Are pumpkin seeds good for you. Short answer, yes, pumpkin seeds are good for you (very good). Long answer incoming…one ounce of shelled pepitas delivers around 8 grams of protein, 37% of your daily magnesium, and meaningful amounts of iron and zinc, all in a small, conveniently portable handful. After you carve up your pumpkins this Halloween, save the seeds. And if you grow heirloom pumpkins, the seeds are just as worth keeping.

Pumpkin seeds in the shell are a good source of fiber, while pepitas (the hulled inner seed) are especially rich in protein, magnesium, and iron. Together, these nutrients support gut health, heart health, bone health, and more. This is one of those foods that earns a regular spot in your diet, not just a seasonal one.

Keep reading to learn more about the benefits of pumpkin seeds and how to enjoy raw pumpkin seeds and pepitas in a healthy, well-rounded diet.

Pumpkin Seeds vs. Pepitas: What’s the Difference?

Raw pumpkin seeds are the whitish-colored seeds you see when you dig out the flesh of your pumpkin before carving. Pepitas, on the other hand, are the green seeds beneath that whitish exterior. Pepitas can be eaten raw, while pumpkin seeds are better roasted. Both are simply different forms of the same seed, with different textures and flavors.

Pumpkin Seeds Nutrition

The seeds may be the most nutritious part of a pumpkin. Here’s how the nutrition compares between in-shell pumpkin seeds and hulled pepitas, both at a 1 oz (28g) roasted serving.12

Pumpkin Seeds Benefits: What the Research Supports

Here are the benefits most supported by the research, ordered from strongest evidence to more preliminary findings.

Magnesium

The benefits of pumpkin seeds include their nutrition and versatility. Adding pumpkin seeds to granola bars is a great source of fiber and iron.

Pumpkin seeds are one of the richest dietary sources of magnesium available. One ounce of hulled pepitas provides 156 mg, nearly 37% of the daily recommended intake for adult women and about 37% for adult men. Magnesium is involved in over 300 enzymatic reactions in the body and is crucial for muscle function, energy production, and bone health.3 Magnesium deficiency has been linked to decreased athletic performance4 and a higher risk of osteoporosis,5 so consistently meeting your magnesium needs matters.

Fiber and Protein

Pumpkin seeds are a good source of both fiber and plant-based protein. Dietary fiber supports gut health and has been associated with a lower risk of coronary heart disease, stroke, hypertension, type 2 diabetes, obesity, and certain gastrointestinal diseases. It also helps lower blood pressure and cholesterol levels, and for people with diabetes, it may improve insulin sensitivity.6 If you want the most fiber from your pumpkin seeds, eat them in the shell, one ounce provides over 5 grams.

On the protein side, one ounce of hulled pepitas delivers about 8.4 grams, a meaningful contribution for anyone building meals around plant-based protein sources.

Heart Health

The oils in pumpkin seeds have been studied for their anti-hypertensive and cardio-protective effects.7 Pumpkin seeds contain significant levels of poly- and mono-unsaturated fats, as well as sterols, that may support cardiovascular health. One study found that pumpkin seed oil improved blood pressure and cardiovascular outcomes in females.8

Iron and Zinc

Iron is found in every cell in the body and helps make the oxygen-carrying proteins hemoglobin and myoglobin, found in red blood cells and muscles respectively. Low iron levels can lead to anemia, fatigue, shortness of breath, headache, irritability, and dizziness.

One ounce of hulled pepitas provides about 2.3 mg of iron, around 13% of the RDA for adult women and 29% for adult men.9 The iron in pumpkin seeds is non-heme iron, which is less readily absorbed than heme iron from animal sources. Pairing pumpkin seeds with a source of vitamin C can support absorption.

Pumpkin Seeds Benefits for Female Health

Pumpkin seeds have a few specific points of interest for women. Their iron content can be especially helpful for vegetarians, vegans, and anyone with higher iron needs. On the cardiovascular side, research has found that pumpkin seed oil may help improve blood pressure and lipid profiles in women.8

There is also a small study suggesting that pumpkin seed oil may help manage some menopausal symptoms,10 though this research is preliminary and applies specifically to pumpkin seed oil as a supplement, not to eating the seeds themselves. The findings are worth watching as research develops.

Pumpkin Seeds and Men’s Health

Pumpkin seeds also show some promise for men’s health specifically. A 2022 study on pumpkin seed soft extract (PSE) in men with benign prostatic hyperplasia (enlarged prostate) found that PSE may help reduce symptoms, improve quality of life, and support sexual well-being.11

One small study (76 men, 24 weeks) also found that pumpkin seed oil capsules were associated with a 40 percent increase in mean hair count in men with mild to moderate androgenetic alopecia, compared to a 10 percent increase in the placebo group.12 This research applies specifically to pumpkin seed oil as a supplement, eating pumpkin seeds may not produce the same effect.

Sleep: Early and Indirect Evidence

Pumpkin seeds contain tryptophan, an amino acid that plays a role in the production of serotonin and melatonin. A 2022 study found that tryptophan supplementation at doses greater than one gram per day was associated with improved sleep quality.13 It’s worth noting that you’d need to eat an impractical amount of pumpkin seeds to reach that threshold from food alone, so the sleep connection remains indirect at normal serving sizes.

How Many Pumpkin Seeds Should You Eat a Day?

About one ounce (28 grams) per day is a practical portion. If you prefer hulled pepitas, that’s roughly ¼ cup. If you eat them in the shell, you’ll get a bit more volume for the same weight. Either way, one ounce is enough to contribute meaningfully to your daily magnesium, protein, and iron intake without overdoing it on calories.

If you’re eating them as a topping for salads or soups, a tablespoon or two adds texture and nutrition without overwhelming the dish. As a standalone snack, a small handful is plenty.

Can You Eat Pumpkin Seed Shells?

Yes. Pumpkin seed shells are edible and taste particularly good when roasted and seasoned. The outer husk adds fiber and some protein on top of what the inner seed already provides. If you’re carving a pumpkin and roasting the seeds yourself, there’s no need to hull them first.

Raw vs. Roasted (and Sprouted) Pumpkin Seeds

Roasted Pumpkin Seeds

To roast pumpkin seeds, start by cleaning and drying them thoroughly. Line a baking sheet with parchment paper and roast the seeds for 20 minutes at 325°F. Sprinkle with a bit of salt or your seasoning of choice before serving. Roasted pumpkin seeds are delicious on their own or as a topping for soups, salads, and grain bowls.

For a step-by-step guide, see our full article on how to roast pumpkin seeds to crispy perfection.

Roasted pumpkin seeds are nutritionally similar to raw. Just watch for added salt, oil, or sugar coatings in pre-packaged options.

Soaking Raw Pumpkin Seeds

Soaking is not required before roasting, but some people choose to do it for two reasons. First, soaking in salt water allows the seeds to absorb some additional flavor. Second, pumpkin seeds contain phytic acid, a compound that can bind to minerals in your digestive system and reduce how well you absorb them.14 Soaking may help reduce the phytic acid content and ease digestion.15

To soak pumpkin seeds:

  • Clean seeds out of the pumpkin and rinse off any flesh.
  • Place seeds in a large bowl with a generous amount of salt and cover with water.
  • Allow to soak for about eight hours or overnight.
  • Drain, rinse, and dry thoroughly before roasting.

Sprouted Pumpkin Seeds

You can also soak pumpkin seeds to make sprouted pumpkin seeds. Soak for one to two hours in a jar with water and salt, drain, place a cheesecloth over the top, and keep the jar upside down for eight to twelve hours.

One important note: the FDA has flagged that seeds left in ambient-temperature water for 24 hours may allow bacteria like Salmonella to grow.16 Young children, older adults, pregnant people, and anyone who is immunocompromised should avoid sprouted seeds of any kind.17

How to Eat Pumpkin Seeds

Pumpkin seeds work sweet or savory and are genuinely versatile. Some ways to use them:

What to Look for When Buying Pumpkin Seeds

When buying packaged pumpkin seeds, look for a short ingredient list with no unnecessary additives.18 A good option is organic, unsalted or lightly salted, with no added oils or sugar coatings. Raw, roasted, and sprouted versions are all nutritionally solid, it mostly comes down to preference and how you plan to use them.

On storage: if you roast seeds yourself from a fresh pumpkin, they’ll keep in the fridge for 10 to 14 days.19 Store-bought pumpkin seeds, once opened, do best in an airtight container in a cool, dry pantry for up to six months, or transfer them to the refrigerator to extend their shelf life by slowing down lipid oxidation.20

Side Effects: Who Should Go Easy on Pumpkin Seeds?

For most people, pumpkin seeds are well-tolerated in reasonable amounts. The main risk of eating raw pumpkin seeds in large quantities is digestive discomfort, particularly from the fibrous shells. In rare cases, a significant buildup of undigested shells could make it harder to pass bowel movements.21 Drinking plenty of water when eating high-fiber foods helps.

If you’re ramping up your fiber intake, do it gradually to give your digestive system time to adjust. Those with seed allergies should check with their doctor before eating pumpkin seeds. And because they’re calorie-dense, 163 calories per ounce of pepitas, anyone monitoring their calorie intake may want to keep an eye on portion size.

FAQs

Are pumpkin seeds good for you?

Yes. They’re a good source of protein, magnesium, and iron. One ounce of hulled pepitas contains 8.45g of protein, around 37% of the daily recommended magnesium intake, and meaningful amounts of iron, and all in a small, portable serving.

How many pumpkin seeds should I eat a day?

About 1 oz (28 grams) per day is a practical portion. That’s roughly ¼ cup of shelled pepitas, or a bit more volume if you eat them in the shell.

Are pumpkin seeds good for your skin?

Pumpkin seeds provide zinc and vitamin E, both of which play a role in skin health,22 but there are no direct clinical trials on pumpkin seeds and skin outcomes specifically. It’s a reasonable connection, but not one we’d overstate.

Is pumpkin seed oil good for you?

Small studies show potential benefits from pumpkin seed oil for heart health, hair growth, and menopausal symptoms.23 Use it as a finishing oil — its flavor and nutrient profile degrade under high heat, so it’s not a good candidate for high-temperature cooking.

Are roasted pumpkin seeds as healthy as raw?

Nutritionally, yes. Roasted and raw pumpkin seeds are very similar. Just watch for added salt and oil in pre-packaged roasted options.

What are the nutritional benefits of pumpkin seeds?

Pumpkin seeds are a good source of fiber (especially in the shell), and an excellent source of magnesium and plant protein as pepitas. They also provide iron, zinc, phosphorus, and polyunsaturated fats. See the full nutrition table above for specifics by serving size and form.

The Bottom Line

Pumpkin seeds are genuinely worth eating regularly (not just when you’ve got a pile of them from a Halloween pumpkin). The strongest case for them is built on magnesium, plant protein, fiber, and heart-health supporting fats. The research on prostate health, hair, and menopausal symptoms is interesting but earlier-stage, and the sleep connection is indirect at the portions most people eat.

Whether you roast them, add them to your morning oatmeal, or blend them into a sauce, one ounce a day is a practical and nutritionally worthwhile habit.
