Orange juice contains very little vitamin K. A typical 1-cup serving provides about 0.2 micrograms, according to common food composition data. That amount contributes less than 1% of the daily adult target.
So, orange juice doesn’t count as a meaningful vitamin K source. It still supplies vitamin C, folate, and potassium, which explains why it can fit a balanced diet.

Why orange juice contains so little vitamin K
Vitamin K occurs mainly in leafy green vegetables, some vegetable oils, and certain fermented foods. Oranges contain only small traces, so their juice starts with little vitamin K.
Vitamin K also dissolves in fat. Orange juice contains almost no fat, but fat content alone doesn’t explain the low number. The orange itself simply isn’t rich in this vitamin.
Fresh juice and regular packaged juice usually provide similarly small amounts. Processing can change some nutrients, yet it doesn’t turn orange juice into a vitamin K-rich food.
How much vitamin K does a glass provide?
| Food or serving | Approximate vitamin K | What it means |
|---|---|---|
| Orange juice, 1 cup | About 0.2 mcg | Negligible source |
| Raw spinach, 1 cup | About 145 mcg | Rich source |
| Raw kale, 1 cup | About 113 mcg | Rich source |
| Broccoli, 1 cup chopped | About 90 mcg | Useful source |
Food values vary with the serving size, crop, and preparation. Fortified products can differ more, so check the Nutrition Facts panel when a carton claims added vitamins.
What vitamin K does in the body
Vitamin K helps activate proteins involved in normal blood clotting. It also helps proteins manage calcium in bone and other tissues.
Adults generally need about 90 micrograms daily for women and 120 micrograms for men. These figures are adequate intake values, not a target orange juice needs to meet.
One glass cannot supply much vitamin K. A serving of leafy greens can cover most or all of an adult’s daily amount.
Does vitamin K in orange juice change with processing?
Standard pasteurization doesn’t make orange juice a significant vitamin K source. The starting vitamin K content remains very low.
Some products add calcium, vitamin D, or other nutrients. Those additions don’t automatically include vitamin K. Read the label instead of assuming fortified juice contains every common vitamin.
Shelf-stable, refrigerated, fresh, and frozen products may show different nutrient panels. The label for your specific carton gives the most useful answer.
Orange juice has other useful nutrients
Orange juice is better known for vitamin C than vitamin K. It can also provide folate and potassium, though the amount depends on the serving and product.
For details on its potassium content, see this guide to orange juice potassium. Calcium-fortified cartons receive separate treatment in this orange juice calcium guide.
Juice also lacks the fiber found in a whole orange. Many products contain natural sugar, while some contain added sugar. This orange juice added sugar guide explains how to read that distinction.
Can orange juice replace a vitamin K supplement?
No. Its vitamin K content is too small for that purpose. A supplement also delivers a concentrated dose, while orange juice contributes only a trace.
Life Extension Super K lists 2,000 micrograms of vitamin K and 1,180 micrograms of vitamin K2 per serving. Its formula includes vitamin K1 and two K2 forms, according to the product information.
The product information also describes support for heart and arterial health and calcium balance. Those statements describe the supplement’s intended role. They don’t mean every person needs a high-dose vitamin K product.
Diet usually supplies vitamin K through vegetables and oils. A supplement may suit a person whose clinician identified a need, but the dose deserves careful review.
Vitamin K and blood-thinning medication
People who take warfarin need consistent vitamin K intake. Sudden changes can affect how the medication works.
Orange juice contributes almost no vitamin K, so it rarely drives this issue. A concentrated supplement can matter much more because its dose greatly exceeds a glass of juice.
Ask the prescribing clinician before starting, stopping, or changing a vitamin K supplement. Don’t alter prescribed medication based on a food article.
Questions readers often ask
Does fresh orange juice have more vitamin K than packaged juice?
Usually, no meaningful difference exists. Both forms generally contain only trace amounts. A fortified package can differ, so inspect its label.
Can drinking orange juice cause a vitamin K overdose?
Orange juice alone is very unlikely to cause excess vitamin K intake. Its vitamin K content is minimal.
Supplement doses need more care. Medication use, health conditions, and the product formula all matter.
Does pulp change the vitamin K content?
Pulp may add a little fiber and plant material, but it doesn’t make orange juice a rich vitamin K source. The difference remains small for normal servings.
Is vitamin K1 or K2 present in orange juice?
Orange juice may contain tiny amounts of vitamin K1. It isn’t a dependable source of K1 or K2.
K1 dominates leafy greens. K2 occurs in some fermented foods and animal products.
Should I drink orange juice for vitamin K?
No. Drink it for its taste and nutrients such as vitamin C, not for vitamin K.
Choose leafy greens, selected vegetables, or another suitable food when vitamin K intake matters. A clinician can assess whether a supplement makes sense.
The practical answer
Orange juice has vitamin K only in trace amounts. One cup provides roughly 0.2 micrograms, so it makes almost no difference to daily vitamin K intake.
Check the carton if it lists added nutrients. Treat concentrated vitamin K supplements as a separate decision, especially when warfarin or another medication is involved.
Orange Juice Contains Vitamin C
Orange juice is well known for its vitamin C content. A typical 8 oz (1 cup) serving provides about 90 to 120 milligrams of vitamin C, covering most or all of the daily recommended amount for adults. This vitamin supports immune function, skin health, and antioxidant protection.
Unlike vitamin K, vitamin C is water-soluble and abundant in oranges, making orange juice a reliable source. However, vitamin C levels can vary slightly depending on processing and storage, but fresh and packaged juices generally remain good sources.
