The EZC Active Pak is an award-winning physician-formulated immune support pack designed to support healthy immune system function of individuals with active on-the-go lifestyles. The Active Pak is an excellent choice during travel, times of peak stress, or lack of sleep when immune system function is often at its weakest. Suggested use is twice a day for maintenance immune support and up to four times a day for maximal immune support. The EZC Active Pak can also be used to bridge to the EZC 5-Day Tapered Immune Support Pak when extended immune support becomes necessary.
