Our unique Immune Score is calculated based on key lifestyle categories that help build your immunity. These categories include Nutrition, Sleep, Activity and Lifestyle. 

Ways to increase your Immune Score:

    • Get outside for some exercise to increase your Activity category
    • Try to stop smoking and decrease the number of alcoholic drinks consumed per day
    • Connect your FitBit or AppleHealth to automatically sync your Sleep and Activity!
