Ariboflavinosis is a result of a deficiency in which of the following nutrients?

Ariboflavinosis is indeed a consequence of a deficiency in riboflavin, which is also known as vitamin B2. This nutrient plays essential roles in the body, particularly in energy production and the metabolism of fats, drugs, and steroids. Riboflavin is a water-soluble vitamin that is crucial for the normal functioning of various enzymes, particularly those involved in oxidative reactions.

A deficiency in riboflavin can lead to symptoms such as sore throat, redness and swelling of the lining of the throat, cracks and sores on the outsides of the lips (cheilosis), and at the corners of the mouth (angular stomatitis), along with inflammation of the tongue (glossitis). These symptoms collectively characterize ariboflavinosis.

In contrast, folate, vitamin B-12, and vitamin C serve different vital functions in the body. Folate is primarily involved in DNA synthesis and repair, vitamin B-12 is essential for nerve function and the production of red blood cells, and vitamin C is key for collagen synthesis and acts as an antioxidant. Each of these vitamins has its own deficiency-related conditions, but they do not cause ariboflavinosis. Thus, riboflavin is
