causes of low alkaline phosphatase levels
Malnutrition is the most common cause of low alkaline phosphatase. In particular, inadequate consumption of vitamin B6, folic acid, vitamin C, zinc, and magnesium are the most common nutritional causes, along with excess consumption of vitamin D.
Alkaline phosphatase is an enzyme produced by the body to help break down certain types of molecules, such as proteins. The liver produces most of the alkaline phosphatase in our bodies, but the intestines, kidneys and bones produce small amounts, too. Alkaline phosphatase is measured by blood testing. Called the ALP test, it is useful for diagnosing several diseases and conditions. For example, high ALP levels can indicate blocked bile ducts in the liver, bone disease or Celiac disease. Low ALP levels can indicate certain types of anemias or, rarely, specific types of cancer. It's worth noting that oral contraceptives (birth control pills) also can cause low ALP levels.
