Phytoplankton refers to a diverse group of microscopic marine algae, including species like Nannochloropsis and Thalassiosira, that are rich in nutrients such as omega-3 fatty acids (notably EPA), vitamins, minerals, and antioxidants. There is some emerging scientific interest in phytoplankton as a nutritional supplement, with a small number of studies exploring its effects on human health, including mitochondrial function. The mitochondria are the energy-producing organelles in cells, and their performance is influenced by cellular nutrition and the presence of oxidative stress.

A few preliminary studies, primarily in vitro (cell culture) or in animal models, suggest that phytoplankton extracts may support mitochondrial function by providing antioxidant compounds (such as carotenoids, chlorophyll, and polyphenols) that could reduce oxidative damage to mitochondria. Additionally, the presence of omega-3 fatty acids may indirectly support mitochondrial membrane health. However, evidence in humans is limited: very few clinical trials have directly examined the effect of phytoplankton supplementation on mitochondrial markers or energy metabolism in people. Most claims about benefits to mitochondrial health are extrapolated from the nutrient profile of phytoplankton rather than demonstrated physiological effects.

In summary, while there is a plausible nutritional rationale and some early-stage scientific investigation, robust human evidence is lacking. Thus, the use of phytoplankton to support mitochondrial health is supported by limited scientific evidence, and more research is needed to validate these effects in humans.
