A. Mouth sores
Vitamin B2, also called riboflavin, is one of 8 B vitamins. Signs of deficiency include cracks and sores at the corner of the mouth; fatigue; digestive problems; swollen, magenta-colored tongue; itchy and burning eyes; and sensitivity to light. B2 deficiency has been linked to cataracts and migraine headaches. All B vitamins help the body to convert food (carbohydrates) into glucose) used to produce energy. They also help the nervous system function properly. The B vitamins, often referred to as B-complex vitamins, also help the body metabolize fats and proteins. B vitamins are water soluble, so the body does not store them. Bruising is a sign of Vitamin C deficiency (scurvy). Night blindness indicates Vitamin A deficiency. Muscle cramps, aches, or weakness indicate a Vitamin D deficiency.
B. Night blindness
C. Muscle cramps
D. Frequent bruising
