YTE Young Tissue Extract is a novel patented protein extract from fertilized chicken eggs harvested at a critical stage of incubation. Avian eggs contain all of the nutrients required to grow a developing embryo, including vitamins, minerals and proteins, as well as important defense factors, growth factors, hormones and other biologically active components.Fertilization causes changes to occur within the egg, including production of new proteins and other factors. Chromatographical analysis reveals a marked increase in high molecular weight molecules in fertilized eggs that are incubated to the peak date at which YTE is harvested when compared to eggs that are harvested even three days earlier. YTE contains a combination of beneficial amino acids and glycoproteins. Clinical studies suggest that this unique extract may have the ability to promote healthfulness and youthfulness. Studies have shown that the product enhances energy, vitality and stamina.
