What the Science Says
Pumpkin seed powder is made from ground pumpkin seeds and is rich in protein, healthy fats, zinc, magnesium, and antioxidants. Traditional use and animal research suggest it may support blood sugar balance and reduce oxidative stress, but no human clinical trials have confirmed these effects. It is commonly added to foods and supplements as a nutritional booster rather than a targeted therapeutic ingredient.
What It Doesn't Do
Not proven to treat or prevent diabetes in humans. No clinical evidence it improves prostate health, despite popular marketing claims. Won't meaningfully boost testosterone based on available data. Not a substitute for medical treatment of any condition.
