I have been using all 3 for just over a week now. I have already noticed an increase in my energy levels and not feeling so sluggish. It's too early to comment on changes to the skin. The taste is ok, I normally put in vegie juice or smoothie so it's pretty palatable. The sleep is nice and it has helped with a better sleep. It does have a chai flavour with hints of cholate and vanilla but it's not too strong so find it easy to drink. Would buy again.
