Excellent Taste and Effective as Sublingual
 February 13, 2016
" The first time I put one of these under my tongue, I could feel the alertness difference within minutes. Have been using this daily since. I keep forgetting to make coffee now in the morning, because I do not feel as dragging and lethargic as I used to.
Taste is really good - and price is excellent. "
