Best L-Carnitine Supplements

Amino acids are the building blocks of the body. You may be recognizable with many of them that are essential for optimal health. But some, like L-Carnitine Supplements, can sometimes be beyond.

L-carnitine is only found in very small amounts in exact foods like fish, chicken, and beef, and, probably, you aren’t getting enough of it in your diet. An l-carnitine supplement can simply fix that by providing you with a consistent amount of this vital amino acid that has some pretty awesome benefits.

L-carnitine supplements do accurately what you expect from them – they help you turn fat into energy! It looks too good to be true, right? Now that you’re re-familiarized with the reason of l-carnitine, let’s learn about it more and have a seem at some of the best l-carnitine supplements closer.

What is L-carnitine and what does it do?

This micronutrient derived from lysine and methionine is broadly known as a supplement but our bodies also naturally produce this essential nutrient through the liver and kidneys. It is connected to the B vitamins and is usually categorized as an amino acid, yet though it isn’t technically so.

Largely of the l-carnitine in your body will be stored in the muscles but there are also trace amounts in your blood and your liver. Its job in the body is to produce power and metabolize fat cells. This means that l-carnitine reasons your body to use fat cells for energy, burning them away. This is mostly done through mitochondrial transportation. Actually, this nutrient has earned its nickname, “the ferry”, since it acts as a carrier of fat.

You see, fatty acids cannot infuse the mitochondrial membrane. This is where l-carnitine arrives in to save the day. It acts as a shuttle, so to speak, to usher the fat cells into the mitochondria to be used as power.

Some people can find enough l-carnitine through their diet but others have a lack of l-carnitine. This creates this supplement as a “conditionally” important nutrient. Without enough of this nutrient in the body, serious health problems can occur for example stunted growth for children or muscle weakness in adults.

Sound like something you would like to take benefit of? This article will help you to get all the information you require to supplement with l-carnitine the most effective way.

What are the benefits of L-carnitine?

L-carnitine is a complex amino acid-like compound that has lots of added benefits. Though most people use l-carnitine as a weight loss supplement, many surprising added advantages come from the supplementation of this nutrient.

Increased endurance

Since this nutrient boosts the production of energy, l carnitine has been proven to prolong an athlete’s capability to perform. L-carnitine enlarges the blood flow to the muscle tissue acting as a sort of booster.

This makes it a huge supplement for any endurance athlete such as marathoners, swimmers, cyclists, and the like. This could also be helpful in athletes of competitive sports for example football or soccer, helping the athlete continues to play at a higher level because of their enduring energy levels.

Helps with weight loss

Many people swear by l carnitine’s ability to aid shed fat and overall body weight. Some studies have proved this to be right but other studies didn’t show the same effects. It may be a case by case basis, and we will seem further into this later on in this article.

Muscle gains

Studies explain that l-carnitine supplementation can also result in increased growth factors. L-carnitine boosts the binding proteins of a certain growth factor that is frankly related to muscle growth. This is particularly true of the older people where lack of l-carnitine in the body resulted in muscle atrophy. L-carnitine supplementation accreted that deficiency and helped muscle growth and strength.

A study also showed that supplementing with l-carnitine through long low-intensity workouts for example cycling or jogging; the body didn’t deplete the muscle tissues for power but instead tapped into the fat cells for energy. Many times it can be unsafe to engage in extensive low-intensity cardiovascular exercise since it can lower your metabolism. L-carnitine is proven to stop such metabolism loss.

Helps with recovery

L-carnitine can aid to reduce muscle soreness and speed up recovery time since it reduces muscular cell damage and the production of lactic acid. This will aid keep athletes performing at their best and have less need for downtime. Being able to find back to workouts quicker will also help the athlete to boost muscle endurance and strength.

Good for the brain

Depression takes shape in all different features of life. Dementia and Alzheimer’s are between those lists. Supplementation with l-carnitine (exclusively acetyl l-carnitine) has been proven to help treat depression symptoms in the elderly. It has also shown to develop memory and slow the brain’s cognitive refuse in those with Alzheimer’s.

Helps to regulate blood sugar

Insulin resistance is ongoing trouble for every walk of life. Some studies have shown that supplementing with l-carnitine can aid the body keep healthy blood sugar levels by improving insulin sensitivity and sugar uptake from the blood.

This can make huge improvements in the life of someone who has diabetes. Another study showed that l-carnitine supplementation too helps women who have polycystic ovary syndrome to lower their insulin struggle and glucose levels.

Helps male infertility

L-carnitine was given to 100 infertile men and it showed to develop the motility in the sperm. This may develop their chances of fertility.

It has also been proven that l-carnitine levels in the body are frankly related to the amount of testosterone in the body, rising sexual function. Another study explained that increased l-carnitine levels increased sperm count, attention, and mobility.

Can help fight fatigue

L-carnitine is useful in increasing energy levels and quality of life in the elderly and in those who have been through chemotherapy because of cancer and in those on dialysis.

Help with sleep apnea and narcolepsy

For those who endure from sleep apnea, their quality of sleep is poor since their breathing stops and starts during sleep, not allowing them to fall into a deep sleep.

With l-carnitine supplementation, the airway is extra open and breathing is easier. This results in improved sleep quality, which advantages overall health. Ironically enough, l-carnitine supplementation too improved the narcolepsy symptoms, resulting in less dosing off throughout the day in patients.

Good for heart-related issues

A review done by the Mayo Clinic showed an amazing reduction of heart-related matters by studying 13 different trials. The information studied showed that l-carnitine supplementation decreased ventricular arrhythmia and a 40% reduction of angina.

These are important numbers. Not only did this study show that it helped with heart-related issues, but it also showed to decrease all causes of death by 27%.

L-carnitine and weight loss

L-carnitine was THE fat burner before compost; thermogenic fat burners came on the market. Many individuals found these to be more effective in burning fat; however, they also arrive with many risky side effects. Some individuals just can’t handle the heart pumps these sometimes scary fat burners leave behind.

L-carnitine is back as one of the most accepted and non-stimulant fat burners existing on the market. This supplement is not only making a comeback but it is more understood and the products are extra pure and easier absorbed into the body.

It is improved to label l-carnitine a fat loss than a weight loss supplement. Since it will help in the intensity and endurance of your workouts, it will help you gain muscle so you may truly gain weight but it will be a clean bulking time where all your weight gained will be muscle and no fat. Certainly, don’t forget to take your BCAAs as well which are logically proven to incite muscle growth.

So if you are looking to get “cut”, desire those hard to get chiseled abs, and defined muscles, l-carnitine should be added to your supplementation.

As listed in the advantages of l-carnitine, there are so many factors that l-carnitine plays in the energy-burning process that will aid the body cut fat. It aids you to perform better during your workouts for longer periods, resulting in more calories being burned.

Since it protects the muscle tissues and transports fat into the mitochondria, it makes sure that those calories burned are all fat calories.

L-carnitine vs acetyl l-carnitine

These two amino acids are very similar to the names recommend, however, the way the body processes these nutrients direct to different final benefits. They can both be used to carry the cardiovascular and nervous systems, with protecting the muscles. But choosing between supplementing with l-carnitine or acetyl l-carnitine, relies on your main concern.

L-carnitine is a supplement that aids the body burn fat into energy more efficiently than acetyl l-carnitine. It will also assist in muscle endurance and physical performance.

Acetyl l-carnitine is more known for its cognitive healing. Since it has acetyl included in its chemical makeup, it can cross the blood-brain barrier and be used in this manner.

The question has been enquired whether you can supplement with both l-carnitine and acetyl l-carnitine simultaneously to advantage from both aspects of the spectrum. The short answer is that you can but in truth, it won’t do you much good. If you are looking for a supplement to aid sculpt a strong body, opt for l-carnitine since this will help you the most. If you require more memory support and brain protection, opt for acetyl l-carnitine.

How should I take L-carnitine?

L-carnitine can be taken in lots of different forms. The average consumer prefers capsules. These capsules typically contain between 200-500 mg of l-carnitine per capsules.

It can also be found in powder form which is desired for athletes as they can add it to their workout shake whenever it is suitable and it is believed to be absorbed more rapidly. Typically, one scoop contains about 500 mg but each product is different. Ensure you check the label if you choose this type of l-carnitine.

You can also get liquid forms of l-carnitine sold as a metabolism booster. These typically have high doses of l-carnitine. Many contain over 3000 mg per bottle. At this dosage, you possibly will be feeling some negative side effects.

When to take L-carnitine?

When and how to take l-carnitine is almost an accurate science. Absorption of l-carnitine can be tricky so it’s vital to take it at the right time and with the right aiders that aid the body in allowing l-carnitine to be engaged into the bloodstream and muscle tissue.

Because l-carnitine greatly helps decrease muscle soreness many individuals add it to their post-workout supplementation. It should always be consumed with high glycemic carbs since the insulin spike helps the body to absorb the l-carnitine. Many people also like to include protein in this stack to improve muscle growth.

It can also be consumed at any period of the day with a high carb meal if you want to break up your l-carnitine supplementation during the day.

How much L-carnitine should I take?

The suggested dosage of l-carnitine is 2 or 3 grams. You must get this with about 35 grams of high glycemic carbs and about 20 grams of protein. This should rather be a meal, as taking l-carnitine on an empty stomach can cause trouble stomach.

If you desire to supplement with acetyl l-carnitine as well, you can take this between meals on its own since its uptake is easier through the blood into the muscles and brain.

L-carnitine side effects and risks

People rarely bear from negative side effects when taking l-carnitine in the correct dosage, though, some people decide to overdo it and suffer the consequences. When taken in higher than suggested doses, you can have stomach issues for example cramping, diarrhea, nausea, and vomiting.

Those who bear from seizures and uremic patients should not take l-carnitine.

One study showed a probable link between l-carnitine consumption from red meat and atherosclerosis, a cardiovascular sickness caused by plaque buildup in the artery wall but this study was criticized due to the chronic amount of l-carnitine given to these subjects.

What to look for when buying L-carnitine?

No matter what form of l-carnitine you choose to buy, capsules, powder, or liquid there are some guidelines you should use before making the purchase.

First and foremost, your product should list the kind and amount of l-carnitine in each serving. Sometimes you can get l-carnitine products that contain other ingredients. If these ingredients aren’t something you identify or need, this product isn’t for you.

The best type of l-carnitine on the shop, the caviar of l-carnitine, is Carnipure. Search for the trademark on the label. This type of carnitine is truly l-carnitine tartrate but l-carnitine, l-carnitine tartrate, propionyl-l-carnitine are all very similar in makeup and likewise effective.

As with any supplement, ensure you are buying from a reputable company known for being trustworthy and takes their feature of product seriously.

Frequently Asked Questions About L-Carnitine Supplements

What is L-Carnitine?

Carnitine is a vitamin-like matter produced from amino acids within your body, and it plays a vital role in the production of energy. It can also be considered an amino acid since it is a dipeptide made from essential amino acids methionine and lysine. The name is derived from the Latin root “carnus” which is converted to “flesh.”It can be found in a few types of meat and dairy products, and every cell of the human body!

Two types of Carnitine exist L-Carnitine and D-Carnitine. The “D” form is not biologically active. This suggests that it can not be absorbed and used by the human body. L-Carnitine is the supplemental version of carnitine since it is the naturally occurring form and the most simply absorbed within the body when consumed like a supplement. L-Carnitine is biologically active. There are different types of Carnitine products that give the same carnitine benefits; with Acetyl-L-Carnitine being the most effective form.

matures that eat omnivorous diets will consume from 60 to 180 mg of Carnitine from their diet, but vegetarians and vegans consume just about 10 to 12 mg from certain plant-based sources for example asparagus. Your body also produces Carnitine. It is formed in the kidneys and the liver and stored in the heart, brain, skeletal muscles, and sperm. Its biological function is to convey fatty-acids, mostly long-chain fatty acids, into the mitochondria which are where they are oxidized to produce power for the body.

What Are L-Carnitine Supplements?

Carnitine supplements can be helpful for vegans, and strict dieters. Carnitine supplements have been studied since 1937 and can be found in pills, liquid, tablets, and quick-release gel capsules. There are three different regular types of carnitine used as supplements. This includes:

  • L-Carnitine-L-Tartrate – this type of carnitine supplement is fairly cheaper and gets into the bloodstream more rapidly. It does not absorb in the body any better than the other forms, but it is faster.
  • Glycine Propionyl L-Carnitine – This form has a unique capability to relax your arteries and enhance muscle pump. It boosts your body’s levels of nitrates which elevates the nitric oxide levels in the body. This shape also contains the antioxidant glycine.
  • Acetyl L-Carnitine – this form is the most simply absorbed by the body. It is carnitine with an acetyl group joined to the molecule. The acetyl group enhances its capability to transport across the blood-brain barrier, where it performs as a powerful antioxidant.

What Are the Benefits of L-Carnitine?

Overall, carnitine revitalizes your cells and aids your body function efficiently. When you age, the levels of carnitine within your body reduce and mitochondrial function is been decrease. The mitochondria are the powerhouses of our cells, and when the mitochondrial function of our cells is been reduce, we begin to age; like we are slowly losing power.

How Do I Take L-Carnitine?

For the advantages of carnitine supplementation, it has to be taken with food. Carnitine is mainly active when insulin levels are higher. Doses of 1-3 g are effective. When taking carnitine supplements, suggested nutritional intakes include:

  • 30 to 40 g of carbs
  • 20 to 40g of protein

Acetyl-L-Carnitine is more simply absorbed within the body and does not need to be consumed with food to maximize its advantages. You can take this form of Carnitine between meals.

Are There Any Side Effects of L-Carnitine?

If you are consuming it in truly high doses, which would be about 5 g or more per day, then it could probably give you diarrhea. Carnitine does interact with certain conditions though. Individuals with these conditions should consult a doctor before supplementing with Carnitine:

  • Cirrhosis
  • High blood pressure
  • A history of seizures
  • Type I diabetes
  • Peripheral vascular disease

There are a few rare side effects. These include:

  • Body odor
  • Increased appetite
  • Rash

Conclusion

Make no mistake, all the above supplements are brilliant carnitine providers. But, in my view, the best l-carnitine supplement of all is from Arazo Nutrition.

My reasons behind this decision?

It’s full of 1000 mg of the largely potent and fast-acting forms of all carnitine— l-carnitine tartrate. This makes it a great option for the serious gym-junkie—those looking for quick results and wanting to alleviate muscle pain so they can hit the training again as soon as probable.

With over two months’ supply, combined with an inexpensive price, this isn’t a product that will hurt the wallet.

Naturally, if you prefer a powder drink, or hope to concentrate more on brain-focus rather than fitness, one of the other products may be more proper.

But, for overall fitness and training performance, I consider the best l-carnitine product is Arazo Nutrition’s l-carnitine.
