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.
