GLP5 GLT review: what's really inside the one-a-day metabolism capsule
Does GLP5 GLT really wake up a slow metabolism?
GLP5 GLT is a one-a-day capsule with seven ingredients: guarana, apple cider vinegar extract, three amino acids, zinc and chromium. Studies give caffeine (the active part of guarana) a possible modest effect on weight, but most of the doses in the capsule are far below the ones tested, and it is not a GLP-1 medicine. A 3-month supply costs £109.95, about £1.22 a day. The refund small print is stricter than the "60-day" badge suggests: the written policy accepts returns for 14 days, on sealed packs only.
- 1 capsule a day, 30 capsules per pack
- Guarana, apple cider vinegar, amino acids, zinc and chromium
- Vegan, gluten-free and GMO-free, per the GLP5 GLT quiz page
- From £36.65 a pack in the 3-pack bundle
This review is based on the GLP5 GLT weight-loss quiz, order page, ingredient label, how-to-use page and returns policy (checked on Nov 13, 2026), the product photos shown there, and the NIH, NHS and study pages linked in the sources. Claims about results are as the seller describes them. We have not tested GLP5 GLT. How we review
Why does the weight come back after every diet?
You know the pattern. Two or three weeks of salads and early nights, the scale moves, and then life happens. A birthday, a stressful month, a holiday. By spring the weight is back, and it feels harder to shift than it was five years ago.
That feeling is exactly what GLP5 GLT is built around. Its online quiz asks your goal, age, height and weight, then gives you a "metabolic age" and a date when you could reach your target. For a 50-year-old woman at 13 stone, it showed a metabolic age of 87 and the warning "Your fat-burning rate is very low." The pitch that follows: "Lasting results come from taking GLP5 GLT, not from restrictive diets."
It's a clever hook, because it puts a number on something you already suspected. The question is whether a capsule can change that number. To answer it, you need to know what's in the bottle and what the research says about each ingredient at the dose used.
What is GLP5 GLT, and how is it supposed to work?
GLP5 GLT is a food supplement: one vegan capsule a day, 30 capsules per pack. The front of the bottle says "GLP-1 & Metabolic Support" and "Helps support natural GLP-1 activation and healthy metabolism".
The order page puts the idea in plain words: GLP5 GLT "works with your body to boost metabolism, burn fat faster, curb cravings, and balance blood sugar – for sustainable weight loss without aggressive stimulants." Each ingredient gets a job. Guarana for energy and focus, apple cider vinegar for digestion, three amino acids for metabolism, chromium for blood sugar and zinc for the immune system.
Two things are worth knowing straight away. First, the name and the GLP-1 wording on the label are about "support": none of the seven ingredients is a GLP-1 medicine like semaglutide or tirzepatide, and we found no published study of this formula on GLP-1. Second, the label lists every dose, which many weight-loss capsules don't. That's what lets you judge it, ingredient by ingredient, below.

What is in GLP5 GLT, and what do the studies say?
Here is the full label, per daily capsule, with what the independent research says at that dose. The two ingredients with the most research behind them come first.
The best summary of the evidence is the NIH Office of Dietary Supplements fact sheet on weight-loss supplements [1]. On caffeine, from added caffeine or from herbs like guarana, it lists a "possible modest effect on body weight or decreased weight gain over time", and notes that regular users build up tolerance. On chromium picolinate, it reports a review of nine trials using 200 to 1,000 mcg a day, where people lost 1.1 kg more than with a placebo, an effect the review's authors called of "debatable clinical relevance".
For apple cider vinegar, a 2018 randomised trial by Khezri and colleagues (39 adults), which GLP5 GLT cites on its ingredients page, gave people 30 mL of vinegar a day plus a calorie-cut diet for 12 weeks, and weight dropped more than with the diet alone [2]. GLP5 GLT has 100 mg of a dried extract, a very different amount.
So the honest picture is this: guarana is the ingredient most likely to do something you notice, mainly energy, and the rest are present at small, everyday-nutrition doses.
Is GLP5 GLT like Mounjaro or Wegovy?
No. The "GLP" in the name is the part that draws most people in, so it's worth being clear. Semaglutide (the medicine in Wegovy) and tirzepatide (the medicine in Mounjaro) are prescription weight-loss medicines. The NHS says that, depending on your BMI and other health conditions, you may be able to have medicines to help you lose weight, usually "prescribed alongside diet and lifestyle advice" [4].
GLP5 GLT is a different thing altogether: a food supplement you can buy without a prescription, with no GLP-1 medicine in it. Here's how the options compare for someone deciding where to start.
| Option | What it is | What the evidence says | Best for |
|---|---|---|---|
| GLP5 GLT | Food supplement, 1 capsule a day | Possible modest effect from caffeine; other doses well below the ones studied | A low-cost daily routine next to a diet |
| GLP-1 medicines (semaglutide, tirzepatide) | Prescription medicine, through a GP or clinic | Prescribed by doctors for weight loss, with diet and lifestyle advice | People whose BMI or health qualifies them |
| Diet and activity alone | Fewer calories, more movement | What the NHS recommends first, with or without medicine | Everyone, with or without the others |
What does GLP5 GLT look like?
These are the product photos from the GLP5 GLT pages. The bottle is a standard 30-capsule tub; the label claims "Weight Management Support", "Metabolic Balance" and "Appetite Control", and carries a "Clinically Tested" badge. The site doesn't say which clinical test the badge refers to, and we found no published trial of this product.
What are the pros and cons of GLP5 GLT?
Putting the label next to the research, the good points are about price and simplicity, and the weak points are about doses and small print.

What do buyers say on the GLP5 GLT site?
The order page shows six customer stories. Here are three, word for word. The page also quotes its own survey of 1,327 customers: 87% say they reached their personal goal and 94% would recommend it.

Is GLP5 GLT safe, and when should you ask a doctor first?
The zinc and chromium doses are within everyday limits; the caffeine amount isn't stated. The how-to-use page lists only one known side effect, dry mouth, in up to 1 in 1,000 users, and says it doesn't affect the contraceptive pill. The label adds the standard advice: don't exceed one capsule a day, and talk to your doctor if you're pregnant, breastfeeding, taking medicine or under medical care. These are the situations where that matters most.
| Situation | Why it matters | What to do |
|---|---|---|
| Pregnant or breastfeeding | Guarana contains caffeine, and the NHS says not to have more than 200 mg of caffeine a day in pregnancy. The label doesn't say how much caffeine one capsule gives. | Don't take it without your midwife or GP's OK. |
| Sensitive to caffeine, or heart palpitations | The NIH lists nervousness, jitteriness and a fast heartbeat as reported effects of caffeine. | Count it with your coffee and tea; skip it if you get a racing heart. |
| High blood pressure or heart medicine | GLP5 GLT's how-to-use page says it has no effect on high blood pressure, but the NIH lists a fast heartbeat among the reported effects of caffeine. | Ask your GP or pharmacist before you start. |
| Diabetes or blood sugar medicine | Chromium works alongside insulin. | Ask your doctor before adding it. |
| Already on a weight-loss medicine | GLP-1 medicines are prescribed with a plan. | Tell the clinician who prescribes it before adding any supplement. |
| Taking another zinc supplement | The NHS says no more than 25 mg of zinc supplements a day; GLP5 GLT has 15 mg. | Check the total across everything you take. |
| Under 18 | The label says children should only use it on a doctor's advice. | Not for teenagers without medical advice. |
Is GLP5 GLT right for you, or should you skip it?
Buy GLP5 GLT if:
- You want a simple, low-cost daily capsule to go with eating better and moving more.
- You like a gentle caffeine lift and know you handle caffeine well.
- You prefer a supplement with a full label over one that hides its doses.
- You're happy to start with one pack and judge it by how you feel, knowing the written policy only takes back sealed packs within 14 days of delivery.
Skip GLP5 GLT if:
- You're hoping for the effect of a GLP-1 medicine. Speak to your GP about whether you qualify for one.
- You're pregnant, breastfeeding or sensitive to caffeine.
- You want a capsule with doses that match the clinical trials. This one doesn't.
- You need a long, no-questions refund. The returns page is strict.
How much does GLP5 GLT cost, and which pack should you pick?
One pack costs £55 plus £4.95 delivery, £59.95 in total. Two packs cost £82.95 (about £41.48 each) and three cost £109.95 (about £36.65 each, roughly £1.22 a day), both with free delivery. The order page marks the 3-pack as the best seller and shows one pack crossed out at £79.95, and the bundle packs crossed out at £69.95 each.
Which one to pick: the 3-pack is the cheapest per day (£1.22). But given the strict returns policy below, the safer move for a first try is one pack, then the bigger bundle once you know it suits you.
3 packs, 90 days
£109.95 (about £36.65 a pack)
About £1.22 a day; free delivery.
Can you get your money back if GLP5 GLT doesn't work for you?
Only in a narrow window, and this is the part to read twice. The order page shows a "60-Day Money-Back Guarantee" badge. The returns policy, on the same site, says something stricter:
- You can return goods "within 14 calendar days of receipt".
- Items must be "sealed, unopened, unused" and fit for resale.
- You must email customer service before sending anything back.
- "Return postage costs incurred by the customer are non-refundable."
- Refunds are paid within 14 days of the return arriving.
In practice, an opened pack isn't covered by the written policy, and the 14 days run from the day the parcel arrives. That's why one pack is the safer first order: if you buy three, only the unopened ones can go back, and only within those 14 days. If the "60-day" promise matters to you, email support before ordering and ask how it works with an opened pack.
Delivery: orders usually go out the same day, the site says 2 to 3 working days, and the checkout shows the cost for your address.
Read the returns terms on the official site before you choose a pack.
Is GLP5 GLT legit or a scam?
GLP5 GLT is a real product with a published label, prices, a contact email and a returns address, and the returns page says your card isn't charged until the order is dispatched. That's a good sign.
What we couldn't check: the Trustpilot page for the shop asked for a verification check when we tried it on Nov 13, 2026, so there's no score we can share yet. The 87% and 94% survey figures come from the maker's own customer research, not an independent study.
So it isn't a scam in the sense of a fake product. The real risks are expecting a GLP-1 effect it can't give, and assuming the 60-day badge covers an opened pack. Avoid both and it's a fair, inexpensive thing to try.
Order only through the official site so its returns terms apply.

So, is GLP5 GLT worth it?
It can be, if you see it for what it is: an inexpensive, simple one-a-day capsule with a little caffeine, chromium and zinc, to go with eating better, not a GLP-1 medicine. Start with one pack rather than three, since sealed packs can only go back within 14 days of delivery, and if you want a medical option, ask your GP.
