Riboflaviini

Riboflaviini, also known as vitamin B2, is an essential nutrient found in many foods. It is a water-soluble vitamin that plays a crucial role in energy metabolism, cell growth, and the breakdown of fats, drugs, and steroids. Riboflaviini is a precursor to the coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), which are vital for various enzymatic reactions in the body.

Sources of riboflaviini include dairy products, eggs, lean meats, green leafy vegetables, legumes, and fortified cereals. Deficiency in riboflaviini is uncommon in developed countries but can occur in individuals with poor dietary habits, alcoholism, or certain medical conditions that affect nutrient absorption. Symptoms of riboflaviini deficiency, known as ariboflavinosis, can include cracks and sores in the corners of the mouth (cheilosis), inflammation of the tongue (glossitis), skin rashes, and eye problems such as light sensitivity and blurred vision.

Riboflaviini is important for maintaining healthy skin, eyes, and nerve function. It also acts as an antioxidant, protecting cells from damage caused by free radicals. The body does not store large amounts of riboflaviini, so a regular intake through diet is necessary. It is often included in multivitamin supplements. High doses of riboflaviini are generally considered safe, as excess amounts are excreted in the urine, which can turn a bright yellow color.
