Deficiency symptoms In America severe deficiencies seldom occur except among the aged and individuals on diets lacking both amimai protein and green, leafy vegetables. Also, a deficiency in riboflavin usually indicates other B-complex vitamins may be lacking in the diet. Feeling tired without good reason is one of the rmiior symptoms. If fatigue accompanies or follows particularly stressful situations, you may be lacking riboflavin in addition to the other B vitamins. At times, a deficiency will cause your eyes to become sensitive to light, and they may also get bloodshot. Small cuts or wounds will not heal easily, and cracks may develop at the corners of the mouth if you are deficient in this vitamin.

Destroys vitamin or limits absorption Alcohol, estrogen, and sulfa drugs destroy riboflavin. Sodium bicarbonate used in cooking vegetables is destructive to riboflavin Because B2 is easily destroyed by light, milk should be kept in cartons and all supplements in dark bottles.

Toxicity None

Storage Over 50 percent of the riboflavin content of foods is lost when exposed to light for more than two hours. Those who lament days gone by when milk was delivered in clear glass bottles to the back doorstep should be aware that more than half the riboflavin content was lost as bottles stood outside basking in the early morning sunshine. Basically, however, this is one of the most stable vitamins, not affected by the fluctuating room temperatures found in most kitchens. So, cereals and other grain products can be stored safely in closed boxes on the kitchen shelves. As mentioned above, all vitamin supplements should be kept in dark bottles.

Processing effects Being one of the heat-stable vitamins, very little riboflavin is iost during the process of cooking unless sodium bicarbonate is added to maintain the green color of vegetables. Also, riboflavin is barely water-soluble, so little is lost in any process involving large amounts of water
