Vitamin B2 - riboflavin
What exactly is Vitamin B2?
Vitamin B2, also known as Riboflavin, is a water-soluble B vitamin that our bodies need to function properly. It is involved in many important processes, from energy production to protecting our cells from damage. Riboflavin helps break down foods, such as carbohydrates, fats, and proteins, to give us the energy we need to stay active throughout the day. Without this vitamin, we simply wouldn’t be able to use the food we eat effectively.
But Riboflavin is more than just an energy aid. It also plays a role in protecting our cells from free radical damage and inflammatory processes in the body.
It is also important for our skin, hair and vision. In other words, it is a vitamin that has a big impact on how we feel and how we look.
Why do we need Riboflavin?
Our bodies use Riboflavin in several ways, and it is involved in almost every cellular process. Riboflavin is converted into two active forms in the body – flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) – both of which help with energy turnoverThese two coenzymes are necessary for the body to be able to use the nutrients we get from food.
One of the most important things Riboflavin does is help break down the nutrients we eat, such as carbohydrates, fats and proteins. This is what gives us energy for everything we do, from getting up in the morning, going to work, to trudging up a small mountain, or even going to the gym and lifting something heavy.
Riboflavin also has antioxidant properties, meaning it can protect the body from free radical damage. This is important, because we're taught to eat blueberries and drink orange juice. But no, we have many mechanisms that protect our cells, without pouring on sugar at the same time.
When it comes to skin and eyes, Riboflavin is also at work. It can help maintain healthy skin and can prevent problems like rashes and skin ulcers. When it comes to the eyes, Riboflavin plays a role in protecting against problems like cataracts. So you could say that Riboflavin is a true all-rounder for our health.
What happens if we get too little Riboflavin?
Riboflavin deficiency can actually lead to several problems in the body. One of the first signs of deficiency is skin problems, such as chapped lips and an inflamed, red rash. People with Riboflavin deficiency may also notice that their tongue becomes sore and inflamed, a condition called glossitis. The eyes may also become red and irritated, and sensitivity to light may occur.
Other symptoms of deficiency include fatigue, weakness and even muscle problems. When Riboflavin is not available in sufficient amounts, the body can have trouble making enough energy, which can make us feel exhausted and lack stamina. In the worst case, a lack of Riboflavin can also affect the nervous system, which can lead to numbness and tingling in the hands and feet.
What can we eat to get enough Riboflavin?
Fortunately, it is quite easy to get enough Riboflavin, as it is found in many different foods. Dairy products such as milk, cheese and yogurt are some of the best sources, and most of us get our riboflavin from these every day. Meat, especially beef and chicken liver, is also incredibly rich in Riboflavin. Oily fish, such as mackerel and salmon, and eggs, especially egg yolks, are also good sources.
Plant-based sources of Riboflavin also exist, but our bodies have a slightly harder time absorbing Riboflavin from plant products than from animal sources. That doesn't mean you can't get Riboflavin from a plant-based diet, but you may want to make sure you include more of the aforementioned foods in your diet to get enough.
How much Riboflavin do we need?
The daily recommendation for Riboflavin varies slightly, depending on age, gender, and whether you are pregnant or breastfeeding. Adult women are recommended to consume 1,1 mg per day, while adult men should aim for 1,3 mg. Pregnant and breastfeeding women have a slightly higher need, so you may want to adjust your intake accordingly.
Since Riboflavin is a water-soluble vitamin, the body will get rid of excess through urine, so the risk of taking too much is very low. You probably won't have to worry about overdosing, even if you eat a lot of foods containing Riboflavin.
Is it dangerous to get too much Riboflavin?
No, as mentioned, Riboflavin is a water-soluble vitamin, so the body has a natural way of getting rid of any excess. You will notice that your urine may turn a light yellow color if you take in extra Riboflavin, but this is completely harmless and a sign that your body is doing its job of excreting what it doesn't need.
