Our Verdict
It ranks first because it combines independent verification, unambiguous fruiting-body sourcing and the list's strongest beta-glucan disclosure. Gaia has a more comprehensive extraction method, but Real Mushrooms is substantially stronger on the more heavily weighted verification and transparency criteria.
