The marketed products are mainly based on production strains, i.e., Spirulina and Chlorella in the composite situation, since two of them are cyanobacteria and the second one is eukaryotic. In the marketed form and several utilizations, and peculiarities that need special attention and adequate studies. General report is about the current scientific knowledge on each microalga, in particular the nutritional value and properties in prevention and wellbeing. Second, original studies are presented concerning the quality control of marketed products. Quality control is act as key argument in nutraceuticals validation. Microalgae one of particular organisms that need specific approaches to check identity and validate properties of microalgae. The paper is dedicated to the need for specificity in uses and to considerations about the future of microalgae in food supplements in our daily needs. India is a country with heterogenic population having diverse food habits become a driving force in the shift towards a greater recognition between diet and health care in research the use of few natural unprocessed foods like blue-green algae “spirulina” which has a galaxy of nutrients as diet supplements. The purpose of the present review is to compile evidence regarding the health benefits of spirulina, amount of evidence on health benefits are its effect in preventing anaemia, blood sugar and obesity many health diseases.
