Vitamin B12 is an essential nutrient that we need to maintain nervous system function and overall health. It’s also a very popular dietary supplement, even though most people can get enough of it from foods.<\/p>\n
Vitamin B12, also known as cobalamin, is one of the eight B vitamins that make up the “B complex.” This family of vitamins plays an important role in nervous system function, energy production, cellular metabolism, skin health and more. <\/p>\n
Each B vitamin has a unique job in the body. Vitamin B12 is essential to maintaining healthy nerve cells, maintaining the myelin sheath around nerve fibers and supporting the function of neurotransmitters, per the National Institutes of Health<\/a>. B12 also supports the production of red blood cells and acts as a cofactor for reactions that synthesize and repair DNA.<\/p>\n While vitamin B12 doesn’t directly boost energy \u2014 although the supplements are often marketed to do exactly that \u2014 it does help the body break down food into usable energy, aka glucose.<\/p>\n B vitamins <\/a>are water-soluble vitamins, which means after the body uses what it needs, any excess B vitamins are excreted in urine, Katherine Zeratsky, a registered dietitian at the Mayo Clinic, previously told TODAY.com.<\/p>\n The body can store a few years’ worth of vitamin B12 in the liver, according to the National Library of Medicine<\/a>, but it will eventually need to be replenished.<\/p>\n Vitamin B12 is naturally present in many foods, added to fortified products, and available in supplements. It’s also added to most multivitamins. Given its prevalence, how much vitamin B12 do you really need per day?<\/p>\n Vitamin B12 Recommended Daily Intake<\/p>\n The recommended dietary allowance (RDA) for vitamin B12, measured in micrograms (mcg or \u00b5g), varies by age and health status. Here’s how much vitamin B12 you need, per the NIH<\/a>: <\/p>\n Are You Getting Enough Vitamin B12?<\/p>\n Most healthy adults can get enough vitamin B12 from eating a varied diet and do not need to take a supplement, TODAY.com previously reported.<\/p>\n However, some people are not able to get enough vitamin B12 due to dietary restrictions \u2014 namely, vegetarians and vegans, because most vitamin B12-rich foods are animal-based and plant sources are very limited, registered dietitian Valerie Agyeman told TODAY<\/a>.<\/p>\n Older adults may be at risk of deficiency because they have a harder time absorbing vitamin B12. Certain health conditions can also lower vitamin B12 levels, such as gastrointestinal diseases, certain medications and excessive alcohol use, per Medline Plus<\/a>.<\/p>\n These groups may benefit from taking a vitamin B12 supplement \u2014 but always talk to your doctor first.<\/p>\n Otherwise, most people can increase their vitamin B12 intake by eating more foods rich in this micronutrient.<\/p>\n Vitamin B12 Foods<\/p>\n Vitamin B12 is found primarily in animal foods and added to some fortified plant-based foods. Here are some of the best vitamin B12 foods to add to your diet:<\/p>\n Clams<\/p>\n Seafood<\/a> is excellent for overall health, registered dietitian-nutritionist Frances Largeman-Roth previously told TODAY.com.<\/p>\n Clams,<\/a> in particular, are packed with nutrients.
