Choosing A Heart Supplement: A Nine-Point Checklist
Nine things to check on any supplement label, in the order that decides anything: amounts, chemical forms, extract ratios, the excipient list, allergens, what the seals mean, whether a certificate exists, how long the refund window is, and whether the seller can be contacted. The product this website sells passes four of them.
A method rather than a recommendation. It works on a competitor's bottle as well as on this one, which is the point.
Nine points, in the order they decide anything
Points one to five are about the label. Six and seven are about the claims around it. Eight and nine are about the seller.
1. Amounts
Is there a milligram or microgram figure beside every named ingredient?
Without it nothing can be compared to research, to a competitor or to the price.
2. Forms
Is the chemical form named, not just the nutrient?
Ubiquinone and ubiquinol are both coenzyme Q10 and behave differently. Magnesium oxide and magnesium glycinate are not interchangeable.
3. Extract ratios
For any botanical or extract, is the ratio and the standardised marker printed?
A 10:1 extract is not the same material as a powder, and a standardised marker is what makes two products comparable.
4. Other ingredients
Is the excipient list printed?
It names the capsule shell, the flow agents and anything a buyer might react to. It is legally required on the bottle, as the FDA labelling guide sets out.
5. Allergens
Is there an allergen statement?
For a large minority of buyers this is the first thing checked and the whole decision.
6. Seals
Does the product explain what its seals mean?
Seals describe processes or claims. GMP is a real audited standard; natural has no regulatory definition at all.
7. A certificate
Is a certificate of analysis available on request?
Purity and heavy metals matter most for mineral and botanical ingredients, and for shilajit specifically.
8. A refund window
Is there a money-back window long enough to test the product?
Anything in this category works over weeks if it works at all, so a 14-day window is a window designed not to be used.
9. A contactable seller
Is there a telephone number, a return address and a named desk?
A supplement seller with neither is telling you in advance how a refund will go.
Why the amount column decides everything else
If you only do one thing on this list, do this one. An ingredient list without amounts is a list of nouns, and every question a buyer actually has depends on the numbers beside them.
- ›Is this a research dose? Unanswerable without a number. Trials state doses; labels have to as well or the comparison cannot be made.
- ›Is this good value? Cost per milligram is how supplements are compared. Without amounts there is no denominator.
- ›Is this better than the cheaper one? Two bottles naming the same ingredient can differ by a factor of twenty.
- ›Could this interact with my medicine? A pharmacist will ask for the amount, and not having it makes the conversation shorter and less useful.
- ›Is the claim plausible? An ingredient at a token amount is on a label for the name rather than the effect, and it happens constantly.
A proprietary blend is a partial version of the same problem: it gives a total rather than the parts. That total is a ceiling, and it is worth using as one. If a blend is 500 mg and names twelve ingredients, no single one of them can be at a research dose unless the other eleven are traces.
A label with no amounts at all does not even give you the ceiling. Analytical work on coenzyme Q10 content in supplements exists precisely because declared content is worth verifying, and a product declaring nothing cannot be verified in either direction.
The same checklist, applied to the product this website sells
Written by the desk that sells Cardio Clear 7, which is exactly why the failures are in the table rather than in a footnote.
| Point | The question | This product | Why |
|---|---|---|---|
| 1. Amounts | Is there a milligram or microgram figure beside every named ingredient? | Fail | No amount is published for coenzyme Q10, shilajit or PQQ. |
| 2. Forms | Is the chemical form named, not just the nutrient? | Partial | The capsules are printed Co Q10 ubidecarenone, so the form is knowable even though the amount is not. |
| 3. Extract ratios | For any botanical or extract, is the ratio and the standardised marker printed? | Fail | The shilajit extract ratio and fulvic acid percentage are not published. |
| 4. Other ingredients | Is the excipient list printed? | Fail | Not published in the material this desk holds. |
| 5. Allergens | Is there an allergen statement? | Fail | Not published, which makes the gluten-free and dairy-free badges unverifiable from the label. |
| 6. Seals | Does the product explain what its seals mean? | Pass | Every badge is explained on the testing and quality page, including the ones that flatter the product least. |
| 7. A certificate | Is a certificate of analysis available on request? | Fail | Reference CAR-5447-26-CA exists. The report behind it has not been supplied and is not published. |
| 8. A refund window | Is there a money-back window long enough to test the product? | Pass | Sixty days from purchase, opened bottles included. |
| 9. A contactable seller | Is there a telephone number, a return address and a named desk? | Pass | A telephone desk on +1 (302) 200-3480, a New York return address and a named editorial desk. |
Four fails, one partial, four passes. The four fails all come from the same root cause, which is that no Supplement Facts panel is published.
Four fails, and what to do with that
Four of the nine failures on this product come from one root cause: no Supplement Facts panel is published in the material a buyer can see before ordering. Amounts, extract ratios, other ingredients and allergens are four consequences of a single omission, and all four would be fixed by one photograph.
That is worth saying because four fails out of nine sounds worse than it is, and also because it is not an excuse. A seller who wanted those four points could have them this week. Until then the honest position is that this product is bought on the strength of its named ingredients, its seller and its refund window rather than on its label, and a buyer should know which of those they are relying on.
The four passes are not nothing either. A 60-day window that includes opened bottles, a telephone desk with a person on it, a New York return address and an explanation of every seal on the bottle put this product ahead of a large part of the category on the things a buyer can verify before they order.
Use this on the next bottle you pick up. The checklist is not about this product. Take it to a pharmacy shelf, a marketplace listing or a competitor’s website and score them the same way. Two or three of the nine will sort most of the aisle in under a minute.
What a seal proves, and what a certificate reference does not
| Mark | What it means | What it does not mean |
|---|---|---|
| GMP certified | Audited process controls: cleanliness, documentation, batch records | Anything about what is in the capsule |
| FDA-registered facility | The facility is on a register and can be inspected | FDA approval. No supplement has that |
| Made in the USA | Manufacturing happened in the United States | That the ingredients were grown or mined there |
| Non-GMO | A sourcing claim about the inputs | Much, when the inputs are not common GM crops |
| Natural | Nothing. There is no regulatory definition | Anything at all |
| Doctor formulated | A manufacturer's statement about its own process | That a named, credentialled clinician can be checked |
| A certificate of analysis reference | That a certificate exists under that number | What the certificate says, unless you have read it |
The FDA introduction to supplements covers the first two rows. The last row is the one most often mistaken for evidence.
The refund window and the seller are half the decision
These two points are about the purchase rather than the product, and they are underrated. Nothing in this category produces a result you can judge in a fortnight, so a 14-day refund window is a window designed not to be used. Sixty days is the shortest one that lets a buyer actually test a product before deciding.
The seller test is simpler still. A telephone number that a person answers, a physical return address, a named desk and a published correction route. A supplement seller with none of those is telling you in advance how a refund conversation will go, and the time to notice is before the order rather than after it. NCCIH's guidance on using supplements wisely and the NIA's pages for older adults both make the same point in gentler language.
Score the label
Points one to five, in two minutes, from the back of the bottle or a listing photograph.
Score the claims
Points six and seven. Look for what the marketing says that the bottle does not.
Score the purchase
Points eight and nine. Find the refund window and the telephone number before you find the buy button.
Decide what you are relying on
A strong label, or a strong seller, or both. Knowing which changes what you should expect.
Set your own end date
Before you order. A supplement course with no decision point is a subscription you administer yourself.
Label checklist questions
What is the first thing to check on a supplement label?
The amount column. An ingredient list with no milligrams beside it cannot be compared to any research, to any competitor, or to the price.
Is a proprietary blend always bad?
Not always, but it hides the one number that matters. A blend total is a ceiling: no single ingredient in it can exceed the total, and most are far below it.
Does FDA-registered mean the FDA checked it?
No. Registration means the facility is on a list and subject to inspection. No dietary supplement is FDA-approved.
How many points should a good label pass?
Seven of the nine below is a good label. Nine is rare. Four or fewer is a product being sold on marketing rather than on content.
Every page, every journal post, the bottle facts and the ingredients go through review by Dr. Brenda McCool, ND before they ship. We write these pages from the printed Cardio Clear 7 bottle and the manufacturer’s own listing artwork, cite public research for coenzyme Q10, shilajit and PQQ, and print “not published” wherever a figure is not disclosed rather than estimating it. This label publishes no amount for any of its three ingredients, and that fact appears on every page where an ingredient is named. Where the seller’s marketing claims more than the bottle supports, we say so on the page. Corrections are made on the page itself and the review date moves forward. Write to [email protected].
