Vaginal dryness can take vitamin b2. Vaginal dryness is often caused by gynecological inflammation or psychological reasons, as well as b2 deficiency and endocrine disorders. Taking vitamin b2 supplements can balance the nutrients in the body and relieve vaginal dryness. It is suggested to eat more foods rich in vitamin b2, such as milk and its flower-making and lamb-wearing products, animal liver and kidney, egg yolk, eel, carrot and mushroom.
