As a consequence of the biochemical reactions in which homocysteine is involved, deficiencies of vitamin B 6, folic acid (vitamin B 9), and vitamin B 12 can lead to high homocysteine levels. [2] Other possible causes of hyperhomocysteinemia include genetics, excessive methionine intake, and other diseases. [3]
Vitamin B 12 deficiency is preventable with supplements, which are recommended for pregnant vegetarians and vegans, and not harmful in others. [2] Risk of toxicity due to vitamin B 12 is low. [2] Vitamin B 12 deficiency in the US and the UK is estimated to occur in about 6 percent of those under the age of 60, and 20 percent of those over the ...

Increased homocysteine levels suggest tissue folate deficiency, but homocysteine is also affected by vitamin B 12 and vitamin B 6, renal function, and genetics. One way to differentiate between folate deficiency and vitamin B 12 deficiency is by testing for methylmalonic acid (MMA) levels.
It’s rich in vitamins B6 and B12 as well as choline. ... the Centers for Disease Control and Prevention urges all women who are pregnant or trying to conceive to take folic acid supplements ...
In the body, homocysteine can be recycled into methionine or converted into cysteine with the aid of vitamin B 6, B 9, and B 12. [3] High levels of homocysteine in the blood (hyperhomocysteinemia) is regarded as a marker of cardiovascular disease, likely working through atherogenesis, which can result in ischemic injury.
The body needs enough intrinsic factor to absorb and reabsorb vitamin B 12 from the bile, the lack of which reduces the time needed to develop a deficiency. [49] B 12 is required by enzymes for two reactions: the conversion of methylmalonyl-CoA to succinyl-CoA, and the conversion of homocysteine to methionine.
