There are several “pros” to any discussion of probiotics. For starters, consider that Global Industry Analysts predicts global sales of probiotic-enhanced products will surpass $28.8 billion in annual sales by 2015.
Not to be too contrary, but a study published in Nature finds consumers might be misinformed about probiotics in general. Specifically, Nature’s report targeted probiotics’ claim to improve digestive health and boost the immune system. The problem, study authors contended, was that these probiotics are seldom, if ever, tested to confirm the benefits.
