Microgreens are tiny seedling of plants (vegetables, oil-seeds, culinary and medicinal herbs) that have become incredibly popular in recent years because of their remarkable nutritional profile and flavor. Microgreens are harvested at a tender age of just 2–3 weeks after germination and are rich in antioxidants, vitamins and minerals (iron, calcium, magnesium). However, microgreens are functional foods that not only provide essential nutrition, but also contain additional components such as bioactive compounds or phytochemicals that enhance certain aspects of health. Bioactive compound may improve immunity, inflammation, digestion and even risk of certain life-threatening ailments like cancer, diabetes, hypertension and cardiovascular diseases at some extent. Therefore, microgreens are considered as live functional food that support the immune system through increasing its ability to fight against infections and diseases. These little greens are easy to grow in soil or hydroponic system and incredibly rich in macro as well as micro nutrients and packed full of bioactive compounds like carotenoids, phenols, glucosinolates. Interestingly, microgreens may be biofortified with desirable minerals through nanotechnology to treat the target diseases. They serve as a nutritious addition to daily diets, supplements and explored as medicine in pharmaceutical field as validated through in vitro and in vivo research due to their antioxidant, anticancer, antibacterial, anti-inflammatory, anti-obesity, and antidiabetic properties. Moreover, microgreens are considered as space food for sustainable food production under climate-vulnerable area. Due to less awareness of microgreen properties, marketing strategies and commercialization approaches need to be addressed in societies. Therefore, good marketing approaches, business processes and models has also been explained to establish the microgreen nutraceutical and pharmaceutical industry as nascent employment field.
