Here's where I admit to something:

http://www.magneurol.com/

I tried it for 45 days, along with regular iron and vitamin C taken at separate times. The idea was that the "magneurol" pills will be used by the body as regular iron if its supply of regular iron is low. The pills are a form of the mineral magnetite, used in traditional Chinese medicine, some B vitamins, and other nutrients you might see in an energy drink. My conclusion was that these pills are probably great for people just getting started, but that if you have been working with your energy body for a few years it is useless because your concern has shifted to the energy body and the physical has been trained enough to get out of the way more readily.
