L-Carnitine Supplements

L-Carnitine

Have you had a hard time making progress towards your fitness goals? There’s a great chance that the right supplement can help. L-carnitine is a proven supplement that helps you push past your plateaus! If you are looking for that extra edge to boost your life look no further.

What is L-Carnitine?

L-Carnitine is an amino acid. Your body uses Amino Acids for a lot of things. They can act as energy and keep your cells healthy. They can help fight diseases and will help you stay youthful. too You can get l-carnitine by eating meat or by taking a supplement. [1] L-carnitine is also an essential amino acid. This means that your body doesn’t make it naturally, and it is needed to perform. This means you need to get it from another source, whether it be from foods, supplements, or otherwise.

L-carnitine uses fat as a fuel source for your cells. When you exercise, your carnitine levels get depleted which makes you feel more fatigued. Supplementing with carnitine during your workouts will help keep your energy levels at a desired state.

How Does L-Carnitine Work in the Body?

Human Body

L-carnitine helps by transporting fat into your cells. Energy is made when it reaches your cells. When you are working out, your body needs more energy to perform. Without enough carnitine, you can experience a weakening of your muscles. L-carnitine has also been known to “keep blood glucose levels low, even after a carb-rich meal”. [2] This allows your body to hold more nutrients and recover faster.

Functions such as being able to burn fat, use energy, and have healthy muscles are needed to be healthy. L-carnitine plays a central role in contributing to your body in a positive way.

Burning fat will play a large role in boosting your mood. Having less fat will boost your self esteem and make you feel great. L-carnitine is the first step towards having the body you have always wanted.

What Happens to my Body if I Don’t have enough L-Carnitine?

An insufficient amount of L-Carnitine in the body can lead to many different problems. Some of these include:

  • Muscle Necrosis (atrophy)
  • Hypoglycemia (Low Blood Sugar)
  • Fatigue
  • Confusion
  • Cardiomyopathy (Heart Diseases)
  • Fatty Liver

These issues affect the muscles, the heart, energy levels, and morale. Over time, having low carnitine can wear your body down until you get sick. Rather than waiting for the problem to arise, it is always best to prevent the symptoms in the first place. [3] Avoiding these problems can help you stay positive and healthy. Nothing is more distracting and disappointing than sickness. With l-carnitne, you can combat these problems by keeping a healthy level in your system.

What types of Carnitine are there?

L-Carnitine is among the most well known. Acetyl-L-Carnitine, or ALCAR, is another form of this amino acid. ALCAR has been known to help those with Alzheimer’s disease. Memory and attention span improvement are ways in which this nutrient can help. ALCAR is also a natural super-antioxidant that helps to deliver energy to the brain.

ALCAR supplements can help maintain desired amino acid levels . Amino acids are the building blocks that help your body recover. Keeping a steady level of amino acids is necessary if you want to achieve fitness goals. ALCAR will allow you to stay balanced and healthy.

Carnitine tartrate is another form of carnitine. This source of Carnitine also plays an important role in producing energy for your body. Inside your cells, the products of energy can result in some unwanted compounds. Carnitine helps transport those toxins out of the cell.[4]

Many have concluded that regular l-carnitine is the best and most reliable form. Most of the research surrounding carnitine has been for l-carnitine. For this reason, it’s recommended that you take it over other forms. Although, those other forms can give benefits.

How Can L-Carnitine Help My Exercise Performance

Healthy

A 2011 study reported that supplementing with carnitine led to “55% less muscle glycogen usage, 44% lower muscle lactate, and other changes”. [4] These changes resulted in improved exercise performance. Less glycogen usage can result in longer endurance and overall physical performance. When you work out, your body gets energy from different storages. Glycogen is one of the first resources your body uses for quick energy. L-carnitine will make your body use less energy. Boost up the efficiency! This means that you can work just as hard but use less energy by supplementing with L-Carnitine.

Hitting plateaus can be frustrating when you are trying to get fit. A good supplement sometimes is all you need. Having energy will make working out easier. Oftentimes, plateaus can arise due to a lack of energy or motivation. Carnitine supplementation can help you push throuough fatigue. This allows you to make a proper push and continue on your journey to the healthy body you want. Who doesn’t want extra energy?

L-Carnitine and Heart Benefits

The heart is a muscle that needs energy and fuel to work. Carnitine is important for your heart because carnitine is important for energy. It’s typical for those who have heart issues to also have reduced carnitine levels.

Improved blood flow helps support healthy heart function and the proper transport of nutrients throughout the body. Your brain needs blood. So a healthy heart is good if you want to maintain your health. [5]

Heart failure is also a common health complication that can pose a risk to your well being. This happens when your heart loses its ability to pump blood to the places your body needs. Plaque can block your arteries and prevent proper circulation. Because the heart is a muscle, it is also has the potential to become fatigued. L-carnitine has been a standard preventative treatment in many medical studies. A study from Oregon State University reported that heart failure patients supplementing with l-carnitine had higher survival rates than those that didn’t. [6]

And in Italy, another study showed that l-carnitine supplements helped reduce levels of the inflammatory marker, C-reactive protein. This showed the potential to reduce cardiovascular risk in those with kidney problems. [7]

Heart disease is the single-largest cause of death in America. Issues with your body arise naturally. It’s always best to prevent those problems, if you can, before they start to affect you. Studies have shown how l-carnitine can help those who have heart issues. [8]

With so many different medications in the world today, it is easy to forget the basics. L-carnitine is a natural way you can help your body prevent heart issues. Keep in mind, l-carnitine will not fix your heart problems. However, the studies show that you will be better off taking l-carnitine.

L-Carnitine for Anti-Aging?

Anti-Aging

One of the main reasons we age is because the mitochondria in our cells start to break down. Carnitine can also help to increase mitochondrial lifetime. Some research suggests that Carnitine may have some anti-aging properties. [9] One study reported that rats dosed with acetyl-l-carnitine showed reduced mitochondrial decay. They also showed an improvement in memory-related tasks. [9]

If you are looking for a natural, safe, anti-aging supplement, this could be the supplement for you! Many anti-aging products can be unsafe, or ineffective. L-Carnitine directly helps your cells’ longevity, which will make your body last longer!

Your cellular age is one of the most important factors in age. Having healthy young cells is the key to longevity. The mitochondria is the most important part of the cell. L-carnitine supports the mitochondria which boosts cell health which will keep them young.

What Foods can I eat to get L-Carnitine?

Red Meat provides the most natural source of L-carnitine from foods. Beef provides 80mg in just 3 ounces. Dairy, poultry, and fish also contain carnitine. Milk has about 8mg per cup, chicken 1mg per ounce, and cod containing 1.67mg per ounce. If you do not consume meat, supplementing L-Carnitine is great to stay balanced. It is especially important for non-meat eaters to get carnitine in some form. It’s possible to get carnitine from sources other than meat. It can be difficult though because there isn’t as much in those sources. This is why it is especially important to supplement with carnitine if you don’t eat meat. Reduced levels of carnitine in the body lead to a whole host of issues. So supplement, if necessary.

What Are the Other Ways L-Carnitine is Good for my Body?

Carnitine supplementation can help memory problems among the elderly . Those who have used alcohol throughout their lives are more prone to suffer from memory loss and other mental issues. Carnitine supplementation can help improve your memory. If you have a loss of memory from alcohol, carnitine can help.

Men suffering from low testosterone can benefit from taking acetyl-l-carnitine combined with propionyl-l-carnitine. Sexual dysfunction, depression, and fatigue can all be helped with supplementation.

For athletes, you can be less sore after workouts. Post workout recovery in general can be boosted. Even an increase in nitric oxide production. [10] This means that L-carnitine can help you build muscle and increase strength. While you workout, L-carnitine gets rid of waste while you workout. This means that you can do more because you have less fatigue during your workout. This will also help how you feel after a workout.

Recent studies have shown that it is typical for those with kidney disease to also have an absence of carnitine in their body. Many kidney-related complications, such as heart disease, weakness, and fatigue, have been linked to this as well. One scientist discovered that taking an l-carnitine supplement improved the health of those suffering from the effects of certain kidney issues. [11]

You can’t put a price on a happiness and self-esteem. Whether you struggle with weight, or haven’t achieved the physical goals you want, l-carnitine can help. Many people struggle to find the right supplements that can help them make progress. Study after studies have shown that l-carnitne has a lot of benefits. All these benefits will make you feel and look great, and that is priceless.

L-Carnitine Side Effects

L-carnitine doesn’t have serious side effects. The mildest symptoms may include an upset stomach and vomiting. There have been virtually no reports of those who have suffered worse than that. Carnitine is in everyday foods which is why it is safe. There have not been any studies with regard to women who are pregnant. So as always, if you have any serious questions or concerns, speak to your doctor for advice.

L-Carnitine Dosage

For supplements, a 1 gram serving is typical. For those who have been diagnosed as l-carnitine deficient, one-gram servings, two to three times a day, is a typical recommendation. For chest pain and heart failure, one gram twice a day is a typical recommendation. For those who have just suffered a heart attack, two to six grams of l-carnitine every day is typical. [12] These numbers are just general ranges. As always, we recommend you consult your doctor before taking l-carnitine for a specific health benefit.

L-carnitine comes in liquid, tablet, and powder form. The results of supplementation for this amino acid, however, are all the same.

Because there are different forms of Carnitne, do your research beforehand. Reading the label and nutrition facts are the best ways to be sure you know what you are getting.
