Spinach powder is made from grinding dehydrated spinach leaves in order to retain all of the nutrients found in spinach. Spinach is a naturally nutrient rich vegetable packed full of vitamins and minerals essential for daily function. It's hard to believe that such a simply vegetable of salad leaf can be high in protein but spinach is just that with over 27g of protein per 100g of powder. It is a fantastic way of boosting daily greens!
