Main Dietary Sources of Vitamin B6 and Vitamin B12
Animal-Based Foods as Key Sources of Vitamin B12 and B6
Animal-derived foods are the primary dietary sources of both vitamin B12 and vitamin B6. Studies consistently show that meats such as chicken, beef, and fish (including sardines, tuna, salmon, mackerel, and roasted trout) are significant contributors to vitamin B12 and B6 intake. Dairy products like cream and cheeses (Edamer and Feta) also provide substantial amounts of these vitamins. However, some fish and shellfish, while rich in B12 and B6, are less commonly consumed in certain populations, which can affect overall intake levels Serdarević2019Requejo2021Olsen2009+1 MORE.
Plant-Based and Other Sources of Vitamin B6
While vitamin B12 is almost exclusively found in animal products, vitamin B6 is present in a wider variety of foods. Besides meats and dairy, vegetables and cereals also contribute to vitamin B6 intake. In some populations, vegetables and cereals are notable sources, though meats and their derivatives remain the leading contributors Requejo2021Olsen2009Santos2023.
Population Studies on Vitamin B6 and B12 Intake
European and U.S. Dietary Patterns
Large-scale studies across Europe and the U.S. confirm that meat is the most important source of both vitamin B6 and B12 in most diets, except in specific groups such as vegetarians, who may have lower B12 intake . In Spain, for example, 97.4% of vitamin B12 intake comes from animal-based foods, while 26.6% of vitamin B6 comes from meats, with vegetables and cereals also making notable contributions .
Risk of Deficiency
Despite the availability of these vitamins in common foods, a significant percentage of people, such as university students in Sarajevo, do not meet recommended intakes for vitamin B12 and B6, highlighting the importance of dietary diversity and awareness Serdarević2019Requejo2021.
Conclusion
In summary, the main dietary sources of vitamin B12 are animal-based foods, especially meats, fish, and dairy products. Vitamin B6 is found in a broader range of foods, including meats, dairy, vegetables, and cereals, but animal products remain the most significant contributors in most diets. Ensuring adequate intake of these vitamins is important for health, and individuals who avoid animal products should consider fortified foods or supplements to meet their needs Serdarević2019Requejo2021Olsen2009+1 MORE.
