Editorial & Research Process

Signal's editorial work is produced by a small in-house team that researches, writes, and reviews every article and product page on this site. Our goal is to give people enough ingredient and routine information to make their own decisions — not to push a single supplement.

How we research

Each article and product description starts from peer-reviewed sources. For ingredients, we lean on the NIH Office of Dietary Supplements fact sheets, PubMed/PMC clinical literature, and standardized-extract documentation (for example, KSM-66 for ashwagandha). When the research is mixed or early-stage, we say so.

How we review

Every health-claim article on this site is reviewed by the Signal editorial team before publication. Where an article references a specific clinical study, we cite the source so you can read the original. We update articles as new research emerges; the published date and last-updated date are both visible on each post.

How we write

Articles are written for adults making real decisions about their routines, not for keyword targets. We avoid hype, avoid medical advice (we are not a clinic), and avoid claims we can't back up. Where a supplement format or routine genuinely doesn't fit a use case, we say that too.

Conflicts of interest

Signal sells supplements. Articles on this site frequently link to products in our catalog when they are directly relevant to the topic. We do not accept paid placement from other brands or ingredient suppliers, and we do not link out to third-party retailers as paid affiliates.

Corrections

If you find an error, an out-of-date source, or a claim that needs better support, please email the editorial team and we will review and update.
