I just wanted to share an experience. I thought I would try a B-Complex Vitamin for some energy. Well the one I tried also had herbs in it and I didn't think much about them. I sure got a wake up call on this one. I got really depressed after taking them. I didn't notice much energy. I wasn't sure what was going on at first, then I made the connection with the herbs in the vitamin. I stopped taking it and I feel better. So, if anyone is thinking about taking vitamins and they contain herbs, make sure they won't affect you in a negative way.
