These are working for me - so much energy for all daily tasks - and more! And my wife is more satisfied) But, when I was eating 4 caps daily I've almost could not sleep at night. So, now I'm taking 2 daily - and it's enough! The quality of my life have changed dramatically - and I highly recommend these multi! Thanks, Thorne! Thanks, iHerb! vitamins first in my life, who work: in fact, have more energy, enough for all the daily (short-term) problem. However, after about three weeks after the beginning of reception of the multi, I reduced the dose - as a result, accept only 2 pieces per day. while taking four in a day, a couple of weeks to sleep practically ceased: energy is simply overwhelmed. I decided that such an effect once, and now adjusted. I recommend from personal experience.
