What is the relationship between folate and vitamin B12?
In one-carbon cycle, folate acts as a one-carbon carrier and vitamin B12 acts as co-factor for the enzyme methionine synthase. Both folate and vitamin B12 are the important regulators of DNA methylation which play an important role in development in early life.
Can you treat B12 and folate deficiency together?
Most cases of vitamin B12 and folate deficiency can be easily treated with injections or tablets to replace the missing vitamins. Vitamin B12 supplements are usually given by injection at first.
Should you take B12 and folate together?

What is the metabolic relationship between hemoglobin synthesis and folic acid deficiency?
Deficiency of folate or vitamin B12 inhibits purine and thymidylate syntheses, impairs DNA synthesis, and causes erythroblast apoptosis, resulting in anemia from ineffective erythropoiesis. Erythroblasts require large amounts of iron for hemoglobin synthesis.
Do you treat B12 or folate deficiency first?
Vitamin B12 supplements are usually given by injection at first. Then, depending on whether your B12 deficiency is related to your diet, you’ll either require B12 tablets between meals or regular injections. These treatments may be needed for the rest of your life. Folic acid tablets are used to restore folate levels.

What does vitamin B12 cobalamin prevent?
What is vitamin B12 and what does it do? Vitamin B12 is a nutrient that helps keep your body’s blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.
