Best Fat Burner Pills For Men And Women

The fat burner pills industry has grown exponentially in the last few decades, creating and manufacturing supplements that are supposed to be able to give our bodies the jumpstart we need, helping us reach a healthier weight.

But this growth does not only mean that there are more products that actually work on the market, it also means that there are more products that don’t work floating around out there.

We’re not interested in spending our money on products that aren’t going to work—especially in the middle of a recession—and we don’t think you should have to either.

That’s why we did some research to find out which diet pills contain the right ingredients to help you lose as much weight as possible without getting overly frustrated or spending too much money.

Best Fat Burner Pills For Men And Women

We put together a list of some popular over the counter fat burners that have shown promising results, helping you decide which ones are going to be the right fit for you.

Fat burners make up the large majority of diet pills on the market today. Also known as thermogenic diet pills, fat burners are usually stimulant based diet pills that effect the central nervous system, diverting the receptors in the brain allowing your body to utilize its natural fat burning abilities.

Due to their fast acting results and (for the most part) powerful formulas, fat burners were made popular by body builders looking to shape and sculpt their bodies by eliminating the last bit of fat in their system before competitions and performances.

This generation of fat burners also allows you to increase metabolism and increase lean muscle within the body.

  • Vitamin B Complex
  • Bioperine – 5mg

The ingredients have different ways of aiding fat loss. A number of the ingredients are proven thermogenics such as green tea, caffeine and cayenne pepper extract that burn fat by increasing the body’s metabolic rate.

Green Tea Extract

The product contains a high dose of green tea extract at 500 mg per 3 capsules. Green tea is an effective natural thermogenic used by many fat burner products out there.

It is a safe and natural fat burner with high levels of antioxidants. The polyphenols in green tea help increase the body’s metabolism and therefore increasing the rate at which the body burns fat.

Caffeine

Caffeine works by increasing the catecholamine level in the blood. Catecholamines help to mobilize fat stores which in turn results in increased fat burning.

Caffeine can also make you more alert and energetic which is great before workouts so you can perform at your best.

A number of research studies have focused on green tea and caffeine as natural stimulants and a number of them found supporting evidence of their fat burning properties.

Rhodiola Rosea

Considered by Russian Scientists to be an adaptogen (an herb to increase stress and fatigue resistance), Rhodiola Rosea can help support and maintain healthy heart functions.

By including Rhodiola in your diet, you’ll experience an increased ability to normalize heart rate after an intense workout.

Additionally, Rhodiola can enhance mood and memory while reducing headaches and fatigue.

Green Coffee Bean Extract

Coffee beans before they are roasted offer a number of benefits but the high concentration of chlorogenic acid is the key to losing weight. In studies users have lost an average of 15 to 17 lbs.

L-Tyrosine

The next main ingredient L-tyrosine’s primary function is to build proteins. It also plays a vital role in maintaining a healthy mood, combating stress and fatigue.

Some preworkout supplements use it to help you give a boost of energy. Some research suggests, that in higher doses it facilitates weight loss by increasing the body’s metabolism.

L-Theanine

It is an amino acid found in tea. Countless studies have proven the effectiveness of green tea specifically as a weight loss ingredient. However, studies have also shown that when L-Theanine is combined with Caffeine, it resulted in improved cognitive functions. So L-Theanine is not only a natural and safe stimulant but also a natural brain booster when combined with caffeine.

Cayenne Pepper

Cayenne Peppers, members of the plant genus “capsicum” (to bite”), contain compounds called capsaicinoids. This unique features help Cayenne Pepper boost your metabolism and lose fat.

There are some additional supporting ingredients as well.

Vitamin B6

Vitamin B6 is an essential coenzyme in the body which has been used to metabolize amino acids, glucose, and lipids for a healthy body and healthy muscle mass.

It is essential for the synthesis of proteins that build, strengthen, and feed the muscles, metabolizing stored carbs and regulating healthy blood sugar levels, increasing body energy even with reduced calorie intake. Vitamin B6 converts fat into energy.

Vitamin B12

Vitamin B12 is an essential vitamin that has many different uses. It can be used throughout the body to produce healthy DNA strands in every part of the body while improving healthy red blood cell regeneration.

It is found in every area of the body, and vitamin B12 can help during intense workouts while providing a steady stream of oxygen which turns ATP molecules into fuel. Vitamin B12 supplies the oxygen that your muscles need to build healthy red blood cells.

Dimethylaminoethanol – DMAE

It contains powerful anti-inflammatory properties. DMAE helps the production of neurotransmitters, which may help cognitive function, increase muscle tone and firm skin. It also enhances the effects of other antioxidants in PrimeShred.

BioPerine

This is a patented black pepper known to inhibit enzymes that metabolize important nutrients.

BioPerine enhances nutrient and food movements through the digestive tract and activates amino-acids in the intestinal lining, therefore improving the absorption of all other ingredients.

Potential PrimeShred Side Effects

All medicine and supplements have a chance of side effects, some more extreme than others with a varying degree in between.

There’s a small chance PrimeShred can negatively affect some users, that’s because its formula uses a variety of stimulants.

Stimulants are effective, but a small group of people cannot take them. Some PrimeShred users who are sensitive to caffeine reported feeling negative side effects like insomnia, headaches, dizziness, and trouble focusing.

If you experience these rare symptoms, you should discontinue use or take half the recommended dosage until your body develops a stronger tolerance, and then resume normal dosage.

Our Verdict

This is one of top recommended fat burner and we gave it a near perfect rating.

The ingredients and amounts are clearly visible on the bottle. So you can be sure that there are no hidden side effects.

The main thermogenic, green tea is a proven and safe ingredient and there is a high dose of it in the product. Caffeine is also a proven natural thermogenic and the dosage is substantial.

Both of these ingredients will increase your metabolism and help you get results faster.

Where can I buy Trimtone?

Trimtone is only available from the company’s website. It is not available from Amazon or Ebay or other supplement retailers.

Trimtone Ingredients

Trimtone contains 5 natural ingredients. Everything clearly stated on the label so you know exactly what you are taking.

  • Green Tea Extract – 100mg
  • Green Coffee – 100mg
  • Caffeine Anhydrous – 120mg
  • Grains Of Paradise – 40mg
  • Glucomannan – 100mg

The ingredients in this formula are a combination of thermogenics and appetite suppressants.

Green Tea Extract

Trimtone contains a high dose of Green Tea Extract at 100 mg per capsule. Green tea extract is a staple ingredient of quite a few fat burners out there due to the number of studies that have shown the effectiveness of this natural thermogenic .

Green tea extract works by increasing the body’s metabolism which in turn results in better fat burning. Besides, you get plenty of antioxidants.

Green Coffee

Green coffee beans are unroasted coffee beans. They contain a chemical called chlorogenic acid. It has been linked to weight loss amongst other health benefits.

When coffee is roasted, the amount of chlorogenic acid in the beans is reduced. Therefore, drinking loads of cups of coffee won’t give you the same effect as green coffee would.

Studies carried out on humans showed promising results of chlorogenic acid’s ability to reduce absorption of carbohydrates, resulting in weight loss.

Caffeine Anhydrous

Caffeine is a proven and natural thermogenic ingredient that increases the body’s metabolic rate, helping it to burn more fat.

Grains Of Paradise

Grains of paradise is a proven fat burning ingredients because of its potential to reduce the accumulation of white adipose tissue. What’s more, it stimulates the brown adipose tissue (BAT) and increase thermogenesis and natural use of energy (calories).

Stimulation of BAT is important, because it burns calories and produces heat.

Glucomannan

As a potent fat burner, Trimtone also contains natural appetite suppressantGlucomannan. 1 capsule contains 100 mg of this dietary fiber.

When glucomannan is mixed with water it swells up in your stomach, therefore making you feel fuller and reducing the likelihood of cravings throughout the day.

Research has shown this natural dietary fiber to be an effective and safe appetite suppressant.

Potential Side Effects Of Trimtone

On the Trimtone website under the FAQ section, the seller states that this product is “completely safe”. Although as the product states all ingredients and their amounts on the label, there is very little risk of unwanted side effects.

However, if you are allergic, sensitive or intolerant to caffeine, there is still a chance that you could experience some side effects.

Also, if you are taking this product in the afternoon, it might cause problems with sleep due to the caffeine content.

Our Verdict

This natural fat burner is transparent about the ingredients and amounts in its formula and it is easy to use.

It contains some proven natural thermogenic ingredients like green tea, green coffee, and caffeine. As well as the right ingredients, the amount of green tea extract in each serving is sufficiently high in order to aid fat loss.

This natural fat burner for women also contains proven and natural appetite suppressing ingredients like glucomannan and the dose seems to be high enough to help keep control of cravings.

Best Fat Burners For Women

Being a gluten and dairy free product is also a bonus for those intolerant or sensitive to these ingredients.

This is a great product and I would definitely recommend choosing a fat burner for women like Trimtone if you are looking for a natural, safe and effective fat burner for women.

  • L-Tyrosine – 300mg
  • L-Theanine – 250mg
  • DMAE – 150mg
  • Vitamin B Complex
  • Bioperine – 5mg

Thermogenics

Caffeine increases catecholamine level in the blood. These chemicals are responsible for mobilizing the fat stores enabling the body to burn more fat. Caffeine also gives the body an energy boost you need before workouts so you can go harder in the gym.

Green tea is a safe and natural fat burner rich in antioxidants. It increases energy levels and helps you to achieve your best during your workouts. It contains polyphenols that increase the body’s metabolism, increasing the rate at which the body turns food into energy.

Both green tea and caffeine are extensively researched natural stimulants with a number of studies backing their effectiveness in reducing body fat.

The formula also contains green coffee bean extract (4:1) of 100 mg per serving . Green coffee beans contain a chemical called chlorogenic acid. A number of human studies have shown this component’s ability to reduce the absorption of carbohydrates from food, therefore aiding weight loss. The daily amount is sufficiently high to achieve results.

Rhodiola Rosea Root

Rhodiola has been through extensive research, and it has been shown to increase cyclic AMP, inhibiting platelet activation. It stimulates the thyroid, releasing more hormones and fueling metabolism, increasing blood flow to the muscles and energy to help you to lose more weight. Clinical studies show that Rhodiola can reduce body fat and increase lean muscle mass at the same time for better body composition.

Mood enhancers

One of the main ingredients in the formula is L-tyrosine. This ingredient helps in maintaining a healthy mood, combating stress and fatigue.

Pre-workout supplements use L-tyrosine as one of their ingredients to give you a boost of energy. However, in higher doses it also facilitates weight loss through thermogenesis.

L-Theanine is an amino acid that can be found in tea leaves and it has been previously linked to an increased mental function in human studies.

There have been a few animal studies linking L-theanine to weight loss. Research conducted on mice back in 2004 found that the caffeine and theanine found in green tea were responsible for its suppressive effect on body weight increase and fat accumulation.

A more recent study conducted on rats found that L-theanine could be responsible for inhibiting the absorption of glucose and secretion of insulin.

This finding indicates that L-theanine could be key to achieve weight loss.

Supporting ingredients

Additional to the core ingredients, PhenGold also contains a number of supporting ingredients like B vitamins (improve muscle action), Dimethylethanolamine (DMAE) and Bioperine (boosts other ingredients absorption).

Potential PhenGold Side Effects

The most common side effects of this product can be caused by the caffeine content. If you are allergic or sensitive to caffeine, this product may not be for you.

L-tyrosine is also associated with side effects such as restlessness, anxiety, and even insomnia, but only in huge doses.

Our Verdict

Following the above review, we’ve rated this product a higher than average.

The product price is competitive and the ingredients and their doses are clear on the label.

PhenGold contains some proven, natural ingredients like green tea, caffeine and cayenne pepper. All of which are thermogenics. The green tea and cayenne content is sufficiently high in order to achieve fat loss results.

L-tyrosine is also natural thermogenics. However, there is not as much research evidence showing its effectiveness as there is for green tea or caffeine.

Best Fat Burners In The Market

The product acts in 3 ways, by increasing metabolism, suppressing appetite and improving mood.

We’ve also found genuine looking customer reviews on Youtube and found engagement around this product on social media sites like Instagram which is a good sign of an effective product.

So all in all, this is a great product. However, it could be improved by adding some well-researched, natural appetite suppressants like glucomannan.

PhenQ Ingredients

Here are the ingredients in PhenQ and their mode of operation in the body to help you lose body fat and hence reduce weight.

  • α-Lacys Reset® (25mg)
  • Capsimax powder (15.5mg)
  • Chromium Picolinate (80mcg)
  • Caffeine (150mg)
  • L-Carnitine Fumarate (142.5mg)
  • Calcium Carbonate (625mg)
  • Nopal (20mg)

α-Lacys Reset®

This is a formula that has been patented and unique to PhenQ. It was developed through a lot of research. This ingredient is safe and helps to raise the metabolism of the body by initiating the process of thermogenesis. With your metabolism in overdrive you can be sure to burn more fat throughout the day whether you are working out or just resting.

Capsimax powder

This is a powder made by mixing capsicum, piperine, caffeine and niacin. Capsicum and piperine are excellent products at raising the metabolism of the body. Piperine further, is also believed to be able to stop formation of new fat cells meaning you burn more and store less.

Chromium Picolinate

This ingredient helps to control sugars in the body. It reduces the cravings for sugar and also regulates the sugar levels in the blood. When you do not crave sugar and carbs you will be able to lose weight faster.

Caffeine

It is a well known stimulant. It helps you body to become more alert, increases focus and reduces fatigue. It is also known to raise the metabolism of the body though thermogenesis. With increased performance you will be able to get more from your workout if you are working out. Caffeine also is known to keep you feeling full so you eat less.

L-Carnitine Fumarate

It is a naturally occurring amino acid mostly present in green vegetables, red meat, and nuts. Here it is present at 150 mg per serving. Its function is to assist the body in using stored fat to energy, thereby leaving you more energized and less obese. It also helps in combating tiredness that is a natural outcome of taking limited diet.

Calcium Carbonate

After the secret ingredient, the principle ingredient present is calcium carbonate at a whopping 625mg per serving.

While the benefit and importance of calcium for bones and teeth is no secret, not many are aware of the role of calcium in weight loss. Recent studies indicate that calcium can actually discourage the body to store fat by sending signals of a well-nourished body to the brain.

Consequently, instead of craving foods for energy requirements, the body actually burns its own stored fat to meet the energy requirements.

Nopal

Present as 20 mg per serving, it is a cactus with high fiber content along with appetite-suppressing properties.

Loaded with amino acids, it helps flush out excess fluids from the body, thereby assisting in weight loss. Its fiber content reduces the hunger pangs while it’s another component, pectin aids in decreasing the absorption of sugars to maintain blood sugar levels.

As you can see here all the ingredients are natural ingredients and they have been studied extensively to investigate their efficacy.

Potential PhenQ side effects

Due to authentic natural ingredients, PhenQ will not cause any serious side-effects. However, minor side effects can manifest, predominantly due to the presence of calcium carbonate.

These can be constipation, gas, headache and mental confusion, nausea/vomiting, headache, thirst, anxiety and jittery feeling, itchiness etc.

However, these generally fade over time. If they do not, it’s best to consult a doctor and discontinue if required.

Our Verdict

Like any other dietary supplements, PhenQ is no magic supplements and show its results gradually and over time. After continued use, it soon helps the person to lose weight permanently.

Going by the standards, the fat burner PhenQ can help anyone lose 2-5 pounds per week without requiring any extra hard work at the gym or any possible side effects. The pill should be taken regularly for about three months for satisfying results.

  • Bitter Orange – Synephrine (150mg)
  • Garcinia Cambogia (150mg)

Synephrine

This in particular is a compound of bitter orange. A compound which has similar effects to that of ephedra, an ingredient previously banded by the FDA due to the related health risks.

Synephrine is considered to be a safer alternative to ephedra due to its unique ability to increase energy, boost metabolism, and suppress appetite.

Guarana Extract

This coffee-like herb helps speed up metabolism and enhances endurance and stamina. It also slows down the appetite.

Backed by scientific studies and research, HCA allows you to lose weight naturally!

Our Verdict

After reviewing the different aspects of Clenbutrol, we gave it an above average rating and it deserves to be on of the top 5 fat burners at the moment.

The ingredients and their quantities are clearly shown on the label and the 3 main ingredients are proven and natural weight loss ingredients.

Best Fat Burner Thermogenic

There is no caffeine in this formula, but Guarana content is decent and they have similar effects.

In addition to this, there are no harmful ingredients in the product, so there is a lower risk of side effects. The dosage is easy to stick to.

Conclusion

Even though there is quite the variety of fat burner pills available at your local drugstores, supermarkets or health food stores, as well as even more options online, it doesn’t mean that every option is going to be right for you.

To get to our top 5, we’ve reviewed a number of fat burner products out there looking at their ingredients, their benefits, and potential side effects and whether they are worth buying. So here are a few “DOS” and “DON’TS” we followed to select these products.

What to search for in the best fat burner pills?

Contains natural, safe and proven thermogenic ingredients

Choose products that contain natural and safe fat burners like green tea, caffeine, capsicum or cayenne extract. These are proven thermogenic ingredients with plenty of research showing their effectiveness as a thermogenic – increasing your body’s own metabolism, allowing it to burn more fat.

Contains natural, safe and proven appetite suppressants. An effective fat burner doesn’t just increase your metabolism to burn more fat, but also keeps your appetite under control.

Keeping those cravings at bay will mean you’ll achieve results faster. Glucomannan is one of the most effective, proven natural appetite suppressant out there. Look out for this on the product labels.

Contains sufficient amounts of the ingredients. Once you’ve got the right mix of ingredients it’s key that the product contains the right amounts of them. If they contain too little you will not see results.

For optimum results, the green tea contents should be at least around 500 mg per daily serving whereas caffeine content needs to be at least around 200-300 mg per daily serving.

Each ingredient and their amounts are clearly stated on the label.

There’s nothing worse than spending your money on products that you’re not sure what they contain. You may spend your money on completely useless ingredients and what is worse they may even be harmful for your health. Always choose a product that clearly displays the ingredients and their amounts on the label.

What to avoid in a natural fat burner?

Proprietary blend – you can’t trust companies that hide their ingredients.

Products that contain any ingredients associated with nasty side effects.

Products that contain a lot of useless fillers – ingredients that have no or very little effect.

In short

Check the ingredients and their amounts contained by the product before you buy. Good natural fat burners will not be hiding behind proprietary blends.

Go for fat burners that contain both proven thermogenic ingredients and proven appetite suppressants and check that the amounts of different ingredients are substantial enough to have any impact.

Finally, avoid products with questionable ingredients that may cause some nasty side effects. If you follow these simple rules you can’t go wrong.

Our top recommendation, PrimeShred is a natural fat burner that ticks all these boxes.

Although we recommend PrimeShred as the best fat burner pills to those who are interested in losing weight quickly and safely, it is important that you evaluate your lifestyle so that you know what you want from your weight loss supplement.

Whether it’s an appetite suppressant, metabolism booster, workout enhancer, etc. so that you at least know what you’re looking for.

After you’ve decided that, you may want to consider these ingredients or products that we’ve reviewed and found to be successful. That way you can find which the best fat burner pills for your individual lifestyle!

In the end, supplements should never be taken in place of a healthy diet and regular physical activity. You should always aim to get these two key pillars right first.
