Vitamin B2, or riboflavin, performs a number of important functions in the body. It is necessary for the formation of red blood cells, antibody production, as well as cell respiration and growth. It also alleviates eye fatigue, and is important in the prevention and treatment of cataracts.
Riboflavin also aids the body with the metabolism of carbohydrates, fats, and proteins. It also works together with vitamin A to maintain and improve the mucous membranes in the digestive tract. It also facilitates the tissues of the skin, nails, and hair with the use of oxygen; eliminates dandruff, as well as helping the body to absorb iron and vitamin B6 (pyridoxine).
Vit B2 is also necessary for the metabolism of tryptophan, which is an amino acid which the body converts into niacin. Carpal tunnel syndrome often benefits from a treatment program which includes riboflavin and vitamin B6.
The symptoms of vit B2 deficiency can include cracks and sores at the corners of the mouth, eye disorders, inflammation of the mouth and tongue, and skin lesions. This group of symptoms all lumped together are often referred to as ariboflavinosis. Other possible deficiency symptoms include dermatitis, dizziness, hair loss, insomnia, sensitivity to light, poor digestion, retarded growth, and slowed mental responses.
The consumption of adequate amounts of riboflavin is especially important during pregnancy, as a lack of this vitamin can damage a developing fetus, even if a woman shows no signs of deficiency.
The foods which contain the highest levels of vit B2 include cheese, egg yolks, fish, legumes, meat, milk, poultry, spinach, whole grains, and yogurt. Other sources include asparagus, avocados, broccoli, Brussels sprouts, currants, dandelion greens, dulse, kelp, leafy green vegetables, mushrooms, molasses, nuts, and watercress.
Herbs which contain vit B2 include alfalfa, bladderwrack, burdock root, catnip, cayenne, chamomile, chickweed, eyebright, fennel seed, fenugreek, ginseng, hops, horsetail, mullein, nettle, oat straw, parsley, peppermint, raspberry leaves, red clover, rose hips, sage, and yellow dock.
The use of oral contraceptives and strenuous exercise increase the body's need for riboflavin. This B vitamin is easily destroyed by light, so foods and supplements containing vit B2 should be stored in a dark place. Antibiotics and the consumption of alcohol will also destroy this vitamin in the body. Taking too much riboflavin (more than 50mg daily) for a long period of time can lead to cataracts and retinal diseases.
