The Best L-Carnitine Drinks of 2023

L-carnitine is an amino acid derivative that is naturally produced in our bodies. The main role of L-carnitine is to transport fatty acids into your cells’ mitochondria and convert those acids into energy. L-carnitine is also important for brain and heart function, mobility of muscles, and a range of other body processes.

The best source of L-carnitine is from animal products, such as meat, poultry and dairy. The highest concentrations of L-carnitine can be found in red meat. For instance, 2 ounces of cheddar cheese contain 2 mg of L-carnitine, 1 cup of milk contains 8 mg of L-carnitine, and 4 ounces of beefsteak contain 56 to 162 mg of L-carnitine.

Benefits of L-Carnitine

L-carnitine can help you in many different aspects, including muscle retention, energy, and fat loss. Below, we’re going to discuss some of the benefits L-carnitine has.

Longevity and Energy

L-carnitine is a chemical made in the kidneys, liver and brain that can help with transporting fatty acids in your body to the mitochondria, which then turns them into energy. Mitochondrial function can be improved through supplementation with L-carnitine. When it comes to regulating aging and immunity, the mitochondria are key, and they can help support both longevity and immunity.

Heart Disease

Even though the research is still ongoing, L-carnitine might help with some markers of heart health. Supplementation with L-carnitine can help with symptoms of heart failure, such as arrhythmia and chest pain, and it can boost circulation and heart health in the short period following a heart attack.

Improve Muscles

L-carnitine, and especially the form L-carnitine L-tartrate, can assist in reducing the muscle damage that happens during exercise. Not only will you gain a better capacity for fat-burning, but you will also have more energy for an active lifestyle and more efficient workouts. There are also studies that state that L-carnitine can help in building and retaining lean muscle among older people and that it has a favorable effect on fatigue. 

Moreover, when the levels of L-carnitine are higher, your body is more efficient when it comes to burning fat. This helps decrease visceral belly fat, which is the type of fat that surrounds your vital organs and can lead to serious health conditions such as fatty liver diseases. 

Side Effects

According to Healthline, the standard dose of L-carnitine is between 500 and 2,000 mg per day. L-carnitine is usually tolerated by most people. However, some might experience side effects while consuming L-carnitine.

These side effects include diarrhea, vomiting, nausea, and stomach cramps. In addition, some people might also experience a body odor that smells fishy, which can be pretty bothersome even though it’s not harmful.

Things to Consider When Buying L-Carnitine

In this section, we will talk about a few considerations you should keep in mind when you’re buying L-carnitine.


Before you start consuming any supplement, it is crucial that you exercise regularly and eat well. Supplementation won’t be able to cure anything if you do not have a healthy lifestyle.


When starting a product, it’s recommended to start with a lower dose and slowly build up to higher doses to see how your body reacts. L-carnitine can sometimes cause digestive side effects when it’s taken in higher doses, so you should start lower and work your way up.

Buying a product with a flexible dosage is smart. Flexible dosage means that the product is consumed by taking several capsules with smaller doses throughout the day instead of a product that has a single capsule with a high dose.


You have plenty of options to choose from when it comes to L-carnitine supplements, including tablets, liquid, capsules, and powder. The less commonly used option is tablets, while the most popular ones are liquid and powder. A liquid form is a great option for people who want to mix their L-carnitine with their shake or smoothie.


There are a few brands you can trust when you’re buying L-carnitine. If you’re making an online purchase, it is essential that you take into consideration who manufactures the product. We would recommend avoiding cheap prices that seem like they’re too good to be true, poor quality and unmarked packaging, and so on.

L-carnitine is an ingredient that needs proper care and handling, and manufacturers who don’t have experience or knowledge may use poor handling methods, cheap packaging, or the wrong type of storage, which can reduce the quality and potency of the supplement. Look for respectable brands that provide a specification of the ingredients used in their supplement and are transparent about their manufacturing processes.

Now you know everything you need to consider when you’re buying L-carnitine online, so you can make a well-informed decision.
