Gut Boosters are the “pickle juice” from the krauts. They are made from organic vegetables fermented in salt brine. They can be consumed as a “shot” to quickly deliver probiotics to one’s system, or added to a smoothie to make it probiotic. Recommended serving is 2 oz daily. They are still living, so should be kept refrigerated at all times to prevent further buildup of carbonation through microbial activity.
