This is the third time I've used these prenatal vitamins. I've only used one other kind so I can't really compare them with anything. They are a little large, but I don't have a problem with them. Others might have difficulty swallowing. They don't upset my stomach like I've heard of vitamins doing. They weren't too expensive and the bottle I got is huge so they'll last through my pregnancy. My hair and nails are growing very fast, so that's a plus unless you want them short. The only downside I've noticed is that I'm a little less regular, and it may be because of the vitamins because nothing else has changed in my diet or routine. Other than that, they seem to work great!
