Not interested in getting into an Internet argument over credentialism, but I will say that I did some looking at examine.com's treatment on spirulina, and found it to be less than compelling.
It still commits the same fundamental mistake made by any other popular sources that covers supplements: it doesn't really give study quality adequate attention. Instead, it just accepts all published findings as probably being valid. What with the replicability rate for medical research papers being somewhere around 20%, that's an approach that will lead you astray 4 times out of 5.
As a concrete example, the support they give for the first item in the table of results, lipid peroxidation, is three papers with n=37, n=16 and n=9. All of them throw some flags that make me suspect p-hacking may have occurred, with the n=37 one being the most worrisome in that department.
