The Benefits of Vitamin B2 (Riboflavin) and Where to Get It

Published by Wonder Laboratories on Mar 22nd 2018

If you're feeling low on energy these days (and maybe that's the last thing you need with spring starting to sprout), then it could be your tank is running low on vitamin B2 (also known as riboflavin). Our bodies need a daily intake of vitamin B2, a water-soluble vitamin that has a significant role in energy production and is an essential nutrient in our diets. Riboflavin (a term we will use in place of vitamin B throughout for the sake of variety) is one of eight B-complex vitamins that for some health purposes depend on one another – sort of like a family that plays together sticks together? Essentially, what vitamin B2 does, per, is break down carbohydrates, proteins, and fats to generate energy, while also allowing oxygen to be used by the body.

Vitamin B2 Deficiency

Cases of vitamin B2 deficiency are rare in the U.S. and other developed countries, which is understandable because most Americans and other Westerners do well in keeping themselves fed – and B2 does have many food sources. There are a number of signs or symptoms that could indicate such a shortage in our bodies. Deficiency indications can include anemia, sore throat, mouth or lip sores, inflammation of the skin and the swelling of soft tissue in the mouth, per OK, so each of those symptoms, on their own, might suggest some other condition. So, below are a few more symptoms of a lack of vitamin B2, which might help narrow down the cause should you be so afflicted. By the way, such a deficiency can be caused by factors other than a lack of consumption, such as endocrine abnormalities and other diseases, per National Institutes of Health (NIH):
  • Fatigue.
  • Bloodshot eyes.
  • Increased sensitivity to light.
  • Burning sensation in the eyes.
  • Nerve damage.
  • Sluggish metabolism.
  • Swelling of mucus membranes.
  • Mood changes, to include heightened anxiety or signs of depression.

Vitamin B2 Makeup

Most forms of dietary riboflavin – 90 percent of them, in fact, per NIH – are either riboflavin-5'-phosphate (FMN) or flavin adenine dinucleotide (FAD). Both are coenzymes that play significant roles in energy production; cellular function, growth, and development; and the metabolism of fats, drugs, and steroids. Once ingested – and note that more riboflavin is produced with the consumption of a vegetable-based food vs. a meat-based food – small amounts of riboflavin are stored in the liver, heart, and kidneys, while the rest is either not absorbed or is excreted through the passing of urine. Either way, B2 doesn't stick around in our bodies for a long time.

Vitamin B2's Health Benefits

With that, let's move beyond the talk of deficiencies and how riboflavin is ingested, and go straight to the benefits that B2 offers us. Read 'em and rejoice:
  • Energy booster. Riboflavin's role in metabolizing fats, carbohydrates, and proteins is what helps in generating energy, per
  • Improve blood circulation. B2 is key to this by its involvement in the production of fresh red blood cells and antibodies – both of which enhance circulation and oxygenation to various body organs.
  • Promote growth and development. This applies to the reproductive organs, body tissues, and the immune system. Think healthy skin, nails, and hair.
  • Repair tissue. B2 also is involved in the healing of wounds and various injuries that typically take a long time to heal.
  • Eye health. For one thing, riboflavin helps protect glutathione, a key antioxidant in the eye, per the University of Michigan. Also, per the U.S. National Library of Medicine, a riboflavin-rich diet can reduce the risk of developing cataracts.
  • Skin care. B2 accomplishes this by promoting the skin's secretions of mucus and by cleaning up skin pustules associated with acne.
  • Bolster absorption of minerals. To include iron, folic acid, and other B vitamins.
  • Protect digestive tract. Does this mainly by helping to take good care of the mucus membranes.
  • Other benefits include healthy fetal development, enhancing the immune system, and guarding the nervous system.

You don't have to search everywhere to find natural sources of vitamin B2 – in addition, of course, to dietary supplements readily available in the marketplace. Here are some of the best food sources of B2:
  • Dairy products.
  • Seaweed.
