Bottle Conditioned Sediment

Q

I would really appreciate some clarification concerning the sediment in the bottom of bottle-conditioned beer. Several years ago, and I can’t remember the source, I read that the sediment contained beneficial vitamin B along with antioxidants, and maybe a few other beneficial compounds. So I always swirl the last few ounces in the bottle before pouring. The other day while reading the neckband on a bottle-conditioned beer it said to pour gently so as not to disturb the sediment. Would you please give me your input on the whys or why nots about this?
