Wellness

A cup of diced raw rhubarb has about 26 calories, 36 mcg of vitamin K (30% DV) and 9.8 mg of vitamin C (11% DV). That makes it a good source of vitamin C. (USDA) The NIH Office of Dietary Supplements says vitamin K is important for blood clotting and healthy bones. (NIH ODS) NIH ODS also says the body needs vitamin C to make collagen, which helps wounds heal, and that vitamin C improves absorption of iron from plant foods and helps the immune system work properly. (NIH ODS)
