Which foods contain Vitamin B2?

Many green leafy vegetables and beans also contain a lot of vitamin B2, while cereals and general vegetables contain less.

What is Vitamiin B2 Benefits ?
Helps maintain eye health
Research shows that its deficiency increases the risk of certain eye problems, including glaucoma, cataracts, keratoconus, and more. There is a correlation between people who consume adequate amounts and a reduced risk of eye problems that occur as they age.
2) Can help prevent and treat anemia
Anemia is caused by a variety of factors, including decreased red blood cell production, an inability to deliver oxygen to the blood, and blood loss. Vitamin B2 is required for steroid hormone synthesis and red blood cell production, and it also helps deliver oxygen to cells and helps mobilize iron.
3) Needed to maintain proper energy levels
It is considered an important component of mitochondrial energy. It is used by the body to metabolize food for energy and to maintain proper brain, nerve, digestive, and hormone function. This is why it is so important for growth and body repair. Without high enough levels of riboflavin, molecules from carbohydrate, fat, and protein foods cannot be properly digested and used as "fuel" to keep the body running.
4) Antioxidant properties
As an antioxidant, it controls the presence of harmful free radicals in the body. It is required for the production of an antioxidant called glutathione, which is a free radical killer and also detoxifies the liver.
5) Protects Healthy Hair and Skin
Vitamin B2 Riboflavin plays a role in maintaining collagen levels, which make up healthy skin and hair. A lack of riboflavin can make us look older faster. Some studies have shown that it can reduce the time it takes for wounds to heal, reduce skin inflammation and chapped lips, and help naturally slow down the signs of aging.
