The juice of celery, the light green and crunchy vegetable, is a nutritious food. Low in calories, celery juice contains only modest amounts of carbohydrates and proteins, few fats and no cholesterol. The juice is also filled with many essential minerals and vitamins, particularly vitamin K. This raises a health concern for those taking certain medications, with which vitamin K may interact.
Components
A 1-cup serving of celery juice weighs around 236 g. It contains around 9.5 g of carbohydrates, 2 g of proteins and less than 0.5 g of fats with minimal saturated fats and no cholesterol. The drink contains around 4 g of dietary fiber with the remaining portion consisting of other nutrients and water.
Calories
A 1-cup serving of celery juice contains around 50 total calories. Carbohydrates contribute 38 calories within the serving. Proteins provide eight calories and fats deliver just four calories per serving. The same amount of celery juice can serve as just 2.5 percent of the recommended daily caloric intake, based on a typical 2,000 calorie-per-day diet.
Vitamins
A serving of celery juice also provides significant amounts of many essential vitamins. The highest levels are from vitamin K at 89 mcg or almost 90 percent of the recommended daily intake, vitamin C at 14 mg or 17.5 percent, and vitamin B6 at 0.2 mg or over 13 percent of the RDI. Other less substantial amounts of vitamins in the serving include vitamins A, E, K, thiamine, riboflavin, niacin and folate.
Minerals
Celery juice also provides several important dietary minerals. These include potassium at 670 mg or 14 percent of the RDI, calcium at 99 mg, and iron at 0.99 mg or nearly 10 percent for each mineral. Other minerals, such as magnesium, phosphorus, selenium and zinc are also found within a serving.
Health Concerns
Celery juice is particularly high in vitamin K, which is directly involved in the proper clotting of blood in the body. Though an important factor in the healing process, high vitamin K levels in the diet may interfere with the function of certain medications, specifically, blood-thinning agents such as warfarin. People taking blood-thinning medications should avoid celery juice in the diet.
