There isn't one specific "best" vitamin for sun allergy, but several vitamins and supplements have been suggested to help lessen the symptoms. These include:
- Vitamin B3 (Niacinamide): Niacinamide can reduce the formation of kynurenic acid, a substance linked to photosensitivity.
- Beta-carotene: This antioxidant found in carrots and other orange fruits and vegetables may help protect the skin from sun damage.
- Selenium: This mineral may also help protect the skin from sun damage.
- Probiotics: Some dermatologists believe probiotics can help strengthen the skin's barrier function and reduce the severity of sun allergy symptoms.
- Vitamin D: Although it's produced in the skin with sun exposure, avoiding sun can lead to Vitamin D deficiency. Supplementing with Vitamin D might be beneficial after consulting a doctor.
It's important to note that while these vitamins and supplements may help with sun allergy symptoms, they are not a cure. The best way to prevent sun allergy is to avoid sun exposure during peak hours and to use sunscreen with an SPF of 30 or higher.
