Thankfully, there are some quality appetite suppressants to cool the urge. Here are the very best appetite suppressants in the UK today, and what’s packed inside each capsule.

These are some of the best options out there to help you curb those cravings and keep your metabolism firing optimally, giving you a perfect boost in your weight loss efforts whilst keeping you energised and alert.

We all know how hard it can be to resist the temptation of our favourite snacks. They often seem to just call out to us. We also know how hard it can be to stick to a calorie-restricted diet. Hunger pangs kick in and satiation is only ever elusive.

This is where appetite suppressing supplements come into play. These little wonders will help you take control of your cravings and keep you on track with your weight loss goals.

The options I want to look at are more than simple appetite suppressants, however. They are also potent thermogenic fat burners – think of them as something like a turbo boost for your metabolism, turning up the heat and enabling your body to burn fat as you want it to.

It’s a powerful combination – helping you to eat within your diet’s limits whilst also priming your body for weight loss.

TLDR: Our No.1 Appetite Suppressant

Capsiplex Trim bottle

I would go for Capsiplex Trim – it is a standout choice for weight loss.

With its blend of natural ingredients like capsicum extract, caffeine, and black pepper extract, Capsiplex Trim activates thermogenesis, boosts metabolism, suppresses appetite, and enhances exercise performance. Its natural and safe ingredients make it a reliable choice for those seeking weight loss support. And its ability to turn down hunger pangs and keep you feeling fuller for longer is beyond great.

We’re onto something really special, here.

Our Top Appetite Suppressants

With so many options available on the market, it can be overwhelming to choose the right appetite suppressant for your needs.

To help you narrow down your options, we’ve compiled a list of our top appetite suppressants, based on ingredients, effectiveness, customer reviews, and our own personal experience. These really are some of the best weight loss supplements out there.

Capsiplex Trim

Capsiplex Trim bottle

Capsiplex Trim is a highly effective appetite suppressant and fat burner that has received positive reviews for its powerful ingredients and potential benefits for those seeking to enhance their weight loss journey. It’s targeted at women, which I think is a little erroneous – it’s a disservice to the formula. In reality, it should work incredibly well for all comers.

One of the main ingredients in Capsiplex Trim is Capsimax, an extract derived from cayenne pepper. Cayenne pepper is known for its thermogenic properties, which can increase body temperature and boost metabolism. Capsimax may also contribute to appetite suppression.

Clinical research suggests that capsicum extract, the active compound in cayenne pepper, can accelerate metabolism and promote fat oxidation. By incorporating Capsimax into its formula, Capsiplex Trim aims to harness these thermogenic properties to support weight loss efforts.

Then there is InnoSlim, a wonder ingredient made from a blend of Panax notoginseng and Astragalus membranaceus. In a clinical study, InnoSlim was found to enhance fat breakdown, reduce fat accumulation, and improve insulin sensitivity.

InnoSlim should then have a positive impact on body composition and glucose metabolism, making it a valuable addition to Capsiplex Trim.

Capsiplex Trim capsules in hand with bottle

You also get a healthy serving of caffeine in Capsiplex Trim, included to heighten thermogenesis, increase energy levels, and enhance workout performance. Caffeine is a well-known stimulant that can improve alertness and exercise performance.

It has also been shown to enhance fat oxidation and increase metabolism. By incorporating caffeine, Capsiplex Trim aims to provide an energy boost to help individuals maximise their workouts.

We’re largely (though not exclusively) looking at Capsiplex Trim’s chromium content for appetite suppression. It should help in managing blood sugar levels and reducing cravings. This can be incredibly beneficial for those struggling with emotional eating or difficulties in controlling their appetite.

Capsiplex Trim also contains glucomannan, however, one of the best appetite-suppressing ingredients going. Glucomannan works by absorbing water and expanding in the stomach, creating a sense of fullness. This can help reduce hunger and prevent overeating by promoting feelings of satiety.

Capsiplex Trim is a fantastic offering that, like many on this list, should serve the job of two supplements, ably suppressing your appetite whilst also kicking your metabolism up a gear.

PhenQ is a popular dietary supplement known for its multi-action formula and potential benefits for weight loss. It contains a combination of ingredients that, according to the manufacturer, work together to target various aspects of weight management.

PhenQ capsules from bottle

PhenQ also incorporates an array of ingredients that work together to suppress appetite. One of the key components is α-Lacys Reset, a patented blend of alpha-lipoic acid and cysteine.

Research suggests that α-Lacys Reset can boost metabolism and increase thermogenesis, resulting in higher calorie expenditure throughout the day. Additionally, it may possess antioxidant properties that could help reduce oxidative stress in the body.

The Capsimax powder in PhenQ combines various substances including capsicum, piperine, caffeine, and niacin. Capsicum, sourced from cayenne pepper, has thermogenic properties that can raise body temperature and enhance metabolism.

Piperine, derived from black pepper, has been found to enhance the absorption of other compounds and may contribute to fat metabolism. Caffeine, a well-known stimulant, can increase energy levels and improve mental focus. Niacin, or vitamin B3, plays a role in various metabolic processes and aids in the conversion of food into energy.

In addition to these, PhenQ contains some perfect appetite-suppressing ingredients, including the likes of chromium picolinate. Chromium picolinate has been studied for its potential to regulate blood sugar levels and reduce cravings, as we have seen – this can help to control appetite.

It also contains nopal, a cactus extract rich in fibre (specifically glucomannan), which as we have seen is notable for its ability to promote feelings of satiety and reduce your appetite.

Through the combination of these ingredients, PhenQ aims to provide comprehensive appetite suppression. By targeting multiple mechanisms in the body, such as increasing metabolism, promoting thermogenesis, regulating blood sugar levels, and promoting satiety, PhenQ supports weight loss efforts holistically by helping to control cravings and reduce overall calorie intake whilst also optimising your metabolic function.

PhenQ is great – it aids your weight loss efforts from several angles, along several pathways.

From the thermogenic and metabolism-boosting effects of α-Lacys Reset and Capsimax powder to the appetite-suppressing properties of chromium picolinate and Nopal extract, PhenQ aims to provide a genuinely comprehensive approach to weight management.

Hunter Burn

Hunter Burn is a premium fat burner made by Roar Ambition, one of my favourite supplement companies. It is designed to help you to lose weight and achieve a lean physique.

It is specifically marketed towards active men who are looking to enhance their weight loss efforts and optimize their fitness goals. However, as with the offerings aimed solely at women, this is all rubbish – anyone can benefit from using it.

Hunter burn capsules and bottle

One of the key ingredients in Hunter Burn is konjac root extract. Konjac root is rich in glucomannan, that lovely soluble fibre that we keep seeing – the one that has been shown to promote feelings of fullness, reduce appetite, and support healthy weight management.

It can aid in portion control and reduce the likelihood of overeating, contributing to caloric deficit and weight loss.

Another important ingredient in Hunter Burn is cayenne pepper. As we have seen, cayenne pepper contains capsaicin, a compound that can increase thermogenesis and boost metabolism. By raising body temperature, cayenne pepper may enhance calorie burning, potentially supporting weight loss efforts.

Hunter Burn also includes matcha green tea, which is a lovely touch. It is known for its high content of antioxidants and catechins, particularly Epigallocatechin gallate (EGCG). EGCG has been shown to increase fat oxidation, boost metabolism, and support overall weight management, whilst also suppressing the appetite – much like you would get from green tea extract (see above).

Additionally, Hunter Burn contains L-theanine, an amino acid commonly found in green tea. L-theanine is commonly found in nootropic supplements, where it has been shown to promote relaxation, reduce stress, and improve mood.

It works synergistically with the caffeine in the formula to provide a sustained and focused energy boost without the jitters. It should also keep anxiety down, which will make it far easier to avoid emotional eating – many people’s Achilles heel in dieting, me included.

Other ingredients in Hunter Burn include white kidney bean extract, which may inhibit the breakdown of carbohydrates and help control blood sugar levels, and Vitamin D3, which is essential for overall health and well-being.

Hunter Burn is great – a premium fat burner specifically targeted towards active men, which nevertheless should work for all dieters.

With its blend of konjac root extract, cayenne pepper, green tea, and other key ingredients, Hunter Burn aims to support weight loss efforts by reducing appetite, boosting metabolism, and providing sustained energy, whilst also suppressing your appetite, making it far easier to undereat.

Trimtone is a popular weight loss supplement. Again, this is one that is specifically (and, I argue, erroneously) designed for women. Nonsense. It should work brilliantly for everyone.

Its unique blend of ingredients are formulated to support fat burning and boost metabolism to aid in weight loss efforts, all working across the board for all dieters.

Caffeine anhydrous is one of the key ingredients in Trimtone. As we know, caffeine is a well-known stimulant that can increase energy levels, improve focus, and enhance exercise performance.

It has also been shown to stimulate thermogenesis and boost metabolism, potentially increasing the number of calories burned throughout the day, whilst acting as a mild appetite suppressant.

One of the primary mechanisms through which Trimtone suppresses appetite is by increasing feelings of satiety. The supplement contains glucomannan, which we have already seen.

Trimtone capsules with bottle and glass of water

Then there is green coffee bean extract, another important ingredient in Trimtone. Green coffee beans are unroasted coffee beans that contain chlorogenic acid, a compound known for its potential effects on weight loss. Research suggests that chlorogenic acid may help to reduce fat absorption and boost fat metabolism, ultimately contributing to weight loss.

Trimtone also includes Grains of Paradise, which is a spice derived from the ginger family. Grains of Paradise contains a compound called 6-Paradol, which has been shown to have thermogenic properties. It can increase energy expenditure and induce the conversion of white adipose tissue (fat) to brown adipose tissue, which is considered to be far more metabolically active.

It’s also worth talking about green tea extract. Green tea is known for its antioxidant properties and is often included in weight loss supplements. It may help boost metabolism and increase fat oxidation, potentially aiding in weight loss.

Green tea extract also contains compounds known as catechins, including epigallocatechin gallate (EGCG). EGCG has been studied for its potential in promoting weight loss and appetite suppression. It may influence the activity of enzymes involved in fat metabolism and promote thermogenesis, the process by which the body generates heat and burns calories.

By increasing thermogenesis, Trimtone may contribute to the suppression of appetite and the promotion of weight loss.

With its blend of caffeine, green coffee bean extract, grains of paradise, and green tea extract, Trimtone aims to support fat burning, boost metabolism, and aid in weight loss efforts. It does so masterfully, for anyone, regardless of gender.

PrimeShred is a fat burner that includes brain-boosting nootropics, making it perfect for those looking to stay switched on even during an energy deficit (i.e. a calorie deficit).

PrimeShred is at heart still a potent fat burner, though. It contains a powerful blend of ingredients that work synergistically to enhance fat burning, boost energy levels, and support overall metabolism. And, of course, it helps to sate your appetite, suppressing it to allow for a far more easily achieved calorie deficit.

One of the key ingredients in PrimeShred is green tea extract, which we’ve seen plenty of in this list. As we have also seen, green tea is rich in antioxidants called catechins, particularly Epigallocatechin gallate (EGCG).

Prime shred label

EGCG has been shown to boost metabolism and increase fat oxidation, potentially aiding in weight loss. Green tea extract may also help improve insulin sensitivity and reduce the storage of fat, whilst also suppressing your appetite incredibly effectively.

PrimeShred also contains a good dose of L-tyrosine, which is where we get the bulk of our nootropic benefits from (caffeine aside).

L-tyrosine is an amino acid that plays a crucial role in the production of neurotransmitters like dopamine and adrenaline. It can help improve focus, enhance cognitive function, and increase energy levels, making it particularly beneficial to those following a calorie-restricted diet or engaging in intense workouts.

Caffeine anhydrous is another key component of PrimeShred. Caffeine is a well-known stimulant that can increase energy levels, improve mental alertness, and enhance exercise performance. It also has thermogenic properties, which can boost metabolism and promote fat burning.

PrimeShred also includes green coffee bean extract, complete with chlorogenic acid. Chlorogenic acid has been studied for its potential effects on weight loss, including reducing fat absorption and increasing fat metabolism, as we have seen.

Other ingredients found in PrimeShred include cayenne pepper, which has thermogenic properties that can increase body temperature and promote calorie burning, as well as DMAE (Dimethylaminoethanol), which may support focus and cognitive function.

PrimeShred is a perfect one, then, for those who often feel sluggish, lethargic, or muddle-headed on a calorie restricted diet – which plenty of people do.

It should do everything a good appetite suppressant and fat burner should, whilst also offering cognitive clarity and nootropic support. It’s very clever, pun intended.

PhenGold is an incredibly popular weight loss supplement that often forms a bit of a quality benchmark in the industry. It contains a potent blend of natural ingredients that work together to help suppress appetite, boost metabolism, increase energy levels, and promote fat burning.

PhenGold includes a rich helping of green tea extract. As we have seen, green tea gives you plenty of antioxidants and catechins, particularly Epigallocatechin gallate (EGCG).

PhenGold bottle and capsules

This EGCG, in turn, has been shown to enhance metabolism and increase fat oxidation, potentially aiding in weight loss, whilst also bringing down your appetite, as above. Green tea extract also has thermogenic properties that can help increase calorie burning and support overall metabolic function.

You also get a good dose of the amino acid L-tyrosine. As we have already learned, L-tyrosine plays a crucial role in the production of neurotransmitters like dopamine and adrenaline. It can help to improve focus, enhance cognitive function, and increase energy levels, particularly during calorie-restricted diets or intense workouts. Thus, PhenGold joins the ranks of appetite suppressing fat burners that also act as mild nootropics.

PhenGold also includes rhodiola rosea, one of my favourite nootropic ingredients. It’s an adaptogenic herb that helps the body cope with stress and fatigue.

Rhodiola rosea may help to increase energy levels, improve mental performance, and reduce feelings of fatigue and exhaustion, making it a valuable addition to a weight loss supplement – it should help you to stay calm whilst giving you the energy you need for your daily life and the odd extra hard workout.

Cayenne pepper comes next, with its healthy dose of capsaicin – which, as we have seen, can help increase body temperature and boost metabolism. It has thermogenic properties that may contribute to increased calorie burning and fat loss.

Other ingredients found in PhenGold include green coffee, which has been shown to support weight loss through its effects on fat metabolism, and Vitamin B3 (Niacin), which assists in energy production and supports overall metabolic function.

PhenGold’s blend of natural ingredients like green tea extract, L-tyrosine, rhodiola rosea, and cayenne pepper help suppress appetite, boost metabolism, increase energy levels, and promote fat burning, all whilst giving you a mild nootropic benefit. There is a lot to love here.

My Verdict

This is a hard one. Individual circumstances may push you to one option or another – for instance, I like a good nootropic kick in my supplements, meaning that Hunter Burn or PhenGold might be for me (though I get this separately, so it’s not too big a deal).

If you’re particularly active, going heavy on the stimulants may be your best option; if you are anxious and overeat, anything with L-tyrosine and/or rhodiola rosea is a good shout.

Capsiplex Trim bottle

However, if you are looking for a weight loss supplement that stands out from the rest, enabling impressive, useful appetite suppression, then Capsiplex Trim is well worth considering. With its blend of natural ingredients, including capsicum extract, caffeine, and black pepper extract, it offers several advantages that all come together incredibly nicely.

For instance, Capsiplex Trim’s inclusion of capsicum extract triggers thermogenesis, a process that increases body temperature and metabolism. This can propel your weight loss journey by supporting calorie burning.

Meanwhile, the caffeine content in Capsiplex Trim serves as a complete, full metabolism booster, giving you an extra edge in burning calories and potentially aiding weight loss efforts. It can improve exercise performance and increase energy levels, which can be particularly beneficial for those engaged in regular workouts (which is hopefully most people).

Additionally, chromium, capsicum extract, black pepper extract, and especially glucomannan have shown promise in reducing appetite and cravings. Incorporating Capsiplex Trim into your routine may help you take control of your portions and calorie intake.

Capsiplex Trim includes, in short, everything you need to support your weight loss journey. It’s terrific.

How Do Appetite Suppressants Work?

Fat burners and appetite suppressant supplements are amongst the most popular types of weight loss supplements available in the market. They are designed to support weight loss by boosting metabolic rate, increasing fat burning, and reducing hunger cravings.

The likes of Capsiplex Trim and PhenQ (see above) double up as both, simultaneously suppressing your appetite and aiding with satiation whilst also boosting thermogenesis, thus keeping your metabolism primed for optimal energy output and fat loss.

Appetite Suppressants

Appetite suppressants are designed to reduce hunger cravings, which can lead to lower calorie intake and weight loss. These supplements contain ingredients such as glucomannan (one of my personal favourites), chromium picolinate, and Hoodia gordonii, which work in different ways to reduce appetite.

Appetite suppressants work by targeting different mechanisms in our body to reduce feelings of hunger and control our appetite. One common approach is to affect the neurochemical transmitters in our brain, tricking it into thinking that we are not hungry. By acting on the central nervous system, these drugs can help reduce appetite and hunger, ultimately leading to a decrease in food intake.

Another way that appetite suppressants work is by targeting hormones that regulate our hunger and satiety levels. For example, some suppressants focus on increasing levels of serotonin, often referred to as the ‘feel-good’ hormone, which can trick the brain into feeling full and satisfied.

Additionally, certain appetite suppressants may target the adrenal gland, blocking the feeling of hunger by preventing the brain from receiving hunger signals.

Finally, some appetite suppressants may help by altering our body’s absorption of nutrients. They can work by reducing the absorption of certain fats from the food we consume, leading to a decrease in overall calorie intake.

Fat Burners

Thermogenic fat burners are believed to work by increasing your metabolism and promoting fat burning in the body. These supplements often contain ingredients that can elevate body temperature, such as caffeine, green tea extract, and capsaicin.

By raising your body temperature, thermogenic fat burners may help increase calorie expenditure and enhance the efficiency of fat burning, especially during physical activity.

Caffeine, a common ingredient in thermogenic fat burners, is known to stimulate the central nervous system and increase metabolic rate. Green tea extract is another popular ingredient. It contains compounds like catechins, which have been found to promote fat oxidation and thermogenesis.

Capsaicin, derived from chili peppers, can also increase metabolic rate and boost fat burning by activating certain receptors in the body.

It’s important to note that while thermogenic fat burners may have a modest effect on metabolism and fat burning, their impact on weight loss is often limited. They won’t burn fat for you – the difference can be 100 calories or so daily, which is minimal.

Rather, they are better used for metabolism optimisation, keeping your metabolism functioning fully as you run a restricted eating plan in conjunction with an active lifestyle.
