Get to know your B vitamins: Meet vitamin B2, also called riboflavin. B2 is one of eight B-complex vitamins. These vitamins work together to change carbohydrates from foods into fuel for your body. Vitamin B2 also helps release energy from proteins....CONTINUE READING
In other words, riboflavin takes your whole-wheat bagel and cream cheese and turns it into energy to get you through that next meeting (even if it could have been an email).
“Riboflavin is an essential micronutrient
that helps cells develop and work well,” says registered dietitian Kayla Kopp, RD, LD. “Healthy bacteria in your gut microbiome
make small amounts of riboflavin. But your body needs more to function. That’s why it’s important to get enough of this B vitamin in your diet every day.”
Your body needs vitamin B2 (riboflavin) to break down carbohydrates
from foods. This process helps your cells get the energy they need to function.
Studies suggest vitamin B2 also offers these four health benefits:
Researchers believe there may be a link between riboflavin, mitochondrial cell function and migraines. Mitochondria are your body’s energy makers. Riboflavin may also ease stress
and minimize nerve inflammation that contributes to migraines
.
In one study
, people who took 400 milligrams of vitamin B2 every day for three months had fewer migraines each month than those who took a placebo
. A different study
found similar effects in children. Even better, the children saw a decrease in migraine pain for up to 18 months after they stopped taking riboflavin supplements.
Based on findings like these, the American Academy of Neurology and the American Headache Society say people with chronic migraines may benefit from taking daily riboflavin supplements as a preventive measure.
Some experts believe that riboflavin prevents cancer-causing substances called carcinogens from damaging cells. But research findings are mixed.
A Women’s Health Initiative Observational Study
found that participants who got more riboflavin in their diets had a lower risk of colorectal cancer
. But other studies haven’t shown a link between the two.
Another study
investigated the effect of riboflavin on the risk of lung cancer
in people who smoke. But the findings were inconclusive, and the researchers said the results needed more investigation.
“If you’re at risk for certain cancers due to family history or other factors, talk to your healthcare provider to see if you should increase your intake of riboflavin,” advises Kopp. “And, of course, get the screenings and tests your provider recommends.”
A diet rich in vitamin B2 and other B-complex vitamins may lower your risk of cataracts
. These cloudy areas on your eye lenses cause vision problems
, such as blurred or double vision. People with severe, prolonged vitamin B2 deficiency are most at risk for developing cataracts.
Riboflavin helps your body absorb iron
. Not getting enough riboflavin puts you at risk for iron-deficiency anemia
.
“People with anemia may feel extremely tired, look pale and bruise easily. They don’t have enough iron to make healthy red blood cells,” explains Kopp. “ Red blood cells
carry oxygen throughout your body.” Pregnant people and children are most at risk for anemia due to riboflavin deficiency.
The amount of riboflavin or vitamin B2 (measured in milligrams or mg) you need each day depends on your age, sex assigned at birth
and whether you’re pregnant or breastfeeding.
