Algal protein, derived from microalgae such as Spirulina and Chlorella, has gained scientific interest as a sustainable and nutrient-rich protein source. Its relevance to the structural system—comprising bones, muscles, and connective tissues—stems from its complete amino acid profile, which is essential for muscle protein synthesis and maintenance. Scientific studies have demonstrated that algal protein contains all essential amino acids, and some research suggests that supplementation can support muscle mass in vegetarian and vegan populations. Additionally, algal protein is a source of minerals such as calcium and magnesium, which are important for bone health, though the bioavailability of these minerals from algal sources varies. However, direct scientific evidence specifically linking algal protein supplementation with significant improvements in bone density or structural system function is limited. Most evidence relates to its general protein content and role in supporting muscle maintenance, particularly as part of a balanced diet. There is also some preliminary research into bioactive peptides from algae that may support collagen synthesis, but these findings are not yet conclusive. Overall, while algal protein is recognized as a high-quality, plant-based protein source that can contribute to the body's structural system needs, the level of direct scientific validation for its use in enhancing the structural system is modest at present.
