Recklessly adding a supplement to your diet can even be harmful.
A recent study scientists have found a significant link between a popular vitamin supplement and an increased risk of lung cancer.
For example, in 2021, the European Journal of Cancer Prevention found a strong link between vitamin B12 intake and lung cancer risk.
Vitamin B12 performs many important functions in the body, such as helping the development and functioning of the central nervous system .
Some people sometimes need to make up for a B12 deficiency, but thoughtlessly adding a supplement to their diet can even hurt.
The researchers in the study noted that «previous epidemiological studies have reported an association between dietary vitamin B12 intake and lung cancer risk, but more studies are now needed to clarify this association in different populations.
To To fill this gap, researchers examined the association between dietary vitamin B12 intake and lung cancer risk.
The study involved 63,257 Singaporean men and women aged 45-74 who supplemented with the vitamin.
What did the researchers find?
After a follow-up period (approximately 17 years), a 2001 study participant developed lung cancer.
High vitamin B12 intake has been associated with «significantly» increased risk of lung cancer.
Where Vitamin B12 is found
The vitamin is found in meat, fish, eggs, dairy products, yeast extract, and specially fortified foods.
