Choosing a Supplement 2007 May-June James Gerber, MS, DC The Journal of the American Chiropractic Association (JACA) Online
Abstract: Dr. James Gerber offers a simple outline of what is known about the value of vitamin and mineral supplementation, possible interactions, and amounts required.
I can understand why a chiropractor has a hard time choosing good products. Many use Quit Tea, http://www.quittea.com, so maybe the opinions of others would help. As well as the good margins.
