Can anyone have twins?

The chances of having identical twins is relatively rare — around 3 or 4 in every 1,000 births. And while it may be obvious, identical twins are always the same sex, either both boys or both girls, at birth. Why? Well, they don’t just look alike — they also share the exact same DNA.

How do twins happen?

How twins are formed. Identical twins occur when a single fertilized egg splits into two. Fraternal twins occur when two, separate eggs are fertilized by two, separate sperm. Fraternal twins do not share the exact same genes — they are no more alike than they are to their siblings from different pregnancies.

How much folic acid is needed for twins?

“We recommend 1 milligram of folic acid per day for twin pregnancies and 0.4 milligrams for singleton pregnancies,” says Monga, who has twins. Folic acid is known to reduce risk of neural tube birth defects such as spina bifida.

Does 2 yolk sacs mean twins?

A single gestational sac observed with two heartbeats indicates a monochorionic twin pregnancy. Two gestational sacs indicate a dichorionic pregnancy. Although there is some debate on this matter in the reproductive medicine community, typically, if there are two yolk sacs, the pregnancy is diamniotic.

Is it OK to take 1mg of folic acid?

For folic acid deficiency: The typical dose is 250 mcg (micrograms) to 1 mg (milligrams) per day. For preventing birth defects of the brain and spine (neural tube birth defects): Women capable of becoming pregnant should take 400 mcg of folic acid per day from fortified foods or supplements.

Can I take two folic acid tablets a day?

You usually take folic acid once a day, but sometimes you only need to take it once a week. Most adults and children can take folic acid. If you’re pregnant or trying for a baby, it’s recommended you take folic acid until you’re 12 weeks pregnant.

Can I overdose on folic acid?

You can’t get too much from foods that naturally contain folate. You should not get more than 1,000 micrograms of folic acid a day, unless your doctor prescribes a higher amount. Too much folic acid can hide signs that you lack vitamin B12, which can cause nerve damage.
