The Surprising Immune Health Benefits of Pumpkin
Amy Sunderman, MS, RD • August 25, 2020

There are a lot of interesting facts about pumpkins that many of us aren’t aware of. Like the fact that they’re actually fruits and not vegetables or that they’re made up of about 90% water. One of the even lesser-known facts is that pumpkins are packed with nutrients that can be beneficial to our immune health.

While they might not get the same spotlight as other immune-boosting fruits like oranges or elderberries, pumpkins still provide some pretty impressive vitamins to support immune function and overall wellness.

Vitamin A

Pumpkins are also a great source of vitamin A. Pumpkins contain beta-carotene which is what gives them their iconic orange color. This plant carotenoid is then converted into vitamin A within the body, which helps to maintain lung health and regulate immune cell response. Since only a small percent of over 600 carotenoids can be converted into vitamin A, this compound is a real treat from this traditional pie staple.1,2

Vitamin C

As the second top nutrient, pumpkin is also high in vitamin C. Providing almost 20% of the recommended daily amount per serving, pumpkin is a fun and simple way to incorporate this essential vitamin into your diet. This immune health booster helps neutralize damaging free radicals as well as provide extra support for the immune system by promoting immune cell production and providing antioxidants.3

Vitamin E

Pumpkin seeds are also loaded with immune-boosting essentials, one of which is vitamin E. Like vitamin C, this immune supporter also helps neutralize free radicals. Vitamin E may help repair cells from oxidative damage and enhance the immune response.4 Luckily, the average pumpkin provides around 500 seeds, so there are plenty to go around!


Pumpkin seeds are a great source for a multitude of minerals that promote healthy immune function like iron and zinc, two important nutrients that support the development of healthy immune cells. 5,6 Maintaining healthy levels of these minerals is crucial for immune cell health and in regulating immune function.

Another important mineral found in pumpkin seeds is magnesium. Magnesium plays a key role in immunoglobulin synthesis and immune cell function.7
