Vitamin B2, also known as riboflavin, plays an important role in maintaining human health. It is one of the key elements involved in cellular respiration and energy metabolism processes.
Vitamin B2 is necessary for converting food into energy, supporting the functions of the nervous system, and ensuring the health of the skin, eyes, and hair. It is also vital for the development and functioning of many enzyme systems, as well as protecting the body from oxidative stress.
Research shows that riboflavin may influence energy levels and overall well-being, which in turn can affect mood.
Riboflavin supports the immune functions of the body by participating in processes necessary for protection against infections.
Maintaining adequate levels of riboflavin is critical for overall well-being. It needs to be consumed regularly, as the body cannot store this water-soluble vitamin in large amounts.
Riboflavin is involved in the restoration and activation of other vitamins, particularly folic acid and vitamin B6. Without sufficient amounts of vitamin B2, these and other vital processes may be disrupted, highlighting its significance in maintaining overall health.
Daily Requirement for Vitamin B2
The daily requirement for vitamin B2 depends on age, sex, and health status. On average, adult men are recommended to receive about 1.3 mg of vitamin B2 per day, while adult women need about 1.1 mg. For pregnant and breastfeeding women, the requirement increases to about 1.4 mg and 1.6 mg respectively.
Signs and Consequences of Vitamin B2 Deficiency
A deficiency of vitamin B2 can lead to a number of diseases and symptoms, as it plays an important role in cellular respiration processes.
The main signs of vitamin B2 deficiency include corners of the mouth that may become inflamed, painful, and cracked – a condition known as cheilosis or angular stomatitis.
Skin changes may also occur, especially in the area of the nose and forehead, manifesting as peeling and dermatitis. There may be a decline in vision, especially in dim light, which is a sign of what is known as “night blindness.”
Additionally, changes in the mucous membranes of the mouth and eyes may lead to dryness, burning, itching, and light sensitivity.
With prolonged riboflavin deficiency, anemia may develop, as well as neurological symptoms such as fatigue, headaches, and even depression.
Due to the important role of vitamin B2 in metabolism, its deficiency can negatively affect the body’s energy balance.
Potential Risks and Complications from Excess Vitamin B2
Studies show that even with the consumption of vitamin B2 in amounts significantly exceeding the recommended daily doses, serious complications are not observed.
However, some individuals may experience minor side effects, such as yellow urine (due to the excretion of excess riboflavin), diarrhea, or increased urination.
Allergic reactions to high doses of vitamin B2 are extremely rare but possible.
Sources of Vitamin B2 in the Diet
Vitamin B2, also known as riboflavin, is an important vitamin that plays a key role in energy metabolism and maintaining normal vision and skin health. The recommended daily amount of riboflavin can be obtained by including certain foods in the diet.
Animal sources: Important sources of vitamin B2 are animal products.
Dairy products, such as milk and yogurt, are rich in riboflavin.
Significant amounts of the vitamin are also found in eggs, liver, and meat, especially beef and pork.
Plant sources: Good sources of vitamin B2 include green leafy vegetables such as spinach, broccoli, and asparagus. Additionally, nuts and seeds, such as almonds and sunflower seeds, also contain this vitamin.
When composing a balanced diet, it is important to consider that vitamin B2 is sensitive to light and may break down with prolonged exposure to sunlight. Therefore, it is recommended to store foods rich in riboflavin in dark or opaque containers.
