V i t a m i n B 2
Vitamin B2 (Riboflavin) is required for a wide variety of cellular processes, important for body growth and the production of red blood cells.
It functions primarily as a coenzyme for many metabolic processes. Like all B vitamins, riboflavin is necessary in order to convert carbohydrates from food into glucose. Additionally, riboflavin helps the body metabolize proteins and fats.
Vitamin B2, along with iron, is required for the production of red blood cells, which are responsible for the transport of oxygen throughout the body.
Moreover, it boosts the functioning of the nervous system. It strengthens the mucous lining of the mouth, tongue and lips and is also responsible for healthy skin, nails and hair. Finally, it plays a vital role in the prevention of glaucoma. While vitamin A is responsible for good vision, vitamin B2 strengthens the nerves and muscles of the eyes.
Riboflavin is essential to the body for a wide range of functions. It has a profound effect on the thyroid hormone production, which is responsible for speeding up the metabolism and providing steady energy.
It helps the body produce immune cells to fight infection, and along with iron, helps build red blood cells to transport oxygen to body cells. Riboflavin also converts niacin and B-6 into active forms so the body can use them effectively. It assists other nutrients as powerful antioxidants.
Vitamin B2 is generally stable during heat processing and normal cooking of foods, if light is excluded.
Vitamin B2 helps to promote and maintain healthy skin. Riboflavin acts to to improve the secretion of mucus in the skin. It is used to prevent and treat skin problems such as dermatitis, eczema and rosacea.
In tests it was shown, that 100 mg Riboflavin per day reduces the vulnerability for migraine at about 50%. One of the more unique functions of riboflavin is that it combats some of the effects of aging, particularly memory loss and also preventing the development of cataracts.
