Kal Transfer Factor is a nutritional supplement that helps stimulate the body's natural defenses globally. Transfer Factors are universally effective, despite the differences between the donor and recipient species, that is, even if the origin is another species of mammal, they have an effect at the human level. Transfer Factor is effective when taken orally and has proven useful at all ages, from childhood to old age. Children especially benefit from this product because, unlike antibodies, transfer factors are very small, which helps make them non-allergenic. They are messenger molecules that educate and alert inexperienced cells about potential danger. It is recommended to take two vegetable capsules a day, preferably on an empty stomach, with a glass of water (150 ml).
