Overview. Vitamin B2, also called riboflavin, is one of 8 B vitamins. All B vitamins help the body to convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body metabolize fats and protein.ataracts. Vitamin B2, along with other nutrients, is important for normal vision. Some early evidence shows that riboflavin might help prevent cataracts -- damage to the lens of the eye, which can lead to cloudy vision.
Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood.It is one of the eight B vitamins.It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism. Neither fungi, plants, nor animals (including humans) are capable of producing vitamin B 12.ecause intrinsic factor is crucial for the normal absorption of B 12, its lack in pernicious anemia causes a vitamin B12 deficiency. Many other subtler kinds of vitamin B 12 deficiency and their biochemical effects have since been elucidated.
