20 Vitamin B2 Foods Essential for Your Well-Being

Vitamin B2 Foods

Vitamin B2, also known as riboflavin, is one of eight B vitamins. When it comes to the history of vitamin B2, it was discovered by Blyth in 1879 and isolated by Kuhn, Gyorgy, and Wagner in 1933. Having numerous important functions, it is crucial for our health. It plays a major role in enzyme reactions that activate other vitamins, and it takes part in energy production, just like other B-complex vitamins. The infographic about vitamins prepared by our experts from MedAlertHelp.org will give you more information about this group of vitamins. Now we’ll see what vitamin B2 foods you should add to your eating plan to feel good and stay healthy.

What Is Vitamin B2?

Riboflavin is a water-soluble vitamin, meaning that it is carried through the bloodstream. The body doesn’t store this type of vitamin, but it excretes all excess amounts in urine. Therefore, you have to include foods rich in riboflavin in your everyday diet. Vitamin B2 is a component of two coenzymes (flavin mononucleotide and flavin adenine dinucleotide) which have essential roles in the metabolism of fats, drugs, and steroids. They also play an important part in energy production in the body.

Vitamin B2 Benefits

Along with vitamin B1, riboflavin takes part in the metabolic process of breaking down carbohydrates, proteins, and fats, and the production of ATP (adenosine triphosphate). ATP is the body’s energy source for all vital processes. Another vitamin B2 function is to contribute to the production of red blood cells. Stimulating antibody production, it also helps in strengthening the immune system.

Thanks to riboflavin, the body is able to absorb and activate iron, folic acid, and vitamins B1, B3, and B6. Vitamin B2 enables adrenal glands to produce hormones. Along with vitamin A, it maintains a healthy liver, skin, and hair. Normal fetal development depends on this vitamin as well. According to some studies on vitamin B2, migraine may be prevented with high-dose riboflavin treatment.

Sources of Vitamin B2

Riboflavin can be found in various foods, but meats, eggs, and dairy products are especially high in this nutrient. Vitamin B2 is also often added to certain types of food, like grains and cereals. It’s good to know that a lot of riboflavin content is lost when you boil food because vitamin B2 is soluble in water. Therefore, it’s better to prepare it in a different way, for example, by grilling or steaming.

Since a balanced diet can prevent vitamin B2 deficiency diseases, here you can find a list of healthy foods that you should include in your eating plan.

Beef

Beef, like all meats, is a great source of riboflavin. Three ounces of grilled tenderloin steak will provide you with 24% of your daily value (DV) of vitamin B. However, beef liver is even a better option as three ounces of pan-fried liver serve 171% of your DV of riboflavin.

Recommended Daily Intake

The Food and Nutrition Board (FNB) at the Institute of Medicine of the National Academies developed the Dietary Reference Intakes where you can find intake recommendations for all the important nutrients. Here we will provide you with the values of the recommended dietary allowances (RDA) for riboflavin. RDA represents an average daily intake that is meant to meet the nutrient requirements of healthy people. If your riboflavin intake is too low, you are at risk of developing vitamin B2 deficiency. Therefore, it’s important to adopt healthy eating habits and include a variety of foods in your diet.

The recommended dietary allowances of vitamin B2 depending on age and sex are the following:

  • From birth to 6 months – 0.3 mg
  • From 7 to 12 months – 0.4 mg
  • From 1 to 3 years – 0.5 mg
  • From 4 to 8 years – 0.6 mg
  • From 9 to 13 years – 0.9 mg
  • From 14 to 18 years – 1.3 mg (male) and 1.0 mg (female)
  • 19+ years – 1.3 mg (male) and 1.1 mg (female)

However, women should increase their daily intake of riboflavin during pregnancy and lactation. The RDAs for vitamin B2 during pregnancy and lactation are 1.4 mg and 1.6 mg, respectively.

Vitamin B2 Deficiency Symptoms

A healthy eating plan is very important as a poor diet can lead to nutrient deficiencies, including a riboflavin deficiency. Since the body isn’t able to store water-soluble vitamins, the inadequate intake of vitamin B2 can result in ariboflavinosis, which is another name for low levels of vitamin B2. This type of deficiency caused by poor diet is called primary and can easily be prevented by eating sufficient amounts of foods with vitamin B2. Secondary deficiency can be a consequence of the body’s inability to absorb riboflavin properly. It can also be caused by endocrine abnormalities or some diseases.

There are a number of symptoms of riboflavin deficiency, including skin disorders, such as dry skin, redness, and swelling of the mouth and throat. Other signs of deficiency are lesions at the corners of the mouth, swollen, cracked lips, and hair loss. It can also cause inflammation of the tongue, sore throat, and itchy and red eyes. Some of the more serious problems related to this health condition are reproductive problems and degeneration of the liver and nervous system. Low levels of vitamin B2 may have adverse effects on the metabolism of other nutrients as well. Severe riboflavin deficiency may even lead to anemia and cataracts.

Who Should Take Vitamin B2 Supplements?

A diet including a variety of healthy foods is the key to our health and the best way of preventing nutrient deficiencies. However, vitamin supplements can be used as a part of a vitamin B2 deficiency treatment. Although riboflavin deficiency is pretty rare, there are a few groups that are at greater risk of developing this condition.

First, athletes who follow a vegetarian diet are more likely to have lower levels of riboflavin. Due to their increased physical activity, they need a higher amount of vitamin B2. On the other hand, if they avoid eating all animal products including dairy products and eggs, they are excluding really good sources of this vitamin, which can result in a riboflavin deficiency.

Secondly, pregnant women or women who are breastfeeding are likely to become deficient in vitamin B2 if they don’t consume enough meat or dairy products. This can negatively affect both mothers and their infants.

Furthermore, people with the Brown-Vialetto-Van Laere syndrome need vitamin B2 supplementation as this disease causes riboflavin deficiency.

Vitamin B2 Side Effects

Since riboflavin is a water-soluble vitamin, the body excretes all the excess amounts of it, and therefore there is no risk of overdosing with vitamin B2. Still, you should always be careful with nutrient supplementation. Never take it if you haven’t consulted with your physician as riboflavin supplements can interact with some medications.

Conclusion

Vitamin B2 or riboflavin has a crucial role in energy creation and nutrient absorption. Since a number of processes depend on this nutrient, it is essential for enabling our body to function normally. A poor diet can result in riboflavin deficiency, which can further lead to some serious health conditions. That’s why it’s of tremendous importance to include foods rich in riboflavin in your eating plan.
