Determine the Factors that Influence manganese absorption?
Let us now see which factors influence Mn absorption.
Major factors which may influence the absorption of this mineral include:
-  Absorption decreases with increasing intake. 
 
-  Percent absorption is higher among women as compared to men. 
 
-  Increased dietary iron depresses Mn absorption whereas iron deficiency increases its absorption. This could be possibly due to the competition for similar binding and absorption sites between non-haem iron and Mn. 
 
-  High levels of dietary calcium, phosphorus and phytate impair the intestinal uptake of the element but these have been shown to be of limited significance.
