Chlorella for Nutrient Absorption

Research suggests that Chlorella may support nutrient absorption indirectly, primarily through its potential to bind harmful compounds like aflatoxins in the gastrointestinal tract and improve intestinal structure under certain conditions, though the available evidence is largely drawn from animal and laboratory studies rather than human clinical trials. A 2024 review of poultry research found that Chlorella and related microalgae showed promise in counteracting aflatoxin-related damage to nutrient uptake and gut health, while a separate 2024 poultry feeding study using Chlorella sorokiniana reported that a low dose appeared to improve intestinal changes associated with better nutrient absorption, whereas a higher dose produced harmful effects — underscoring that outcomes appear highly dose-dependent. Several of the remaining studies in this collection focus on wastewater treatment, environmental toxicology, and algal cultivation methods, making them largely peripheral to questions of nutrient absorption in humans or animals. Overall, the evidence base is limited in scope and species relevance, and no human trials were identified among these studies, so firm conclusions about Chlorella's role in human nutrient absorption cannot be drawn from this body of research.
