Spirulina powder is a nutrient-dense superfood derived from blue-green algae (Arthrospira platensis), cultivated in freshwater environments. Renowned for its rich green color and slightly earthy taste, spirulina is packed with plant-based protein, making up about 60–70% of its content. It is also an excellent source of essential vitamins and minerals, including B vitamins, iron, calcium, magnesium, and antioxidants like phycocyanin, which gives spirulina its distinctive blue hue. This powerful antioxidant helps combat oxidative stress and supports immune function. Spirulina is popular among vegetarians, vegans, and health-conscious individuals for boosting energy, supporting detoxification, and promoting overall well-being. It may also help maintain healthy cholesterol levels and support cardiovascular health. Often added to smoothies, juices, and health bars, spirulina powder is easy to incorporate into daily diets. As a sustainable and environmentally friendly food source, spirulina is increasingly valued for both its nutritional benefits and low ecological impact.
