About Stack and Label

What this site is, how it makes money, and what it refuses to do.

What this site is

Stack and Label is about how supplement labels work: what a proprietary blend is permitted to withhold, what each certification mark actually verifies, why claims are phrased the way they are, and which manufacturing credentials mean anything.

The premise is that label literacy transfers. Knowing one product's rating helps with one product; being able to read a panel helps with every product you will ever pick up.

What this site does not do

We do not publish product reviews, ratings, prices or test results. Laboratory testing of finished products is expensive and specialised, and we have not done it. Inventing results, or recycling marketing claims as findings, is the exact behaviour this site exists to help you detect.

So there are no scored rankings here and no “best of” tables. Where products have genuinely been verified by someone, we point at the certifier — NSF, Informed Sport, USP — rather than claiming the credit for ourselves.

How this site makes money

Some links on this site are affiliate links. If you buy through one, we may earn a commission at no additional cost to you.

Those links go to search results for a category — certified products, for instance — rather than to a specific item we have endorsed. We are not in a position to tell you which product is best, and a link that puts a category in front of you does not pretend otherwise.

Since we do not rank or recommend individual products, there is very little for a commission to distort.

Our sister site

Stack and Label is run by the same people as The Scoop Desk, which covers supplement ingredients — effective doses, forms and what the research supports. This site covers labels: how to evaluate the product in front of you.

We mention the connection because common ownership of two sites in one subject area is the kind of thing readers are entitled to know without having to work it out.

Not medical advice

Nothing here is medical advice, and none of it substitutes for a clinician who knows your history. Supplements interact with medications and with existing conditions. If you are pregnant, breastfeeding, managing a health condition or taking prescription medication, talk to your doctor or pharmacist first.

If you are subject to drug testing, use only products with every-batch third-party certification for sport, and follow your federation's guidance over anything written here.

Corrections

Regulations change and pages age. If something here is wrong, we want to fix it — corrections are welcome and will be made.
