Vitamin B is often touted as a healthy addition to anyone’s daily supplement regimen, especially for those who don’t eat the animal-derived foods that are full of B vitamins. A vitamin-B complex is known to increase your energy, help your skin and even boost your metabolism; however, a new study conducted at The Ohio State University Comprehensive Cancer Center (OSUCCC) states that there is now a “clear link” between B-vitamin supplements and lung cancer in men.

The study included more than 77,000 patients, all of whom were between the ages of 50 and 76 around the turn of the 21st century when the research began. After statistically adjusting for factors like alcohol consumption and family medical history, the results from the 10-year study showed that men who took vitamin B12 or B6 supplements were two to four times more likely to fall victim to lung cancer.

OSUCCC scientist Theodore Brasky, MD, made sure to highlight that the tie between vitamin B and lung cancer is not something one would experience from taking a daily multivitamin. Instead, the findings only express this link under the condition that the patients ingest a high dose of the vitamin daily, much higher than what a multivitamin offers.

Though the second factor shouldn’t come as a surprise, the study additionally found that being a smoker tripled the risk already observed from taking a vitamin-B pill.

While scientists currently say this effect is not present in women, a study is underway to ensure that there is no relation between vitamin B and lung cancer in menopausal women. For now, the connection is only observed in men who take a B6 or B12 supplement, especially for those who regularly smoke.
