Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Algal protein, derived from various algae such as spirulina and chlorella, is used in dietary supplements and functional foods to support energy levels, primarily due to its high protein content and presence of micronutrients like B vitamins and iron. Scientific evidence supporting its use for treating or preventing "lack of energy" is modest and indirect. A small number of human and animal studies have shown that supplementation with spirulina or chlorella can improve fatigue, particularly in populations with nutritional deficiencies or certain health conditions (e.g., anemia, chronic fatigue). The mechanism is thought to be related to improved nutrient intake—especially iron and B vitamins—which are essential for energy metabolism. For example, a 2016 study in older adults found that spirulina supplementation improved markers of fatigue, possibly due to its iron content. However, these findings are not robustly replicated, and most studies are small or have methodological limitations.

There is no strong direct evidence that algal protein specifically boosts energy in healthy individuals, and the effect appears to be due to its role as a nutrient-dense food rather than any unique property of algae. In summary, there is some scientific rationale and limited clinical evidence for algal protein supporting energy in those with certain deficiencies, but the overall evidence base is weak, warranting a moderate-to-low rating.
