Factors that influence uptake: Bindes, Fiber, Soil Content, Refining/processing, mineral interactions (e.g. CA in spinach is bound by oxalate)
FE,ZN,CA-high fiber/phytic acid binds these esp.phytic acid in grains--->can be improved by yeast actin
Mineral-mineral interactin can decrease absorption, esp. when similar.
Toxicity potential is mainly caused from supplement with >100% |
