The health benefits of vitamin B2 according to its degree of effectiveness

Vitamin B2 provides a number of health benefits, which vary according to the degree of its effectiveness, and among these benefits, we mention the following:


Reducing the risk of vitamin B2 deficiency; It is possible to take vitamin B2 to increase its levels in the body in people who suffer from a decrease in it, and although the deficiency of this vitamin is rare, its occurrence may lead to the emergence of many severe skin problems, especially in the area around the mouth, tongue, and eyes.

Possibly Effective

  • Reducing elevated levels of homocysteine: A study published in the journal Circulation in 2006 indicated that consuming approximately 1.6 milligrams of vitamin B2 per day for 12 weeks may reduce the level of the amino acid homocysteine in the blood by up to 40% in some people who suffer from high blood pressure. The level of this acid, and a decrease in the levels of vitamin B2, and this rise occurs as a result of the body’s inability to convert homocysteine into the amino acid methionine, in addition to that, the consumption of this vitamin along with pyridoxine or what is known as vitamin B6, and folic acid may reduce the level of homocysteine by 100%. 26% of people suffer from a rise in it as a result of taking anti-epileptic drugs.

  • Reducing the risk of developing cataracts: Increasing the consumption of vitamin B2 as part of the diet, or by taking its nutritional supplements may be associated with reducing the risk of developing cataracts, and consuming supplements that contain vitamin B2 and vitamin B3 can contribute to reducing the risk of infection.

  • Reducing migraine attacks: One study was conducted on the effect of vitamin B2 on headaches, and this study, which was published in the Journal of Neurology, indicated that migraine headaches decreased by 50% when consuming 400 milligrams of vitamin B2 daily for a period of 3 months, and it was also noted that the number of The frequency of headache attacks has also decreased, to twice a month, and taking it with other types of vitamins and minerals can reduce the pain associated with migraines.

Possibly ineffective

  • Reducing the risk of kwashiorkor disease: which occurs due to malnutrition, specifically due to an acute deficiency in the level of protein in the body. A study from Washington University School of Medicine published in 2005 showed that taking vitamin B2 and selenium in addition to vitamin E and acetylcysteine for a period of 20 weeks. It does not reduce the risk of infection in children at risk of kwashiorkor, nor does it reduce fluid levels or increase weight and height.

  • Reducing the risk of lung cancer: Consuming vitamin B2 in addition to vitamin B3 does not help reduce the risk of lung cancer. Vitamins and minerals containing both vitamin B2 and vitamin B3 for about 5 years did not reduce the death rate from lung cancer.

  • Reducing the risk of malaria: Taking vitamin B2 in addition to vitamin B1, iron, and vitamin C does not reduce the severity of malaria infection or the number of times it occurs in children at risk of infection. On the other hand, a laboratory study from Northwestern University in Chicago in 2000 stated that vitamin B2 possesses anti-malarial activity properties, which can contribute to alleviating this infection caused by one of the primary parasites, which is called Plasmodium falciparum.

  • Reducing the risk of preeclampsia: This occurs due to high blood pressure during pregnancy, and it is possible to take vitamin B2 in the fourth month of pregnancy to reduce the risk of preeclampsia. A study from Women's College Hospital in 2000 stated that vitamin B2 deficiency is one of the factors associated with the risk of preeclampsia in 154 women, at a rate of 28.8%. The derivatives of this vitamin, or what is called flavin and adenine dinucleotides, decrease in women with preeclampsia compared to those without it. This leads to changes in the functions of the body’s organs and the emergence of some diseases, such as mitochondrial diseases, in addition to a high level of oxidative stress and others.

There is insufficient evidence of its effectiveness
