Metavin supplement: seller and label check
Is Metavin Legit? A UK Check of the Seller, the Label and the “Metabolism” Claims
- Seller: no company trading as Metavin on Companies House, no UK retailer and no Trustpilot profile that we could find
- Label: sold as “MV·40 – everyday slim formula” for “fat burn, digestion, vitality”, but no ingredient list is published
- Claims: “metabolic support” and “fat burn” need a specific authorised claim and ingredient behind them – we found neither
- Seller unidentified
- Claims not authorised
- Food supplement only
Metavin has been advertised in the UK as a “metabolic support” supplement. That phrase sounds scientific, but UK advertising rules are strict about what it can mean. We looked at what the bottle actually says, who's behind it and which claims stand up.

- Claims not authorised'Fat burn' and 'metabolic support' need a specific authorised claim behind them
- Food supplement onlyNot MHRA licensed and not a treatment; speak to your GP about weight concerns
Legit or not? The short answer
Metavin looks like a real product with a polished brand – but almost nothing about it can be independently checked. We couldn't identify the company that sells it, find it at any UK retailer, or read an ingredient list. The “metabolic support” and “fat burn” promises aren't claims the UK rules allow on their own.
We wouldn't call it a scam on this evidence, but it's a supplement you'd be buying on trust. If you go ahead, get the seller's name and the full ingredient list before paying, avoid repeat-delivery traps and pay with a card or PayPal.

What the Metavin bottle actually says
The front label of the amber bottle reads “MV·40”, “metavin™”, “Formulated for your system”, “fat burn | digestion | vitality”, “Everyday slim formula.” and “60 caps | 30 days”, with “dietary supplement” printed vertically on the side and a round “Evidence-Based Nutrition” seal.
Two things stand out. First, it's marketed as a slimming product, not the general energy-and-wellbeing supplement the old version of this site described. Second, the seal isn't a certification from any body we could identify – it's part of the label design. The back panel with ingredients and directions is too small to read in every photo we found.
“Metabolic support”: what the UK rules allow
Metabolism isn't something you need to “fix” – it's the everyday process of turning food into energy. Under the UK's rules on nutrition and health claims, a food supplement can only refer to metabolism using wording from the GB nutrition and health claims register, and only if it contains a meaningful amount of the nutrient in question. Examples of authorised wording include “chromium contributes to normal macronutrient metabolism” and “vitamin B6 contributes to normal energy-yielding metabolism”.
General phrases like “metabolic support”, “vitality” or “formulated for your system” are only allowed when a specific authorised claim sits next to them. “Fat burn” has no authorised claim at all. Because Metavin's ingredients aren't published, we can't see any authorised claim that would back up its label.

Metavin is not a medicine or a weight-loss jab
Metavin is sold as a food supplement. It isn't licensed by the MHRA, it can't treat or prevent any medical condition, and it has nothing to do with prescription weight-loss treatments such as Wegovy or Mounjaro.
If you have concerns about your weight, energy levels or blood tests, the right first step is your GP or pharmacist – not a supplement bought from an advert. Don't stop or change any prescribed medicine because of a supplement.
What's missing – and why it matters
- An ingredient list. Without it you can't check caffeine content, allergens, or interactions with medicines.
- A named business. UK labels must give the name and address of the business responsible. We couldn't find this anywhere online.
- Independent reviews. No Trustpilot profile, no retailer reviews and no forum discussion we could find.
- Evidence. No study of the product and no explanation of what “MV·40” means.
Any one of these on its own might be an oversight. All four together mean you're relying entirely on the seller's marketing.
Metavin, “Metaven” and Metavin 40 wine additive
Some people search for “Metaven” – that's a misspelling of the same supplement. Separately, Metavin 40 is the trade name of an unrelated wine-making product (metatartaric acid) sold by a German oenology supplier. It isn't a supplement and has no connection to these capsules, so don't be confused by search results for it.
Red flags we removed from the old Metavin site
The earlier version of this website was written as if by the seller and was full of claims we couldn't verify:
- “4.8/5 stars” and “10,000+ happy customers” with no source
- “As seen in” the Daily Mail, The Guardian and Women's Health – we found no such coverage
- “Science-backed formula” and “GMP-certified manufacturing” – no evidence provided
- “Free UK delivery” and a “30-day money-back guarantee” – unconfirmed
- “40% off today only” and “stock is running low” – pressure tactics
The ASA treats invented reviews, fake urgency and unauthorised health claims as misleading advertising. If you see them on another Metavin page, be wary.

Safety without a label
Because we don't know what's in Metavin, we can't give specific safety advice. Products sold for “fat burn” often contain caffeine or guarana, green tea extract, Garcinia or apple cider vinegar. These can cause jitters, palpitations, poor sleep and stomach upset, and concentrated green tea extract has been linked to rare liver problems.
Don't take it if you're pregnant or breastfeeding, under 18, or have a heart, liver or kidney condition, and ask a pharmacist first if you take any medicine. Stop and see a doctor if you notice yellowing of the skin or eyes, or dark urine.
How to order Metavin safely
- Find the seller's name and address on the checkout page or terms – if there isn't one, think twice.
- Read the full ingredient list and check it for caffeine and anything you react to.
- Untick repeat deliveries unless you want them, and save the cancellation instructions.
- Pay by credit card or PayPal – both give you more protection than a bank transfer.
- Know your rights: the 14-day cancellation period for online orders may not apply to opened health products.
- Problems? Contact your card provider and Citizens Advice, which passes reports to Trading Standards.

Frequently asked questions
Is Metavin legit?
Metavin appears to be a real product, but we couldn't verify the company selling it, a UK retailer, an ingredient list or any independent reviews. Treat it as unproven and buy only after checking the seller and the label.
Is Metavin a scam?
We have no evidence that it's a scam. The previous version of this site, however, used fake-looking ratings, customer numbers and “as seen in” logos, which we removed. Those are common warning signs, so be cautious.
Who sells Metavin?
We couldn't find out. There is no company called Metavin on Companies House (only two dissolved companies with similar names), and the product isn't listed by UK retailers we searched. Check the trading name and address at checkout.
What does “metabolic support” mean?
Metabolism is simply the chemical processes your body uses to turn food into energy. In the UK, a supplement may only say it supports normal metabolism if it contains enough of a specific nutrient with an authorised claim, such as certain B vitamins or chromium. We couldn't confirm that Metavin contains any of these.
Will Metavin speed up my metabolism?
There's no evidence it will. No study of Metavin exists, and we couldn't verify its ingredients. Metavin is not a treatment for any medical condition; if you're worried about your weight or energy levels, speak to your GP.
What is in Metavin MV·40?
The front of the bottle says “MV·40”, “everyday slim formula”, “fat burn | digestion | vitality” and “60 caps | 30 days”. The ingredient panel isn't legible in any image we found and isn't published by retailers.
Are there Metavin reviews on Trustpilot?
We found no Trustpilot profile for Metavin as of November 2026.
Can I return Metavin?
Online purchases usually come with a 14-day right to cancel, but sealed health products can be excluded once opened. Read the seller's own refund policy before buying.
