Vitamin B2: your body's energy essential

Tired of feeling tired? Discover the health benefits of vitamin B2, one of the essential B vitamins we need in our daily diet.

Like all eight B vitamins, B2 is essential for helping you convert food into energy so your body works efficiently.

And vitamin B2 – also known as riboflavin – is a must for keeping your skin, eyes and nervous system healthy.1 Plus, it helps turn fellow B vitamins, folate and B6, into forms your body can use.

B2: the energy vitamin

Running on empty? Vitamin B2 helps to break down fats, proteins and carbohydrates, and keeps a steady supply of energy flowing through your body.

It can also convert carbohydrates into a substance called adenosine triphosphate (ATP), which helps store energy in our muscle cells until we need it.2

B2 may help you feel less tired

Not getting enough vitamin B2 also reduces how much iron your body absorbs. We need iron to produce the red blood cells that carry oxygen to our organs and tissues. Low iron levels impact on our energy levels by triggering symptoms like fatigue, and can even lead to anaemia.3

It’s a secret antioxidant

It’s a little-known fact that B2 is an antioxidant, like vitamins A, C and E. This means it helps your body deal with oxidative stress – the damage from free radicals that has been linked to conditions such as heart disease.4

Essential for good eyesight

Vitamin B2 helps prevent our eyes sensitivity to light, while some studies suggest the nutrient could also help you see in the dark.5 A 2003 report, published in the American Journal of Clinical Nutrition, found that a lack of riboflavin may lead to night blindness. Scientists think there are photoreceptors in the eyes that need riboflavin to help adapt to darkness, and that it may work with vitamin A to improve our night vision.6

Are you getting enough vitamin B2?

Like all B vitamins, B2 is water-soluble so it’s not stored in your body. If you have a vitamin B2 deficiency because you’re not getting enough from your diet, you might notice some of these symptoms:
• fatigue
• sensitivity to light
• tired eyes
• digestive problems
• cracks at the side of your mouth
• a swollen tongue
