You buy these at a health food store?
I've been buying them at the Vape Store where I get cigarettes for the past year or so, because the owner gives me a deal. He doesn't actually carry the stuff, he gets it just for me when he goes wherever he goes to get his merchandise.
My son keeps telling me to get it at Winco because it's cheap there, but Nuri (the Vape Store guy) gives it to me for the same price, and Winco's kind of hard to get to from here.
I doubt very much that I'd find them in a health food store. That industry has given NRG drinks a really bad rap, including 5hr.
Again, it contains vit B12, B6, Niacin, and Taurine. Our own bodies produce Taurine. It's an amino acid that helps control high blood pressure, blood glucose, and cholesterol, aids bile acids and the development and function of skeletal muscle, stabilizes the membrane of nerve tissues, and it's an antioxidant.
The energy surge only lasts me about 4 hours, and I'm cool with that. But if I have something going on in the evening, I'll sometimes drink an additional half a bottle in the early afternoon, or sometimes I'll drink my one bottle later in the morning than usual.
