Rating (out of 5): 2

Chlorella, a freshwater green microalga, is sometimes recommended as a supportive supplement during convalescence (the recovery period following illness or medical treatment). The rationale behind its use is primarily based on its rich nutrient profile, including high-quality protein, vitamins (such as B12 and folate), minerals, antioxidants, and chlorophyll. Scientific evidence supporting chlorella’s role in convalescence is limited but emerging. Some small-scale clinical studies and animal research suggest that chlorella supplementation may enhance immune function, reduce oxidative stress, and improve nutritional status—factors that could theoretically aid the recovery process.

For example, some studies have shown that chlorella supplementation can increase levels of immunoglobulins and natural killer cell activity, potentially supporting immune recovery. Other research indicates that chlorella may help reduce fatigue and improve quality of life in individuals with chronic illnesses, though these studies often have small sample sizes and are not specific to the general convalescent population. Overall, while the nutrient density of chlorella provides a plausible benefit during recovery from illness, robust clinical evidence directly supporting its use for convalescence is lacking. Most recommendations are extrapolated from its general effects on health and nutrition. Thus, while there is some scientific rationale, more high-quality, targeted research is needed to conclusively support its efficacy in this context.
