Is it beneficial to take ferrous salt with folic acid while pregnant?

Depends. Eating beets and red cabbage will provide iron. Instead of synthetic folic acid, take l-methylfolate.
Yes. Many women are or can develop iron deficiency in pregnancy. The fetus requires iron to develop its hematologic and neurologic system, and will extract it from the mother even if the mother has little for herself. Taking supplemental iron is a good idea for most pregnant women for this reason.

Is it good to have a drink which contains soy protein, hi-maize, vitamin (a c B6 b12), thiamin b1, niacin b3, folate, (folic acid) sodium, potassium in pregnancy?

Not clear. You should certainly discuss it with your obstetrician if you become pregnant. If you are placed on a vitamin by your doctor while pregnant, you should consider stopping this supplement though. (Not sure if this is a routine in Australia, but it is in the United States) Regardless, your doctor's advice should be most important here. Good luck. Read more...

Too much inactive B6 can actually block active B6 from the B6 receptor, creating symptoms of B6 deficiency. Folic acid is synthetic, and too much can be bad also. Methylfolate and folinic acid are what one should take during pregnancy. Read more...
