The six ingredients shown in the formula section, what each one is, and the two things the brand does not tell you about them.
The formula section shows six ingredients: mangosteen, konjac fibre, prickly pear, turmeric, resveratrol and cinnamon bark.
They cover three broad jobs. Fullness comes from the konjac fibre and is the formula's clearest mechanism. Glucose and carbohydrate handling is cinnamon and prickly pear's territory. Antioxidant and anti-inflammatory activity comes from mangosteen, resveratrol and turmeric.
One of these is genuinely different from the others. Konjac glucomannan works physically rather than biochemically — it absorbs water and takes up space — which is exactly why it is the one ingredient here with regulatory acceptance behind it.
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.
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.
Each ingredient with the brand's own description alongside a fuller account, and a link to the page covering it in depth.
The brand's description: Provides antioxidant support for metabolic health.
A tropical fruit whose rind is rich in xanthones, included by the brand for antioxidant support relating to metabolic health.
Full Mangosteen page
The brand's description: Promotes fullness and appetite control.
A soluble fibre from konjac root that absorbs water and expands in the stomach. The one ingredient here with an accepted regulatory health claim behind it.
Full Konjac Fibre page
The brand's description: Helps reduce carb absorption and calorie intake.
A cactus fruit and pad extract with a modest human research record around post-meal glucose and dietary fat handling.
Full Prickly Pear page
The brand's description: Supports healthy inflammation and metabolic balance.
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: Supports cellular health and metabolic longevity.
A polyphenol from grape skins with compelling laboratory research and persistently disappointing human trials.
Full Resveratrol page
The brand's description: Supports healthy blood sugar and metabolic efficiency.
A common culinary spice with a real but genuinely contested research record around blood glucose markers.
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 3 g daily protocol. The brand's own citations include the supporting meta-analyses, which is to its credit.
Real research, contested conclusions. Cinnamon has been studied repeatedly for glucose markers, with meta-analyses reaching different conclusions. Prickly pear has a systematic review on glucose and insulin, plus work on faecal fat excretion.
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's headline citation is a mouse study. Resveratrol has twenty years of compelling laboratory work and persistently disappointing human trials, largely because it is metabolised almost immediately.
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.
Always take it with a full glass of water, and not immediately before lying down. Anyone with swallowing difficulty or a narrowing anywhere in the digestive tract should speak to a doctor first.
Consult a healthcare professional before use if you are pregnant, nursing, taking medication or managing a health condition.
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.

Every figure above is the brand's own published pricing, and the arithmetic is internally consistent on all three tiers — $79 + $10 shipping = $89, $69 × 3 + $12 = $219, $47.50 × 6 + $14 = $299. The compare-at prices are the brand's own reference figures rather than an independent valuation; see the pricing page for what they imply. The best-seller seal on the six-bottle package is the brand's own designation, not an independent ranking. Confirm the current offer at the official checkout before paying.
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.
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.
A plant-based capsule alongside the balanced eating, regular movement and decent sleep that do the real work in metabolic wellness. Six named ingredients, stimulant-free, and a 90-day money-back guarantee on every order.
