These include chronic stress, poor diet, inadequate sleep, smoking, excessive alcohol consumption, pollution exposure, UV radiation, aging, and intense physical stress
A lack of energy can also disrupt these mechanisms
Digestive conditions like Crohn's disease and celiac disease create similar absorption problems
