After I informed myself enough about the topic Vitamin care, I have the vitamin B complex tablets ordered me. The taste they are a bit strange and a bit floury taste me, what I find, however, not bad. An aftertaste, it has not left me. Now to the effect: I was amazed when I, amazingly better come out of bed the next day the tablet accommodating. I doubt it was a placebo effect, since this also covers the theory. I use it, however, not permanently, but always take it 2 weeks and set it down then, so that the body do not get too used to it. After 2 weeks of non-revenue I take it a re etc. Works for me very well so far. Do not regret this step. 5 Stars.
