Thank you for your question,
I’m Dr. Saha and I’ll try to help you.
There is a difference in the level of ingredients in prenatal vitamins than the other supplements.
Folic acid level is higher.
Iron is also more than the recommended daily allowance for your age.
However, if you suffer from iron deficiency, then you need to take more according to the deficiency.
I would to consult your doctor.
The cause of iron deficiency needs to be found out & treated accordingly.
Your calcium requirement is also higher than the prenatal vitamins usually provide.
So that amount needs to be adjusted.
I hope this information helps.
I will be happy to assist, if you need any clarification.
Please feel free for any follow up query.
