Microalgae, the oldest photosynthetic microorganisms on Earth, are emerging as disruptive super ingredients in the health and nutrition industry, thanks to their unparalleled nutrient density. Star species such as Spirulina and Chlorella have a protein content as high as 50% to 70%, are rich in all essential amino acids, and serve as an excellent new source of plant-based protein—perfectly aligning with the global trend of vegetarianism and healthy eating. More importantly, microalgae act as “biological factories” for rare nutrients: Haematococcus pluvialis produces natural astaxanthin, one of the most potent antioxidants in nature; Crypthecodinium cohnii is a high-quality source of plant-based DHA, offering a sustainable solution to the challenge of Omega-3 supplementation for infants and pregnant women. Based on this, from functional foods that boost immunity, beauty oral liquids with antioxidant and anti-aging effects, to DHA algal oil that enhances memory and protein powder that regulates blood lipids, their derivatives are emerging in an endless stream. Additionally, microalgae are abundant in various vitamins, minerals, polysaccharides, and chlorophyll, forming a natural package of comprehensive nutrients.

With continuous breakthroughs in biotechnology, precise regulation of the content of bioactive substances in microalgae has become possible, further unlocking its potential for customized health applications. Amid the global trend of pursuing “natural, scientific, and efficient” nutrition, microalgae—integrating green sustainability and high efficiency—will undoubtedly become a key engine driving the future growth of the health and nutrition industry.
