What is Riboflavin?

Also known as vitamin B2, riboflavin is one of eight essential vitamins that your body needs to metabolize protein and fat and to convert carbohydrates into glucose, which your body uses for energy.

Riboflavin is needed for your brain functions and nervous system. It also supports the health of your liver, eyes, skin, and hair. Riboflavin is a water-soluble vitamin and as such is not stored in your body. For this reason, you need to obtain a regular supply from your daily diet.

Dietary sources of vitamin B2 include fortified breakfast cereals, beef liver, oats, plain yogurt, portabella mushrooms, spinach, whole eggs, clams, apples, cheese, and tomatoes.

Riboflavin is also widely available as a dietary supplement, both on its own and in B vitamin complex products. In some cases, supplementing your diet with a good vitamin B2 supplement can be beneficial.

Riboflavin Uses

  • Iron absorption: Iron is an essential mineral for the growth of cells and tissues as well as transporting oxygenated blood from your lungs throughout your body. If you are deficient in iron, you may suffer from anemia. Anemia results in fatigue, weakness, difficulty breathing, leg cramps, and insomnia. Riboflavin can help the body to absorb iron more readily, potentially helping lower the risk of iron deficiency.
  • Red blood cells: Riboflavin supports red blood cell formation and helps the body maintain a healthy ratio of red blood cells.
  • Energy: Riboflavin is needed for the breakdown of proteins into fats, acids, and carbohydrates to provide the body with energy. Vitamin B2 is also necessary to support proper thyroid and adrenal functions. A vitamin B2 deficiency can increase the risk of thyroid disorders.
  • Hair and skin: Riboflavin plays an important role in maintaining healthy collagen levels. Collagen is a protein found in the skin which helps to give it structure and help avoid the appearance of fine lines and wrinkles. A riboflavin deficiency can cause the skin to age quicker.
  • Headaches: Children and adolescents who are deficient in vitamin B2 may experience severe headaches and even migraines. In these cases, adding riboflavin to the diet can improve headaches. In one study, 55 patients who took between 200 and 400 mg of riboflavin daily experienced fewer and less intense headaches than those who were given a placebo.
  • Homocysteine levels: Homocysteine is an amino acid which the body creates during metabolism, which means you can only obtain it through your diet. In high concentrations, it has been linked to an increased risk of strokes and heart attacks. Vitamin B2 helps support healthy homocysteine levels.
  • Eye health: Riboflavin supports eye health by strengthening the lenses of the eye. The Blue Mountains Eye Study assessed 2873 participants taking multivitamins. The results revealed that along with other vitamins, riboflavin may help to reduce the risk of cataracts.

It’s important to note that many potential vitamin B2 benefits only really apply if you are already deficient in the vitamin. In other words, if you eat a healthy, balanced diet you may be getting enough riboflavin naturally – in which case, you may see little to no benefit from taking a top riboflavin supplement. With that said, the vitamin is water soluble, so you can’t have too much of it, and there are very few side effects – so there is little harm in trying it out.

How to Take Riboflavin

Vitamin B2 is considered safe when taken orally. The recommended dietary allowance (RDA) is 1.3 mg for adult males and 1.1 mg for adult females. Pregnant women are advised to take 1.4 mg per day. Breastfeeding women are advised to take 1.6 mg per day.

For improving vitamin B2 deficiency, a riboflavin dosage of 5-10mg per day is recommended.

To support healthy homocysteine levels, 1.6 mg of vitamin B1 is recommended for a period of 12 weeks.

For eye health, 3mg of riboflavin per day combined with 40 mg of niacin is recommended.

For headaches, 400mg of vitamin B2 for a period of at least three months is recommended.

Riboflavin Side Effects and Precautions

Riboflavin is a water-soluble vitamin, so it cannot be stored in the body. There is no upper limit for intake levels that is likely to be dangerous. Some people may experience side effects such as discoloration in their urine; this is not harmful.

What to Look for in a Good Riboflavin Supplement

Look for a vitamin B2 supplement that does not contain unnecessary fillers, artificial colors or flavors and that uses organic or non-GMO ingredients. You also need to choose a riboflavin supplement that provides an effective therapeutic dose.
