All similar products are required to use the same serving size so a consumer can compare. For sauerkraut, the serving size is set by the FDA at 2 tablespoons. As far as nutritional benefit, it differs for everyone. Here are some recommendations from some authorities: “According to personal clinical experience, regular intake of small doses of sauerkraut—7 g to 10 g (or about 1 T) daily—has a very good effect on many patients’ gastrointestinal tract.” from the National Center for Biotechnical Information “Little and often is better than consuming a large amount of fermented food once a week because you need to keep energizing the microbes in your gut,” according to Tim Spector, Professor of Genetic Epidemiology at King’s College London, and author of The Diet Myth: The Real Science Behind What We Eat. We recommend you start one or two servings of fermented products in the beginning, and see how your body reacts. It will naturally adjust to the addition of good bacteria. Then, you can add a little more each day to see how your body reacts (remember those probiotics are live and active) until you find the right balance. Also, if you have an immune-related illness, please check with your healthcare practitioner before making any changes to your diet.
