Just one Pack in my coffee, every day for three weeks. My jeans are noticeably looser and that's the only thing I changed. I'm still kind of amazed it worked.

Slimqa is a powder sachet you stir into a drink. It combines plant extracts, L-carnitine and fibre. This page walks through what the research says about every ingredient, how to use it safely, and who should skip it, so you can decide with confidence.
Always read the label. Use only as directed. If symptoms persist, talk to your health professional. Slimqa is not a substitute for a healthy lifestyle. See the AUST L number on the box side.

No powder replaces food, movement and sleep. Research on the individual ingredients in products like this shows small and sometimes inconsistent effects. Slimqa is best thought of as a convenient daily habit: a way to add fibre and a morning ritual alongside a reduced-energy diet and regular activity. It is not a shortcut, and it will not suit everyone.
Here is one honest line per ingredient. The full evidence review follows in the ingredients section below.
Slimqa Slim Coffee Booster is a powder sachet (a "pack") that you stir into a drink. Each box holds 30 sachets and has a net weight of 60g, so every sachet is about 2g. The blend combines plant extracts, L-carnitine and two types of fibre.
It is sold direct to Australians through slimqa.au. The formula uses ingredients derived from natural sources and is produced in an EU manufacturing facility, without harmful additives. It contains no added sugar, and the box is clearly labelled as a food supplement.
The label wording reads "supports fat burning*, boosts metabolism*, sustained energy*". The asterisk matters: these statements describe what the ingredients are traditionally used for and should be read alongside a reduced-energy diet and exercise. Slimqa is presented here as one option among many. The biggest drivers of a healthy weight remain what you eat, how you move, how you sleep and how you manage stress.
We built this page as an educational guide first. If you read it and decide a different approach suits you better, that is a perfectly good outcome.

Just one Pack in my coffee, every day for three weeks. My jeans are noticeably looser and that's the only thing I changed. I'm still kind of amazed it worked.

I used to hit a wall every afternoon and need a candy bar just to push through. That craving is gone now, and my energy holds steady the whole day.

All I do is stir it into my coffee each morning. Six weeks later, I'm 5 kg lighter and I never counted a single calorie. Hands-down the easiest thing I've tried.

I was skeptical at first, but Slimqa truly works. The weight has been coming off steadily, and I've never felt better.

I've tried so many things before, so I didn't have high expectations. With Slimqa, I've stayed consistent without completely changing my lifestyle, and I'm really happy with how things are going.

I wasn't sure what to expect, but Slimqa has been so easy to fit into my routine. I've been seeing steady progress, and I feel more confident and motivated than I have in a long time.

The NHMRC Australian Dietary Guidelines emphasise variety: plenty of vegetables and legumes, fruit, wholegrain cereals, lean protein, reduced-fat dairy and healthy fats, with limited intake of foods high in saturated fat, added sugar and salt. None of this is glamorous, but it is the foundation that every other tool sits on.
A modest loss of 5–10% of body weight can improve blood pressure, blood fats, joint comfort, sleep and energy for many people. Small, sustainable changes usually outlast short bursts of strict dieting. A pace of around 0.25–0.5kg per week is commonly suggested by health professionals, and plateaus are normal.
BMI is a quick screening tool, not a verdict on your health. It cannot tell muscle from fat or show where fat sits. Waist measurement adds context: for many adults, health risk rises above about 94cm for men and 80cm for women, and more steeply above 102cm and 88cm.
See a GP or accredited practising dietitian if you have a medical condition, take regular medicines, are planning pregnancy, have struggled with disordered eating, or simply want a personalised plan. Many Australians are eligible for Medicare-supported chronic condition management and allied health visits through their GP.
Understanding the basics makes every food choice easier. This section explains the body's own systems, without any product claims.
Hunger is coordinated by the brain, gut and fat tissue. Ghrelin, produced mainly by the stomach, rises before meals. Gut hormones such as GLP-1 and PYY rise after eating and tell the brain that you have had enough. Stretch receptors in the stomach add a mechanical signal, which is one reason bulky, high-fibre, high-water foods feel satisfying.
These signals take about 20 minutes to register. Eating slowly, sitting at a table and putting down your fork between bites gives them time to work.
When you eat carbohydrate, blood glucose rises and the pancreas releases insulin to move it into cells. Refined carbohydrates on an empty stomach, like a pastry with a sweet latte, can lift glucose quickly and be followed by a dip that feels like tiredness and a craving for more.
Pairing carbohydrate with protein, fibre and healthy fat slows this curve. This is why a wholegrain toast with eggs tends to carry you further than a plain croissant.
Soluble fibre forms a gel in the gut that slows the absorption of sugar and fat. Insoluble fibre adds bulk and helps regularity. Fermentable fibres such as resistant dextrin feed beneficial gut bacteria, which produce short-chain fatty acids linked with gut health.
Exact amounts per sachet are printed on the Supplement Facts panel on the back of the box. The table below summarises what published research says about each ingredient.
| Ingredient | Role in the blend | What research suggests | Verdict |
|---|---|---|---|
| Green tea extract | Plant polyphenols (EGCG) and caffeine | Meta-analyses (Jurgens 2012, Cochrane) found very small weight differences. The TGA notes rare liver injury with concentrated extracts. | Small effect, caution |
| Green coffee bean extract | Chlorogenic acids | Onakpoya 2011 found small reductions in short, low-quality trials. | Weak evidence |
| White kidney bean extract | Starch-digestion enzyme inhibitor | Onakpoya 2011 reported a small, non-robust difference. | Limited |
| Mulberry leaf extract | Plant compounds studied for glucose handling | Small trials look at post-meal glucose. Evidence for weight loss is lacking. | Unproven for weight |
| L-carnitine L-tartrate | Amino-acid derivative involved in fat metabolism | Pooyandjoo 2016 found roughly 1.3kg greater average loss across trials. | Modest |
| Resistant dextrin | Soluble, fermentable fibre | May support fullness, stool regularity and gut bacteria. | Plausible |
| Psyllium husk powder | Bulk-forming soluble fibre | Well supported for regularity and cholesterol. Needs plenty of water. | Good for fibre |
Green tea extract provides catechins, mainly EGCG, along with caffeine. Laboratory work suggests catechins may modestly raise energy expenditure. In people, however, systematic reviews including a Cochrane review and the Jurgens 2012 analysis found differences of well under a kilogram over several months.
Safety is the key point. Rare cases of liver injury have been reported with high-dose, concentrated green tea extracts, usually taken on an empty stomach. Take Slimqa as directed, with food or a drink, and stop if you develop unusual fatigue, dark urine or yellowing of the skin or eyes.
Green coffee beans are unroasted, so they retain more chlorogenic acid, which is largely lost in roasting. Onakpoya and colleagues (2011) pooled several small trials and found a small weight difference, but they judged the trials to be of poor methodological quality.
It also contributes some caffeine. Treat it as a possible minor contributor, not a driver of change.
White kidney bean extract is often described as a "starch blocker" because it inhibits alpha-amylase, an enzyme that breaks down starch. A pooled analysis found a small, statistically borderline difference. Real-world effects depend on how much starch is in the meal.
Unabsorbed carbohydrate can ferment in the colon and cause wind or loose stools in some people.
Mulberry leaf contains 1-deoxynojirimycin (DNJ), which slows some carbohydrate-digesting enzymes. Small human studies have measured lower post-meal glucose rises. That is interesting for blood-sugar-friendly eating but is not evidence of weight loss.
If you take glucose-lowering medicines, speak to your doctor before using any product containing it.
Your body makes L-carnitine to transport fatty acids into mitochondria. Pooyandjoo and colleagues (2016) reviewed 9 randomised trials and found an average of about 1.3kg more weight lost with supplementation. The effect was small and varied between studies.
These are the quiet workhorses of the blend. Psyllium swells with water and is well established for regularity and for lowering LDL cholesterol. Resistant dextrin resists digestion and ferments in the large intestine. Together they add roughly the fibre of a small serve of vegetables, which helps fill the gap in most Australian diets.
Mix one sachet into about 200mL of coffee, tea or water.
Stir well until dissolved and drink promptly, ideally in the morning.
Follow with a full glass of water (about 250mL).
Limit yourself to one sachet per day and pair it with a reduced-energy diet and exercise.
Always follow the directions printed on your box if they differ from this summary.
Psyllium and dextrin absorb fluid. Without enough water, fibre can cause bloating, cramps or, rarely, a blockage. Drink a full glass of water with each sachet and keep up your usual fluids across the day, roughly 2 litres for most adults.
Yes. Slimqa is designed for coffee. Let a very hot drink cool for a minute, stir thoroughly and drink soon after mixing, because psyllium thickens as it sits. Iced coffee, tea and plain water also work.
Skip added sugar syrups where you can. A teaspoon of sugar adds about 80kJ, and flavoured café drinks can add far more.
Caffeine is the world's most widely used stimulant, and for most healthy adults moderate intake is fine. Slimqa contains caffeine from its green tea and green coffee extracts, and the amount per sachet is shown on the Supplement Facts panel. Because you will likely also drink coffee, it helps to know your total.
Health authorities generally regard up to about 400mg a day as safe for healthy adults. That is roughly three to four regular coffees. Pregnant and breastfeeding women are commonly advised to stay under 200mg, and children and teens should have less.
Racing heart, jitteriness, headaches, upset stomach, anxiety and poor sleep are common signals. Caffeine has a half-life of around five hours, so an afternoon dose can still affect bedtime. Consider having Slimqa before midday and cutting back on other caffeinated drinks if needed.
Plant extracts and fibre can interact with medicines. Fibre may slow the absorption of some tablets. Caffeine can interact with certain antidepressants, stimulants and heart medicines. Green tea extract has been linked to liver injury in rare cases.
Stop use and see a doctor if you notice dark urine, yellow skin or eyes, severe stomach pain, palpitations, difficulty swallowing or any allergic reaction. For poisoning concerns call the Poisons Information Centre on 13 11 26, or 000 in an emergency.
Read the full warning statements printed on the box before first use.
Supplements work best as part of a pattern. This sample day is a starting point, not a prescription. Adjust portions to your needs, preferences and medical advice.
Glass of water on waking. Slimqa stirred into your coffee, followed by a full glass of water. Breakfast with protein: eggs on wholegrain toast, or Greek yoghurt with oats and berries.
Short walk or stretch break. A piece of fruit and a small handful of nuts if hungry.
Half the plate vegetables, a quarter lean protein, a quarter wholegrain or legumes. Ten-minute walk afterwards.
Move for 30 minutes: brisk walk, swim, cycle or strength session. Switch to herbal tea after midday.
Balanced dinner with plenty of vegetables, then screens off an hour before bed to protect sleep.
From a quiet morning coffee to an iced drink on the go, a sachet fits easily into the day.

Images show everyday use of the product and do not represent results or typical outcomes.
Fact: The most generous trials show effects of a kilogram or two. A single takeaway meal can contain more kilojoules than a sachet could ever offset.
Fact: Plant extracts are active compounds. Green tea extract, for example, has rare reported liver effects, and fibre can affect how medicines are absorbed.
Fact: Exceeding the directed dose raises caffeine and fibre intake without proven extra benefit. One sachet a day is the directed amount.
Fact: Fat is lost across the body according to genetics and hormones. Strength training and balanced eating shape overall composition.
Fact: Moderate coffee contributes to daily fluid intake. Still, take extra water with fibre.
No single approach is right for everyone. Many people combine several. Here is how the main options compare.
| Approach | Pros | Cons | Typical cost |
|---|---|---|---|
| Dietary changes & activity | Strongest evidence; benefits beyond weight; no side effects from the approach itself | Takes time, planning and habit change | Low; dietitian visits vary, some Medicare-supported |
| Supplements (such as Slimqa) | Convenient daily ritual; adds fibre; no prescription needed | Small or uncertain effects; possible interactions | $23.99–$35.99 per box |
| Prescription options (via GP) | Clinically studied and medically supervised | Side effects; not suitable for everyone; ongoing cost | Varies; ask your GP or pharmacist |
| Structured programs | Accountability and community | Fees; quality varies | Weekly or monthly subscription |
After reviewing the evidence, our editorial view is balanced. Slimqa is a reasonable, low-cost add-on for adults who already drink coffee, want an easy daily routine and are committed to eating well and moving more. It is a poor choice for anyone expecting it to do the work on its own, and it should be avoided by the groups listed in the safety section.
Whatever you choose, set a review point at 4–6 weeks. Track your waist, energy and sleep. If you are not seeing a benefit or you have side effects, stop and discuss alternatives with your health professional.
