The Primary Vitamins in Pumpkin Seeds
Pumpkin seeds, or pepitas, are often celebrated for their mineral content, but their vitamin profile is just as impressive. These small, powerful seeds offer a handful of key vitamins that support various bodily processes, from cellular protection to metabolic functions. The most notable vitamins found in pumpkin seeds are Vitamin K and Vitamin E.
Vitamin K: Essential for Blood and Bones
One of the standout vitamins in pumpkin seeds is Vitamin K. This fat-soluble vitamin plays a crucial role in several physiological functions. Primarily, it is essential for the process of blood clotting, helping to form the clots that stop bleeding after an injury. Beyond this, Vitamin K also contributes to bone metabolism, ensuring that calcium is effectively directed to the bones, which is vital for maintaining strong, healthy bone tissue. Some evidence suggests that raw pumpkin seeds may contain slightly more vitamin K than their roasted counterparts. Given that many people do not consume adequate Vitamin K, adding a handful of pumpkin seeds to your diet is an easy way to increase your intake.
Vitamin E: A Powerful Antioxidant
Pumpkin seeds are also a good source of Vitamin E, a potent fat-soluble antioxidant. This vitamin is crucial for protecting the body's cells from oxidative damage caused by harmful free radicals. Oxidative stress can contribute to chronic diseases and premature aging, so a high intake of antioxidants is beneficial for long-term health. Vitamin E in pumpkin seeds also helps to strengthen the immune system and maintain the integrity of healthy blood vessels, contributing to overall cardiovascular health. The combination of Vitamin E and other antioxidants in pumpkin seeds is partly responsible for their overall anti-inflammatory effects.
Other Significant Vitamins and Nutrients
The B-Vitamin Complex: A Source of Energy
In addition to the fat-soluble vitamins, pumpkin seeds also provide a range of important B-vitamins. These include Thiamine (B1), Riboflavin (B2), Niacin (B3), Pantothenic acid (B5), and Folate (B9). This B-vitamin complex is essential for energy metabolism, helping the body convert food into energy. Folate, in particular, is critical for cell growth and the formation of DNA, making it especially important for women during pregnancy.
The Critical Role of Minerals
While this article focuses on vitamins, it is impossible to discuss the full nutritional impact of pumpkin seeds without acknowledging their dense mineral content. Minerals like zinc and magnesium work synergistically with the vitamins to provide comprehensive health benefits. Magnesium is crucial for nerve and muscle function, bone health, and regulating blood pressure and blood sugar. Zinc is vital for a strong immune system, wound healing, and reproductive health. The vitamins in pumpkin seeds enhance the benefits provided by these minerals, creating a powerful nutritional profile.

Pumpkin Seeds vs. Other Common Seeds
While pumpkin seeds are highly nutritious, it's helpful to see how their vitamin profile compares to other popular seeds, like sunflower seeds. Here is a simple comparison based on a typical 1-ounce (28g) serving of hulled seeds.
| Nutrient | Pumpkin Seeds (Approx.) | Sunflower Seeds (Approx.) | Notes |
|---|---|---|---|
| Vitamin K | 7.3 mcg (6% DV) | < 1 mcg | Pumpkin seeds are a superior source of Vitamin K. |
| Vitamin E | 2.2 mg (15% DV) | 7.4 mg (49% DV) | Sunflower seeds are a significantly richer source of Vitamin E. |
| Thiamine (B1) | 0.3 mg (23% DV) | 0.4 mg (35% DV) | Both are excellent sources, with sunflower seeds having slightly more. |
| Folate (B9) | 57 mcg (14% DV) | 67 mcg (17% DV) | Both seeds offer a moderate amount of folate. |
| Zinc | 2.2 mg (20% DV) | 1.5 mg (14% DV) | Pumpkin seeds offer a higher concentration of zinc. |
| Magnesium | 156 mg (37% DV) | 36 mg (9% DV) | Pumpkin seeds are a far superior source of magnesium. |
This comparison highlights that while sunflower seeds are higher in Vitamin E, pumpkin seeds stand out for their Vitamin K content and offer a better balance of zinc and magnesium.
