Immune System
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.


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, vegetarian, clinically-tested supplement containing
Proligna®, a botanical extract derived from pine cones that optimizes your immune system.


ImmunExtra® is the only immune product containing patented Proligna®, a natural water extract of pinecones that has been shown to enhance the production of human dendritic cells 9 fold in 9 days. More recently, laboratory research has shown that Immunextra reduces the Th2 arm of the immune system while at the same time promoting the Th1 arm of the immune system.

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. Try it to stay healthy.  It is one of the only supplements tested to be safe in human studies at three independent medical centers in the United States.
