B2 (Riboflavin)
Riboflavin is water-soluble. It is stable to heat,
oxidation and acid. It disintegrates in the presence of alkali or UV light.
Riboflavin is necessary for cell respiration because it works with enzymes in
the utilization of cell oxygen. It functions as part of a group of enzymes that
are involved in the breakdown and utilization of carbohydrates, fats and
proteins.
There is no known toxicity of riboflavin. An early sign
of deficiency is the appearance of cracks and sores in the corners of the
mouth, a red, sore tongue, a feeling of grit and sand on the insides of the
eyelids, burning of the eyes, changes in the cornea, sensitivity to light,
lesions of the lips, scaling around the nose, mouth, forehead and ears,
trembling, sluggishness, dizziness and a lack of stamina.
