When nutritionists consider the dosing of vitamins and minerals, one of their key areas of focus is the rate at which nutrients are used up (i.e. metabolized) and need to be replenished. In a similar way, Nu Skin scientists wanted an understanding of the kinetics (i.e. the absorption, metabolism, and clearance) of ageLOC Youth’s ingredients. Because the gene expression effects of ageLOC Youth’s ingredients require first, that the ingredients are delivered through the bloodstream to tissues and cells, Nu Skin scientists wanted to better understand how long ageLOC Youth’s polyphenol components remain in the body. Polyphenols are a class of water soluble plant, or fruit extracts, which tend to pass through the body faster than many of ageLOC Youth’s other nutrients.
ageLOC Youth’s polyphenols include:
• Anthocyanins (from purple corn extract)
• Resveratrol (dietary sources include red wine)
• Hesperidin, and naringin (from citrus peels)
• Quercetin (rich dietary sources include onions)
An understanding of the absorption and clearance rates of these most-rapidly-metabolized compounds would enable Nu Skin scientists to better assess the exposure of organs, tissues, and cells.
