[Olga]

Tell or Say the need or requirement of an organism for a calcium on early durations of gestation (4 weeks) is how much great. I accept vitamins vitrum-prenatal-forte 1 capsule in day, kaltsija-200 mg/tab, whether it is necessary still or even for something to accept, for example upsavit-kalitsium?
Thanks in advance...

In addition anything to accept it is not necessary.
