Well i feel it's the biggest marketing scam by the food industry, so that should tell you my thoughts on it.
I work in the food processing industry, and have for 20 years. I happen to know a great deal on the subject of quality control and GMP.
I wouldnt ever waste my money on it. 2 to 3 times the price for the same thing. For those that want to, more power to them. Not me.
