Does Orange Juice Have Vitamin K? The Truth Revealed
Yes, orange juice contains small amounts of vitamin K, contributing to overall nutrient intake, but it’s not a significant source compared to other foods.
Many people wonder if orange juice contains vitamin K, especially those on blood thinners or looking to boost their nutrient intake. The short answer is yes, but only in trace amounts. Orange juice is not a significant source of vitamin K compared to leafy greens and other vegetables.
Vitamin K Content in Orange Juice
Orange juice contains minimal amounts of vitamin K. According to medical sources, citrus fruits like oranges fall into the “LOW vitamin K foods” category, containing less than 10 micrograms per serving. A typical 1-cup (240ml) serving of orange juice provides only trace amounts of this essential nutrient.
For comparison:
| Food | Vitamin K Content |
|---|---|
| Kale (1 cup cooked) | 1062 mcg |
| Spinach (1 cup raw) | 145 mcg |
| Orange juice (1 cup) | Trace amounts |
Why Vitamin K Matters
Vitamin K plays a crucial role in blood clotting and bone health. There are two main forms:
- Vitamin K1 (phylloquinone) – Found in plant foods
- Vitamin K2 (menaquinone) – Produced by gut bacteria and found in animal products
For those taking blood thinners like warfarin, maintaining consistent vitamin K intake is important. However, the small amount in orange juice is unlikely to affect medication effectiveness.
Nutritional Benefits of Orange Juice
While low in vitamin K, orange juice offers other valuable nutrients:
Vitamin C Powerhouse
One cup of orange juice provides over 100% of your daily vitamin C needs. This antioxidant supports immune function and collagen production. If you’re looking for more vitamin C options, check out our guide to the best juicer for apples, another excellent source of this vital nutrient.

- Folate – Important for cell growth
- Thiamine – Helps convert food to energy
Vitamin K-Rich Alternatives
If you’re specifically looking to increase your vitamin K intake, consider these foods:
Leafy Greens
Kale, spinach, and collard greens are among the richest sources. For easy incorporation into your diet, a quality juicer for leafy greens can help you create nutrient-packed drinks.
Other Good Sources
These foods provide moderate amounts of vitamin K:
- Broccoli
- Brussels sprouts
- Cabbage
- Blueberries
According to research from Healthline, while fruit juices like orange juice have benefits, vegetable juices often provide more nutrients with less sugar.
Special Considerations
For Those on Blood Thinners
If you take anticoagulant medications, the key is consistency. As noted by St. Jude Children’s Research Hospital, you don’t need to avoid vitamin K foods, but should maintain steady intake levels.
Storage and Preparation
Vitamin K is relatively stable, but some tips can help preserve nutrients:
- Store orange juice properly to maintain freshness
- Consume fresh-squeezed juice within a few days
- Consider whole oranges for added fiber
While orange juice isn’t a significant source of vitamin K, it remains a popular beverage with other nutritional benefits. For those specifically seeking vitamin K, incorporating leafy greens and other vegetables into your diet is the better approach.
