                                According to scientific studies, the synthetic form of vitamin B9, folic acid, undergoes rapid photodegradation when exposed to ultraviolet (UV) light. This light sensitivity can significantly impact the stability and effectiveness of your folic acid supplements and fortified foods over time.
