Sources Of Selenium
|Seafood -||oysters, tuna, mackerel, herring, lobsters, scallops, shrimp, pike, trout, carp, cod, flounder, salmon|
|Meats -||liver, kidney, heart, beef, lamb, egg, pork|
|Nuts/seeds -||brazil nuts, cashews, peanuts, walnuts|

|Miscellaneous -||brewer's yeast|
Roles In The Body
- At the molecular level selenium as a sulfhydryl agent, anti-oxidant (glutathione peroxidase), and as a synergist to vitamin E.
- At the cellular level selenium is involved in the destruction of peroxides, protection of cell membranes, as an electron transfer agent, and in glutathione metabolism.
- Selenium helps maintain the circulatory system, digestive organs, and reproductive system. It is also involved with heavy metal detoxification.
Functions Of Selenium
|Circulatory -||needed for the heart muscle|
|Excretory -||protection from toxic metals|
|Respiratory -||involved in oxygen transport|
|Digestive -||intestinal homeostasis|
|Nervous -||protection from mercury and cadmium|
|Reproductive -||protection against birth defects|
|Endocrine -||synergistic with the sex hormones|
|Blood -||stabilizes the red blood cell membranes|
|Integumentary -||helps maintain hair, skin and nails|
|Immune -||enhances immune system in animals|
|Metabolic -||lipid and sulfhydryl metabolism; may prevent liver necrosis|
|Detoxification -||helps remove mercury, cadmium, silver, arsenic and peroxides|
Nutrients That Are Synergistic With Selenium
|Metabolic -||vitamin C, vitamin E, glutathione|
|Absorption -||amino acids, peptides, proteins|
|Metabolic -||silver, arsenic, mercury, cadmium, titanium|
|Absorption -||copper, mercury, silver, sulfate|
Hair Analysis Notes
High Hair Selenium:
- can be due to the use of shampoos containing selenium
- may indicate a loss of selenium through the hair
Low Hair Selenium:
- may be due to dietary deficiency, which is relatively common, especially among those who eat refined foods
Reasons For Selenium Supplementation
Selenium may be given to help prevent or correct cadmium, mercury, or arsenic toxicity. Selenium is an anti-oxidant and may be given to help protect against free radical damage. Note that excessive selenium supplementation may be toxic.
In addition, there is extensive research presently being conducted on the functions of selenium and iodine with regard to thyroid function and it is becoming clear that there is an interaction between the two that should be noted.
