Foods with Vitamin B12
Vitamin B12, also known as cyanocobalamin, is an essential nutrient that may be linked with healthy brain function, cell formation, metabolic functions, and hormonal balance.* It is not produced naturally by the body and must be consumed through diet or supplements. A deficiency of vitamin B12 can cause symptoms such as fatigue, breathlessness, heart palpitations, and pale skin.* Meat and fish are good sources of B12 and vegetarians can be particularly at risk of a deficiency. B12 is a water-soluble vitamin and needs to be consumed most days since it does not get stored in the body.
B12 supplements are often included as part of a “B complex” supplement which includes other B vitamins, but can also be found as a stand-alone supplement.
The body needs vitamin B12 to convert carbohydrates into glucose, and a deficiency can cause fatigue and weakness.*
