Top 5 best appetite suppressants of 2021
LeanBean: Best appetite suppressant for women
LeanBean is the best appetite suppressant on the market for women. Developed by renowned UK supplement manufacturer Ultimate Life Ltd, LeanBean is a fat burner supplement tailored to female physiology. Women who take it will enjoy a suppressed appetite, increased energy levels during exercise, and accelerated metabolism.
Many appetite suppressants that have been designed for men contain large amounts of caffeine compounds that can cause adverse side effects in women. LeanBean, on the other hand, uses stimulant-free ingredients that facilitate the weight loss process, including the thermogenic spice turmeric, the metabolism-boosting nutrient choline, and 10 others, making it the best appetite suppressant out there for women.
In particular, these weight loss pills contain a much higher glucomannan dose than that of competing products. Each serving provides 3g of glucomannan, the daily amount clinically proven by the European Union to curb feelings of hunger.
Plus, the supplement’s hearty dose of B vitamins will help you fight tiredness during your workouts as well as improve your overall health.
Take a look at the complete LeanBean formula:
- Chromium Picolinate
- Vitamin B6
- Vitamin B12
- Green coffee
- Garcinia cambogia
- Acai berry
For ideal results, you should take two LeanBean capsules three times throughout the day.
Women who want to lose weight by eating less while staying active should consider LeanBean. It answers your body’s specific needs and gives you that extra boost to shed stubborn pounds. If you’re still having trouble attaining your perfect bikini body, though, you can get your money back within 90 days.

PhenQ: Top appetite suppressant and fat burner combo
PhenQ is the top appetite suppressant and fat burner combo. Last year, trusted supplement manufacturer Wolfson Berg Limited debuted its new appetite suppressant, PhenQ. While both women and men can use PhenQ to lose weight, women over 40 will find great success with the product because it combats symptoms associated with menopause, such as fatigue and weight gain around your midsection.
When you take PhenQ, its natural ingredients help your body regulate your appetite, burn persistent fat cells, and increase your metabolism to give you more energy. It also provides key nutrients needed to stay healthy.
Capsimax powder is the secret behind PhenQ. This science-backed combination of several compounds contributes to weight loss by raising your metabolic rate and acting as an appetite suppressant. Your body naturally burns extra calories, resulting in a smaller waistline.
PhenQ’s formula consists of:
- Capsimax powder: capsicum, piperine (black pepper), caffeine, and niacin (vitamin B3)
- Chromium picolinate
Suppressing your appetite with PhenQ is quite easy. Just taking one pill per day is enough to see results. Because it contains caffeine, be careful not to take it in the evening, or you might have trouble sleeping at night.
If you’re a woman over 40 who has struggled to lose weight using diet and exercise alone, then PhenQ is the appetite suppressant for you. Even if you aren’t an avid gym-goer, PhenQ helps you lose extra pounds with no added effort. Best of all, you get free shipping as well as a 60-day money-back guarantee.

Instant Knockout: Strongest appetite suppressant for men
Instant Knockout is the best appetite suppressant supplement for men. When Instant Knockout was first established, UK supplement manufacturer Roar Ambition Ltd had designed it with professional MMA fighters and boxers in mind—hence the name. However, you don’t need to be a fighter to take it. Any man can use this appetite suppressant supplement to lose weight.
Instant Knockout includes 10 natural ingredients that reduce food cravings, boost energy, and induce weight loss, even when you’re sitting or lying down. Men love it because it keeps them from snacking all day but also gives them the energy to hit the gym.
They also like that the appetite suppressant comes with a 90-day money-back guarantee. Ingredients include:
- Green tea extract
- Caffeine anhydrous
- GTF chromium
- Cayenne powder
- Green coffee
- Vitamin B12
- Vitamin B6
Instant Knockout recommends taking four capsules taken throughout the day — one before breakfast, another at lunchtime, a third in mid-afternoon, and a fourth in the evening before dinner.
If you tend to eat your last meal late, make sure to take the final pill a bit earlier, because Instant Knockout contains caffeine that might keep you awake at night.
While people of any gender who want to eat less can use Instant Knockout, men may see particularly phenomenal weight loss results. Instant Knockout’s unique combination of ingredients is best for a man who needs to eat less but is tired of feeling drained at the gym.

Powher Cut: Natural hunger control pill
Powher Cut is the most effective hunger suppressant for increased energy. Ultimate Life also produces the Powher line of products, which includes a pre-workout product, a sleep supplement, a nootropic, and the one we’re reviewing today: the appetite-suppressing fat burner. It’s worth noting that you can stack any and all of these together, depending on your health and lifestyle goals.
As its name suggests, the Powher appetite suppressant was specifically formulated to help women lose weight. Compared to LeanBean, Powher contains more stimulants, which makes it one of the best appetite suppressant supplements for boosting energy and decreasing fatigue while dieting.
Since women are more prone to iron deficiencies than men, Powher delivers 100 percent of your daily iron to reduce your risk of anemia. Conditions like anemia cause tiredness and fatigue, which is counterproductive when you’re dieting.

Trimtone: Best value
Trimtone was developed by Swiss Research Labs Unlimited as an appetite suppressant to help busy women resist food cravings and burn fat for a reasonable price.
Along with other natural ingredients that support several processes in the body, Trimtone contains a unique thermogenic fat burner, a spice called grains of paradise. The grains activate brown adipose tissue, lowering blood sugar levels and producing heat that speeds up your metabolism.

How do appetite suppressant pills work to reduce hunger?
Appetite suppressants have a few different methods of making you less hungry. Some slow digestion, some take up space in your stomach, and others even boost the production of hunger-reducing hormones.
Let’s examine the three main methods these supplements use to help you suppress your appetite.
Keeping you feeling full
Many appetite-suppressing products are rich in fibers like glucomannan, which take longer to move through your digestive system. Since an empty stomach usually triggers a hunger response, staying full will decrease your appetite.
Hormones like leptin and peptide YY also play an essential role in the hunger response, so increasing their levels in the body will help you eat less.
Increasing available energy
Since our bodies get energy from the nutrients in food, maintaining optimal energy levels can decrease the need to eat. Thermogenic hunger suppressants often use vital nutrients, like B vitamins, to create energy by burning fat. As energy increases, more fat is burned. As more fat is burned, more weight is lost.
Mitigating emotional eating
Eating often serves as an unhealthy coping mechanism. Who among us hasn’t dug into a tub of ice cream or drank a little too much after a painful breakup?
Fortunately, boosting your mood can prevent the urge to use food as a crutch. Many appetite suppressants contain caffeine and B vitamins, which have been documented to raise your energy and serotonin levels.
Factors to consider when choosing the top appetite suppressants
Before you buy an appetite suppressant, you should always read the nutrition label carefully. Sometimes manufacturers use filler ingredients like magnesium stearate or silicon dioxide to drive production costs down, but those ingredients provide no value. Look for research-backed ingredients that genuinely help to reduce hunger.
You also want to make sure that the supplement contains a high enough amount of each ingredient to be effective. For example, the EU studies mentioned earlier have proven that glucomannan works best when you ingest at least three grams of it, but some supplements don’t include nearly that much.
A brand’s advertising efforts will make you believe that their product is the best appetite suppressant supplement on the market, but is that really the case? A surefire way to tell is to see what others who have purchased the diet pill have to say about it.
Reading the objective opinions of real people with real weight loss concerns will give you a better understanding of what you can expect from a weight loss supplement. You should peruse a mix of positive and negative reviews to learn what most people think the pros and cons are.
That said, keep in mind that since everyone’s body is different, an appetite suppressant that worked for one person may not give you the same results.
If you choose one of the natural appetite suppressants on our list and take it as directed, you don’t have to worry about harmful side effects. However, you should still review all manufacturer claims to make sure that you’re purchasing a supplement that’s healthiest for you.
For even more peace of mind, check out published opinions on each ingredient’s potential side effects.
You should also keep an eye out for banned ingredients. For example, it’s been illegal to sell supplements containing ephedra since 2004. Ephedra is a naturally-occurring plant extract that can be lethal to humans, and you want to avoid it at all costs.
Stimulant or non-stimulant?
Many appetite suppressant supplements use stimulants like caffeine to boost your energy levels, which is crucial since eating a more restrictive diet than you’re currently used to can cause fatigue.
However, you need to think about your tolerance of stimulants before making a purchase. If you struggle with insomnia or anxiety, caffeine can aggravate these conditions. Likewise, if you dislike the jittery feeling that often comes with stimulant ingredients, you might want to consider a non-stimulant option. And if you take a stimulant medication, you should talk to your doctor before adding any supplements that contain stimulant ingredients.
Plus, if you already drink coffee or energy drinks frequently throughout the day and don’t want to change that habit, you probably don’t need the extra dose of caffeine.
Appetite-suppressant prices vary greatly, ranging from $10 to more than $70 per month. And while price can indicate quality, you shouldn’t base your decision solely on this factor.
To determine whether or not an appetite suppression supplement is worth the money, consider its portion of effective ingredients, the number of capsules in a bottle, and the brand’s reputation.
In the end, it’s up to you to decide how much you’re willing to spend. Luckily, you can usually take advantage of exclusive discounts on the brand’s official website, and you can save even more by buying in bulk.
Clean label versus proprietary formula
If you ever see the word “proprietary” on an appetite suppressant label, remove that bottle from your cart immediately. Since proprietary formulas only list the ingredients in weight order instead of disclosing the full amounts, manufacturers can use them to stretch the truth regarding the exact contents of their product.
A proprietary blend’s laundry list of ingredients may appear impressive, but some ingredients —especially the most expensive ones—might be provided in amounts so marginal that they won’t have any impact.
To ensure that you’re getting sufficient quantities of each ingredient, stick to appetite suppressants with straightforward, clean labels like the ones we’ve reviewed.
Natural ingredients that suppress your appetite
Conjugated linoleic acid
Naturally found in some animal products, conjugated linoleic acid (CLA) is the most common omega-6 fatty acid. Research shows that CLA can affect appetite-regulating genes and hormones, burn fat, and increase lean body mass.
In one study, 54 people given 3.6 grams of CLA each day for 13 weeks experienced lower appetite and greater levels of fullness than those taking a placebo.
Bitter orange (synephrine)
Native to Southeast Asia, bitter orange contains synephrine, a compound that may aid in appetite suppression. A review of 23 studies found that a daily dose between 20 and 35 mg of synephrine increased the rate at which the body burns calories while at rest, facilitating weight loss.
Garcinia cambogia is an Indonesian fruit that has high amounts of hydroxycitric acid in its skin. This acid is a substance that can help you lose weight by leaving you more satisfied after meals and preventing the body from storing fat.
The principal ingredient in appetite suppressant products, glucomannan is a dietary fiber that comes from the root of the East Asian konjac plant. Upon exposure to water, glucomannan expands, taking up space in your digestive system to help you feel full.
This South Asian herb has long been lauded for its appetite-suppressing and endurance-enhancing abilities, possibly achieved through increasing the circulation of serotonin in the brain.
In a study of people with Prader-Willi syndrome—a rare health condition that leads to overeating—participants who took 1,000 mg of caralluma fimbriata every day for four weeks experienced significant reductions in appetite and food intake levels.
Green coffee bean extract
Before they’re roasted in preparation for consumption, coffee beans are green and contain only small amounts of caffeine. However, unroasted coffee beans are rich in an antioxidant called chlorogenic acid that inhibits sugar cravings and blasts belly fat. Therefore, green coffee bean extract can help you lose weight.
Green tea extract
Although green tea has not yet been proven to directly suppress appetite, the extract is often included in diet pills because of its success as a fat burner. Green tea may boost the metabolism by increasing the production of the fat-burning hormone norepinephrine. It also provides your body with lots of catechins, antioxidants that prevent fat absorption.
Additionally, green tea extract reduces your levels of triglycerides, one of the main forms of body fat. And like many other teas, it contains caffeine, which boosts your energy levels.
Some scientists believe that forskolin extract may help with weight loss by suppressing your appetite, enhancing your metabolism, and speeding up the body’s fat-burning process. More research is still needed to confirm these theories.
Hailing from South America, the yerba mate plant has developed a reputation for boosting energy levels and reducing appetite. One study in mice revealed that long-term consumption of yerba mate led to increased production of the compound glucagon-like peptide 1 (GLP-1) and the hormone leptin, both of which contribute to appetite control.
This essential trace mineral has demonstrated an ability to support the metabolism of macronutrients—carbohydrates, proteins, and lipids (which include fats). By effectively controlling blood glucose levels, the mineral makes it easier to fight your sugar and carb cravings.
What are the health benefits of taking appetite suppressants?
Feeling fuller between meals
Decreasing your food intake can make you feel hungrier than you should be, especially if your body has become accustomed to overeating.
But there’s good news: Eating less doesn’t have to feel like you’re on a starvation diet. On the contrary, appetite suppression products can keep feelings of hunger at bay so you can abstain from snacking in between meals.
Increased energy levels
You’ve probably tried a diet that left you feeling exhausted every day. That tends to happen when you stop giving your body as much fuel as you once did.
However, feeling that tired is counterproductive when you are trying to shed weight. You wind up with less energy and cannot maintain a rigorous fitness regimen. Your body then craves more food to replenish the lost nutrients.
Fortunately, appetite suppressant supplements provide you with a much-needed boost of energy since they often contain stimulants like caffeine that will keep you awake. Plus, many of their ingredients will accelerate your metabolism, helping your body convert nutrients into even more energy.
Curbed hunger cravings
How often do you find yourself reaching for potato chips or cookies because they’re just too delicious to resist? Unfortunately, goodies like these contribute to the formation of fat cells, so you should avoid them if you want to reach your weight loss goals.
When you suppress your appetite with a supplement, you’ll eradicate the pesky food cravings that arise when you start to feel hunger. As a result, you’ll have less trouble swapping sugary and fatty snacks for health-conscious alternatives.
An appetite suppressant can help you lose weight, which is likely the main result you’re looking for.
The logic is simple — if you feel less hungry, you’ll eat less food, decreasing your calorie intake. Plus, weight loss supplements speed up your metabolism, helping your body burn more calories than you consume each day.
With these two factors in play, the weight will start to come off before you know it.
Prescription appetite suppressants versus natural supplements
For patients with particular health conditions, a doctor may prescribe phentermine, topiramate, and other prescription medications to control a patient’s appetite and help them lose weight. Because these drugs are potent, they usually carry higher risks of side effects like gastrointestinal issues. Due to this risk, you can only get them from your healthcare provider.
If you haven’t been diagnosed with a particular medical condition, though, you can get healthier weight loss pills over the counter in the form of natural appetite suppressant supplements. Although a bit weaker and less risky than their prescription counterparts, these natural products still have great potential to work for you.
Either way, you should consult with your doctor before making your decision, since your health care provider knows your medical history.
Are appetite suppressants safe to take?
As long as you opt for natural products like the appetite suppressants we’ve reviewed and take them as directed, you shouldn’t experience any worrying side effects. While artificial ingredients can negatively impact your body, the natural components of our chosen supplements usually only improve your overall health.
In general, the side effects you should keep an eye out for are related to caffeine sensitivity. The stimulants in some appetite suppressants can trigger some of those same side effects, such as headache, jitters, insomnia, anxiety, and rapid heart rate.
You should also know that some appetite suppressants may interact with other drugs. For instance, the chromium picolinate in PhenQ and LeanBean may interfere with diabetes medications.
In addition to diabetes, other autoimmune disorders, cancers, and some predisposed health conditions might make appetite suppressants unsafe for you. And of course, women who are pregnant or breastfeeding should avoid appetite-suppressing products until the baby is no longer nursing.
Otherwise, healthy adults generally have no issues taking an appetite suppressant. However, it’s always a good idea to check with your doctor before taking a weight loss supplement.
Do appetite suppressants really work for weight loss?
Science has shown that, yes, appetite suppressants work.
However, you must make sure that the supplement contains clinically proven ingredients in adequate doses and that you take it consistently, following the instructions on the bottle.
How quickly you’ll see results from appetite suppressants will vary depending on your body physiology. While some people start to lose weight in a few days, it may take others weeks or months for significant weight loss to occur. Continue to take your appetite suppressant for at least two months before you decide that it hasn’t helped you shed any body fat.
For the best results, though, you will need to put in some work. No fat burner or appetite suppressant will magically whittle your waist.
Supplements work in tandem with your efforts on the diet and exercise fronts. Therefore, an appetite suppressant needs to be one part of a total weight loss program complete with significant lifestyle changes.
Lifestyle changes that make appetite suppressants more effective
To keep your total daily energy expenditure (TDEE) higher than your daily caloric intake, you need to expend more energy. According to the Mayo Clinic, you should perform at least 2.5 to 5 hours of moderate physical activity or 75 to 150 minutes of vigorous aerobic activity per week if you want to lose weight.
If you currently lead a sedentary lifestyle, that much exercise can sound impossible. Start small and gradually increase the length and intensity of your workouts.
It helps if you choose a form of physical activity that you genuinely enjoy, whether that’s running, dancing, biking, or lifting weights. Don’t be afraid to try multiple activities and see what works best for you.
Eating more fiber
Unlike other foods, insoluble fiber passes through the digestive system relatively intact because our enzymes can’t break it down. Even soluble fibers will keep you feeling fuller for longer; just look at glucomannan, which expands in your stomach.
A few foods that contain high levels of fiber include:
- Whole grains
Consuming more protein
Research has shown that eating foods rich in protein may also help suppress your hunger naturally. Protein causes your brain to release a hunger-regulating hormone called peptide YY.
A study done with mice supports this theory. The mice who ate more protein produced more peptide YY and, as a result, put on less weight than the mice that ate smaller amounts of protein.
Some foods that contain high levels of protein include:
- Chicken and turkey breast
- Greek yogurt
Drinking more water
One easy way to eat less is to drink more water. Clinical studies revealed that 37 percent of people frequently mistake thirst for hunger, so they eat more when they actually need fluids instead.
Furthermore, your stomach will send a signal to your brain telling it to stop eating whenever it gets full, even if it’s only full of water. Therefore, drinking more water will make you feel full since there’s less room for food.
When you take your appetite suppressant supplement before meals, you should wash it down with a large glass of water so that you won’t feel as hungry when you sit down to eat. This might also help reduce side effects from the supplement.
As if that wasn’t enough of a reason to increase your daily water intake, drinking more of the beverage brings increased energy and faster metabolism.
Who should use appetite suppressants?
Since the main goal of taking an appetite suppressant is weight loss, anyone who is overweight or obese will benefit from taking a supplement.
If you’re already at a healthy weight or are underweight, however, taking a hunger suppressant could be harmful to you.
Men and women alike can benefit from appetite suppressants, although you should make sure that the appetite suppressant you want to purchase is appropriate for your gender. Some supplements contain ingredients that increase levels of male hormones in the body, while others work better for women.
How much do appetite suppressants cost?
The cost of an appetite suppressant depends on many factors, including the number and amount of science-backed ingredients, the number of capsules per bottle, and public opinion of the brand.
Usually, anywhere in the $50 per month range generally strikes a good balance between cost and quality.
Final thoughts — are appetite suppressants right for you?
If you want to consume fewer calories every day, appetite suppressants work. These pills will help you eat smaller portions and snack less frequently. This change will result in weight loss when accompanied by healthy diet and exercise habits.
If you take the weight loss pills as directed, they may be the last remedy you’ll ever have to try.
As you would with any substance, you should always consult your doctor before adding appetite-suppressing products to your regimen, even though these supplements can help you reach a healthy weight with minimal side effects. Armed with complete knowledge of your medical history, your health care provider will be best equipped to help you figure out the best appetite suppressant for your body.
Another benefit of seeking professional medical advice is that your doctor will have a wealth of tips for creating a diet plan and workout routine to help you get the most out of your appetite suppressant supplement.
