Obesity has become a worldwide epidemic in recent years, affecting people in all corners of the globe. Weight gain is not only detrimental to physical health but mental and emotional health as well.

Besides introducing some changes in diet and exercise plans, most people consider taking fat burner supplements as an efficient method for shedding the extra pounds. These nutritional formulas are believed to enhance metabolism, promote fat loss, boost energy, and improve circulation. Their benefits result from the miraculous combination of ingredients like caffeine, green tea leaves, and L-carnitine.

Should you decide to use such products, here is everything you need to know about their ingredients, dosage, cycle, and potential side effects.



Caffeine is doubtlessly the most widely used fat burner supplement due to its numerous physical and mental health benefits. Its role as a stimulant of the central nervous system enables caffeine to reach the brain incredibly fast in order to improve alertness. Read more about the effects of this ingredient on your body.

Moreover, caffeine provides users with an immediate energy boost and significantly reduced fatigue, which is of great importance for individuals performing physical exercise. Adenosine, a molecule produced in the brain, is the main culprit for promoting sleepiness. However, by binding with the adenosine receptors, caffeine prevents the production of this molecule, thus increasing wakefulness. As a result, users feel impressively energetic owing to the increased secretion of dopamine and glutamate, the chemicals responsible for inducing energy.

By boosting stamina and reducing tiredness, caffeine automatically aids gym-goers to endure much longer and intense workouts. The more arduous the workouts the greater amount of fat people burn while training. Besides inducing the natural process of fat loss, caffeine is also capable of enhancing the work of metabolism, which is responsible for converting calories into energy.

While taking fat burners with caffeine, users are strongly advised to restrict the daily intake of this ingredient to avoid potential side effects, such as insomnia. Make sure you limit the consumption of coffee, energy drinks, sodas, green tea, black tea, and chocolate, as these products are considered to be high caffeine foods and drinks. Also, you’re recommended to take the last dose of the supplement at least six hours before bedtime.


L-Carnitine is another popular fat burner option, used for its fat-burning and performance-enhancing qualities. This substance is an amino acid, which is comprised of lysine and methionine and stored in skeletal muscles. The primary role of L-carnitine is transporting fatty acids to the mitochondria of cells, where fat is converted into energy.

Therefore, L-carnitine supplements are crucial for gym-goers whose bodies don’t produce enough quantity of this substance, thus failing to transport the fat to the intended destination. Fortunately, these supplements stimulate the transportation of fatty acids to cells’ mitochondria, which considerably aids the fat-burning process. Additionally, this supplement increases blood flow and circulation whose job is to transport oxygen and nutrients to muscle cells.

Upon determining the dosage of L-Carnitine supplements, bear in mind that your body produces this amino acid naturally. Also, it can be consumed through food sources such as pork, beef, chicken, fish, and milk.

Green Tea

Green Tea

Besides being a popular beverage, green tea is known to be an effective far burner supplement as well. Its leaves contain catechins, which are extremely beneficial in burning abdominal fat. These substances block the body enzyme that is responsible for preventing the secretion of adrenaline and noradrenaline. Once catechins block this enzyme, users experience an increase in metabolic rate and an improved fat-burning process.

Since epigallocatechin (EGCG) is considered to be the most effective catechin of green tea, nearly all supplements include EGCG as one of the main ingredients. Apart from epigallocatechin, green tea leaves also contain caffeine, which additionally stimulates the process of weight loss.

Dosage and cycle

Although cycling fat burner supplements aren’t as common as cycling steroids, users are encouraged to cycle these products for achieving better results. For instance, the optimal cycle for taking any type of these supplements is a period of four to six weeks, followed by a few weeks break. In the course of the break period, users are likely to experience caffeine withdrawal symptoms that might last up to a week.

In terms of dosage, it’s paramount for users to follow the package guidelines, provided by the manufacturer. Make sure you commence the cycle at a low dose during the first two weeks, which you can gradually increase in accordance with your fitness goal. Anyhow, the maximal recommended dosage isn’t supposed to be exceeded.

Considering the wide range of stimulants fat burners contain, these formulas shouldn’t be taken after lunchtime, as they’ll probably affect your sleep quality. Therefore, you’re expected to take the recommended doses prior to having your breakfast and lunch.

Potential side effects

Despite their multiple benefits, fat burners might cause potential side effects, particularly when surpassing the recommended dosage. Due to their increasing effect on cortisol, the stress hormone, these supplements are likely to increase anxiety. Additionally, their role in the stimulation of the central nervous system might result in a fast heart rate, which leads to sleep deprivation.

Moreover, due to the increased metabolic rate, some individuals might experience hypertension, otherwise known as high blood pressure. Digestive issues are also common among users, who usually experience diarrhea, bloating, constipation, and change in bowel habits. Click here to check out the most common digestive conditions.

Regarding emotional health, users might be subjected to certain behavioral changes when taking fat burners, such as experiencing frequent mood swings as well as becoming more irritable, aggressive, and nervous. Upon noticing any of the above-mentioned side effects, make sure you stop using the product or reduce the dosage.
