If you are a weight-conscious person, you must have heard about L-carnitine. It is a popular ingredient of fat-burning tablets and weight-loss supplements. L-carnitine is produced in the human liver, brain, and kidneys. It’s a chemical that assists the fat-burning process in the body. L-carnitine plays a significant role in fat metabolism and energy production. It is essential for proper brain function, heart function, muscle movement, and the health of skeletal muscle and other processes of the body.
L-carnitine helps increase the L-carnitine levels in individuals with low levels. The human body transforms L-carnitine into other chemicals known as propionyl-L-carnitine and acetyl-L-carnitine. Some people take it for heart, blood vessel, kidney-related conditions, and cardiovascular disease, and even many other medical conditions.
L-carnitine has a major role in fat metabolism and energy production as it carries long-chain fatty acids and transports them to mitochondria (the powerhouse of cells), where these acids get oxidized and produce energy. This entire process is called beta-oxidation, which is essential for ATP generation and fat oxidation, the primary source of energy for cells.
L-carnitine is prominently known to help energy balance maintenance in the body and can influence fat utilization for energy production, potentially aiding in reducing insulin resistance which may impact exercise performance and weight management.
In this blog we will explore and talk about L-carnitine for fat loss uses, its right dosage, how it works, benefits, and possible side effects, supported by clinical evidence . Keep reading to get the all essential information about L-carnitine.
L-carnitine is a derivative of amino acids that are naturally found in the human body. So basically, L-carnitine is also an amino acid formed inside the body. It is also found in some foods and health supplements. It offers many health benefits such as better brain function, weight management, and enhancing the body's carnitine pool a lot more.
L-carnitine naturally occurs in the body and is usually consumed by people in the form of a supplement. It can be considered a nutrient as well as a dietary supplement, as it is formed from the amino acid lysine. It has a crucial role in energy production by carrying fatty acids to mitochondria. Mitochondria are like an engine within the cells that burn fat to produce usable energy.
The human body can form L-carnitine from lysine and methionine (amino acids). The body requires plenty of vitamin C to form a sufficient amount of L-carnitine. More than 95% of it is stored in muscles and trace amounts are found in blood, heart, liver, and kidneys. Small amounts of L-carnitine can be obtained by consuming animal products such as dairy products and meat.
Individuals who only consume plant-based diets or patients experiencing certain genetic problems may not be able to create and get adequate L-carnitine, making it a conditionally essential nutrient. In India, Supplemental carnitine is accessible in different forms such as tablets, capsules, and liquids, especially for those with renal disease.
L-carnitine supplements are available in various forms, including:
L-carnitine is a fatty acid derivative that is formed in the human body. It assists the fat metabolism and the process of energy formation, along with many other processes. L-carnitine is known to support and manage weight loss, improve brain function, and help disease prevention. It is naturally produced inside the body and found in dairy products, meat, etc. People with lower levels of L-carnitine, such as vegetarians, vegans, and older adults, can benefit from supplements.
L-carnitine supplements may aid weight management and fat loss, especially in obese diabetic patients and overweight individuals. It can potentially reduce fat mass, BMI (body mass index), and body weight. Consuming L-carnitine supplements solely may offer modest weight loss benefits; however, consuming it with exercise and a healthy weight loss-friendly diet can be more effective. It supports the oxidation process of fatty acids which reduces the stored fat by burning it leading to weight loss.
L-carnitine supplements are popular among athletes and individuals looking to enhance their physical performance and endurance. It is known to promote energy production as it transports fatty acids to the powerhouse of cells (mitochondria) where these are burned to form fuel.
L-carnitine can reduce soreness and fatigue in muscles by preventing lactic acid buildup and enhancing oxygen supply to muscles. It transports the fatty acids to mitochondria which helps muscle recovery by reducing muscle damage, and soreness and improving recovery time pose workout. L-carnitine supplements reduce markers of muscle damage (creatine kinase and myoglobin).
L-carnitine is not directly associated with overall metabolism; however, it has a significant role in fat metabolism and energy formation, which is indirectly associated with better physical performance and weight management. It improves fat burning and aids weight management, particularly when consumed in combination with a healthy diet and exercise. So, L-carnitine supports fat metabolism, not overall metabolism, and supports weight management indirectly.
This particular supplement most efficiently supports exercise performance and complete fitness. Various studies performed to evaluate the fitness advantages of L-carnitine L-Tartrate supplement have revealed that it enhances muscular endurance, which means you can lift for extended periods during the workout.
It also helps muscle growth and recovery, offering benefits for athletes and muscle builders as it efficiently promotes muscle build-up. It enhances blood flow and nutrient transportation in muscles, preventing exercise-related muscle damage.
Consuming oral L-carnitine supplementation or administration by IV can enhance exercise tolerance in individuals with chest pain issues. Taking this supplement in combination with the standard L-carnitine treatment can ease chest pain and also improve the ability to exercise in individuals with cardiac syndrome accompanied by chest pain (no blocked arteries).
L-carnitine supplement administered orally or via IV can improve symptoms of heart failure and congestive heart failure (fluid buildup in the body). It can increase the ability to exercise in patients with heart failure.
The US FDA (Food and Drug Administration) approved using L-carnitine via IV (not orally) for patients with kidney failure and chronic kidney disease. IV administration should be done by medical professionals only; it is not for self-use.
L-carnitine supplementation is believed to treat myocarditis and swelling of the heart. Children with diphtheria are likely to develop myocarditis (inflammation or swelling of the heart). Oral DL-carnitine can reduce the likelihood of developing myocarditis in kids and associated deaths.
These are potential benefits of L-carnitine supplements; however, sufficient reliable information is not available yet, and more research is required. It is advised to seek advice from your healthcare provider before taking any supplements.
The supplementation is known to support fat-burning processes, contributing to fat loss. It helps bring more fatty acids to cells so that more fat can be burned. L-carnitine may support weight loss in many people; still, it is advised to talk to a dietitian or medical professional to create a thorough exercise and diet plan to improve the outcomes. Further research is required to determine how the supplement may help long-term weight loss and management.
A study performed in 2020 found that L-carnitine supplements essentially reduce body weight, fat mass, and body mass index. However, it is not known to influence belly fat, particularly or the percentage of body fat.
Another study performed in 2021 with 1239 individuals suffering from type 2 diabetes revealed that consuming 2 grams of L-carnitine supplement daily for 2 weeks promoted noticeable weight loss.
A systematic review and meta-analysis to evaluate the effects of L-carnitine supplements on weight loss was conducted with dose-response analysis. This study aimed to investigate the impact of L-carnitine on body weight and composition through the maximum number of randomized controlled trials and to perform a dose-response analysis.
The meta analysis found that L-carnitine supplement noticeably reduces body weight, body mass index, and fat mass. No considerable impact was found for body fat percent and waist circumference. The conclusion is that L-carnitine supplement has a modest impact on weight loss, particularly among obese and overweight adults.
A lot of people prefer taking the supplement before a workout or on an empty stomach. The scientific studies advise taking an L-carnitine supplement around an hour before the workout or exercise. However, if you are seeking weight loss support or muscle recovery, you can take the benefits of the supplement by consuming it after exercise; it will still be effective. L-carnitine weight loss results should be realistic. It may not give significant results if you are taking it solely. However, combining the supplement with a suitable diet and exercise can offer remarkable benefits.
The typical recommended L-carnitine dosage for weight loss ranges between 500 mg to 2,000 mg per day. L Carnitine weight loss dosage recommendation may vary from person to person depending on certain factors such as age, gender, and health condition. The exact dosage may also vary depending on the form of supplement such as tablet, injection, or tartrate.
Usually, the adults are given 2 grams of L-carnitine by mouth per day. The recommended dose for children ranges between 50-100 mg per kg orally daily for up to one year. The right dose is decided by a healthcare provider depending on your particular condition.
Fat-burning supplements and tablets promote weight management by boosting metabolism, controlling appetite, and enhancing the oxidation of fat. Common ingredients found in weight loss supplements are L-carnitine, green tea extract, and caffeine.
Fat-burning supplements including L-carnitine-based ones do not work like a magic bullet. Most supplements have a modest impact on weight loss and these are most efficient when combined with regular exercise and a healthy diet.
It is extremely important to consult a healthcare professional before you start taking any supplement, particularly if you are taking certain medications or suffering from any health conditions. Talk to a doctor or dietician to get the right advice on starting any fat-burning supplement, especially those tested in randomized clinical trials. They will recommend the right supplement considering your particular health condition, body requirements, and expectations.
So, concludingly, fat-burning supplements such as L-carnitine can be significantly helpful to weight management, but they may work even better when taken responsibly under the guidance of a medical professional. Always remember that sustainable weight loss is equal to regular exercise, a healthy diet, and effective supplements.
Generally, men can burn fat more proficiently due to higher testosterone levels and higher muscle mass, which contribute to higher metabolic rates and rapid weight loss. On the other hand, women store more fat around the belly, thighs, and hips. Moreover, common hormonal fluctuations influence the fat-burning process. They require intense cardio to lose weight more efficiently.
Men naturally carry more muscle mass increasing their resting metabolism rate and allowing more calorie burn even when they are at rest. Higher testosterone levels in men encourage fat-burning and muscle growth allowing easier weight loss. As men have higher metabolic rates and muscle mass, they may experience rapid weight loss with regular exercise and dieting.
Women store more fat as compared to men, especially around thighs, hips, and breasts which is associated with reproductive processes. In women, progesterone and estrogen levels keep fluctuating throughout life due to menstruation, pregnancy, and menopause which also influence their fat storage and metabolism.
Studies found that women can burn fat more efficiently with regular exercise. Not always, but mostly women have slower metabolism rates because of a different hormonal status and lower muscle mass. Consistent hormonal fluctuations and patterns of fat storage can make it challenging for women to get rid of belly fat.
While looking for fat-burning supplements, do thorough research to evaluate their effectiveness, talk to healthcare professionals, and understand the safety and potential side effects. Check the ingredients, for example, green tea extract, soluble fiber, caffeine, and L-carnitine are proven ingredients. Always look for reputable and reliable brands.
If you are taking L-carnitine orally by mouth, you can safely take the supplement for up to a year.
Common side effects include:
In most cases taking L-carnitine supplement orally and properly as recommended (2g or less per day) is considered safe without any side effects. It is advised to avoid taking DL-carnitine and D carnitine supplements. These forms may block the effects of L-carnitine and cause symptoms that appear like L-carnitine deficiency.
L-carnitine deficiency occurs when your body doesn’t produce sufficient amounts of carnitine. It is a derivative of amino acids that is vital for fat metabolism and aids energy formation in cells. Carnitine deficiency may cause various health issues affecting heart and muscle function.
Carnitine deficiency can be caused by a genetic fault in the carnitine transporter protein, dietary issues, metabolic disorders, kidney dysfunction, liver conditions, and certain medications. Symptoms of deficiency include fatigue, heart muscle weakness, low blood sugar, vomiting, and muscle weakness.
Usually, the L-carnitine supplementation is prescribed by a medical professional to treat primary carnitine deficiency. It is also prescribed in cases where the deficiency is because of secondary complications of some inborn metabolic errors including fatty acid oxidation defects and organic acidaemias.
The injection is used as a fat-burning supplement. L-carnitine injection is administered intravenously under the supervision of a medical professional. It should not be administered at home without a trained professional.
Carnitine injection injection lets the amino acids get into the blood and improves lipid metabolism better. Injection works faster than the oral supplement. L-carnitine injection encourages the oxidation of fatty acid and boosts the fat-burning process.
L-carnitine is a derivative of amino acid, and it has a crucial role in fat-burning and energy-production processes of the body. The injectable supplement is used to manage many health conditions, such as heart and circulatory problems, and also to improve fitness and athletic performance.
The L-carnitine injection is intended to be used for the treatment of L-carnitine deficiency, including both primary and secondary carnitine deficiency. It is also used to treat certain metabolic disorders (mitochondrial disorders and fatty acid oxidation disorders).
L-carnitine is an amino acid derivative known to support brain function, weight loss, and disease prevention. The human body produces it naturally, and it is also found in dairy products and meat. Carnitine supplements may help people with lower levels of L-carnitine including vegans, vegetarians, and older adults. It is believed to improve the ability to exercise in people with chest pain, kidney failure, and heart failure.
Now concluding L-carnitine for fat loss. It significantly promotes fat loss by supporting the process of fatty acids reaching cells for energy creation. You may not notice evident weight loss by only taking a carnitine supplement, but combining the supplementation with regular exercise and a healthy diet can help you attain the desired weight. Make sure you follow your healthcare provider’s advice and recommendations.
L-carnitine is not directly associated with weight loss however, scientifically it reduces fat mass, enhances muscle mass, reduces fatigue, and encourages fat-burning processes that contribute to fat loss.
Some studies found that L-carnitine can help reduce body mass index, body weight, and belly fat in PCOS (polycystic ovary syndrome) patients. Pregnant and breastfeeding women should speak to their doctor before taking an L-carnitine supplement.
Both L-carnitine and L-carnitine L-Tartrate are different derivatives of L-carnitine with different molecular structures and different benefits. L-carnitine transports fatty acids to mitochondria to promote energy production , and L-carnitine L-Tartrate combines L-carnitine with a potent antioxidant, tartaric acid. Both are associated with fat metabolism and energy formation.
The effects of carnitine supplements are usually evident after 2 months. When paired with routine exercise and a balanced diet, you may notice considerable improvement in body composition and weight loss.
It may work well with certain fat burners. Combining a carnitine supplement with a pre-workout supplement may boost the fat-burning activity. Creatine and carnitine supplements work more efficiently to enhance performance and recovery during high-intensity and strength training.
