Spirulina is a nutritional supplement, majorly obtained from the two species of cyanobacteria, including arthrospira maxima and arthrospira platensis. Spirulina is defined as a type of algae that grows naturally in the alkaline waters of lakes, ponds, and rivers in warm regions. Spirulina is associated with high nutritional value, including vitamins A, C, E, and B12, and minerals, protein, carbohydrates, and essential lipids. Arthrospira is used in dietary supplements, as whole food, and is available in varied forms such as capsules, tablets, flakes, powder, and liquids. Furthermore, spirulina is extensively used as a feed supplement in aquaculture, aquariums, and poultry industries. On the basis of form, the global spirulina market is segmented into powder, tablets/capsules, liquids, and granules. The powder segment held a dominant position, in terms of volume, in 2016 due to its ease of application as compared to the liquid form. The segment is expected to maintain its dominance during the forecast period, witnessing highest CAGR among others. Furthermore, the tablets and capsules segment is expected to be the second largest segment during the forecast period.
