Canthaxanthin

How does Canthaxanthin work?

Canthaxanthin is a dye similar to the carotenes in vegetables such as carrots. It deposits in the skin to produce an artificial "tan." It might protect against sun sensitivity through antioxidant activity.

Are there safety concerns?

Canthaxanthin is LIKELY SAFE when taken by mouth in food amounts. However, it is LIKELY UNSAFE when taken by mouth in amounts needed for artificial tanning. Some people who have taken canthaxanthin for these purposes have experienced eye damage and vision loss.

At high doses, canthaxanthin has caused a serious, potentially fatal blood disorder called aplastic anemia. Canthaxanthin can also cause diarrhea, nausea, stomach cramps, dry and itchy skin, hives, orange or red body secretions, and other side effects.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Canthaxanthin is POSSIBLY UNSAFE for pregnant or breast-feeding women when taken by mouth in medicinal amounts to reduce sun sensitivity. It's LIKELY UNSAFE when taken by mouth in amounts needed to produce a tan. It can cause eye damage and other harmful effects.

Vitamin A allergy: People who are allergic to vitamin A and related chemicals called carotenoids might also be sensitive to canthaxanthin.

Dosing considerations for Canthaxanthin.

The following doses have been studied in scientific research:

BY MOUTH:
  • For reducing and treating rash, itch, and/or eczema (symptoms of photosensitivity) in people with erythropoietic protoporphyria (EPP) when they are exposed to sunlight: 60 to 90 mg of canthaxanthin daily on average for three to five months per year.
