Potential Health Benefits of Pumpkin Seed Oil Revealed

Introduction to Pumpkin Seed Oil

Pumpkin seed oil has become increasingly popular in recent years due to its multitude of potential health benefits. Derived from pressing the seeds of pumpkins, this oil has been used for centuries in folk medicine, but modern research is also uncovering its unique properties and bioactive compounds that may be responsible for its effects.

With a rich, nutty flavor and striking dark green color, pumpkin seed oil makes a tasty cooking oil or salad dressing ingredient. However, its potential medicinal properties have made it a staple in natural medicine and an emerging functional food.

Keep reading to learn about the top 5 evidence-based health benefits of pumpkin seed oil.

1. May Promote Prostate Health

One of the most well-researched uses of pumpkin seed oil is for supporting prostate health, especially benign prostatic hyperplasia (BPH), commonly known as an enlarged prostate.

Animal and human studies have found that extracts from pumpkin seeds and pumpkin seed oil may be beneficial for supporting prostate health and treating symptoms of BPH.

This is thought to be due to their rich content of nutrients like zinc, magnesium, and phytosterols. The oil may help inhibit the conversion of testosterone into dihydrotestosterone (DHT), a hormone that contributes to enlarged prostate when levels are too high.

According to a 2011 review, men with BPH who took pumpkin seed oil daily for 6–12 months showed improvements in symptoms like frequent urination, incomplete bladder emptying, and interrupted sleep due to urination.

While more studies are needed, pumpkin seed oil shows promise as a natural way to maintain prostate health, especially for men with BPH.

May Improve Bladder Function

Issues with bladder function, such as overactive bladder, are commonly associated with BPH and an enlarged prostate. The oil’s potential prostate-protective effects may also benefit bladder function.

A study in 53 men with BPH found that taking a combination of pumpkin seed oil and saw palmetto oil daily for 6 months improved self-reported urinary symptoms and quality of life.

Additionally, a rat study showed that pumpkin seed oil reduced bladder pressure and increased bladder compliance, suggesting it may aid bladder function.

While more studies are needed, pumpkin seed oil’s ability to promote prostate and bladder health suggests it may be useful for improving urinary symptoms.

2. Rich in Antioxidants

Pumpkin seeds and their derivatives are loaded with antioxidants that may provide a variety of health benefits.

Some of the antioxidants found in pumpkin seed oil include:

• Carotenoids like beta-carotene
• Vitamin E
• Zinc
• Phytosterols

Research shows that these antioxidants have anti-inflammatory effects in the body and help neutralize harmful free radicals that can damage cells.

Animal studies have found that pumpkin seed oil supplements can increase levels of antioxidant enzymes like superoxide dismutase, boosting the body’s defenses.

The oil’s antioxidant content may translate to other benefits as well, including reduced inflammation, healthier cholesterol levels, and decreased oxidative stress that can contribute to chronic diseases.

May Reduce Inflammation

Chronic inflammation is at the root of most diseases. The antioxidants in pumpkin seed oil, especially carotenoids like beta-carotene, may help fight inflammation.

Cell and animal studies show that pumpkin seed oil reduces levels of inflammatory cytokines, proteins involved in inflammation.

It also appears to decrease nitric oxide production, which plays a role in inflammatory conditions like arthritis and inflammatory bowel disease.

The significant anti-inflammatory properties of pumpkin seed oil could contribute to its proposed benefits for health issues associated with chronic inflammation.

3. Supports Heart Health

Heart disease is the worldwide leading cause of death. Nutrition and lifestyle choices play a major role in heart health.

Some evidence suggests that pumpkin seed oil could benefit certain heart disease risk factors and markers of cardiovascular health.

May Improve Cholesterol Levels

Animal studies have found that pumpkin seed oil may reduce cholesterol levels. This is attributed to its phytosterols, plant-based compounds with structures similar to cholesterol.

Phytosterols reduce cholesterol absorption in the gut. They also benefit the ratio of low-density lipoprotein (LDL) or “bad” cholesterol to high-density lipoprotein (HDL) or “good” cholesterol.

A study in rats fed pumpkin seed oil had significantly lower LDL and total cholesterol levels, as well as anti-inflammatory effects.

While most studies use concentrated pumpkin seed extracts, pumpkin seed oil’s high phytosterol content could produce similar cholesterol-lowering benefits.

Reduce Blood Pressure

High blood pressure is one of the major risk factors for heart disease. Animal studies suggest pumpkin seed oil may reduce blood pressure levels.

This effect is often attributed to the oil’s content of phytosterols as well as minerals like magnesium and zinc, which may help dilate blood vessels.

Research shows that supplements combining pumpkin seed oil with other plant oils reduced blood pressure in hypertensive rats. Human studies are needed.

The potential antihypertensive effects of pumpkin seed oil could benefit heart health by decreasing strain on the heart.

4. May Promote Hair Growth

Pumpkin seed oil is often added to hair products like shampoos and hair masks or used as a standalone treatment.

Some claim it may thicken hair, reduce hair loss, and stimulate growth. Does it actually work?

While evidence is limited, pumpkin seed oil’s nutrient profile could theoretically benefit hair health.

It provides vital nutrients for hair like zinc, iron, and vitamin K. Zinc is especially important for hair growth and deficiency is linked to alopecia, a type of hair loss.

The oil is also a source of omega-6 fatty acids that may exhibit hair growth effects. However, more studies specifically evaluating pumpkin seed oil are needed.

Anti-Inflammatory and Antimicrobial Benefits

Chronic scalp inflammation can disrupt the hair growth cycle and cause excessive shedding. The anti-inflammatory activity of pumpkin seed oil may help.

Test-tube studies demonstrate it reduces inflammation-provoking cytokines. When applied to the scalp, this may translate to benefits for chronic inflammatory conditions that impair hair growth.

The oil may also combat microorganisms that infect hair follicles and cause hair loss. Pumpkin seed extracts show antimicrobial effects against fungi associated with folliculitis and dandruff.

Pumpkin seed oil’s ability to fight inflammation and infection could mean fewer scalp problems that interfere with healthy hair.

5. May Improve Sleep

Pumpkin seeds are one of the few food sources of tryptophan, an amino acid involved in sleep.

Tryptophan is converted to neurotransmitters like serotonin and melatonin, which regulate your sleep-wake cycles and help you fall and stay asleep.

While it’s unlikely that pumpkin seed oil provides enough tryptophan to significantly increase sleep-promoting neurotransmitters, it does provide small amounts that may work synergistically with the oil’s other compounds.

Zinc in pumpkin seed oil may also improve sleep. One study found that zinc supplements reduced insomnia symptoms and serum zinc levels were lower in those with insomnia.

Additionally, animal studies show that the antioxidants in pumpkin seed oil may improve sleep by reducing inflammation, a known risk factor for sleep disturbances.

insomnia.

May Reduce Anxiety

Anxiety often disrupts sleep patterns. Animal studies suggest pumpkin seed oil may reduce anxiety, another mechanism by which it could improve sleep.

Mice fed pumpkin seed oil for 30 days exhibited anti-anxiety effects, measured by increased time spent in the open arms of a maze, indicating reduced anxiety.
