Public Questions: Vitamins in Pregnancy

Hi there...
Found your blog to be very informative! If you don't mind got a few questions need answering...
Vit A is teratogenic but beta carotene form is ok? Been taking pramilet for the last 4 months. Which form of Vit A is it in Pramilet? Thought the rec dose during pregnancy is 770mcg (~2400IU) but Pramilet v high. Is that ok? If Obimin is best should I change?
How about taking essential fatty acids while pregnant? Is it beneficial and what are the side effects? Heard DHA and Omega 3 particularly good for brain development but has it got any teratogenic effects. Like fish oil ..is it because of the vit A in it?

Ask the pharmacist

1) Beta carotene is metabolized to vitamin A, but the proportion converted to vit A decreases as beta carotene intake increases.So therefore no toxicity of Vit A. But u have to limit your daily beta carotene consumptions to 7mg max/day.
Studies have shown that supplying 20mg daily for 5-8 years to smokers will increase the risk of lung cancer, prostate cancer, stroke, heart attack etc. This is becoz smoking produce carcinogenic beta carotene oxidation metabolites. So for smokers out there, if u want to die faster, remember to take beta carotene. If want to live longer, pls stop smoking right now.

2) Vitamin A in obimin is higher than pramilet. Recommended daily allowance of vitamin A during pregnancy is 2700IU, although it shall be ok if u r not taking more than the max daily doses of 10,000 units.
Pls aware that this 10K units will include vitamin A from dietary units, esp animal liver, and even some breakfast cereal. Be extra careful in first trimester. Remember never to take 2 tablet of Obimin or Pramilet in one day. Always consult your pharmacist b4 choosing any supplements. As i say b4, if u r a healthy mother, there r no reason for u to take any extra supplementations also except folic acid.

3) Follow your dr recommendations would be the best choice in choosing supplementations becoz dr is the one who checked u. Of course u can always consult your pharmacist.

4) Essential Fatty acids is not necessarily to take during pregnancy. Insufficient evidence for its use.

Is it safe for me to take OBIMIN 1 tab once a day and 2 capsules of GNC Prenatal formula that contains 10000IU of Vitamin A(100% as beta-Carotene)? Thank you and your response will be very much appreciated.

taking obimin is already sufficient. Dont over supplement, it may bring more harm than benefit. Pls stop your GNC now unless your gyne ask u to take together.

Is is safe to take obimin pill one tablet in the morning and one tablet after dinner? I'm so worried about it after reading some thread that taking too much vitamin A will cause birth defects.
