That is a good question Pam. Although the antibiotics aren't really nutrients, they are absorbed into the blood stream through the vascularized smooth muscle of our digestive tract. Most I think are metabolized in the liver and excreted by the kidneys. That is why tylenol can be so hepatotoxic. If you have been on antibiotics for a long time your body can become immune to them and you must seek a different treatment. I have Chronic Obstructive Pulmonary Disease, and I have been on antibiotics just about since June 6, 2004. For my lungs, it is a slow process, but for an ear infection or strep throat I recover as any other healthy person would. I hope this helps you in some way.
