The most recent Vegetarian Journal<\/em> takes a look at recent scientific literature on veggie diets. One topic covered is taking Vitamin B12 daily or weekly. Here\u2019s our write-up on this study:<\/p>\n\n\n\n

Vitamin B12 recommendations from\nmany vegan groups, including The Vegetarian Resource Group, are based on\ncalculating how much vitamin B12 is likely to be absorbed from supplements\ncontaining different amounts of vitamin B12. For example, in 2015 we said,\n“About 5% of the vitamin B12 in a supplement containing 25 mcg of vitamin\nB12 is absorbed. A lesser amount, 1% or less of the vitamin B12 in a supplement\ncontaining more than 100 micrograms of vitamin B12, is absorbed.”1<\/sup>\nA recent study examines whether these theoretical absorption rates actually\napply in vegans and non-vegan vegetarians.<\/p>\n\n\n\n

In this study,2<\/sup> 36\nvegetarian (including vegan) adults who were marginally deficient in vitamin\nB12 based on their blood vitamin B12 levels, were randomly divided into two\ngroups. During the 12 week study period, one group took 50 micrograms of\nvitamin B12 daily and the other group took 2,000 micrograms of vitamin B12 once\na week. Blood vitamin B12 was rechecked throughout the 12 weeks. Both groups’\nblood vitamin B12 levels improved as did other indicators of vitamin B12 status\nso that, at the end of the study, they were no longer considered to be\ndeficient. These results support recommendations to take vitamin B12\nsupplements either daily if you are using a lower dose (25-100 micrograms) or\nweekly for a higher dose of 2000 micrograms. One advantage of using a lower\ndose daily could be that you’re less likely to forget to take your supplement\nif it is part of your daily routine. On the other hand, taking a larger dose\none day each week, perhaps first thing Monday morning, may be easier for some\npeople to remember to do. In any case, it’s important to have a regular source\nof vitamin B12, whether fortified food or supplement.<\/p>\n\n\n\n
