In this study, researchers investigating the absorption of
copper in untreated patients who had damage to their duodenum
found anemia in 3 out of 10 of these patients that was due to
copper deficiency. They gave all the study subjects a solution
of copper to drink that was equal to a daily dose then tested
their blood level. Results showed that all 10 untreated subjects
had significantly decreased abillity to absorb copper compared
to normal subjects. “Copper Malabsorption in Coeliac Disease.”

Jameson S, Hellsing K, Magnusson S To investigate copper uptake
during three hours from an oral test dose of copper sulphate
solution. Copper intake during three hours from an oral test
dose of copper sulphate solution giving three mg Cu++ (copper),
close to the recommended daily dietary intake, was significantly
reduced in patients with proximal intestinal disease, compared
with normal subjects. Three out of ten patients had abnormal and
