Vitamin B2, known as riboflavin, is an easily absorbed micronutrient with a key role in maintaining health in humans and animals. Constructed of flavine, which is attached to a sugar alcohol, it is formed by the reduction of ribose called ribitol. And it is a water-soluble vitamin. Riboflavin is primarily absorbed in the proximal small intestine by a sodium dependent carrier. Within cells, vitamin B2 is converted to its coenzyme forms, regulated by hormones, such as the thyroid hormone. These coenzymes, than bind to apoenzymes forming what is called a flavoprotein. FMN and FAD (flavoproteins) are the principle forms of riboflavin. They are coenzymes, and used in several actions, particularly in the oxidation of agents, vital for many process to occur.

Like thiamin, vitamin acts as a coenzyme in the breakdown of fats, proteins, carbs, and other nutrients. It helps fatty acid reduction and choline catabolism. It also helps in releasing energy from carbohydrates. It is required for neurotransmitter (such as dopamine, and others) oxidation. It is necessary for catabolism of nutrients in the liver. Vitamin helps vitamin B6 in many reactions, as it is often FMN dependent. It also assists eye and skin maintenance. Above all, vitamin B2 is important for body growth, reproduction and red cell production.

Deficiency causes ariboflavinosis. These symptoms can include cracks in the lips, high aggrevation and sensitivity to sunlight, inflammation of the tongue, hyperemia, and swelling of the pharyngeal (throat). Extreme lack of riboflavin may slow the synthesis of the coenzyme form of vitamin B6 and niacin synthesis (later discussed within this article). Conditions and populations associated with increased need for riboflavin intake are many. Deficiency often occurs with heart disease, some cancers, thyroid disease, and excess alcohol intake.

We provide high quality vitamin B2. Recommended dosage is 0.2mg in 100g wheat, 0.9-095mg in 100g milk product. For soy sauce is 25-40mg/L. vitamin B2 should be stored in cool ventilated place. Keep away from light.
