Oftentimes, when there is a significant level of inflammation throughout the cells that are lining the gut, our small intestines begin to lose the ability to effectively absorb the nutrients that are passing through in our foods and supplements. Additionally, any time we take anything “per oral” (i.e. by mouth), it must first be metabolized by our liver through what is called “First-Pass Metabolism,” which can often significantly lower the dose of the effective and therapeutic response that we receive. This is why “parenteral nutrition” (i.e. from a source other than oral), which bypasses our liver and intestinal tract, and is directly absorbed into the blood stream, can be of particular benefit in cases such as small intestinal bacterial overgrowth (SIBO), inflammatory bowel conditions, malnutrition / malabsorption, pancreatic insufficiency, and even in the case of multiple food sensitivities.
