This page explains how Comfortable Aging researches, writes and updates its articles, and what we will and will not do.
Our rules
- Nothing invented. No fictional experts, no made-up studies, no fake reviews or testimonials.
- Every health statement has a source. If we say an ingredient may help with something, the article links to the study or public health source that supports it.
- We do not go beyond the source. If a study was small, short, done in a lab or in animals, or used a different dose than the product, we say so.
- Marketing is not evidence. Product sales pages often make bigger claims than the research supports. We do not repeat those claims.
- Real testimonials only. We only quote customer experiences that are public and verifiable, and we always say where they come from. We never write testimonials ourselves.
- We tell you what we have not done. Unless an article says otherwise, we have not personally tested the products we review. Our reviews are research reviews: we look at the ingredients, the doses (when the label shows them), the evidence behind them, the price and the refund terms.
Which sources we use
We prefer, in this order:
- Systematic reviews and meta-analyses of human studies (for example, from PubMed and the Cochrane Library).
- Randomized controlled trials in humans.
- Public health and government sources, such as the NIH Office of Dietary Supplements, the National Center for Complementary and Integrative Health (NCCIH), the National Eye Institute, MedlinePlus and the FDA.
- Guidance from established medical organizations.
We do not use other affiliate sites, press releases or product sales pages as evidence. We may cite a sales page only to show what the seller claims, and we label it that way.
How we use AI
We use AI tools to help us find studies, read and summarize them, and write first drafts. AI tools can make mistakes, so we never publish AI output unchecked. Before an article goes live, the editor, Flávio Sabugo, checks that every health statement matches its cited source, that the cited source exists and says what we say it says, and that the article follows the rules on this page.
Flávio is not a health professional. His role is editorial: accuracy against sources, clarity and honesty. He does not give medical opinions.
How we choose products
We only cover products whose main ingredients have published research in humans. Products that rely only on dramatic claims, with no supporting research, stay out of our recommendations even if they pay a high commission. When a product comes in several package sizes, we show the real prices so you can see what you would actually pay, without invented discounts or fake urgency.
Affiliate links and independence
Some links are affiliate links, and we may earn a commission if you buy. Commissions do not change what the evidence says, and they do not buy positive coverage. Read more in our Affiliate Disclosure.
Corrections and updates
Research changes, and we make mistakes. If you find an error, a broken source or an outdated price, please tell us through our Contact page. We review every report, fix confirmed errors and update the date on the article. We also review our main articles regularly to check prices, formulas and new research.
