The Transdermal Absorption of Copper
The transdermal absorption of copper attracts the attention of science community. The advantages of copper absorption through skin are mainly observed through side effects of oral copper compounds, like nausea and vomiting, and the limited absorption of copper through oral intake due to:
​
1. Gastrointestinal disorders
2. Age-related physiological changes
3. Regional dietary deficiencies
4. An inappropriate diet
5. Inflammation
In evolution, the skin was the first organ that obtain food from the surrounding environment, long before development of the gastrointestinal system. According to theories, dermal optic photoreceptor is composed of red blood cells that, with high sensitivity, analyze elements on or near the skin in order to distinguish potential food from pathogens. It is believed that microelements can penetrate the skin by both push and pull factors (hunger), allowing absorption of microminerals when it is necessary for maintaining normal level in the body and prevention of deficiency and overdose.
According to Scientia Press, Australian scientists who studied the question found evidence suggesting that copper from bracelets does penetrate the skin and can have an ameliorative effect in rheumatoid arthritis.
