Written and reviewed in-house by Russ Guillemot, founder, drawing on fifteen years of direct correspondence with customers and wholesale accounts. We are not physicians and nothing here is a diagnosis or a course of treatment.
Where we reference published research we name the authors and the journal so you can look it up yourself. Where something is a common observation rather than a finding, we say so plainly. If a claim cannot be sourced, we leave it out.
