Vitamin B12 (aka cobalamin) is a vitamin that plays an important role in red blood cell production, brain health, and DNA synthesis.
A lot of the time, B12 needs are easily met with food, but 6 percent of people under 60 can still have a deficiency. Luckily, you can supplement vitamin B12 by taking a multivitamin — or take it solo with a soft gel, capsule, dissolvable tablet, gummy, or even liquid spray.
If you need a B12 boost, here are the best vitamin B12 supplements, plus tips for choosing the right supp for you.
