How We Review Products

Every product we cover goes through the same evaluation process, regardless of commission rate or affiliate network. Here is exactly how it works.

The 5-Minute Product Check

Every review opens with a fast, consistent snapshot: what the product is, what it’s marketed for, key ingredients or features, monthly cost, subscription terms, refund policy, and our verdict — with Evidence Level shown directly alongside the verdict, not buried further down the page.

Evidence Level: two ratings, not one

We rate evidence on a five-point scale — Strong, Moderate, Preliminary, Limited, or Insufficient/Unknown — and we rate it twice: once for product-specific evidence (research on the finished formula itself, which is genuinely rare across this entire category) and once for ingredient-level evidence (research on individual components at comparable doses, which is far more common). Conflating the two is a common sleight of hand in supplement marketing — borrowing the credibility of unrelated ingredient science for an untested finished product. We state both ratings explicitly. A product built on strong-evidence ingredients with only preliminary product-specific evidence isn’t automatically a red flag — that’s the normal state of most supplements — but we say so plainly rather than letting one rating imply the other.

Our Evaluation Criteria

Every reviewed product is evaluated against the same seven criteria. We don’t reduce that evaluation to a single number — instead, the criteria below are weighed together into a plain-language verdict that tells you what actually matters about the product:

• Formula and Product Quality — weighted most heavily
• Evidence and Research — weighted most heavily
• Transparency — weighted heavily
• Value for Money — weighted heavily
• 50+ Friendliness — weighted moderately
• Ease of Use — weighted moderately
• Consumer Policies — weighted moderately

Evidence and quality together carry the most weight in every review, deliberately — a product can’t earn a strong verdict purely on convenience or price. 50+ Friendliness is considered as its own category, separate from Ease of Use: Ease of Use covers day-to-day usability any adult would care about (pill size, taste, dosing frequency), while 50+ Friendliness covers what matters specifically because you’re older, or shopping for someone who is — label clarity, how simple the ordering process is, subscription-term clarity, cost predictability, and whether customer support is reachable by phone.

What never affects our verdict

Commission rate, affiliate network, or how well a product tends to convert never factor into our evaluation. We apply the same criteria the same way to every product we cover.

How often we recheck

Every review shows a Last Reviewed date and a Last Price Checked date. We recheck pricing, refund terms, and product availability periodically and update the review when something material changes. See our Evidence and Sources Policy for how we source and verify claims.
