10. B vitamins
Take into consideration that large amounts of B vitamins could be dangerous. As a matter of fact, men who regularly took larger amounts of B6 and B12 had higher risks of lung cancer, according to studies published in the Journal of Clinical Oncology.
Some individuals may benefit from a B complex, though: “If you are pregnant, have a compromised gut, are vegan/vegetarian, are taking certain medications, or are older, you may want to get tested to see if you need to supplement,” Sharafeddine says. You should stop taking B vitamins, because you can likely get an adequate amount of them through whole grains, dark leafy greens, fish, eggs, or poultry.
