Selenium has attracted attention because of its antioxidant properties. Antioxidants protect cells from damage. Evidence that selenium supplements may reduce the odds of prostate cancer has been mixed, but most studies suggest there is no real benefit. Selenium does not seem to affect the risk of colorectal or lung cancer. But beware: some studies suggest that selenium may increase the risk of non-melanoma skin cancer.

Among healthy people in the U.S., selenium deficiencies are uncommon. But some health conditions -- such as HIV, Crohn's disease, and others -- are associated with low selenium levels. People who are fed intravenously are also at risk for low selenium. Doctors sometimes suggest that people with these conditions use selenium supplements.

Selenium has also been studied for the treatment of dozens of conditions. They range from asthma to arthritis to dandruff to infertility. Selenium exists in two forms: inorganic (selenate and selenite) and organic (selenomethionine, Selenium-enriched yeast and selenocysteine). Both forms can be good dietary sources of selenium. Soils contain inorganic selenites and selenates that plants accumulate and convert to organic forms, mostly selenocysteine and selenomethionine and their methylated derivatives.

Lion’s mane mushrooms contain compounds that stimulate the growth of brain cells and protect them from damage caused by Alzheimer’s disease.

Lion’s mane extract has been shown to protect against stomach and intestinal ulcers in rodents

Animal and test-tube studies show that lion’s mane extract can kill cancer cells and slow the spread of tumors.

We added inorganic selenium to the hericium erinaceus culture medium, and when the fruiting body of hericium erinaceus matured, a large amount of organic selenium was enriched in the fruiting body of hericium erinaceus, while some inorganic selenium that was not absorbed continued to be retained in the medium.

Selenium and Hericium Erinaceus have many of the same functions, through this natural transformation, let its efficacy greatly increased.
