Your 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.

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.
