“…Thus, 40 studies remained and were included in the review. The samples included in these studies consisted of a wide range of individuals at different life stages, including infants, 47 children and adolescents, 12,14,22,25,31 pregnant women, 27 adults [8][9][10]12,13,[15][16][17][18][19][20][21][22][23][24]26,[28][29][30][32][33][34][35][36][37][38][39][41][42][43][44][45][46] and the elderly. 11,12,40 Most studies included both sexes, but 10 studies assessed vitamin B12 status in female subjects only 8,17,21,24,25,27,33,40,…”

The prevalence of cobalamin deficiency among vegetarians assessed by serum vitamin B12: a review of literature

Individuals following vegetarian diets are at risk for developing vitamin B12 deficiency owing to suboptimal intake. As vitamin B12 is essential for the synthesis of nucleic acids, erythrocytes and in the maintenance of myelin, deficiency may result in a variety of symptoms. Some of these symptoms may be severe while others may be irreversible. The objective of this review was to assess vitamin B12 deficiency, based on reported serum vitamin B12, among individuals adhering to different types of vegetarian diets. A systematic literature search was carried out using multiple search engines including PubMed, Medline, CINAHL plus, ERIC, Nursing and Allied Health Collection and Nursing/Academic Edition. The inclusion criteria consisted of original studies that assessed serum vitamin B12, studies written in English, non-case studies and studies that reported actual percentages of vitamin B12 deficiency. Forty research studies were included. The deficiency prevalence among infants reached 45%. The deficiency among the children and adolescents ranged from 0 to 33.3%. Deficiency among pregnant women ranged from 17 to 39%, dependent on the trimester. Adults and elderly individuals had a deficiency range of 0-86.5%. Higher deficiency prevalence was reported in vegans than in other vegetarians. Thus, with few exceptions, the reviewed studies documented relatively high deficiency prevalence among vegetarians. Vegans who do not ingest vitamin B12 supplements were found to be at especially high risk. Vegetarians, especially vegans, should give strong consideration to the use of vitamin B12 supplements to ensure adequate vitamin B12 intake. Vegetarians, regardless of the type of vegetarian diet they adhere to, should be screened for vitamin B12 deficiency.

“…A meta-analysis of 17 studies that compared homocysteine and B12 levels in vegetarians (3230 LOV/LV/VEG) with those in OMN [106] found that VEG had the highest mean homocysteine values, and lowest mean B12 levels, while levels in LOV were intermediate between those of VEG and OMN. In only two of these studies were mean plasma levels of homocysteine and B12 similar to those in OMN [73,101].…”

Vitamin B12-Containing Plant Food Sources for Vegetarians

2014

View full text Add to dashboard Cite

The usual dietary sources of Vitamin B12 are animal-derived foods, although a few plant-based foods contain substantial amounts of Vitamin B12. To prevent Vitamin B12 deficiency in high-risk populations such as vegetarians, it is necessary to identify plant-derived foods that contain high levels of Vitamin B12. A survey of naturally occurring plant-derived food sources with high Vitamin B12 contents suggested that dried purple laver (nori) is the most suitable Vitamin B12 source presently available for vegetarians. Furthermore, dried purple laver also contains high levels of other nutrients that are lacking in vegetarian diets, such as iron and n-3 polyunsaturated fatty acids. Dried purple laver is a natural plant product and it is suitable for most people in various vegetarian groups.
