IgYssentiel®: Polyclonal Immunoglobulin Y (IgY), a breakthrough natural solution to strengthen immunity
Exclusive active ingredient from THERASCIENCE Laboratory, IgYssentiel® polyclonal immunoglobulins (IgY) are an unprecedented innovation in Physionutrition. IgYs are antibodies naturally produced by hens and transferred to egg yolks to protect chicks after hatching. They are specific biological proteins, whose role is similar to that of human IgG, and have long been studied in immunology.
Of natural origin and derived from egg yolks, IgYssentiel® is produced using a unique process that guarantees exceptional purity of 99%, 500 times higher than other IgY products available on the market. Our IgYs are stable, non-toxic and resistant to pancreatic enzymes. In addition, IgYssentiel® is packaged in 100% vegetable gastro-resistant capsules, ensuring maximum efficacy.
Efficiency of IgYssentiel®
Immunoglobulin Y (IgY) has been the subject of numerous scientific publications. Its structure and biochemical characteristics have been extensively described in international scientific literature, particularly in the fields of immunology and life sciences.
IgYssentiel®was the subject of a randomised clinical trial conducted on 28 healthy patients in a double-blind, placebo-controlled study, supplemented with polyclonal Y immunoglobulins for 3 months(1).
Thanks to its unique mechanism of action, broad spectrum of activity and excellent safety profile, IgYssentiel® is a new, cutting-edge approach to physionutrition.Thanks to its unique mechanism of action, broad spectrum of activity and excellent safety profile, IgYssentiel® is a new, cutting-edge approach to physionutrition.
