A truly awesome product indeed there are not many products of this quality with so many great compounds in them. I noticed an increase in my immune system straight away I live in a houseshare and everyone in the house was sick and I was the only one who didn't get sick and still went to work and the gym etc. Energy levels have also been good even though I have only been taking two a day. It is an expensive product I won't say it isn't but how much is your, mind, body and health worth.
