Question 1

Do the affiliate links change what you recommend?

Accepted Answer

The pick gets decided before anyone checks whether a commission exists. We choose on ingredient panel, dose, third-party testing and price per serving, then look for an affiliate programme afterwards — which is why some of our top picks earn us nothing at all.

Where a link does pay us, it is disclosed at the top of that page, and the price you pay is identical to going direct. If a product we already recommend gets reformulated into something worse, the guide changes and the commission goes with it.

Question 2

How does something end up in one of these guides?

Accepted Answer

Every guide starts with the question a reader actually asked us, not with a product list. We map the category, work out what the research supports, and only then look at what is on the shelf. Anything that survives gets written up with its weaknesses included. A guide with no criticism in it is an advertisement, and we would rather publish a shorter list than a flattering one.

Question 3

Can a brand pay to be listed, or to score better?

Accepted Answer

No — and there is no rate card, because there is nothing to sell. Placement, ranking and verdict are not commercial products here, and no brand has ever been given a preview of a guide before it went live.

Question 4

Do you actually buy the things you write about?

Accepted Answer

Where a product can reasonably be bought and used, we buy it at retail rather than accepting a sample, so nobody is owed a favour. Where testing is impractical — a state-by-state legal map, for example — we say plainly that the guide is documentary rather than hands-on. We do not claim laboratory testing we have not run. When accuracy numbers appear in a guide, they come from published validation studies and are cited, not from our kitchen table.

Question 5

Do I need any of this to make progress?

Accepted Answer

Mostly no. The heavy lifting in metabolic health is done by the base layer — whole food, enough protein, sleep and resistance training. Sourcing guides exist to make that base layer easier to buy, not to sell you an extra layer on top. Supplements sit at the bottom of the list on purpose. For most adults they are a rounding error next to the first four rows, and research suggests the ordering below is a fair way to spend attention.

Question 6

How often are these guides reviewed?

Accepted Answer

Every guide carries a published review date at the top. Categories that move quickly — electrolytes, wearables, anything with frequent reformulation — get revisited more often than a legal reference map does. When a pick changes, the guide changes rather than quietly gaining a new number one. Laws, formulations and prices all move, so treat the review date as the real currency of the page.

Question 7

Why is there a raw-dairy legal map but no recommendation?

Accepted Answer

Because the honest answer differs by state and by person. What is legal to buy in one state is a herdshare arrangement in the next and prohibited in a third, so a blanket recommendation would be useless at best. Raw dairy also carries genuine, documented microbiological risk that is higher for pregnant people, young children, older adults and anyone immunocompromised. We map the law, explain the trade-off both ways, and leave the decision — and the conversation with your physician — where it belongs.
