Zipfizz seems to be one of those new vitamin type drinks. Many find with the incorporation of a bit of B vitamins, it boosts their energy levels.
Remember that it is synthetic additions and not great but not bad either per se.
I would rather see my visitors/clients utilize a nice organic greens powder which you can portion out yourself into small baggies. They are alkalizing, contain fresh organic ingredients which truly optimize the human body. There is a product out there called "greens to go" which I would recommend more so than this product.
