Pumpkin is one of the most vitamin A-rich foods you can eat. A single cup of cooked pumpkin delivers roughly 245% of your recommended daily intake of vitamin A, making it hard to beat as a source of this nutrient. But vitamin A is just the headline. Pumpkin also provides meaningful amounts of vitamin C, vitamin E, and several B vitamins, with a slightly different profile depending on whether you’re eating the flesh or the seeds.
Vitamin A and Beta-Carotene
The deep orange color of pumpkin comes from beta-carotene, a pigment your body converts into vitamin A. This conversion is what makes pumpkin such a powerhouse for eye health, immune function, and cell growth. One cup of cooked pumpkin covers well over a full day’s worth of vitamin A, which is unusual for a whole food with so few calories.
There’s an interesting wrinkle, though. People vary widely in how efficiently they absorb beta-carotene from food and convert it into usable vitamin A. Research from the USDA’s Agricultural Research Service confirmed that this conversion rate differs significantly from person to person, and scientists still don’t fully understand all the steps involved. Other carotenoids present in pumpkin may play a supporting role in the process.
Because vitamin A is fat-soluble, your body absorbs it much better when you eat pumpkin alongside some dietary fat. A drizzle of olive oil, a pat of butter, or pairing pumpkin with cheese or nuts can make a real difference in how much of that beta-carotene you actually use.
Vitamin C
Fresh cooked pumpkin provides a good amount of vitamin C, though it’s not in the same league as citrus fruits. Vitamin C supports your immune system and helps your body produce collagen, which keeps skin and connective tissue healthy. It also acts as an antioxidant, working alongside the carotenoids already present in pumpkin. One thing to keep in mind: vitamin C is sensitive to heat, so longer cooking times reduce the amount you get.
B Vitamins and Vitamin E
Pumpkin flesh contains smaller but still useful amounts of several B vitamins, including folate and riboflavin (B2). Folate is essential for cell division and is especially important during pregnancy. Riboflavin helps your body convert food into energy. These aren’t present in huge quantities in pumpkin flesh alone, but they add up as part of a varied diet.
Vitamin E shows up in modest amounts in the flesh and in higher concentrations in pumpkin seeds. It’s another fat-soluble antioxidant, meaning it protects your cells from damage and works best when consumed with some fat.
Vitamins in Pumpkin Seeds
Pumpkin seeds have a notably different nutritional profile from the flesh. They’re much higher in protein and fat, with a 50-gram serving providing about 15 grams of protein and 20 grams of fat. On the vitamin side, seeds contain small amounts of vitamin E, riboflavin, folate, and carotenoids. Their real strength, though, is minerals: they’re packed with magnesium, zinc, copper, manganese, phosphorus, and iron.
If you’re eating pumpkin mainly for vitamins, the flesh is where most of the action is, particularly for vitamin A and vitamin C. But adding roasted seeds gives you a mineral boost and extra vitamin E that the flesh doesn’t provide in large amounts.
Canned Pumpkin vs. Fresh
Canned pumpkin is often more nutrient-dense than fresh cooked pumpkin, which surprises a lot of people. Cup for cup, canned pumpkin contains more carotenoids (the precursors to vitamin A) and more than double the fiber, jumping from about 3 grams per cup in fresh to 7 grams in canned. Canned pumpkin also supplies roughly a fifth of your daily iron needs.
One quirk worth knowing: cans labeled “100 percent pumpkin” can legally contain a mix of pumpkin and other golden-fleshed squash varieties, which tend to be denser and sweeter. Nutritionally, this isn’t a downside. These squash relatives have a similar vitamin profile, and the denser texture is part of why canned pumpkin packs more nutrients per cup. Fresh pumpkin does have an edge in vitamin C, since canning involves heat processing that breaks some of it down.
Key Minerals Worth Noting
While the search here is about vitamins, pumpkin’s mineral content is hard to ignore because it’s substantial. A cup of canned pumpkin provides about 505 milligrams of potassium, which is comparable to a medium banana. It also delivers around 56 milligrams of magnesium. Potassium supports healthy blood pressure, and magnesium is involved in hundreds of enzyme reactions throughout your body, including muscle and nerve function. Combined with the vitamin profile, this makes pumpkin one of the more nutritionally complete vegetables you can eat for its calorie cost.
