answer
Talk to your doctor about whether you need to take a vitamin B12 supplement while on birth control. Some studies indicate that birth control pills can lower vitamin B12 levels but usually not enough to cause symptoms of vitamin B12 deficiency.

Some doctors recommend that women who take birth control pills also take a vitamin B12 supplement if they are deficient in the nutrient or if they follow a very restrictive diet that doesn't provide much vitamin B12. That nutrient is found in foods that come from animals, such as meat, poultry, fish and eggs. You and your doctor can discuss what's best for you.
