Otherwise, the nutrients will probably end up in the toilet. This is why taking a little of this nutrient and some of aother will not be effective. The same is true when you try to combine different bottles of nutrients from different companies. They are usually not in the right ratios. An example of how nutrients work together is iron and copper.
Copper regulates iron levels in the body.
If copper is not present in the right ratios, when iron approaches the cell, iron does not get in. You could then end up with such problems as anemia. Calcium requires six nutrients with it in order to get into the cell. In fact, because our foods are picked green, shipped long distances, processed, and then are cooked, we just don't get the nutrients from our foods as we used to. Every time the cell eats, it leaves behind waste material.
