ABSTRACT
In recent decades, the requirement of natural, sustainable, and novel nutritional products is on great interest for the nourishment of growing population. Being eco-friendly, algae are promising alternative sources to produce a variety of value-added rich products. These bioactive products extracted from algae are not only defensive for human and animal health but also fulfilling the food demand of the large population. The application of algae in pharmaceutical and nutraceutical sectors is stimulating the defense mechanism in living beings as well as also attracting the people towards the use of more natural products instead of chemical products for their health and nutrition. So, the production and application of new algal species should be explored and grown at a large scale. Conversion of algae into bio-active products should be improved at the commercial level so that the large fraction of the world population could use it as immunity booster or enhancer. This chapter discussed and evaluated the use of various algae derived nutraceutical and pharmaceutical value-added rich products in health improvement and also in disease treatment (such as diabetes, cancer etc).
