I adore Four Sigma Foods products! The instant drinks are game changing. I carry the packets in my purse for when I am on the go. I also add them to soups after they have been cooked and smoothies for an extra nutritional boost. The powders dissolve quickly and have a smooth taste. I love having an immune booster with me at all times and I even sneak them into drinks for my young daughter. NaturallyLauren.com.
