FAQ
Frequently Asked Questions
Yes, 'riboflavin' is the scientific name for vitamin B2. They are synonymous.
Excellent sources include dairy products (milk, yogurt), eggs, lean meats, organ meats (liver), green leafy vegetables, and fortified cereals and breads.
Deficiency (ariboflavinosis) can lead to sore throat, redness and swelling of the lining of the mouth and throat, cracks or sores on the lips (cheilosis) and at the corners of the mouth (angular stomatitis), a swollen, magenta-coloured tongue (glossitis), skin disorders, and anaemia.
Riboflavin is water-soluble, so excess amounts are excreted in urine, making toxicity very rare. High doses may cause bright yellow discolouration of urine, which is harmless.
