Vitamin B12


Vitamin B12, a water-soluble vitamin that also goes by “cobalamin,” wears many health-promoting hats. First, it supports the production of cellular energy, which you can think of as an invisible engine that keeps everything humming along. It also prevents megaloblastic anemia, where your body lacks healthy red blood cells and you end up feeling tired and weak. It also helps replicate DNA for healthy new cells. Whew…what a multi-tasker! You can get this busy B from red meat, chicken, eggs, fish, and dairy, but plant-based foods contain no vitamin B12 unless they’re fortified with it. That means if you’re a vegetarian or a vegan, you may want to take a B12 supplement or a multivitamin to make sure you're getting enough. (That advice goes for carnivores too!) Symptoms of a B12 deficiency include fatigue, weakness, numbness or tingling in the arms and legs, cognitive difficulties, depression, constipation, loss of appetite, and weight loss. All symptoms to have checked out!
