In one embodiment, a composition containing ergothioneine and/or synthesized l-ergothioneine and one or more compounds selected from the group consisting of vitamin B-12, glucosamine sulfate, calcium ascorbate, turmeric extract, black pepper extract, hyaluronic acid, collagen, glycosaminoglycans, cat's claw extract, acai berry; and white willow bark extract is provided to a mammal to improve a variety of health related factors, including but not limited to brain health, joint health, eye health, mitondchorial optimization/improvement and reduction of inflammation and pain in a mammal.
A novel selenium-containing compound, a method of producing the selenium-containing compound, an analysis method using the selenium-containing compound, and use of the selenium-containing compound as an antioxidant, are disclosed. A novel selenium-containing compound shown by any of chemical formulas 1 to 4 is obtained by extracting a selenium-containing compound from a sample using an organic solvent or water, and purifying the selenium-containing compound. The novel selenium-containing compound may be used for a novel analysis method, or may be used as an antioxidant.

biological specimens, such as urine, whole blood, plasma, and saliva. From semiquantitative analysis results, the highest concentrations of hercynine were detected in saliva and whole blood, whereas much lower concentrations were measured in urine and plasma. Whole blood was the biological matrix with the highest concentration of l-ergothioneine followed by plasma, saliva, and urine. The antioxidant effects
