How We Score the Signal

What this site is for

Supplement ingredients go through cycles of attention. Something that sat quietly on a shelf for decades turns up in every feed for a month, usually with a story attached that runs ahead of what anyone has measured. Emerging Health Signals takes ingredients that are getting that attention and asks one plain question of each: for this specific use, how strong is the human research? We report the answer as a reading from one to five bars, explain it with sources you can open, and describe the hype next to it without repeating it as a claim.

The signal scale

Each entry gets one reading for one specific use, named on the page ("Signal for …"). The level follows these definitions. When the evidence sits between two levels, we choose the lower one.

Three things the scale is not. It is not a safety rating: a faint signal does not mean an ingredient is harmful, and a strong one does not mean it is right for you. It is not a quality rating for the product: the reading describes research on the ingredient, while the product sections describe the label, the price and any verified testing. And it is not a verdict on every use: a strong reading for one outcome says nothing about the other things an ingredient is marketed for.

How a reading is justified

• The reading is argued on the page. Every entry states the level, a one-word rationale, and the specific sources that set it, with numbered citations. The "What the research shows" section explains those sources: what kind of study, how many people, how long, and what was actually measured, where the source says so.
• Authoritative sources first. We start from the NIH Office of Dietary Supplements (ODS) fact sheets, the National Center for Complementary and Integrative Health (NCCIH), Cochrane reviews, and systematic reviews and trials indexed in PubMed. We describe what those sources found, with their hedges left in.
• Study dose compared with label dose. Each entry puts the amount and form used in the key research beside what one serving of the product provides. If the label does not state the active compound, the entry says so, and the reading reflects that uncertainty.
• Hype described, never repeated. The "What the hype says" column describes how the ingredient is discussed, in our own neutral words. We do not quote marketing claims, we do not name people, and we do not reproduce claims even to knock them down.
• No overclaiming vocabulary. We never describe any ingredient or product as "proven", and research findings are described as findings, for the people who were studied.
• Readings can change. When we review an entry and the evidence has moved, the reading moves with it, and the entry notes what changed.

How a product earns a place

Every ingredient is shown through one product that sells it plainly. The product has to pass the same checks before it gets an entry.

• An established brand with a live listing on Amazon.com. We open the listing ourselves and confirm the title, the brand's store, the exact size or variation, and that it is in stock. We do not cover direct-to-consumer products sold only through their own websites.
• The label, read literally. The Supplement Facts or Nutrition Facts panel from the listing and from the manufacturer's page: serving size, amount of the ingredient, other ingredients, number of servings. We report what is printed.
• A price with a date on it. Every price on this site says when we saw it, which size and which seller. We never write "currently", and we ask you to check the Amazon page before buying.
• Certifications checked at the source. A seal appears only if we found it on the listing or the manufacturer's page and, wherever the program publishes one, in the certifier's own directory. USP Verified, NSF Contents Certified, NSF Certified for Sport and Informed Choice are different programs, and "made in a GMP facility" or "third-party tested" are not seals at all.

How we make money

Emerging Health Signals earns money in exactly one way: the Amazon Associates program. As an Amazon Associate we earn from qualifying purchases. Every product button on this site goes to that product's Amazon listing, and if you buy through it we receive a small commission from Amazon at no extra cost to you.

There is no other affiliate program, no direct-seller link, no sponsored post, no paid placement, and no free product accepted in exchange for coverage. The commission plays no part in whether an ingredient gets an entry or in the reading it receives. The full version is in our Affiliate Disclosure.

What we do not do

• We do not run lab tests. We are a small editorial team without a laboratory. When testing matters, we name the certification program and check its directory, or we say plainly that the testing status is not disclosed.
• We do not give medical advice. Nothing here is written for your particular situation. Supplements can interact with medications and with each other. If you take medication, are pregnant or nursing, or have any existing condition, talk to a clinician or pharmacist before starting anything.
• We do not make disease claims. Readings describe research on structure-and-function outcomes. We do not say that any ingredient addresses a disease, and we keep disease names out of our titles.
• We do not invent people. The byline on every page is Emerging Health Signals Editorial Team. There is no fictional doctor reviewing entries and no named expert or influencer, because we would rather you judge the sourcing than a face.
• We do not sell or ship anything. Every purchase happens on Amazon under Amazon's own terms. See Shipping and Returns.

Who writes this

Emerging Health Signals is published by Aurora Group Platforms LLC, a Wyoming company. The pages are written and maintained by a small editorial team. We are not clinicians, dietitians or scientists, and we do not claim to be. What we bring is a process: find the claim, find the study type, compare the dose, open the listing, read the label, date the price, and say when we could not confirm something.

Corrections

If something on this site is wrong, we want to fix it: a reading you think is too generous or too harsh, a study we described inaccurately, a price that has moved, a serving size we misread, a certification that has lapsed, a link that has died. Write to us through the Contact page with the page address, the sentence or number you believe is wrong and, if you have one, a source we can open ourselves.

When we confirm an error we correct the page and update its review date. If the correction changes a reading or what the entry says about a product, we add a short note on the page saying what changed.

How often pages are reviewed

Every entry and explainer carries the date it was last checked. Our working rule is to re-open every Amazon listing we link to at least once a quarter, confirming that the ASIN still resolves to the same product and variation, that it is in stock, and that the label has not been reformulated; and to look for new pooled reviews on the ingredient whenever we touch its entry. Between reviews a listing or the research can change without telling us, which is why the date on the page is the only date that counts.
