Evidence First
Every recommendation is backed by human clinical data, not just animal studies or mechanistic plausibility. We consider dose, study design, and known limitations.
Value Bar
We list price ranges and flag when a cheaper alternative is nearly as good. Expensive doesn’t mean better — we call it out when it matters.
No Filler
We don’t pad lists with mediocre products. If only one or two options genuinely clear the bar, that’s what we list.
