As a gastroenterologist, I’ve read a lot of research lately that promotes the use of probiotics in treating IBS and diarrhea caused by antibiotics. I’ve also read that probiotics are great to give children as it helps builds up their immunity. In response to the increased publicity of probiotics, a friend of mine recently approached me and said he'd like to start manufacturing probiotics supplements, along with a few other health supplements. But he wanted my endorsement on the one he is manufacturing. I would gladly help, but we both want to make sure that the probiotics supplements we manufacture would be high in quality and have active strains by the time it is ingested by the consumer. More often than not, this is not the case. Do any of you have a good brand you can recommend? What we're actually looking for is a quality contract manufacturer as well.
