Question

Quizplus · Accepted Answer

Deficiencies of vitamin B12, vitamin B6, and folate have been implicated in increased blood levels of homocysteine in the elderly. Iron deficiency may also contribute, but it is not specifically implicated in this process. Calcium and vitamin D deficiencies do not directly affect homocysteine levels. All the B vitamins and vitamin C can play a role in homocysteine metabolism, but vitamin B12, vitamin B6, and folate deficiencies are the most commonly cited culprits. Fat-soluble vitamins are not involved in homocysteine metabolism.
