Pumpkin Seeds
Pumpkin seeds, like all edible seeds, pack an immense nutritional boost. They are particularly dense in zinc which is needed for testosterone health. Nature equips these seeds with an extremely dense source of organically-bound nutrients, including exceptionally high levels of key, health-promoting minerals. For example, a one cup serving of pumpkin seeds has 44% recommended daily allowance (RDA) of zinc, 22% of copper, 42% magnesium, 16% manganese, 17% potassium, and iron (17%).
Prostate health
Pumpkin seed extracts and oils may play a role in treating enlarged prostate. Research suggests that both pumpkin seed oil and pumpkin seeds may be particularly beneficial in supporting prostate health.
Sleep
Pumpkin seeds are a rich source of tryptophan, an amino acid (protein building block) that your body converts into serotonin, which in turn is converted into melatonin, the "sleep hormone.
With the highest dose of the amino acid per serving, pumpkin seeds provide 110 milligrams per 30g serving. Tryptophan achieves its effects by way of serotonin, one of the key brain chemicals involved in regulating mood. Among other functions, serotonin promotes feelings of calm, relaxation, and sleepiness. Sunflower seeds will decrease stress and cortisol levels.
