Are the ideas that he explained on PBW old concepts or is this some break through in workout nutrition?
Is he just trying to promote his product and are there other products on the market similar to his?
I know very little about sports nutrition, but what he said made a lot of sense. He sounds very sincere too.
The theory is sound
But with supplements the theory is usually NOT the problem. Your concern should be in the quality of the product, what's in it, does it have the required amounts and will these ingredients do what Milos' wants in the body according to the "theory".
Which is where most supplements fall short.
Take for example L-Carnitine...it makes sense that since carnitine is used to shuttle FA's into the mitochondria for energy, then higher levels of carnitine should move more fat for energy right...but when you consume it orally
... again, in theory it's great.
And the list goes on with supplements created based on theory...supplement companies know that they can capitalize on ignorance FOR A WHILE...so when that one bad study was done on Chromium Picolinate, every company produced it, until people started realizing it didn't do s*** and no other scientists could reproduce the results from that first "fake" study. So the companies move on to the next "fad" supplement...and so on.
Mind you, I'm not saying Milos is doing this, although I wonder who manufactures his products, rather I'm saying you're asking the wrong question.
