The Surprising Vitamin Profile of a Small Bud
Capers, the unripened flower buds of the Capparis spinosa plant, are a staple of Mediterranean cuisine known for their distinctively pungent, salty, and tangy flavor. While they are consumed in small quantities as a garnish or seasoning, they provide a surprising punch of important vitamins and other beneficial compounds. A 100-gram serving, while high in sodium, gives a clear picture of their vitamin density.
Vitamin K: Crucial for Blood and Bone Health
When asking what vitamins are capers high in, Vitamin K is the most prominent answer. A 100-gram portion of canned capers offers a significant percentage of the daily recommended intake for this vital nutrient. Vitamin K plays an essential role in the body's natural blood clotting processes and is also crucial for maintaining strong, healthy bones. For those looking to increase their dietary intake of this fat-soluble vitamin, capers are a flavorful and easy way to do so.
B-Vitamins: Fueling Your Body's Energy
Beyond Vitamin K, capers contain a healthy dose of B-vitamins, particularly riboflavin (B2) and niacin (B3). Riboflavin helps the body convert food into fuel, ensuring that you stay energized throughout the day. Niacin also aids in energy production and supports overall nervous and digestive system health. While the amount in a single tablespoon is small, it contributes to your overall intake of these essential compounds. Capers also contain smaller quantities of Folate (B9) and Thiamin (B1), further rounding out their B-vitamin contributions.
Antioxidant Vitamins: A, C, and E
Capers also contain smaller, but still beneficial, amounts of antioxidant vitamins like Vitamin A, Vitamin C, and Vitamin E. Vitamin A is well-known for its role in supporting vision and immune function, while Vitamin E provides antioxidant protection for cells. The presence of these vitamins, along with potent flavonoids, solidifies the caper's reputation as a healthy and nutrient-dense food choice.
More Than Just Vitamins: Other Key Nutrients in Capers
While vitamins are a key part of the caper's nutritional profile, it is also important to consider its other components.
High Sodium Content
Due to the brining or salting process used to preserve capers, they have a very high sodium content. A 100-gram serving can easily exceed the recommended daily value for sodium, which is why capers should always be consumed in moderation. For those watching their sodium intake, rinsing the capers before use can help to wash away some of the excess salt.
Mineral Support
In addition to vitamins, capers offer a range of essential minerals, including copper, iron, manganese, calcium, and magnesium. These minerals play various roles, from supporting energy production and bone health to aiding in blood circulation and muscle function.
Powerful Flavonoid Antioxidants
Capers are rich in powerful antioxidant flavonoids, such as quercetin and rutin. Quercetin has anti-inflammatory and antibacterial properties, while rutin helps strengthen capillaries and improve blood circulation. These compounds are believed to be the source of many of the health benefits associated with capers.
Comparison: Capers vs. Other Brined Foods
To put the nutritional content of capers into perspective, here is a comparison with other common brined foods per 100g serving.
| Nutrient | Capers (Canned) | Olives (Green, Pitted) | Pickles (Dill, Kosher) |
|---|---|---|---|
| Vitamin K | 24.6 µg (21% DV) | 1.4 µg (1% DV) | 39.8 µg (33% DV) |
| Riboflavin (B2) | 0.14 mg (11% DV) | 0.0 mg (0% DV) | 0.05 mg (4% DV) |
| Niacin (B3) | 0.65 mg (4% DV) | 0.2 mg (1% DV) | 0.23 mg (1% DV) |
| Sodium | 2350 mg (102% DV) | 1556 mg (68% DV) | 1208 mg (52% DV) |
Note: Nutritional values can vary based on processing and specific brand. Source data for olives and pickles is based on general USDA data.
As the table shows, capers offer a good amount of vitamin K and a respectable amount of riboflavin compared to some other popular brined items. Their exceptionally high sodium content, however, is the most important factor for consumers to be aware of.
How to Incorporate Capers into Your Diet
There are many ways to add the unique flavor and nutritional benefits of capers to your meals, while managing the sodium levels. Rinsing the capers thoroughly under cold water is the most effective way to reduce their saltiness.
Here are some ideas for using capers:
- Sauces and Dressings: Add rinsed capers to a lemon-butter sauce for fish, or include them in a tangy vinaigrette for salads.
- Salads: Sprinkle capers over a Greek or Caesar salad for a burst of salty flavor. They pair especially well with fresh greens, tomatoes, and cucumber.
- Fish Dishes: Use capers as a garnish for smoked salmon or as an ingredient in a classic piccata sauce for chicken or veal.
- Pasta Dishes: Stir them into pasta sauces, such as spaghetti alla puttanesca, for a briny depth of flavor.
- Appetizers: Mix finely chopped capers with cream cheese for a flavorful spread or include them in an olive tapenade.

Conclusion
In summary, for those asking "what vitamins are capers high in?", the primary answer is Vitamin K, with a good contribution of Riboflavin and other B-vitamins. They also contain valuable antioxidants like quercetin and beneficial minerals. While capers are an excellent source of flavor and nutrients, their high sodium content is a key consideration that necessitates moderation and mindful preparation, such as rinsing. By being aware of these factors, you can enjoy the distinctive taste and health benefits of capers as part of a balanced diet.
A Final Word on Moderation
Despite their nutritional benefits, the high sodium levels in capers mean they should be used as a flavorful condiment rather than a primary food source. Incorporating them judiciously can enhance your dishes without negatively impacting your sodium intake. Consider using smaller, non-pareil capers for more concentrated flavor, allowing you to use less.
