Chlorella vulgaris, henceforth “chlorella”, is a simple green algae that has a lot of health benefits.
Note: most of the studies here are for Chlorella vulgaris specifically. However, some are for other species of the Chlorella genus, of which Chlorella vulgaris is by far the most common, hence the name (vulgaris = common). The relevant phytochemical properties appear to be the same regardless.
Superfood
While people generally take it as a supplement rather than a food item in any kind of bulk, it is more than 50% protein and contains all 9 essential amino acids.
As you might expect of a green superfood, it’s also full of many antioxidants, most of them carotenoids, and these pack a punch, for example against cancer:
It also has a lot of vitamins and minerals, and even omega-3.
Which latter also means it helps improve lipids and is thus particularly…
Heart healthy
❝Daily consumption of Chlorella supplements provided the potential of health benefits reducing serum lipid risk factors, mainly triglycerides and total cholesterol❞
Its heart-healthy benefits don’t stop at lipids though, and include blood pressure management, as in this study that found…
❝GABA-rich Chlorella significantly decreased high-normal blood pressure and borderline hypertension, and is a beneficial dietary supplement for prevention of the development of hypertension. ❞

May remove heavy metals
We’re going with “may” for this one as we could only find animal studies so far (probably because most humans don’t have megadoses of heavy metals in them, which makes testing harder).
Here’s an example animal study, though:
Enhanced elimination of tissue methyl mercury in [Chlorella]-fed mice
Immunostimulant
This one’s clearer, for example in this 8-week study (with humans) that found…
❝Serum concentrations of interferon-γ (p<0.05) and interleukin-1β (p<0.001) significantly increased and that of interleukin-12 (p<0.1) tended to increase in the Chlorella group.
The increments of these cytokines after the intervention were significantly bigger in the Chlorella group than those in the placebo group. In addition, NK cell activities (%) were significantly increased in Chlorella group, but not in Placebo group.
The increments of NK cell activities (%) were also significantly bigger in the Chlorella group than the placebo group.
Additionally, changed levels of NK cell activity were positively correlated with those of serum interleukin-1β (r=0.280, p=0.047) and interferon-γ (r=0.271, p<0.005).❞
tl;dr = it boosts numerous different kinds of immune cells
PS, if you click though to the study, you may be momentarily alarmed by the first paragraph of the abstract that says “However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans“
👆 this is from the “Background” section of the abstract, so what they are saying is “before we did this study, nobody had done this yet”.
So, be assured that the results are worthwhile and compelling.
Is it safe?
Based on the studies, it has a good safety profile. However, as it boosts the immune system, you may want to check with your doctor if you have an autoimmune disorder, and/or you are on immunosuppressants.
And in general, of course always check with your doctor/pharmacist if unsure about any potential drug interactions.
