I tried multivitamins for years but they never had the effect that I desired and recently I've read studies that show multivitamins can sometimes do more harm than good because they are not in the proper ratio that mother nature intended. Our bodies are WAY too complicated for us to know everything that goes on, so the only logical supplement would a be a whole food based supplement. I take a whole food supplement called juice plus. I've been taking it for over 3 years and I can say that health wise its truly changed my life. Its the equivalent of 17 whole fruits and vegetables in capsule form. The research behind this product is astronomical, their may even be a really famous insurance company that may soon be recommending it because of the millions they'd save in claims from sick people. Its also backed by some of the most prestigous Dr.'s and people from the healthcare industry. Anyways, just saying it cause there have been studies recently released that show multi vitamins may actually do more harm than good, because the ratios are not in proper balance in your body. Anyways this stuff has made all the difference in an aging man's life and just wanted to share it with ya'll. This stuff is the dick. Email me if you want more info on it. There are tons and tons of research reports I can send you. regards, latlover
