Mildly spicy with a strong vegetal taste, red cabbage is associated more with soup and coleslaw than with juice. However, this nutrient-packed vegetable can be juiced and added to other vegetable or fruit juices to increase the nutritional content. The U.S. Department of Agriculture recommends eating between 4 to 6 cups of red vegetables per week for adult men and women. It takes 3 cups of chopped fresh, red cabbage to produce a 1/2 cup of red cabbage juice.
Vitamin C helps with the production of collagen, including the production and repair of all tissues in your body. It also helps your body heal wounds, as well as repair and maintain bones and teeth. A natural antioxidant, vitamin C protects your body from free radicals and environmental toxins, which can cause cell damage and death. A 1/2-cup serving of red cabbage juice contains 152 milligrams of vitamin C per serving, which is more than 100 percent of the recommended daily intake for adults.
Potassium is an electrolyte and essential mineral that helps control the electrical activity in your heart.

Vitamin K is essential for helping your blood clot. This reduces the risk of abnormal bleeding and bruising. Vitamin K also helps with maintaining strong bones, reducing the risk of osteoporosis.

A 1/2-cup of red cabbage juice contains 48 micrograms of folate, which is 12 percent of the acceptable intake for adult men and women, and almost 10 percent of the AI for pregnant and breastfeeding women.
