What it is
Chlorella is a freshwater microalga supplying protein, pigments, and micronutrients; cell-wall processing changes digestibility.
Core function and why it is studied
Its composition or proposed mechanism makes nutrient adequacy, cardiovascular function logical research areas. Studies therefore examine lipid, glucose, and micronutrient measures. That biological connection explains why it is studied; it does not by itself establish a meaningful benefit.
What the evidence means
Human studies and reviews report variable results. Differences in preparation, dose, duration, population, and outcome selection limit broad conclusions.
How to compare products
Compare species, plant part, extract ratio, solvent, standardized constituents, serving amount, and contaminant testing.
