Mangosteen
A tropical fruit whose rind is rich in xanthones, included by the brand for antioxidant support contributing to overall internal balance.
Full Mangosteen pageSix named plant-based ingredients. Here is what each one is, where its research sits, and the one thing the brand does not tell you.
MetaBurn combines six ingredients: mangosteen, konjac fibre (glucomannan), prickly pear, turmeric, resveratrol and cinnamon bark.
The design covers three broad areas. Fullness comes from the konjac fibre and is the formula's clearest mechanism. Glucose handling is cinnamon and prickly pear's territory. Antioxidant activity comes from mangosteen and resveratrol, with turmeric contributing to general comfort.
One of these is not like the others, and it is worth flagging. Konjac glucomannan works physically rather than metabolically — it absorbs water and takes up space. That makes it the only ingredient here whose effect does not depend on a chain of biochemical assumptions.
All six ingredients are named, which is more than many products in this category manage. What is not published anywhere is how much of each one a capsule contains — or, for that matter, how many capsules make up a daily serving. The brand's own FAQ says only to follow the directions on the product label.
That gap matters, because effect depends on amount. Konjac glucomannan's fullness research used several grams before meals. Curcumin from turmeric is famously poorly absorbed without an enhancer. Resveratrol trials typically used hundreds of milligrams. Without figures, none of it can be compared to what is actually in the bottle, so no amounts appear anywhere on this website.
"11 natural ingredients." The reference's meta description says eleven; its own page lists six, and six is what appears here. Its meta keywords also mention berberine and probiotics, neither of which is in the published formula.
Fat-burning framing. The reference's page title describes MetaBurn as a "Natural Fat-Burning Supplement". Its own body copy is far more restrained — metabolic support, energy balance, appetite awareness — and that restrained register is the accurate one, so it is the one used here.
"Without any side effects." No supplement can support that claim, and it is not repeated.
Each ingredient with its role and a link to the page covering it in depth.
A tropical fruit whose rind is rich in xanthones, included by the brand for antioxidant support contributing to overall internal balance.
Full Mangosteen page
A soluble fibre from konjac root that absorbs water and expands in the stomach, which is the basis of the formula's fullness and appetite claim.
Full Konjac Fibre page
A cactus fruit and pad extract included by the brand to support carbohydrate balance and steady metabolic activity through the day.
Full Prickly Pear page
A rhizome whose active compound curcumin is among the most studied plant compounds in nutrition, included here for overall balance and daily comfort.
Full Turmeric page
A polyphenol found in grape skins and several other plants, included for antioxidant support and cellular balance.
Full Resveratrol page
A common culinary spice with a genuine research history around glucose handling, included for balanced energy and metabolic stability.
Full Cinnamon Bark pageGrouped by evidence strength, which tells you more than list order does.
The strongest by a distance. Konjac glucomannan carries an accepted European health claim for contributing to weight loss alongside an energy-restricted diet, subject to a specific 3 g daily protocol. Very few ingredients in this category have anything comparable.
Real research, mixed conclusions. Cinnamon has been studied repeatedly for glucose markers, and meta-analyses have disagreed with each other — some finding modest benefit, others finding none. Turmeric has an extensive literature, mostly outside metabolism and hampered by poor absorption.
Smaller literatures. Prickly pear has some human work on post-meal glucose and blood lipids, but far less than cinnamon.
Largely preclinical. Mangosteen's xanthones and resveratrol both have interesting laboratory and animal research and thin human evidence. Resveratrol has the additional problem of being metabolised almost immediately after absorption.
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.
Konjac glucomannan expands dramatically on contact with liquid — that expansion is exactly how it produces fullness. Taken without enough water, it can swell in the throat or oesophagus, and there are documented cases of obstruction with glucomannan products, particularly tablet forms.
Always take it with a full glass of water, and do not take it immediately before lying down. Anyone with a history of swallowing difficulty or a narrowing anywhere in the digestive tract should speak to a doctor first.
The brand's own advice is to consult your healthcare provider before use if you have a medical condition or take medication. That is worth following rather than skimming.
The same six-ingredient formula in every package. What changes is the quantity, the per-bottle rate and whether the two bonus guides are included.

The official source publishes one price clearly: from $47.50 per bottle, against a stated regular price of $199 per bottle. What it does not publish anywhere in readable text is what each package costs in total — its pricing section is a single image that links straight through to the order page.
Rather than guess at totals by multiplying, this site shows only the figure the brand actually states. Confirm the current price, the package total and any shipping cost at the official checkout before paying.
Every MetaBurn order is backed by a 90-day money-back guarantee. The brand states that if you are not satisfied within 90 days you can request a full refund, describing the process as simple and straightforward.
Ninety days is a genuinely generous window by this category's standards, where 30 and 60-day guarantees are more common. It also happens to be long enough to give a gradual daily supplement a fair trial, which is a reasonable pairing.
Two details are not published on the sales page: whether the 90 days runs from the order date or from delivery, and who covers return postage if bottles need sending back.
Neither is unusual to omit, and neither is a reason for concern — but both are worth reading at the checkout before you pay rather than assuming.
The brand also states that every order is a one-time purchase with no automatic renewals or hidden fees, which is worth verifying at checkout as you would with any online order.
A simple capsule routine alongside the balanced eating, regular movement and decent sleep that do the real work in metabolic wellness. Six named plant-based ingredients, and a 90-day money-back guarantee on every order.
