My surgeon swears by this brand and so I've used them exclusively since my surgery. All I can say is, you have to take vitamins after your surgery anyway so there's no escaping it, so I like these because they don't taste disgusting. Bariatric Advantage makes another multi where you only have to take 3 per day, but they're huge (not a problem for me) if that's a problem for you and the worst part is that they smell and taste so gross I just could not deal with swallowing them. It was all I could do to make it through the bottle. So these are smaller and you have to take 6 of them per day. But they don't smell or taste vile, so I wouldn't care if I had to take 12 every day because it's worth it.
