Burntide Official Website › Choosing A Metabolism Gummy
How To Choose A Metabolism Gummy
Eight questions worth asking about any metabolism or ACV gummy before you buy one: whether it prints its amounts, whether those amounts are near the research, what the serving really is, whether a stimulant is doing the work, what it adds to your day, who is selling it, how long the refund window runs, and whether a lot has been assayed.
A checklist that works on any product in the category, then the same checklist applied to this one, with three failures in it.
Why this category needs a checklist
This category is unusually hard to shop in. Everything looks the same, the claims are legally required to be vague, and the one number that would separate two products is frequently the one neither prints. So the useful move is not to compare marketing. It is to carry the same eight questions to every product and see which ones can answer.
The checklist below is written to be used on a competitor as easily as on the product this website sells. Each point explains why it matters, and then states how Burntide scores on it. Three of the eight are failures, and they are the first two and the last, which are arguably the three that matter most.
Use this on anything. Open a competing product's label in another tab and work down the same eight. A product that passes six of eight is doing well by the standards of this category, which is itself worth knowing before you spend anything.
The eight questions
Does it print the amount of every active?
A panel that gives one number for four ingredients has told you the ceiling and nothing else. Individual amounts are the difference between a formula and a list of words. The labelling rules permit a blend, which is exactly why the products that disclose anyway are telling you something about themselves.
Burntide on this point: Fail. One blend total at 525 mg. No individual amount anywhere.
Is the amount in the same region as the research?
This is the question that decides whether the citations on a sales page mean anything. Find the dose in the study, find the dose on the label, and put them side by side. If the label cannot be compared because of point one, that is your answer.
Burntide on this point: Fail. The whole blend is smaller than the acetic acid in one tablespoon of vinegar, and twenty to fifty times below any ketone trial.
Does the serving size match what you are being quoted?
A jar of 30 at two gummies a day is fifteen days, not thirty. Check servings per container against the serving size before comparing any two products on price.
Burntide on this point: Pass. One gummy per serving, thirty servings per jar, printed plainly.
Is there a stimulant hiding in it?
Caffeine, green tea extract and synephrine all produce a sensation that people read as the product working. If a metabolism product makes you feel something in week one, that is usually what it is.
Burntide on this point: Pass. No stimulant on the panel or in the other-ingredients line.
What does it add that you are not counting?
Gummies carry sugar. Ketone salts carry minerals, sodium in particular. Both are usually small and both belong in the decision if you are counting either. The CDC has the sodium context.
Burntide on this point: Pass. 2 g sugars and 8 calories per gummy; sodium 2.5 mg, which is 0% of the Daily Value.
Is there a seller you can identify and telephone?
This is worth more than any seal. A named company, a physical address, a telephone number that a person answers, and a returns address. The FDA's list of tainted products is largely populated from channels where none of those exist.
Burntide on this point: Pass. Named desk, two New York addresses, a telephone number and a separate returns address, all printed on every page.
Is the refund window longer than the time the product needs?
A 30-day guarantee on a product that takes six weeks to judge is decorative. Work out the reported time to any change, then check the window against it.
Burntide on this point: Pass. 60 days, against a reported wait of 3–6 weeks.
Is there a certificate of analysis for the lot?
The only document that turns a printed label into a measurement. Ask for it. The answer, including a refusal or a silence, tells you a great deal.
Burntide on this point: Fail. None supplied. The certificate reference on record is a traceability reference rather than an assay.
The score for Burntide
| # | Question | Burntide |
|---|---|---|
| 1 | Does it print the amount of every active? | Fail |
| 2 | Is the amount in the same region as the research? | Fail |
| 3 | Does the serving size match what you are being quoted? | Pass |
| 4 | Is there a stimulant hiding in it? | Pass |
| 5 | What does it add that you are not counting? | Pass |
| 6 | Is there a seller you can identify and telephone? | Pass |
| 7 | Is the refund window longer than the time the product needs? | Pass |
| 8 | Is there a certificate of analysis for the lot? | Fail |
| Score | 5 of 8 |
Five out of eight, and the three failures are the ones about dose and about analysis. That is a fair summary of this product: the commercial and logistical half is strong, and the evidentiary half is what it is for almost everything in the category.
It is also a score this desk publishes on its own website, which is the only reason it is worth anything to you. A checklist that gave the product eight out of eight would tell you only that the checklist was written backwards from the answer.
Four more things worth watching
Four more things are worth knowing and did not make the eight, because they are softer or because they only apply sometimes.
Watch the comparison price
A crossed-out “was” figure is a comparison to a list price, not to a recent selling price. Treat it as marketing rather than as a saving. This website prints no price at all, which sidesteps the question.
Watch the bonus stack
Digital guides with dollar values attached are the oldest device in this category. The values are set by the seller and mean nothing. This site describes the manufacturer's guides without attaching a price to any of them.
Watch the countdown timer
If a page has one, refresh it. If it starts again, you have learned something about the page rather than about the product.
Watch the review page shape
Eight glowing reviews with the same sentence structure is the signature of a fabricated page. So is a five-star average with no star breakdown. What a real one looks like.
The three places this checklist leads
Run the eight and you will end up in one of three places. All three are legitimate outcomes and only one of them involves buying anything.
You buy nothing
The most common outcome of taking this category seriously, and the one the ODS weight-management fact sheet quietly supports. Food, sleep and movement are unglamorous and they are what the evidence is actually about.
You buy the ingredient rather than the product
If dose is what you want, a supermarket bottle of vinegar delivers the trial amount for a fraction of any supplement price. The vinegar guide works through it.
You buy a product for the routine
A defensible reason, provided you know that is what you are buying. A daily prompt attached to a meal, a printed label, and a refund window long enough to find out.
Whichever of the three you land on, the thing that makes it a decision rather than a purchase is having written down what you are testing and how you will know. MedlinePlus and the National Institute on Aging both have short, readable pages on that, and neither of them is selling anything either.

Every page, every journal post, the bottle facts and the ingredients go through review by Dr. Spencer Berry, MD before they ship. We write these pages from the Burntide label, the Supplement Facts panel photographed on the jar, and the distributor’s own paperwork. We cite public research for apple cider vinegar and beta-hydroxybutyrate, and we print “not published” wherever the label withholds a figure rather than estimating it. Where the manufacturer’s own listing artwork claims more than the panel supports, we say so on the page. Corrections are made on the page itself and the review date moves forward.
