It addresses the impacts of copper deficiency and excess, the complexity of evaluating copper status through serum levels and ceruloplasmin, and introduces potential markers like cuproenzymes and chaperones, which pose measurement difficulties. External factors affecting these indicators further complicate assessments of copper status.

Deficiencies can cause rickets and osteoporosis. Vitamin D is produced in the skin from sunlight or sourced from certain foods, including fortified options. Assessment of vitamin D status relies on 25-hydroxyvitamin D levels, whereas calcitriol levels indicate temporary changes. Research on vitamin D's non-skeletal functions is still limited.
