All eight ingredients the brand names, what each one is, and the two things the source does not tell you about them.
The brand names eight ingredients: mangosteen, konjac fibre, prickly pear, turmeric, resveratrol, cinnamon bark, berberine HCL and Akkermansia muciniphila probiotics.
They cover four jobs. Fullness comes from the konjac fibre. Blood sugar steadiness is berberine and cinnamon's territory. Digestion and gut balance comes from the fibre plus the probiotic. And antioxidant support comes from mangosteen, resveratrol and turmeric.
Two stand apart from the rest on evidence. Konjac glucomannan has an accepted regulatory health claim, and berberine has the most substantial human research record in the formula. The others range from modest to largely preclinical.
The source names eight distinct ingredients across its product description: Berberine HCL, Mangosteen, Akkermansia Muciniphila probiotics, Konjac Fibre, Prickly Pear, Turmeric, Resveratrol and Cinnamon Bark.
Its numbered ingredient list, however, counts Mangosteen twice — once as "Mangosteen Powder" and again as "Mangosteen" — and leaves Cinnamon Bark out entirely, despite naming it in the product description, the how-it-works section and the benefits list.
This site works from all eight distinct ingredients. Six have supplied photography and their own detailed pages; berberine and the Akkermansia probiotic are covered on the ingredients page. The product label is the only thing that settles what is actually in the bottle, and it is worth reading before ordering.
Credit where it is due: the source does state how to take it — one capsule each morning with a full glass of water. That is more than many pages in this category bother with.
What is not published is how much of each ingredient a capsule contains. That gap matters because effect depends on amount. Konjac glucomannan's accepted health claim is tied to 3 g daily taken in three pre-meal doses. Cinnamon and berberine trials used quantities measured in grams and hundreds of milligrams. Curcumin is poorly absorbed without an enhancer. None of it can be compared to what is in the bottle, so no amounts appear anywhere on this website.
The six ingredients with supplied photography, each with the brand's own description alongside a fuller account, and a link to its detailed page.
The brand's description: Described by the brand as rich in antioxidants called xanthones that support cells, metabolism and balanced energy levels.
A tropical fruit whose rind is rich in xanthones, included for antioxidant support. Its human research record is considerably thinner than its laboratory one.
Full Mangosteen page
The brand's description: Described by the brand as a natural fibre that expands in the stomach to help you feel full and control appetite.
A soluble fibre from konjac root that absorbs water and expands. The one ingredient in this formula with an accepted regulatory health claim behind it.
Full Konjac Fibre page
The brand's description: Described by the brand as supporting healthy digestion and metabolism, and as possibly helping the body absorb fewer carbohydrates.
A cactus fruit and pad extract with a modest but genuine human research record around post-meal glucose and dietary fat handling.
Full Prickly Pear page
The brand's description: Described by the brand as containing curcumin, which helps the body manage inflammation and keep metabolism balanced.
A rhizome whose active compound curcumin is among the most studied plant compounds in nutrition — and among the most poorly absorbed.
Full Turmeric page
The brand's description: Described by the brand as a natural antioxidant from grapes and berries that supports cells, energy production and metabolism.
A polyphenol with compelling laboratory research and two decades of persistently disappointing human trials.
Full Resveratrol page
The brand's description: Named by the brand alongside berberine as helping keep blood sugar steady, so the body uses sugar more effectively.
A common culinary spice with a real but genuinely contested research record around blood glucose markers.
Full Cinnamon Bark pageBerberine HCL and the Akkermansia probiotic are named by the brand but have no supplied photography, so they are covered here rather than on dedicated pages. Both matter — one of them arguably more than anything else in the formula.
Described by the brand as a plant compound supporting healthy metabolism, balanced blood sugar and energy levels. Berberine has a substantial human research literature, notably on glucose markers, and also meaningful interaction considerations — it is the ingredient in this formula most worth raising with a pharmacist.
A probiotic the brand describes as helping keep the gut microbiome balanced, supporting digestion and nutrient absorption. Research into this species is genuinely interesting and still early, and much of it involves pasteurised preparations at specified doses.
Grouped by evidence strength, which tells you more than list order does.
The two strongest. Konjac glucomannan carries an accepted European health claim for contributing to weight loss alongside an energy-restricted diet. Berberine has multiple human meta-analyses behind its glucose effects. Neither is a marketing invention.
Promising but early. Akkermansia muciniphila has a genuinely interesting research literature connecting it to metabolic health, mostly recent and much of it using pasteurised preparations at specified doses.
Real research, contested conclusions. Cinnamon has been studied repeatedly for glucose markers with meta-analyses that disagree. Prickly pear has a systematic review on glucose and insulin plus work on dietary fat.
Extensive research, absorption problem. Turmeric's curcumin has an enormous literature, mostly outside metabolism, and is very poorly absorbed without an enhancer.
Largely preclinical. Mangosteen and resveratrol both have interesting laboratory chemistry and thin human evidence, resveratrol especially so given how quickly it is metabolised.
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.
Take it with a full glass of water — and the brand says so too. Konjac glucomannan expands dramatically on contact with liquid, which 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. Do not take it immediately before lying down, and speak to a doctor first if you have any swallowing difficulty or narrowing of the digestive tract.
Consult a healthcare professional before use if you are pregnant, nursing, taking medication or managing a health condition — advice the source gives as well.
The same formula in every package. What changes is the quantity, the per-bottle rate and whether the two bonus guides are included.
$79 total · free shipping, so the total is simply 1 × $79
$285 total · free shipping, so the total is simply 6 × $47.50
$207 total · free shipping, so the total is simply 3 × $69
The per-bottle prices and the free-shipping terms are the brand's own published figures. The package totals are not separately quoted on the source; since shipping is stated as free, they follow directly from the per-bottle rate and are shown here as arithmetic rather than as quoted prices. The best-seller seal on the six-bottle package is the brand's own designation, not an independent ranking. The source also quotes $49 and $99 per bottle elsewhere on the same page — see the pricing page for why this site uses the three-tier figures. Confirm the current offer at the official checkout before paying.
Every MetaBurn order carries a 90-day money-back guarantee running from the date of your original purchase. Ninety days is well above the 30 and 60-day windows common in this category, and it is long enough to judge a gradual daily supplement fairly.
The brand frames it generously — no pressure, no hassle, no questions — and states that refunds are issued within 48 hours.
Two conditions sit in the published terms. You must contact the seller within 90 days, by phone or email, and return your purchase. The 48-hour refund window runs from when the product is received back, not from when you ask.
That is a meaningful difference from guarantees that let you keep or discard the product. It means keeping the packaging, and it makes return postage a fair question to ask before ordering, since the source does not say who pays it.
The six-bottle package holds 180 days of product against a 90-day window, so on that tier the guarantee closes with three bottles unopened. Note your purchase date and set a reminder for around day 80.
Refunds are handled by the seller and ClickBank rather than by this website. Read the official refund policy at the checkout for the binding terms.
One capsule with a full glass of water, alongside the balanced eating, regular movement and decent sleep that do the real work in metabolic wellness. Stimulant-free, and a 90-day money-back guarantee on every order.
