Men who take vitamin B supplements at greater risk of lung cancer


As per the new study, men who take high doses of vitamin B supplements like Vitamin B6 or B12 are at high risk of getting lung cancer as reported in daily Mail.

The B complex vitamins help red blood cells to process proteins, fats and carbohydrate. Vitamin B complex is available in natural foods like meat, fish, cheese, eggs, milk and cereals. But many people take supplements that are marketed as energy boosting products.

A study called Vital was carried out by the American researchers who examined 77,000 people aged between 50 and 76. Their aim was to understand the impact of vitamins and minerals on cancer risk.
