Alright, I started a thread about this in the GD forum and got some non-satisfactory responses lol. So I thought I would come here and see if you guys are a little more helpful. I just recently started taking One A Day Mens multivitamins....I asked if anyone has had experience taking these or centrum and if they boost your energy levels and actually have positive health benefits. Well I was basically told that Centrum and One A day vitamins are basically useless because they are synthetic and not natural (which seems reasonable). SO I mean do any of you guys take a NATURAL vitamin that mainly boost energy levels and might have a few other benefits as well? Was the info they gave me about synthetic shit correct? I am a total rookie in this department and am looking for something that actually does increase energy and it would be nice if it had some other health benefits as well. Let me know guys and appreciate the input
