10 Proven Health Benefits of Nutmeg (Backed by Science)

Nutmeg may support digestion, brain function, and overall wellness when consumed in small, safe amounts.
This aromatic spice—derived from the seed of Myristica fragrans—is valued not only for its flavor but also for its potential health-promoting compounds. Rich in antioxidants and essential oils, nutmeg has long been used in traditional medicine for digestive comfort, cognitive support, and immune balance.

Understanding nutmeg’s science-backed benefits helps you use it safely and effectively in your diet. Below, we explore the top evidence-based health benefits of nutmeg, supported by recent studies and nutritional research.

What Is Nutmeg?

Nutmeg (Myristica fragrans) is a warm, aromatic spice derived from the seed of the evergreen nutmeg tree, native to the Banda Islands of Indonesia—historically known as the “Spice Islands.” The seed is dried and ground to produce nutmeg powder, while its surrounding red lacy covering is processed into mace, another valuable spice.

Harvesting involves drying the ripe seeds under sunlight until the kernels shrink and rattle inside their shells. Once dried, the hard shell is cracked to release the nutmeg seed, which can then be ground into powder or used whole for grating in culinary dishes.

In modern kitchens, nutmeg is used globally to add depth and warmth to sweet and savory recipes such as baked goods, curries, soups, and beverages like eggnog or chai. Traditionally, it was also valued in Ayurvedic and Middle Eastern practices for its digestive and soothing qualities.

Today, scientific interest in nutmeg focuses on its natural antioxidants, essential oils, and trace minerals, which contribute to its culinary and nutritional importance.
