Quality & Science
Proligna® is made from fresh, clean pinecones harvested from Wisconsin forests. A patented method extracts the desirable molecules; the liquid extract is then tested extensively to ensure it is contaminant-free. It is gently dried to a powder that is used to make vegetarian ImmunExtra® capsules.
Allera Health Products believes that quality ingredients and strict control of manufacturing and packaging are essential to product quality and efficacy. Immunextra® is packaged in National Sanitation Foundation certified facilities that employ FDA Good Manufacturing Practices. 30 peer reviewed scientific publications describe the research performed on PPC.
