Safety in brief
Safe
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.

- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Canthaxanthin is a carotenoid pigment, occurring naturally in some mushrooms, crustaceans, and fish, and also produced synthetically for use as a food and animal-feed additive (E161g). In food, it has been used to enhance the color of items like sausages, and in animal feed it intensifies pigmentation of egg yolks, poultry skin, and farmed salmon. Regulatory agencies including EFSA and FDA have set strict intake limits following documented cases of canthaxanthin retinopathy — a reversible condition involving crystalline deposits in the retina — linked to high-dose use (historically including its use as a tanning-pill ingredient, now banned for that purpose).

Research & body effects
Health notes from our ingredient record
- Linked to canthaxanthin retinopathy at high intakes, a generally reversible condition involving crystal deposits in the retina.
- EFSA has significantly lowered the Acceptable Daily Intake for canthaxanthin due to these eye-safety findings; food-additive use is now more restricted than in the past.
- Excessive intake can also cause harmless skin discoloration (carotenodermia).

Country checks for E161G
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.
EU food-use restriction: Canthaxanthin is not authorised in the food categories listed in Parts D and E. The entry is retained because of its use in medicinal products; that is not a food-use permission. Read the dated EU list and footnote.
