Top 10 Reasons to Use Carnitine

Top 10 Reasons to Use Carnitine

Taking carnitine with omega-3 fish oil is one of the simplest things you can do to improve body composition and raise your energy levels. The cool thing about carnitine is that by elevating the amount of carnitine stored in your muscles, you will see improvements in your quality of life.

A healthier body composition and more energy are two of these benefits, but taking carnitine is known to improve all of the following:

  • High-intensity work capacity
  • Increase athletic performance
  • Speed recovery from intense exercise
  • Make your brain work better
  • Prevent oxidative stress that leads to longer term health problems such as cardiovascular disease, diabetes, and chronic inflammation

A study in The Journal of Physiology provides groundbreaking evidence that carnitine supplementation can improve athletic performance, something that researchers have had trouble proving for years.

This article will discuss the top ten health benefits of elevating your carnitine levels with a focus on achieving optimal body composition.

1) Take Carnitine to Burn Fat: The Basics

Carnitine is an amino acid composite that is made from lysine and methionine. There are a couple of different forms of carnitine, such as acetyl-L-carnitine and L-carnitine tartrate, and we’ll look at which forms you should be taking and when. In this article, unless otherwise stated, “carnitine” will be used to refer to L-carnitine tartrate.

Carnitine is a potent fat burner because it is responsible for the transport of fats into the cells to be used for energy in the body. By raising the level of muscle carnitine, you support the fat burning process, and because your body becomes more efficient at processing fuel, it will increase your energy levels.

Elevating carnitine will also improve physical performance by burning more fat, sparing glycogen, clearing muscle lactate, and optimizing hormone levels.

2) Pair Carnitine and Omega-3 Fish Oils

For carnitine to be effective, you need to ensure you eat adequate levels of omega-3 fatty acids.

Omega-3 fatty acids are important because they will improve the health of every cell in your body if you get the right amount of them. The cells are made up of two layers of lipids or fats, which will be composed of healthy or unhealthy fats depending on the type you eat.

If the cell lipid layers are made up of omega-3 fats, the cell will be generally healthier, and it will also make them more sensitive to insulin. Having your cells be more sensitive to insulin allows your body to get the most energy production out of carnitine.

Omega-3s increase metabolic rate by increasing cell activity and fat burning. Carnitine is the delivery system for long chain fatty acids such that the less carnitine you have in the body, the fewer fatty acids that get into the cell, meaning you don’t burn them for energy.

Instead, the fatty acids go into a depository and are stored as fat. By elevating carnitine, fat burning increases and you give the cell the right genetic machinery to raise metabolism. You’ll have more energy, feel more motivated, and any excess fat begins to come off.

3) No Need For Carbs: Pair Carnitine with Omega-3s for Fat Loss

The new study in The Journal of Physiology, which we will highlight below starting with #5, showed that taking carnitine with carbs is effective for elevating muscle carnitine levels and improving athletic performance.

But carbs aren’t necessary as long as you get adequate omega-3s. A study in the Annals of Nutrition and Metabolism showed that combining carnitine, omega-3s, and polyphenols resulted in lower blood lipid levels and better cellular energy production, which has the implication of fat loss if the study had been of longer duration—it was only 12 weeks.

Researchers found that triglycerides were lowered by 24 percent and free fatty acids decreased by 29 percent compared to a placebo group that had no changes. These changes indicate healthier markers of cholesterol, better energy use, and fat burning that will lead to fat loss.

Additionally, genes that increase fat burning in the body were “activated” indicating a better metabolic profile. Take note that the polyphenols were included to raise antioxidant levels and fight oxidative stress that leads to chronic inflammation and poor cardiovascular health, among other things. They are not necessary for the carnitine to get to work.

4) Carnitine Fights Visceral Belly Fat

Visceral belly fat is one of the toughest fats to lose once you’ve got it, and it causes numerous health problems. Once you begin to gain visceral fat around the belly, it will lead to fat gain within the organs such as the liver, the heart, or even in muscle.

Fat gain in the liver leads to non-alcoholic fatty liver disease, while epicardial fat is a type of visceral fat that is deposited around the heart and is considered a metabolically active organ, altering heart function.

Raising your carnitine levels will fight this visceral fat gain because it increases fat burning, which has the effect of taking triglycerides and low-density lipoproteins out of the system so that they don’t build up causing high cholesterol and atherosclerosis. A new research study in the journal Food and Chemical Toxicology illustrates this.

Researchers gave a carnitine supplement to mice who were fed a high-fat diet in order to make them gain weight. In comparison to a group of mice fed a placebo, the carnitine group gained substantially less visceral and subcutaneous fat (fat that is right below the surface of the skin that you can pinch with your fingers). The placebo group exhibited the beginning stages of non-alcoholic fatty liver disease and atherosclerosis, neither of which were evident in the carnitine group.

5) Take Carnitine To Improve Performance

The study in The Journal of Physiology is the first to show that muscle carnitine content can be increased in humans through diet. Once carnitine is elevated, metabolism in the body is dependent on the intensity of exercise, allowing for better energy use and performance.

Researchers gave a placebo or a supplement of carnitine tartrate and carbs (2 g carnitine with 80 g of carbs twice a day) to experienced athletes who were training for a triathlon three to five times a week. At various points throughout the study subjects performed the following exercise tests: two thirty-minute repeated bouts of exercise (the first at 50 percent of maximal oxygen uptake and the second at 80 percent), followed by an all-out 30-minute performance trial.

After 24 weeks of supplementation, the carnitine group increased performance from baseline by 11 percent in the exercise trials compared to no improvement in the placebo group. Participants who took carnitine also rated the trial and the exercise bout they performed at 80 percent of max to be easier than at baseline, while the placebo had no difference in rating of perceived exertion (RPE).

Two key points from this study are essential for making carnitine supplementation effective at elevating performance. First, it takes a long supplementation period to raise muscle carnitine levels and reap the benefits of improved energy production. In this study after three months there were no changes in performance or RPE from baseline, but after 6 months those improvements were pronounced and statistically significant.

Second, carnitine doesn’t optimally accumulate or “load” in muscle unless accompanied by high insulin concentrations. This explains why many previous studies have NOT shown increases in muscle carnitine after taking it in multi-gram doses.

In this study the carnitine was taken with carbs because the carbs triggered insulin release, which allowed the carnitine to load into the muscle. There is a big focus in the health world on minimizing insulin secretion from carbs for optimal body composition. This is critical, but be aware that insulin is actually a potent anabolic hormone if the cells are sensitive to it and if appropriate levels are present.

Pairing carnitine with carbs is one option, but as shown in #3, carnitine can also be paired with omega-3s, which may be more appropriate for individuals whose primary goal is to lose fat.

6) Increase Work Capacity With Carnitine

Another benefit of raising carnitine levels is that you’ll have a greater work capacity, but it will not feel as physically difficult. You’ll be able to lift more weight, complete more reps, or run faster and longer, but with more ease.

This is because higher muscle carnitine levels help decreases pain, muscle damage, and markers of metabolic stress from high-intensity exercise by decreasing lactic acid production.

A higher level of carnitine increases energy production, but it also has the effect of accelerating muscle buffering by maintaining the pH of the muscle and minimizing the accumulation of hydrogen ions. Basically, carnitine helps eliminate the byproducts of intense exercise that cause pain and muscle damage (the burning you may feel when training hard), allowing you to work harder.

In the Journal of Physiology study, results show how higher muscle carnitine levels increase work capacity by reducing lactate accumulation in the muscles. Following the exercise bout at 80 percent of maximal, muscle lactate buildup was 44 percent lower in participants that supplemented with carnitine compared to the control group.

Following the exercise bout at 50 percent of maximal, the carnitine group used 55 percent less muscle glycogen than the control group indicating that they burned more fat for fuel and had improved energy production.

The combination of less lactate buildup and greater fat burning in the two exercise bouts allowed the carnitine group to increase work output by 35 percent, while having a lower RPE. In simple terms, taking carnitine is a no-brainer if you want to improve body composition by burning more fat and be able to train at a higher level!

7) Enhance Recovery with Carnitine

Take carnitine to speed both short- and long-term recovery from intense training and you’ll have less pain, soreness, and feel more energized. Muscle lactate buildup is a limiting factor that inhibits performance and causes muscle pain, meaning that if you produce less of it and are able to clear it faster, you will have a faster recovery.

Taking carnitine will also support an anabolic response to exercise by up-regulating the androgen receptors, which will “help to mediate quicker recovery,” according to one research group.

A study led by William J. Kraemer found that supplementing with carnitine for 21 days produced an increase in the resting content of the androgen receptors that bind with testosterone, indicating a better anabolic environment.

Following resistance exercise, participants also had increased androgen receptor content that indicated greater cellular uptake of testosterone and increased protein synthesis. Enhanced protein synthesis allows tissue that was damaged during training to regenerate faster and speed recovery.

Researchers suggest carnitine supplementation helps promote recovery by producing “more undamaged tissue, (and a) greater number of intact receptors that would be available for hormonal interactions.”

8) Improve Cognitive Performance with Acetyl-L-Carnitine and Increase Motivation

A form of carnitine called acetyl-l-carnitine will give you superior brain function and increase motivation, meaning it’s super useful for people who want to lose weight but feel unmotivated to exercise.

Acetyl-l-carnitine is a powerful antioxidant and can help reduce buildup of heavy metals in the brain. Pairing it with Alpha Lipoic Acid and DHA will support dopamine levels, while increasing attention span and motivation.

For depressed people or those who need to lose weight, it works wonders on motivation and self-initiative, both with training and work-related tasks. And by taking acetyl-l-carnitine, you’ll still benefit from improved energy, physical performance, work capacity, and a speedy recovery, all benefits to help you achieve a lean physique.

A number of research studies support the use of acetyl-l-carnitine for a better brain. For example, a new study in the Scandinavian Journal of Gastroenterology found that giving patients with liver dysfunction acetyl-l-carnitine significantly improved their physical function, general health, overall mood, and well-being. They also reported less depression and anxiety.

9) Prevent Type 2 Diabetes and Improve Insulin Health With Carnitine

Carnitine is emerging as a supplement that can help prevent type 2 diabetes because of how it improves fat metabolism. It can counter the diseases of metabolic syndrome by preventing atherosclerosis, and supporting cardiovascular health, while inducing fat loss.

Plus, raising carnitine levels will fight related type 2 diabetes factors because it has antioxidant properties, meaning it abolishes free radicals and reduces oxidative stress. The key to improving your insulin health and losing fat with carnitine is to understand that the following interrelated factors must be present for this method to be effective:

A) Get adequate omega-3 fish oils.

B) Be consistent with supplementation and give it time.

C) A high-protein diet and exercise will make it much more effective

10) Use Carnitine for Better Skin

A topical carnitine cream can improve the health of your skin by decreasing the amount of oil released by the pores. A new study in the Journal of Cosmetic Dermatology found that a carnitine cream increased the amount of fat that entered the cell, which decreased the oil secreted by the skin.

This led to less oily skin and a smoother overall appearance. It also indicates the value of using carnitine to improve the transport of carnitine across the cellular wall to be burned for fat because Beta fat oxidation, or burning, was enhanced.

How To Take Carnitine

Carnitine tartrate is the most common form for improving exercise performance, but there is evidence that a blended form that contains acetyl-l-carnitine can be just as effective while supporting mood, cognition, and cardiovascular function. Adding a third form, propionyl l-carnitine, will improve blood flow, support cardiovascular health, and benefit gut health. We offer all three in our Carnitine Synergy, which also combines the thermogenic green tea extract with the brain support amino acid acetyl-l-tyrosine to help you take your training to the next level.

For improvements in exercise performance, studies show benefits from 2 to 4 grams of carnitine a day, often taken in divided doses, such as 2 grams at breakfast, and 2 grams post-workout. For cognitive and metabolic benefits, 1 to 4 grams a day in divided doses may be helpful.
