goods, and confectionery.

Because the pigment is also a Vitamin A precursor, it turns up in fortified foods and in multivitamins and standalone supplements, where it doubles as both a colorant and a nutrient. Its presence in a bright-orange product like carrot juice is expected, but its use in pale items such as crackers, dressings, and dairy alternatives can be less intuitive. In all of these food applications, the beta-carotene used is typically synthetic or plant- or microbe-derived and therefore suitable for a vegan diet.

Vegan Status and Verifying Supplements

For the large majority of foods, beta-carotene labeled as E160a can be treated as vegan, because the colorant used in food manufacturing is synthetic or sourced from carrots, palm, algae, or fermentation. No animal slaughter or animal secretion is involved in these standard routes.

The practical exception is supplements. High-dose vitamin A formulations often pair beta-carotene with retinol from fish liver oil, and the beadlet carrier and softgel shell are both commonly gelatin. If you follow a strictly vegan diet, the reliable approach is to check for an explicit vegan or plant-derived claim on the supplement, look at the capsule material, or contact the manufacturer directly. Products carrying a recognized vegan certification remove most of this ambiguity.

Frequently asked questions

Is beta-carotene vegan?

In most cases, yes. The beta-carotene used as a food color (E160a) is typically synthetic or derived from plants, algae, or fermentation, none of which involve animal ingredients. The main exception is some supplements, where the source and the capsule material should be verified.

Is E160a the same as beta-carotene?

Yes. E160a is the European additive code for beta-carotene and mixed carotenes. In the United States the same ingredient is listed by name, so "beta carotene" on a US label and "E160a" on an EU label refer to the same colorant.

Why is beta-carotene sometimes not vegan?

The concern is limited mainly to supplements. High-dose vitamin A preparations often combine it with fish-derived retinol, the beadlet carrier is frequently gelatin, and softgel shells usually are too. Food-grade beta-carotene used as a colorant does not normally rely on animal sources.

Is the beta-carotene in margarine vegan?

Generally yes. Beta-carotene is added to margarine and plant-based butter substitutes to give a yellow, butter-like color, and the food-grade colorant used is synthetic or plant- or microbe-derived. Any animal-based ingredients in a margarine would come from other components, such as milk derivatives.

How can I tell if a beta-carotene supplement is vegan?

Look for an explicit vegan or plant-derived statement on the label, since the source is not always printed. Check the capsule material as well. Softgels can contain gelatin. When it is not clear, contacting the manufacturer or choosing a product with a recognized vegan certification is the most reliable approach.
