You can absolutely drink cabbage on a daily basis if you want to top up your levels of vitamins and improve your gut health.
Cabbage is high in antioxidants, and has anti-inflammatory properties, but it can cause stomach upset so bear this in mind.
You can drink anywhere from 4 to 8 ounces of cabbage juice at a time, so a glass first thing in the morning on a regular basis can be beneficial for your overall health.
