This site's own comparison table uses two specific classifications worth understanding precisely: "within range" and "cannot verify."
"Within range" means the disclosed label amount falls inside the typical published research range for that ingredient. "Cannot verify" means the amount isn't disclosed clearly enough to make that comparison at all.
A single "good" or "bad" rating would obscure the real, mixed picture — two ingredients genuinely check out against research doses, while two genuinely can't be checked, and treating those as different categories gives you a more accurate, actionable picture.
