L-carnitine is a popular supplement among fitness enthusiasts, athletes, and people who want to lose weight. But what is L-carnitine, and how does it work in your body? What are the potential benefits and side effects of taking L-carnitine supplements? And how much L-carnitine should you take for optimal results? In this article, we will answer these questions and more. We will also review some of the best L-carnitine supplements available in Singapore.
L-carnitine is a naturally occurring amino acid structure that the body produces. People can also get it from their diet or take it in the form of an oral supplement. L-carnitine is important for heart and brain function, muscle movement, and many other body processes.
L-carnitine’s main role in your body involves mitochondrial function and energy production. In cells, it helps transport fatty acids into the mitochondria, where they can be burned for energy. More than 95% of your L-carnitine stores are contained in your muscles, along with trace amounts in your blood, liver, heart, and kidneys.
L-carnitine is the standard biologically active form of carnitine, which is found in your body, foods, and most supplements. However, there are several other types of carnitine that have different effects on the body. Here are some of them:
For most people, acetyl-L-carnitine and L-carnitine seem to be the most effective for general use. However, you should always pick the form that’s best for your personal needs and goals.
L-carnitine plays a vital role in energy metabolism by facilitating the transport of fatty acids into the mitochondria. This process allows your cells to use fat as fuel instead of glucose or glycogen. This can have several benefits for your health and performance.
For example, by increasing fat oxidation, L-carnitine may help you burn more calories and lose weight. By sparing glycogen stores, L-carnitine may help you delay fatigue and improve endurance. By enhancing mitochondrial function, L-carnitine may help you prevent or treat various diseases that affect your heart, brain, muscles, kidneys, and liver.
L-carnitine may also have other roles in your body besides energy production. For instance, it may act as an antioxidant that protects your cells from free radical damage. It may also modulate your immune system and hormone levels. It may even influence your gene expression and epigenetics.
L-carnitine is a conditionally essential nutrient, meaning that your body can produce it in sufficient amounts under normal circumstances. However, some people may have low levels of L-carnitine due to genetic factors, aging, disease, medication, or dietary restrictions. In these cases, taking L-carnitine supplements may help restore normal levels and improve health outcomes.
Even if you have adequate levels of L-carnitine, you may still benefit from taking extra doses, especially if you want to enhance your physical or mental performance. Here are some of the potential benefits of L-carnitine supplementation:
L-carnitine may help you lose weight by increasing your fat burning and reducing your muscle breakdown. Several studies have shown that L-carnitine supplementation can increase the amount of fat you burn during exercise and at rest. This may result in a greater calorie deficit and more weight loss over time.
L-carnitine may also help you preserve your lean muscle mass while losing fat. This is important because muscle tissue is metabolically active and helps you maintain a higher metabolic rate. L-carnitine may prevent muscle breakdown by reducing the production of ammonia and lactate, which are byproducts of intense exercise that cause fatigue and soreness.
L-carnitine may help you improve your exercise performance by increasing your energy production and reducing your fatigue. Several studies have shown that L-carnitine supplementation can improve various aspects of physical performance, such as endurance, power, speed, strength, and recovery.
L-carnitine may enhance your exercise performance by increasing the availability of fatty acids as fuel for your muscles. This may spare your glycogen stores and delay the onset of exhaustion. L-carnitine may also increase the efficiency of your mitochondria and reduce the oxygen consumption of your muscles. This may improve your aerobic capacity and oxygen delivery to your tissues.
L-carnitine may help you reduce muscle soreness after exercise by reducing inflammation and promoting muscle recovery. Several studies have shown that L-carnitine supplementation can decrease the markers of muscle damage and inflammation, such as creatine kinase, lactate dehydrogenase, and C-reactive protein.
L-carnitine may also help you repair your muscle tissue faster and better by stimulating protein synthesis and growth hormone secretion. This may enhance your muscle growth and adaptation to training stimuli. L-carnitine may also prevent oxidative stress and cellular damage by acting as an antioxidant and scavenging free radicals.
L-carnitine may help you improve your heart health by reducing cholesterol levels and improving blood flow. Several studies have shown that L-carnitine supplementation can lower the levels of total cholesterol, LDL cholesterol (bad cholesterol), and triglycerides in the blood. This may reduce the risk of atherosclerosis and coronary artery disease.
L-carnitine may also help you improve your blood circulation by increasing the production of nitric oxide, which is a vasodilator that relaxes and widens your blood vessels. This may improve blood pressure and blood flow to your heart and other organs. L-carnitine may also protect your heart from ischemia-reperfusion injury, which is a condition that occurs when blood flow is restored after a period of low oxygen supply.
L-carnitine may help you reduce the risk of type 2 diabetes by improving insulin sensitivity and glucose metabolism. Several studies have shown that L-carnitine supplementation can improve glucose uptake and utilization by the muscles. This may lower blood sugar levels and prevent insulin resistance.
L-carnitine may also help you prevent or treat diabetic complications, such as neuropathy, nephropathy, retinopathy, and cardiomyopathy. These are conditions that affect the nerves, kidneys, eyes, and heart due to chronic high blood sugar levels. L-carnitine may prevent or reverse these complications by improving blood flow, reducing oxidative stress, and enhancing mitochondrial function.
L-carnitine may improve brain function by increasing the levels of acetylcholine, which is a neurotransmitter that is essential for memory and learning. L-carnitine may also increase the levels of dopamine, serotonin, and norepinephrine, which are neurotransmitters that regulate mood, motivation, and reward. L-carnitine may also protect the brain cells from oxidative stress, inflammation, and apoptosis.
Several studies have shown that L-carnitine supplementation can improve memory, attention, learning, mood, and mental clarity in people with Alzheimer’s disease, Parkinson’s disease, mild cognitive impairment, depression, or age-related cognitive decline.
L-carnitine is generally considered safe and well-tolerated when taken in recommended doses. However, some people may experience some minor side effects, such as:
These side effects are usually mild and transient, and can be avoided or reduced by taking L-carnitine with food or water, or by lowering the dosage. However, if you experience any severe or persistent side effects, you should stop taking L-carnitine and consult your doctor.
L-carnitine may also interact with some medications, such as anticoagulants, thyroid hormones, or chemotherapy drugs. Therefore, you should consult your doctor before taking L-carnitine if you are on any medication or have any medical condition.
The optimal dosage of L-carnitine depends on several factors, such as your age, weight, health status, and goals. However, based on the available research, here are some general guidelines for L-carnitine supplementation:
You can take L-carnitine at any time of the day, but some studies suggest that taking it before or after exercise may enhance its effects. You can also take it with or without food, but some studies suggest that taking it with a meal that contains carbohydrates and protein may increase its absorption.
