Yes, vitamins can degrade when exposed to sunlight.
Sunlight's Impact on Vitamins
Sunlight, specifically ultraviolet (UV) radiation, can accelerate the degradation of many vitamins. This is because UV light can break down the chemical structures of these sensitive nutrients, rendering them less effective or even completely inactive. This process is known as photodegradation.
To ensure the maximum shelf life of your vitamin supplements, it is best to store them in their original containers and in a cool, dry place out of direct sunlight. Storing them in areas like the kitchen or bathroom, which tend to be warmer and more humid, should be avoided because heat and moisture can also negatively affect supplement quality.
Types of Vitamins Affected
While many vitamins are susceptible to sunlight damage, some are more sensitive than others. Vitamins like Vitamin C and Vitamin B12 are particularly vulnerable to photodegradation. The extent of degradation depends on several factors, including the intensity and duration of sun exposure, as well as the specific formulation of the vitamin.
Practical Tips for Vitamin Storage
- Keep vitamins in their original containers: These containers are designed to protect the contents from light, air, and moisture.
- Store in a cool, dark place: A cupboard or drawer away from sunlight and heat sources is ideal.
- Check expiration dates: Even when stored properly, vitamins have a limited shelf life. Always check the expiration date before using them.
- Avoid storing in bathrooms or kitchens: These locations tend to be humid and warmer, increasing the chance of degradation.
