Unlike fat-soluble vitamins which can be stored in the liver and fatty tissues for future use, water-soluble vitamins are generally not stored in the body. Water-soluble vitamins circulate in the blood stream where they can be taken up by the tissues for immediate use or otherwise excreted. As such, it is important to consume adequate amounts of water-soluble vitamins, such as B-12, every day.
While vitamin B-12 is naturally found in animal products such as seafood, beef, chicken and eggs; it is not found in plant foods in any significant amounts.2 While fortified cereals may provide dietary vitamin B-12, fortified foods may vary in formulation so it is important to read product labels. Nature’s Bounty® Vitamin B-12 is vegetarian-friendly and provides the advanced, active form of vitamin B-12.
