Pumpkin seeds may be small, but they pack a big nutritional punch. Rich in protein, healthy fats, fiber, and key minerals like magnesium and zinc, they’ve earned a spot on the list of foods worth keeping in your pantry. Snackable, crunchy, and endlessly adaptable, pepitas, as pumpkin seeds are often called, are an easy way to sneak extra nutrients into your day. We spoke with nutrition experts to learn all about the benefits of pumpkin seeds and the best ways to enjoy them.

Support Heart Health

Pumpkin seeds are rich in fiber and unsaturated fats, both of which promote heart health. "The magnesium, potassium, and unsaturated fats in pumpkin seeds help regulate blood pressure, reduce inflammation, and support healthy cholesterol levels, which are all key for heart health," says Lorenz.

Our experts say a good serving size is a small handful of pumpkin seeds, about 1 ounce (¼ cup). That amount provides roughly 150 calories, 7 grams of protein, plus a generous helping of magnesium, zinc, and healthy fats.

Help Keep Blood Sugar Steady

With their mix of protein, fiber, and healthy fats, pumpkin seeds can slow digestion and blunt post-meal blood sugar spikes. Lorenz notes that magnesium also plays a role in improving insulin sensitivity, which further supports stable blood sugar levels.

Provide Plant-Based Protein

At about 7 grams of protein per ounce, pumpkin seeds are a satisfying plant-based option for vegetarians, vegans, or anyone looking to add more protein to their snacks and meals, says Tolentino.

Promote Better Sleep and Mood

Pumpkin seeds contain tryptophan, an amino acid that supports serotonin and melatonin production. Paired with magnesium, this combo has been linked to relaxation, a steadier mood, and potentially better sleep, says Tolentino, though the research isn't yet definitive.

Deliver Antioxidant and Anti-Inflammatory Benefits

These little seeds are a source of vitamin E, zinc, magnesium, and polyphenols—all of which have antioxidant or anti-inflammatory effects. Together, they "act as antioxidants to protect cells from damage and help lower inflammation in the body," explains Lorenz.

Support Immune Function

Thanks to their zinc and magnesium content, pumpkin seeds help strengthen the immune system. These minerals play a role in immune cell function and defense against illness.

Offer Versatility in the Kitchen

Beyond their nutrient profile, our experts point out that pumpkin seeds are easy to work into your daily routine. They’re equally good raw or roasted, on their own, or as an add-in. They can lean sweet or savory, and you can incorporate them into breakfast, lunch, dinner, or snacks.

Sprinkle them over salads, oatmeal, or yogurt, blend them in smoothies, toss over roasted vegetables, mix into pasta or grain bowls, or simply enjoy by the handful as a quick snack.

Are Raw or Cooked Pumpkin Seeds Better?

Pumpkin seeds can be eaten both raw and roasted—and the great news is that both deliver benefits, though raw seeds retain slightly more antioxidants and heat-sensitive nutrients. "Overall, the loss is minimal, and roasted seeds are still a healthy food choice," says Tolentino. Lorenz agrees, saying it's still certainly worthwhile to buy roasted pumpkin seeds, especially if you prefer them more than raw.
