Give your immune system the boost it needs with EZC Pak Five-Day Immune System Booster. EZC Pak combines the immune boosting benefits of Echinacea, Vitamin C and Zinc supplement capsules into one easy to use Five-Day pack.

It is clinically formulated to deliver optimal immune support over a 5-day tapered course. Echinacea has long been used for immune support by promoting T-cell activity. Zinc is considered to be involved in virtually every aspect of immune health and function and Vitamin C is critical to the immune system's function and a wide range of metabolic reactions and is often depleted during illness. EZC Pak combines these essential vitamin, mineral & herbal supplements together into one powerful immune supplement: a 5-day immune booster that works when you need it.(1) These statements have not been evaluated by the Food and Drug Administration.
