Pumpkin seeds

A rare food that's high in both zinc and magnesium — the two mineral pillars of testosterone — in one crunchy handful.

Why it matters

Pumpkin seeds (pepitas) are quietly one of the best hormone foods in the seed world because they're rich in both of testosterone's key minerals at once — zinc and magnesium. Most foods give you one or the other; pumpkin seeds deliver a serious dose of each. Magnesium in particular is exceptional here — pumpkin seeds are among the richest food sources on the planet — and most people don't get enough. They're also a traditional food for prostate health, with the zinc content being a likely reason. For a cheap, portable, crunchy snack, the nutritional return is excellent.

What's inside

Magnesium is the standout — around 592 mg per 100 g, an exceptional amount — supporting testosterone availability, deep sleep, muscle function and stress regulation. Zinc (~7.8 mg) feeds testosterone synthesis directly. Together they cover testosterone's two key mineral inputs. Pumpkin seeds add healthy fats, plant protein, iron and antioxidants, rounding out a genuinely well-balanced little seed.

For men

This is the pumpkin seed's home ground: zinc for testosterone production and magnesium for keeping it available and supporting recovery and sleep. The combination is unusually complete for a single food. The traditional link to prostate health — likely zinc-driven — is a further reason pumpkin seeds appear so often in men's-health diets.

For women

For women, the high magnesium is a real asset for sleep, stress and easing premenstrual symptoms like cramps and mood swings, while zinc supports the cycle, skin and thyroid. The iron content is a useful bonus given how common low iron is in women. A handful sprinkled through the day is a simple way to top up minerals that female hormones depend on.

How to eat it

A small handful (~30 g) makes a great snack, but pumpkin seeds shine as a topping — scattered over salads, porridge, yogurt, soups or roasted vegetables for crunch. Raw or lightly toasted both work; skip the heavily salted versions. They're inexpensive and store well, making them one of the easiest mineral top-ups to keep on hand.

Worth knowing

Like all seeds they're calorie-dense, so keep to a handful as a snack (toppings are naturally self-limiting). There are no real downsides for most people beyond portion size. For the cost and convenience, few foods deliver this much zinc and magnesium together.

Bottom line

Pumpkin seeds are one of the few foods rich in both zinc and magnesium — testosterone's two mineral pillars — making a daily handful a simple, cheap win for hormone, sleep and stress support.
