Ingredient hub
The MetaBurn Ingredient Hub
An entry point to all six ingredient pages, grouped by how strong the evidence behind each one actually is rather than by label order.
How the MetaBurn Formula Groups Together
Six ingredients doing three jobs. Reading them grouped by evidence tells you considerably more than taking them in the order the page lists them.
The one with regulatory acceptance
Konjac glucomannan stands apart, and not by a small margin. It is a soluble fibre that absorbs water and expands, and it carries an accepted European health claim for contributing to weight loss alongside an energy-restricted diet — at 3 g daily, in three doses, with water, before meals. The brand's own citation list includes the supporting meta-analyses.
Real research, contested conclusions
Cinnamon bark has been studied repeatedly for glucose markers, with meta-analyses that genuinely disagree with each other. Prickly pear has a systematic review on glucose and insulin plus research on faecal fat excretion — a smaller literature, but a real one.
Extensive research, absorption problem
Turmeric has one of the largest research bases of any botanical, mostly outside metabolism, and curcumin is very poorly absorbed without an enhancer the brand does not mention including.
Promising in the laboratory, thin in people
Mangosteen's headline citation is a study in high-fat-fed mice. Resveratrol has twenty years of compelling laboratory work and persistently disappointing human trials, largely because it is metabolised almost immediately after absorption.
Six ingredients are shown, not eleven
The official page opens by describing "an exclusive blend of 11 powerful ingredients including Berberine HCL, Mangosteen Powder, and breakthrough Akkermansia Muciniphila probiotics".
Its own formula section then lists six: mangosteen, konjac fibre, prickly pear, turmeric, resveratrol and cinnamon bark. Neither berberine nor any probiotic appears among them.
Five of the sixteen scientific citations at the foot of that page are also for ingredients not shown in the formula — berberine, riboflavin, alpha-lipoic acid, Akkermansia muciniphila and Bifidobacterium breve.
This website works from the six that are actually listed. If the other five matter to you, the product label is the only thing that settles it, and it is worth reading before you order.
MetaBurn does not publish its ingredient amounts
All six ingredients are named, which is useful. What is not published anywhere is how much of each one a capsule contains.
That gap matters because effect depends on amount. The konjac glucomannan research the brand itself cites used 2–4 g daily. Cinnamon trials used grams. Curcumin from turmeric is famously poorly absorbed without an enhancer. Without figures, none of it can be compared to what is actually in the bottle, so no amounts appear anywhere on this website.

05 · Cellular health
Resveratrol
A polyphenol from grape skins with compelling laboratory research and persistently disappointing human trials.

06 · Blood sugar and efficiency
Cinnamon Bark
A common culinary spice with a real but genuinely contested research record around blood glucose markers.

Research context
Reading the MetaBurn Ingredient Research
Each page below characterises its ingredient's evidence honestly, including where that evidence is thinner than the marketing implies. Two of the six get notably critical treatment, which is what the literature supports.
How to read the research on this MetaBurn page
The studies described here examined individual ingredients, usually on their own, at doses set by the researchers. That research provides scientific context for why an ingredient appears in a formula.
It does not demonstrate that the finished MetaBurn product produces the same outcomes. No clinical trial of this finished formula has been published, so nothing here should be read as product-level clinical evidence.
Returns
The MetaBurn 90-Day Guarantee
Every MetaBurn order is covered by a 90-day money-back guarantee. The brand frames it generously — no pressure, no questions asked — and 90 days is well above the 30 and 60-day windows common in this category. It is also long enough to judge a gradual daily supplement fairly, which matters.
One detail in the MetaBurn guarantee wording worth reading twice
The published terms ask you to contact the seller within 90 days of purchase and return your order to receive a refund.
That is a meaningful difference from guarantees that let you keep or discard the product. It means keeping the packaging, and it means the return postage question is worth asking before you order, since the sales page does not address who pays it.
The guarantee runs from the date of purchase. The three and six-bottle packages hold 90 and 180 days of product, so on the larger package the window closes with several bottles unopened. Note your purchase date and set a reminder for around day 80.
Refunds are handled by the seller and its retailer rather than by this website. Read the official return and refund policy at the checkout for the binding terms.
