To balance out my sugar and coffee intake I tried a Vive Organic Immunity Boost.
I've had similar "boosts", just different brands. I've never been able to do shots very well, so drinking this in four sips attests to it's terrific flavor and drinkability. I bought one for a friend as well and she downed it as a shot; even with the turmeric and pepper it went down smoothly.
What's your trick to boosting your immunity?
