What Is Vitamin B12?
Vitamin B12 is water-soluble that your body can’t make it on your own. It performs many essential functions in the body. And since your body can’t make it, you have to get it from animal-based sources or supplements. Vitamin B12 foods should be consumed often as our bodies can’t store it for a long time.
How Much Vitamin B12 is Recommended in Pregnancy?
The dietary requirement of this nutrient can increase manifold during pregnancy as the growing unborn baby may require it for its optimal development. Doctors generally recommend a supply of 3.5 ugs per day when pregnant to prevent deficiency of Vitamin B12. Therefore, a pregnant woman may need a dosage of 250 to 500 ug per day to meet her daily requirement. It is sensible to keep the dosage level on a slightly higher side to cater for the rate of absorption by the human body.
Vitamin B12 Supplements During Pregnancy
There are primarily two ways of obtaining vitamin B12. One is by consuming food items rich in the Vitamin and the second is by taking additional supplements.
Are They Safe?
It may be necessary to take supplements during pregnancy if a deficiency is assumed, to avoid any probable harm to the mother and the growing foetus. But the supplements should be taken in moderation. Therefore before taking any supplements, it is wise to consult a doctor who can suggest the right dosage for you. Your doctor may suggest injections or nasal gels for Vitamin B12 deficiency in pregnancy.
In any case, being careful while pregnant should be the norm. Overdosage may not be a desirable thing. Being a water-soluble nutrient, it may get excreted out of the body by way of urine in case of excess. It may be safe to state that suitable supplementation is protective and side effects of taking vitamin B12 supplements is highly unlikely.
When to Take
Most pregnant women may get their required supply from a nutritious diet and their prenatal vitamins.
