No need to buy very expensive imported vitamins, honestly. Most government-approved local brands have the exact same folic acid and iron content and work beautifully. Just take the one your local doctor writes for u.
Honestly, there is no single 'best' brand for everyone. My gynac told me that the composition of folic acid, iron, and B12 is what actually matters, so they prescribe based on your specific blood reports. Always let your doctor choose the brand for u.
Listen, don't ask people on the internet for medicine names. Every pregnant woman's body needs different dosages of iron or folate. Just show your reports to your doc and buy exactly what they write on the prescription.
I think it's always best to ask your gynac for this, dear. They know your health best and will give you the right brand. Don't worry, just take whatever they suggest.
Because of my PCOS, my vitamin requirements were slightly different, and I had to be very careful. I didn't want to take random suggestions online, so I just stuck strictly to what my doctor prescribed. It's much safer to consult your own doctor, sis.
