Microalgae represent a diverse group of photosynthetic microorganisms that are gaining importance in dietary supplement production due to their unique bioactive components and high nutrient density. They are rich in essential fatty acids, particularly omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), vitamins, minerals, antioxidants, and high-quality proteins, making them an integral part of a health-conscious diet.
The genera Spirulina and Chlorella are of specific interest to the dietary supplement industry. Spirulina is distinguished by its high content of proteins, vitamin B12, and beta-carotene, while Chlorella is valued for its chlorophyll content and ability to bind and eliminate heavy metals from the body.
The mode of action of microalgae is based on their antioxidant capacity, which minimizes cell damage caused by free radicals, and their anti-inflammatory effects, which can contribute to the prevention of chronic diseases. Additionally, microalgae support general health, the immune system, and gut flora due to their high nutrient content.
For optimal product development, it is crucial to use extraction and processing methods that preserve the integrity of sensitive ingredients. In this way, microalgae offer significant potential for the development of innovative dietary supplements.
