Like nature, your body has the natural ability to protect and heal itself; it happens through your immune system. Research shows a healthy immune system helps prevent most common illnesses. However, stress, poor diet, lack of sleep and even medications can reduce your immune system’s ability to work at its best.

In addition, the immune system’s effectiveness increases from birth until the teenage years, but then undergoes a subtle decline throughout the rest of your life. This decline leads to impairment in coping with infectious agents that can cause disease and illness.

How all-natural ImmunExtra® with Proligna® supports your immune system.

Stress, poor diet, lack of sleep, even medication can reduce your immune system's ability to work at its peak.

ImmunExtra® is an all natural supplement containing
Proligna®, a botanical extract derived from pine cones that optimizes your immune system.

ImmunExtra® is the only immune support complex containing patented Proligna®, an extract of pinecones that has been shown to enhance immune cell activity. The scientific name for Proligna® is Polyphenylpropenoid-Polysaccharide Complex or PPC. The chemical structure is complex and gives it the ability to scavenge free radicals and to act as a potent antioxidant.

The health benefits of pinecone extract were first documented in 500 A.D. by the Greeks. Since that time, the extract has been used in modern day Japan, where it has long been associated with an increase in health and longevity. In the U.S., there has been more than 20 years of positive human experience with this pinecone extract.

Proligna® is made from young, 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.
