B12 Turbo

"I've been taking this supplement for about 3 months now and I can't say that it has improved my energy levels. I knew in the first month that I wasn't experiencing "increased productivity" or anything that it promises, but I decided to stick with it to give it a fair shot. I still experience that middle of the day sluggishness even though nothing else in my diet or lifestyle have change. I tried taking this supplement out of my diet and I couldn't tell a difference in my energy levels and stress. If you are looking for a vitamin B supplement, this is good to try but I wouldn't recommend it if you're hoping to experience what is supposedly does. Good marketing though."
