The Surprising Lack of Vitamin K in Fresh Dill
While dill is a vibrant green herb known for its distinct flavor, official nutritional data confirms that it is not a source of vitamin K. Most nutritional databases, including those sourced from the USDA, list the vitamin K content of fresh dill as 0 micrograms (mcg) per standard serving. This is in stark contrast to many other green leafy vegetables and herbs, which are prized for their high vitamin K content. This absence of vitamin K is consistent across fresh and dried versions of the herb itself, according to reputable sources.
The reason for this can be attributed to the specific phytochemical and micronutrient makeup of the dill plant. Instead of accumulating phylloquinone, the plant-based form of vitamin K, dill synthesizes and stores other nutrients, most notably powerful antioxidants and a high concentration of vitamin A and C. Therefore, adding fresh dill to a meal should not be considered a way to boost your daily intake of this specific vitamin.
Comparing Dill with High-Vitamin K Herbs
To understand just how unique dill's nutritional profile is, consider its low vitamin K content compared to herbs often used in similar culinary applications. Here is a brief look at how dill stacks up against other herbs in terms of vitamin K:
- Dill (Fresh): Offers 0 mcg of vitamin K per serving.
- Parsley (Fresh): A single cup can provide nearly 1,000 mcg of vitamin K, highlighting a massive difference in nutrient composition.
- Spinach (Raw): This leafy green is a well-known source of vitamin K, with one cup providing well over 100% of the daily value.
- Basil (Fresh): A single ounce can supply 145% of the Daily Value for vitamin K.
What Fresh Dill Does Offer: A Rich Nutrient Profile
Despite its lack of vitamin K, fresh dill is far from nutritionally void. It is a source of several other important vitamins and minerals that offer valuable health benefits. Its low-calorie, high-antioxidant makeup makes it a great addition to many meals.
- Vitamin C: Fresh dill provides a notable amount of vitamin C, an antioxidant crucial for immune system function and wound healing.
- Vitamin A: It also contains a significant amount of vitamin A, which supports vision, immune health, and healthy skin.
- Manganese: As an essential mineral, manganese supports the normal functioning of your brain and nervous system.
- Other Minerals: The herb also contributes small but useful amounts of potassium, calcium, magnesium, and iron.
- Antioxidants: Dill contains a range of antioxidant compounds that help protect cells from damage caused by free radicals.
Nutritional Comparison: Fresh Dill vs. Other Green Herbs
| Nutrient | Fresh Dill (per 100g) | Fresh Parsley (per 100g) | Raw Spinach (per 100g) |
|---|---|---|---|
| Vitamin K (mcg) | 0 | ~1,640 | ~483 |
| Vitamin C (mg) | 85 | ~133 | ~28 |
| Vitamin A (mcg) | 386 | ~421 | ~469 |
| Calcium (mg) | 208 | ~138 | ~99 |
| Manganese (mg) | 1.3 | ~1.6 | ~0.9 |
The Vitamin K in Dill Pickles: A Common Misconception
Some confusion regarding dill's vitamin K content likely stems from its association with dill pickles. A single dill pickle can indeed contain a percentage of the daily recommended amount of vitamin K, with some sources citing up to 20%. However, this vitamin K comes from the cucumber itself and other spices used in the brining process—not from the dill weed or seed added for flavor. The pickling process does not infuse vitamin K into the dill. It is important to distinguish between the nutritional content of the herb and the fermented product it flavors.
The Importance of Vitamin K for Overall Health
For those seeking dietary sources of vitamin K, it is worth understanding why this nutrient is so important. Vitamin K plays a crucial role in the body, primarily in two key areas:
- Blood Clotting: The body requires vitamin K to produce prothrombin and other proteins essential for blood coagulation. This function is vital for stopping bleeding and allowing wounds to heal.
- Bone Health: Vitamin K is also necessary for building and maintaining healthy bone tissue. It helps the body produce osteocalcin, a protein that requires vitamin K to function correctly. Some research suggests higher vitamin K intake is associated with stronger bone density and a lower risk of fractures.

Conclusion
In summary, fresh dill contains virtually no vitamin K, a notable exception among many green herbs. Its nutritional value lies in its high content of vitamins A and C, antioxidants, and a pleasant boost of minerals like manganese, calcium, and potassium. While dill pickles can be a source of vitamin K, this is derived from the cucumber, not the dill. For those specifically looking to increase their vitamin K intake, other herbs like parsley or leafy greens such as spinach are much more effective choices. Dill remains a healthy, flavorful addition to a balanced diet for its other beneficial nutrients.
