Sources:

Riboflavin is found in foods such as eggs, lean meats, dairy products, green leafy vegetables, nuts, and enriched cereals and grains. It is also available in supplement form, often as part of B-complex vitamins.

Cellular Growth: Riboflavin is crucial for growth, development, and the maintenance of healthy skin and eyes.

Riboflavin deficiency, known as ariboflavinosis, can cause symptoms such as sore throat, redness and swelling of the lining of the mouth and throat, cracks or sores on the outsides of the lips, and inflammation of the tongue.
