This is what's holding us together. From our skin, the largest organ of detoxification, to our subcellular membranes, we are made up of structures. Most of us don't think about it much, unless we are training for a race, taking up powerlifting, or have recently discovered we have leaky gut. The repair and maintenance of these inner and outer structures is going on all the time. This is an area we often see very affected by nutritional deficiencies.
