How We Ranked

Any appetite suppressant supplement can claim to block hunger. However, suppressing appetite is tricky. To rank the best appetite suppressant supplements, we used the following ranking factors:

Personal Testing & Reviews: Appetite is a subjective thing. Some people feel hungry all day long. Others only feel mild hunger. To rank appetite suppressant supplements, we personally tested the top-ranked formulas on our list and considered reviews. Our editorial team had slightly different experiences with most appetite suppressant supplements, although it was clear which ones performed better than others overall.

Clinically Proven Ingredients and Dosages: Science tells us that you can supress appetite and block hunger using proven ingredients. Some ingredients can effectively block hunger, while other ingredients do not. Fiber and certain herbal and plant extracts, for example, can trick your body into feeling fuller, helping you naturally eat less. The more clinically-proven ingredients and dosages were in an appetite suppressant supplement, the higher we ranked it.

Cost, Value, and Pricing: We believe you should be able to buy a good appetite suppressant regardless of whether you’re spending $20 or $240 on a one month supply. We featured appetite suppressants for all prices and budgets, although we made sure all supplements offered good value at their listed price.

Honest Advertised Benefits and Transparent Weight Loss Results: You should be wary of appetite suppressants that claim to offer fast weight loss with minimal effort. Some sleazy weight loss supplements claim you can lose 30lbs in just two weeks, for example, without dieting or exercising. Other appetite suppressants claim to eliminate all hunger for hours, which is unrealistic. We steered clear of appetite suppressant supplements with dishonest advertised benefits.

Manufacturer Transparency and Reputation: The weight loss supplement industry is filled with scams. Some companies have created appetite suppressants to make a quick dollar. Other companies have launched appetite suppressants as part of their award-winning lineup of reputable supplements. We preferred appetite suppressant manufacturers with a proven reputation for transparency and honesty.

Complementary Effects: Some appetite suppressants focus specifically on suppressing your appetite. Other appetite suppressants deliver complementary weight loss effects by acting as thermogenic fat burners, herbal weight loss aids, or carb blockers. We considered these complementary effects in our rankings, although we primarily focused on each supplement’s appetite supressing effects.

Label Transparency: Some weight loss supplement companies keep their formulas hidden, using proprietary labels to hide specific dosages. While we understand secrecy is important, we preferred weight loss supplements with maximum label transparency, including complete breakdowns of all ingredients and dosages within the formula.

Moneyback or Satisfaction Guarantee: Hunger is subject. Some people experience powerful appetite suppression benefits with some supplements with not others. Your hunger can be caused by different things – and blocked by different things. That’s why we appreciated appetite suppression supplements that were backed by a moneyback or satisfaction guarantee. When manufacturers stand behind their formulas with a promise, it suggests they’re confident the formula works as advertised to block hunger.

Who Should Take an Appetite Suppressant?

All types of people take appetite suppressants. Some people take appetite suppressants to break through a weight loss plateau. Others take appetite suppressants to boost their willpower, making it easier to lose weight.

Some of the people who could benefit from an appetite suppressant include:

  • Anyone trying to lose weight
  • Someone trying to break through a weight loss plateau or eliminate stubborn belly fat
  • Someone starting a new weight loss program for the first time
  • Anyone who needs an extra boost of willpower to eat less
  • Someone following a low-calorie diet who wants to avoid hunger pangs
  • Busy, on-the-go individuals who don’t have time to eat full meals during the day
  • Whether trying to lose weight for the first time or trying to smash through a weight loss plateau, a good appetite suppressant could help you lose weight.

Side Effects of Appetite Suppressant Supplements

Appetite suppressant supplements should not cause significant side effects when used by healthy adults in normal dosages.

Per FDA regulations, appetite suppressants must use ingredients and dosages that are generally recognized as safe (GRAS) by the United States Food and Drug Administration (FDA). Although supplements are not regulated by the FDA, supplement companies must use a specific list of supplement ingredients, and those ingredients have been determined to be generally safe to use by healthy adults in normal dosages.

However, some people experience the following side effects from appetite suppressant supplements:

  • Constipation
  • Indigestion
  • Diarrhea
  • Headaches
  • Fatigue
  • Nausea

Talk to your doctor before taking an appetite suppressant supplement if you have a medical condition or are taking any type of medication. Although unlikely, it’s possible an appetite suppressant supplement could interfere with your treatment program.

Note: If taking a prescription appetite suppressant drug, then you could experience more serious side effects. Talk to your doctor or pharmacist about appetite suppressant side effects before taking a prescription-strength appetite suppressant.

Appetite Suppressant Dosage

Check your appetite suppressant supplement for the recommended ingredients and dosages. Appetite suppressant supplements contain many ingredients at different concentrations and dosages.

With most appetite suppression supplements, you take one to two capsules 20 to 30 minutes before each meal. The appetite suppressant supplement should help you naturally eat less during the meal, making it easier to stick to your weight loss goals.

Science tells us that certain appetite suppressing ingredients work best at specific dosages.

Glucomannan, for example, seems to work best when taken at doses of 2,000mg to 4,000mg (2g to 4g) per day.

Garcinia cambogia, meanwhile, could suppress your appetite at doses of 1,000mg to 2,000mg per day, based on research.

Appetite Suppressant Benefits: What Does Science Say?

Some plants, herbs, vitamins, and minerals have been proven to suppress appetite. These ingredients have been verified to work in double-blind, placebo-controlled trials published in peer-reviewed journals. We’ll review some of that evidence below to determine the best appetite suppressants available today.

Many appetite suppressants contain conjugated linoleic acid (CLA), a type of trans fat found naturally in certain foods (particularly fatty animal products). Today, many people take CLA in supplement form to block appetite, reduce hunger, and stimulate fat breakdown. In fact, some appetite suppressants only contain CLA as an active ingredient – that’s how powerful CLA is believed to be.

In this study, for example, researchers found that conjugated linoleic acid increased fat burning and blocked the production of fat while suppressing appetite. Other studies have found similar effects, showing that CLA may increase feelings of fullness while decreasing appetite.

You may need a large dose of CLA for it to work properly: in this review covering 18 CLA studies, researchers found that a 3.2g dose of CLA reduced body fat. Similarly, this study showed that taking 3.6g of CLA per day for 13 weeks led to lower appetite and greater feelings of fullness than a placebo. If buying a CLA supplement for its appetite suppressing effects, try to choose one with at least 3g per serving.

Garcinia cambogia has been one of the most-prized appetite suppressing supplement ingredients in the last decade. Many people take garcinia cambogia daily to suppress appetite, block fat formation, and make it easier to lose weight. The peel of the garcinia cambogia fruit contains a compound called hydroxycitric acid (HCA) that is believed to have weight loss properties.

In this study, researchers found that garcinia cambogia reduced food intake, helping people naturally eat less and potentially lose weight. A separate study linked garcinia cambogia to appetite suppression, blocked fat formation, and lower body weight.

You may already take on of the best natural appetite suppressants daily: coffee is a proven appetite suppressant. Studies show that calorie can help you lose weight by boosting metabolism and increasing calorie burning. It could also help you eat less, making it easier to lose weight. In this study, researchers reviewed evidence on coffee and found that taking caffeine 30 minutes to 4 hours before a meal was linked with appetite suppressing benefits. In fact, this similar study found that people drinking coffee were less likely to eat after a meal and throughout the rest of the day, suggesting that coffee has all-day appetite suppression effects.

Some of the most proven appetite suppressing supplements are fiber supplements. Fiber works in a straightforward way: it soaks up water in your stomach and gut, then creates a gel-like paste in your digestive tract. Your body cannot digest fiber, so it sits in your gut and makes you feel fuller throughout the day. It can encourage digestive regularity and make you feel fuller for longer, helping you lose weight in two ways. Many people take fiber supplements daily for weight loss.

Glucomannan is one of the most popular types of fiber found in appetite suppressing supplements today. Glucomannan, like other types of fibber, absorbs water and becomes a gel, bulking up within your digestive tract to promote feelings of fullness and delay stomach emptying, allowing you to stay fuller for longer. In this long-term study on glucomannan, researchers told 83 overweight people to take 3g of a glucomannan supplement for one year. Researchers found a significant drop in body weight and fat after one year of taking the glucomannan supplement. In a similar study, a group of 176 participants to follow a low-calorie diet while taking a glucomannan supplement or a placebo. The glucomannan supplement group lost significantly more weight than the placebo group.

You may not have heard of fenugreek, but it’s another popular appetite suppression supplement ingredient, and many people take fenugreek daily to help them naturally eat less. Fenugreek, however, works because its seeds are 45% fiber. Fenugreek seeds contain a mix of soluble and insoluble fiber. This high fiber content has been linked to better blood sugar regulation, cholesterol, and appetite control, among other benefits.

By slowing the emptying of your stomach and delaying carb and fat absorption, fenugreek could suppress appetite significantly. In this study, researchers gave a group of obese women 8g or 4g of fenugreek fiber. The 8g group felt fuller and ate less than the 4g group, suggesting that fenugreek can help with appetite suppression.

Gymnema sylvestre is another herb that’s unknown outside of the supplement space but is a popular and proven appetite suppressant. Gymnema sylvestre is rich with compounds called gymnemic acids. These acids could prevent the absorption of sugar in the blood, which could stabilize your appetite. Most studies on Gymnema sylvestre have involved animals – not humans. This study showed that Gymnema sylvestre helped animals maintain their weight while being fed a high fat diet for 10 weeks, for example.

Green tea extract is one of the most popular weight loss aids available today, and many of the top-ranked appetite suppressants on our list contain green tea extract. Studies show that green tea extract could help suppress appetite because it contains catechins and caffeine. Caffeine, as mentioned above, has proven appetite suppressing and metabolism boosting benefits, making it a popular weight loss aid. Meanwhile, catechins in green tea, including EGCG, also seem to suppress appetite and boost calorie expenditure.

Ultimately, appetite suppressants can have powerful effects on weight loss. A good appetite suppressant encourages you to eat fewer calories, making it easier to stick to your weight loss goals. Science tells us that certain ingredients, including coffee, caffeine, green tea powder, and fiber, are all linked to powerful appetite suppressing results.
