What Is Riboflavin?

Riboflavin is a water-soluble vitamin that is essential for the growth and development of the body. Known also as vitamin B2, it plays a crucial role in the generation of energy from food, the maintenance of healthy tissues and metabolism. B2 is necessary for the production of red blood cells, the maintenance of healthy skin, mucous membranes, and eyes. This vitamin also helps improve digestion and supports the nervous system.

Riboflavin is essential in the production of two important coenzymes in the body, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These coenzymes are required by various enzymes in the body to perform their functions efficiently. FAD and FMN play a significant role in various metabolic pathways in the body, including the metabolism of fats, carbohydrates, and proteins.

Riboflavin has been known about for centuries, but it wasn’t until the 1920s that it was isolated, and its importance for human health realized. It has now become a staple nutrient in most diets worldwide. B2 is commonly found in dairy products, green vegetables, eggs, meat, liver, and enriched cereals.

Riboflavin is also crucial for maintaining a healthy nervous system, which can help improve your mood. This vitamin can help alleviate symptoms of depression and anxiety, making you feel happier and more energetic.

One of the most common age-related eye diseases is cataracts. Studies show that riboflavin can help reduce the risk of developing cataracts. This vitamin has strong antioxidant properties that can help prevent oxidative damage in the eyes, which is a common cause of cataracts. By adding riboflavin to your diet, you can protect your eyesight as you age.

Better sleep quality is essential since it improves mood, concentration, and memory. It’s ability to improve sleep patterns reduces the stress of parents and caretakers who are dealing with sleepless nights.

Good for Your Heart

It can also benefit your heart. Studies show that people with high riboflavin levels have a lower risk of developing heart disease. This is because riboflavin is important for maintaining proper levels of homocysteine, an amino acid that can damage your blood vessels if it’s not kept in check. By ensuring you get enough B2 in your diet, you can protect your heart and lower your risk of heart disease.

Boost Immunity

It is necessary to produce antibodies that help fight off infections. It also plays a key role in maintaining a healthy immune system. By ensuring you have sufficient levels of riboflavin in your diet, you can help prevent common infections and illnesses.

By making sure you get enough riboflavin, you can support your brain and keep your mind sharp.

It shows potential in reducing the frequency of migraine headaches. It has a direct effect on the mitochondrial energy metabolism, which is involved in controlling the symptoms of migraines. A number of studies have shown that taking riboflavin supplements can reduce the frequency and severity of migraines. The exact reason for this is still unknown, but it’s believed that riboflavin helps improve blood flow to the brain, which can reduce the risk of migraines.

Riboflavin Side Effects

Causes Diarrhea

Excessive intake of B2 shows to cause diarrhea in some people. This is probably because riboflavin plays a role in maintaining the lining of the digestive tract. Taking more riboflavin than your body can absorb can overstimulate this process, leading to diarrhea. To avoid this, make sure to take riboflavin supplements as prescribed by your doctor or healthcare provider.

May Cause Visual Disturbances

B2 can also cause visual disturbances, particularly tearing, eye sensitivity to light, and blurry vision. This effect can happen with high doses of riboflavin, which can interfere with the way the eyes absorb light. If you experience any visual disturbances after taking a riboflavin supplement, stop using it and consult your healthcare provider immediately.

Can Trigger Allergic Reactions

Sometimes, taking a B2 supplement can trigger an allergic reaction in susceptible people. This reaction can cause skin rash, itchy hives, swollen tongue, or difficulty breathing. It is essential to be aware of any allergic reactions, and if you notice any, consult your healthcare provider immediately.

May Increase The Risk of Kidney Stones

It can contribute to the formation of calcium oxalate stones in the kidneys. These stones can cause severe pain and discomfort when passing through the urinary tract. To reduce the risk of kidney stones, it is essential to stay hydrated and consult your healthcare provider on the right riboflavin dose for you.

Can Mask Other Health Issues

Lastly, taking excessive B2 can also mask other underlying health issues like vitamin B12 deficiency, which can lead to nerve damage. This is because riboflavin interferes with some diagnostic tests that measure vitamin B12 levels. To avoid this, discuss your health condition with your healthcare provider before taking any riboflavin supplements.

How Does Riboflavin Help Migraines?

Riboflavin works in our body by converting carbohydrates into usable energy. Deficiency in riboflavin can cause headaches and migraines. Riboflavin can increase brain cell energy and may reduce the frequency of migraines. Daily intake of riboflavin can manage migraines effectively over time.

The effectiveness of riboflavin on migraines varies depending on the individual, but should ideally work after 4-6 weeks of consistent dosage. Since riboflavin has no known side effects, there is no harm in continuing with the vitamin for long-term relief.

Riboflavin for Tinnitus

Riboflavin is essential for maintaining healthy cellular metabolism and energy production. But it also has vital roles in numerous bodily functions, from immune system functioning to maintaining healthy eyesight, and to prevent or reduce migraine headaches. Studies suggest that supplementing with riboflavin may help improve blood circulation to the inner ear and relieve tinnitus symptoms. Furthermore, riboflavin helps to neutralize free radicals that can contribute to the development of tinnitus.

Before taking riboflavin for tinnitus, it’s best to consult your healthcare provider. While riboflavin is generally considered safe, it may interact with certain medications, and consuming excessive amounts could lead to unpleasant side effects. Your doctor can give you proper dosage instructions for your individual needs.


The dose that you will require will depend on your reasons for taking riboflavin as a supplement. If you are a healthy adult using it for energy or athletic performance, a dose around 1.3 mg per day should be enough, although you can experiment with different doses to find one that works for you. If you are considering taking a high dose, speak with your doctor. In most cases, however, even high doses of riboflavin are safe.

If you are riboflavin deficient, you will need a higher dose and should consult with your doctor on what is best. And the dose will depend on whether you’re trying to prevent riboflavin deficiency or treat an already existing case of it, as well as the severity of the deficiency. Standard doses range from 5-30 mg per day.

For headaches, a significantly higher dose is in use, often from 300 to 500 mg per day. This dose is many times higher than that used for other health reasons, so you should speak with your doctor if you are considering using this as a treatment for your headaches.

Why Take Riboflavin

Many people will get enough riboflavin in their diets. After all, foods high in riboflavin include eggs, milk, meats, nuts, and leafy greens. These foods are commonly available, so you may wonder why you should consider supplementing with riboflavin.

The main reason? Food-based sources of the vitamin are not always consistent, meaning doses will vary. If you supplement with riboflavin, you can ensure that your body is getting the appropriate levels of the vitamin and not have to monitor your diet to make sure you are consistently getting enough. And since it’s water soluble, there’s little risk from using riboflavin supplements aside from side effects like increased urination and discolored urine.

It is a great vitamin for energy and can be an effective part of a supplement regime that keeps you going throughout the day — or give you more energy for workouts, keeping you from losing steam halfway through. However, if you do decide to take riboflavin, consider adding other B-vitamins. It is most effective as part of a B-complex, where all the vitamins work together to boost your metabolism and make the most of your food.
