“…Both forms can be good dietary sources [ 181 , 183 ]. It is composed of more than two dozen selenoproteins that play important roles in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection [ 184 , 185 ]. Most selenium is in the form of selenomethionine in animal and human tissue [ 181 ].…”

The history of cosmetics goes back to early Egyptian times for hygiene and health benefits while the history of topical applications that provide a medicinal treatment to combat dermal aging is relatively new. For example, the term cosmeceutical was first coined by Albert Kligman in 1984 to describe topical products that afford both cosmetic and therapeutic benefits. However, beauty comes from the inside. Therefore, for some time scientists have considered how nutrition reflects healthy skin and the aging process. The more recent link between nutrition and skin aging began in earnest around the year 2000 with the demonstrated increase in peer-reviewed scientific journal reports on this topic that included biochemical and molecular mechanisms of action. Thus, the application of: (a) topical administration from outside into the skin and (b) inside by oral consumption of nutritionals to the outer skin layers is now common place and many journal reports exhibit significant improvement for both on a variety of dermal parameters. Therefore, this review covers, where applicable, the history, chemical structure, and sources such as biological and biomedical properties in the skin along with animal and clinical data on the oral applications of: (a) collagen, (b) ceramide, (c) β-carotene, (d) astaxanthin, (e) coenzyme Q10, (f) colostrum, (g) zinc, and (h) selenium in their mode of action or function in improving dermal health by various quantified endpoints. Lastly, the importance of the human skin microbiome is briefly discussed in reference to the genomics, measurement, and factors influencing its expression and how it may alter the immune system, various dermal disorders, and potentially be involved in chemoprevention.

“…Absorbed by the organism, it is bound by red blood cells, blood albumin and plasma globulin, and transported to tissues; between 28% and 46% of selenium is deposited in skeletal muscles (Terry & Diamond, 2012). Selenium occurs in both inorganic (selenates and selenites) and organic forms (selenomethionine and selenocysteine) (Sunde, 2006), and absorption from food depends on the chemical form.…”

“…This element is a component of approximately 20 enzymes, including glutathione peroxidase that protects the organism from oxidative damage. As a part of selenoproteins and selenoenzymes it is considered a strong antioxidant, which together with antioxidant vitamins plays a protective role against the harmful effects of free radicals [ 9 ]. Selenium is essential for the proper synthesis, activation, and metabolism of thyroid hormones.…”

“…Furthermore, selenium reduces the toxic effects of some xenobiotics, especially heavy metals, converting them to stable, less toxic forms. There is only a small difference between the recommended (55 μg) and the toxic dose (>400 μg) of selenium [ 9 , 13 ]. Therefore, deficiency and redundancy of selenium are both dangerous for the human body [ 9 ].…”

The nutritional value of gluten-free products is the subject of interest for food technologists and nutritionists, as the only effective treatment for celiac disease is a lifelong gluten-free diet. As selenium deficiencies in celiac disease are observed, the aim of the study was to determine the selenium content in 27 grain gluten-free products available on the European Union (EU) market. Moreover, selenium content in products based on popular gluten-free cereals like corn, rice, and buckwheat and in relatively new or less popular products based on oat, amaranth, teff, and quinoa was compared. Selenium content in the tested products ranged from 0.9 to 24.5 μg/100 g. The average content of selenium in products based on popular gluten-free cereals was 2.8 μg/100 g and in products based on oat, amaranth, teff, and quinoa was 10.8 μg/100 g. It indicates that products based on less popular grains, especially on oat, should be more frequently chosen as a source of selenium by people on gluten-free diet than traditionally consumed gluten-free grains.
