Épinard (Spinacia olearacea)

Spinach (Spinacia oleracea) is a leafy plant native to Central Asia, now widely cultivated across the globe. It is naturally rich in vitamins (A, C, K, and folate) and minerals (iron, magnesium, calcium, and potassium), as well as carotenoids such as lutein and zeaxanthin, and natural nitrates. Its bioactive compounds contribute to overall nutritional balance. Folate supports normal DNA synthesis and helps reduce tiredness and fatigue. Vitamin K contributes to normal blood clotting and the maintenance of healthy bones. Lutein and zeaxanthin are associated with the maintenance of normal vision. The natural nitrates found in spinach are also studied for their role in cardiovascular health. As a dietary supplement, spinach extract provides a concentrated, standardised intake of its key micronutrients. This makes it a relevant option for individuals whose diet is low in leafy green vegetables or who have elevated needs for specific nutrients.
