Its in my pregnancy books but i've looked up info online for you to refer to
Iu is international units (don't know how many milli or micrograms that is but will search for you)
when you're trying to decide which prenatal vitamin is right for you, talk to your doctor or midwife abot their recomendations and keep some things in mind:
no prenatal vitamin will contain all of the calcium you need.
Too much vitamin a can cause birth defects, be sure that you're using a prenatal vitamin or a multi-vitamin with under 10,000 iu.
Too much iron in a prenatal vitamin will not be absorbed properly.
The taste and texture of vitamins do bother some women. If you can't keep your prenatal down, consider switching brands.
how do I convert international units (iu) to milligrams?
Iu stands for international units and is used for the measurement of drugs and vitamins.
Webster's defines iu as: a quantity of a biologic (such as a vitamin) that produces a particular biological effect agreed upon as an international standard
what this means is that iu is dependent on the potency of the substance, and each substance would have a different iu to milligram conversion. For example, 1000 iu of vitamin c would have a different weight than 1000 iu of vitamin a
since each substance would have a different conversion ratio, we cannot put up a conversion for iu to milligrams that covers everything, or even most things. Just too many different substances.
So what can you do?
Your best bet would be to contact your pharmacist. They have all the information anyone could ever want about drugs and vitamins.
You could also contact the manufacturer of the vitamin. Most manufactures will have a web site with contact information so you can email them. Try searching the web using the manufactures name or the name of the vitamin.
A good place to start your search is altavista or msn search.
But only every other day - guys make sperm "on demand" but having sex every day doesn't give the chance to build back up, so semen then contains less sperm per ml.
If you have sex every other day from around day9/10 then there should be plenty of sperm left hanging around waiting for the egg even f you don't have sex on the actual day of ovulation.
