Research suggests that Spirulina may play a role in nutrient absorption contexts, though the available evidence is largely indirect and drawn from non-human studies. A 2024 review found that Spirulina and related microalgae can bind aflatoxins in the gastrointestinal tract of poultry, reducing their absorption and supporting nutrient uptake in contaminated feed conditions, while a 2023 aquaculture study indicated that spirulina-enriched insect meal supported normal nutrient processing and digestive health in freshwater prawns without adverse effects. Two additional studies — one examining Spirulina-derived biochar in rice cultivation and another assessing its capacity to absorb pollutants from wastewater — touch on Spirulina's broader nutrient-uptake properties but are not directly relevant to human or even animal dietary absorption. Overall, the evidence base consists of reviews, animal feeding trials, and agricultural or environmental studies rather than controlled human trials, making it difficult to draw firm conclusions about Spirulina's effects on nutrient absorption in people.
