Is it ok to take multivitamin tablets? will there be any side effects? what are advisable multivitamin brands in singapore?

Yes, possibly and...: I advise everyone to take a high quality multivitamin. Side effects are uncommon- they could cause nausea if taken on an empty stomach. Some people might be allergic to potential ingredients like gluten or soy. Some brands are much better than others. I have no idea what brands are available in singapore.

Yes: Usually no side effects with good brands.Please check with the pharmacist for a good brand in singapore
