Glandular tissues can be rich sources of nutrients, enzymes and other factors that support specific gland-related metabolism and physiological function. When prepared with sufficient technical sophistication and sensitivity to their delicate nature, glandulars can retain a significant portion of their biological activity. NutriCology? glandular products are produced from government inspected, range-grazed animals raised in New Zealand without the use of pesticides, hormones and antibiotics. Our glandulars are lyophilized (freeze?dried), which means the material is frozen, then subjected to a high vacuum that vaporizes moisture directly from the solid state, thereby maintaining their biological activity. They are highly potent and are generally well tolerated.
