25 Vitamin B2 Foods Essential for Your Well-Being

Vitamin B2 Foods

Vitamin B2, also known as riboflavin, is one of eight B vitamins. Notably, it plays a significant role in enzyme reactions that activate other vitamins, and it takes part in energy production, just like other B-complex vitamins.

The guide below will give you more information about the nutrient, along with the list of the most critical vitamin B2 foods. In other words, you’ll get to discover what you should introduce to your diet to feel good and stay healthy.

What Is Vitamin B2?

Riboflavin is a water-soluble vitamin carried through the bloodstream. To put it differently, the body doesn’t store this type of vitamin, excreting all excess amounts in urine. Following that, you have to include foods high in riboflavin in your everyday diet.

Generally speaking, vitamin B2 is a component of two coenzymes (flavin mononucleotide and flavin adenine dinucleotide). The two coenzymes 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 thiamine (vitamin B1), riboflavin breaks down carbohydrates, proteins, and fats. It also partakes in the production of ATP (adenosine triphosphate). ATP is the body’s energy source for all vital processes. Another riboflavin function is contributing to the production of red blood cells. By stimulating antibody production, the vitamin helps strengthen the immune system.

Riboflavin benefits also include the absorption and activation of folic acid, iron, vitamin B1, vitamin B3, and vitamin B6. Another perk is that vitamin B2 enables adrenal glands to produce hormones. Also, with the help of vitamin A, it helps maintain a healthy liver, skin, and hair.

According to some studies on vitamin B2, migraine can be prevented with high-dose riboflavin treatment. Normal fetal development depends on this vitamin as well.

Riboflavin Foods

Riboflavin can be found in various foods, but meats, eggs, and dairy products are exceptionally high in this nutrient. Vitamin B2 is also often added to certain types of food, like grains and cereals.

Sadly, a lot of riboflavin content is lost when you boil food because vitamin B2 is soluble in water. Therefore, it’s better to prepare foods with the nutrient differently, for example, by grilling or steaming.

Below you can find a list of healthy foods that you should include in your diet to prevent vitamin B2 deficiency diseases and enhance your overall well-being. Let’s dive right in.

Vitamin B2 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 crucial nutrients. Here we will provide you with the values of the recommended dietary allowances (RDA) for riboflavin.

This 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 various foods in your diet.

Vitamin B2 recommended daily intake depends on age and sex and is 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)

Keep in mind that women should increase their vitamin B2 dose 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 critical as a poor diet can lead to nutrient deficiencies. Since the body cannot 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 a 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. Endocrine abnormalities or some diseases can also cause it.

There are several B2 vitamin deficiency symptoms. Some of them include skin disorders, such as dry skin, redness, and swelling of the mouth and throat. Other riboflavin deficiency symptoms and signs 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 severe problems related to this health condition are reproductive problems and degeneration of the liver and nervous system. B2 vitamin deficiency may have adverse effects on the metabolism of other nutrients as well. Severe lack of this vitamin 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. That said, vitamin supplements can be used as a part of a vitamin B2 deficiency treatment. Although this deficiency is pretty rare, a few groups 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. All in all, if they avoid eating all animal products, including dairy products and eggs, and other vitamin B2 foods, vegetarians exclude really good sources of this vitamin, which can result in a B2 deficiency.

Secondly, pregnant women or women who are breastfeeding are likely to become deficient in vitamin B2 if they don’t find enough riboflavin in food (if they don’t eat 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 B2 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 little to no risk of overdosing with vitamin B2. Note that you should consult a healthcare professional about nutrient supplementation first, as riboflavin tablets might interact with some medications.

Conclusion

Vitamin B2, or riboflavin, has a crucial role in energy creation and nutrient absorption. Since several 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 severe health conditions. That’s why it’s of tremendous importance to include foods rich in riboflavin in your diet.
