L-Carnitine (100 Count)

L-Carnitine is a powerful, naturally occurring substance that helps turn fat into energy to power our cells. With every new study and experiment, it only becomes more clear how vital it is to our bodies overall. While the dietary L-Carnitine found in red meat (and in fish, poultry, dairy, and vegetables in much smaller amounts) is highly bioavailable, it sometimes isn’t sufficient for those with vegetarian diets, athletes looking for a boost, and others who need additional carnitine to deal with a carnitine deficiency or other serious medical issue.

If you need to shop for L-Carnitine online, you’ve come to the right place. This powerful energy- and brain-boosting supplement can help with everything from cardiac health to keeping your muscles limber, and Compounding Pharmacy of America makes it simple to buy L-Carnitine online. We are pleased to offer the best L-Carnitine supplements on the market in the form of 100 easy-to-swallow, vegetarian capsules loaded with 250 total mg of powerful L-Carnitine.

Our L-Carnitine product is produced by our trusted partners at Douglas Laboratories, who make every supplement to the maximum possible quality standards so you can buy it with confidence.

Note that Acetyl-L-Carnitine (500 mg, 60 capsules) is another essential, very similarly named Douglas Laboratories product that we also carry in our inventory. Acetyl-L-Carnitine is another top L-Carnitine supplement that may be of particular use to Multiple Sclerosis patients and others in need of a consistent but safe energy booster to combat fatigue symptoms.

What Is L-Carnitine?

L-Carnitine, sometimes called levocarnitine, is used to help the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes. This naturally occurring compound can be consumed as a part of your regular diet and purchased as a dietary supplement or be used as part of a daily therapeutic routine.

Naturally produced L-Carnitine plays a vital role in energy production within the human body and is actually produced in several different organs, including the brain, kidneys, and liver. L-Carnitine and other forms of Carnitine are amino acid derivatives produced by the synthesis of lysine and methionine. This nutrient helps your body convert fuel sources like fat into energy that your body can use, specifically by helping to carry fatty acids into the mitochondria, the so-called powerhouse of the cell. When our bodies do not make enough of this crucial substance, our bodies may struggle to get fatty acids into the mitochondria of our cells for conversion to energy. In turn, we may experience fatigue and other symptoms.

L-Carnitine as a Dietary Supplement

There are many reasons someone might turn to powerful, natural L-Carnitine when they need to add an energy booster to their daily routine of supplements and meds. Here are a few of the top therapeutic uses for our Douglas Laboratories L-Carnitine capsules.

Heart Health

Some studies into L-Carnatitine’s many uses have centered on cardiac health and patients with certain heart conditions. It is believed that L-Carnitine, taken as a supplement, may be able to help people suffering from angina (a specific type of chest pain) and may also be able to reduce the risk of further medical complications in the wake of a heart attack.

Research to further establish L-Carnitine’s effectiveness as a heart health booster is ongoing. In addition to cardiovascular disease, doctors and researchers have studied L-Cartinine’s potential in treating peripheral artery disease.

Neurological Health

L-Carnitine supplements have been studied for their potential to help patients struggling with Alzheimer’s disease and associated dementia. It is believed that managing the levels of the neurotransmitter acetylcholine may be essential to treating Alzheimer’s disease. L-Carnitine may also be important for the effective and efficient synthesis of acetylcholine.

Boosting L-Carnitine and acetylcholine levels may therefore help to alleviate some of the mitochondrial dysfunction and degeneration associated with Alzheimer’s and dementia. This is just one example of L-Carnitine’s far-reaching implications for all sorts of cellular functions within different regions of the body.

Athletic Edge

Some athletes and bodybuilders use L-Carnitine supplements to enhance their exercise routine, promote fat burning, or simply for getting a natural energy boost before a big event. L-Carnitine does not appear on the World Anti-Doping Agency’s list of prohibited substances, meaning it is not banned in any major sports leagues or well-regarded amateur associations.

Weight Loss

L-Carnitine is sometimes marketed as a weight loss supplement due to its role in transporting fatty acids. Because it helps move fat into the mitochondria to be “burned” as energy, it is thought that a greater concentration of L-Carnitine in the body may help stimulate and expedite this “fat-burning” process. Limited medical evidence is available to support the use of L-Carnitine as a weight-loss aid at this time, but some individuals have reported satisfactory results in their personal use of L-Carnitine as part of a weight-loss regimen.

Muscle Support

L-Carnitine’s fat-transporting mechanisms also play a role in how your muscles feel and how they recover after a hard workout. Healthy L-Carnitine levels are believed to protect your muscles from damage, such as that incurred by over-exercising.


L-Carnitine may also be useful for helping people manage Type 2 diabetes. This is because it is now believed that insulin resistance, which plays a key role in the development of Type 2 diabetes, could be closely associated with mitochondrial dysfunction and an inability to process certain fatty acids.


Because it helps move fuel into the cells’ mitochondria, L-Carnitine could arguably be called the “powerhouse of the powerhouse.” This is why its benefits are so very far-reaching. As it turns out, having healthy L-Carnitine levels may be important to all sorts of cells in your body, including those used in reproduction. Specifically, it has been studied for a potentially positive effect on sperm growth and motility.

Carnitine Deficiency

A deficiency of naturally occurring carnitines in the body, or primary carnitine deficiency, is one serious medical situation where L-Carnitine supplements may be recommended. Persons suffering from this rare genetic disorder can have difficulty producing enough L-Carnitine naturally, which, in turn, means that their bodies cannot “burn” certain fats effectively. It can also be used for treating secondary carnitine deficiency, a condition sometimes experienced by patients undergoing dialysis or going through other medical issues.

L-Carnitine FAQs

It’s important to do your research before you begin any new supplement. We know you may have questions about L-Carnitine that still haven’t been covered here. These are some of the most common inquiries about this wonderful and effective dietary supplement.

Q: How Does L-Carnitine Work?

A: L-Carnitine is an important, naturally-occurring amino acid derivative that plays a crucial role in energy metabolism and, in turn, many bodily functions. It performs this role by helping to transport fatty acids from your food intake into the mitochondria of your body’s cells. Here, those acids can be converted to the usable energy that keeps you going.

Q: Is L-Carnitine Safe To Take?

A: L-Carnitine is considered generally safe for most people to use when taken as directed. Just like any other supplement or medication, however, some people can experience unpleasant side effects when taking L-Carnitine. The most common are minor and include nausea and upset stomach, with some people also noting a change in body odor levels. Speak with a trusted doctor, nurse, or pharmacist to ensure that L-Carnitine won’t interact poorly with any of your current medications or treatments.

Q: Do I Need a Carnitine Supplement?

A: Many people have sufficient levels of naturally occurring carnitine in their bodies and are able to maintain this healthy level simply by eating carnitine-rich foods. Carnitine is mostly found in animal products, and red meat in particular. The carnitine values in other types of foods, such as dairy products or fruits, are negligible or nearly non-existent in the case of many grains and green veggies. This means anyone who avoids meat might want to consider a carnitine supplement. Because of the importance of carnitines in some of our most basic cellular functions, just about anyone can benefit from maintaining a healthier L-Carnitine level.

Q: Who Can Benefit from Taking L-Carnitine Supplements?

A: Many different people in many different health situations could potentially benefit from improved L-Carnitine levels. For starters, those with a medically diagnosed carnitine deficiency will be instructed by their doctor to find a supplement that works for them. Besides an actual carnitine deficiency, you might also want an L-Carnitine supplement if you are an athlete, frequent gym visitor, heart patient, or multiple sclerosis patient, among others.

Those who have experienced a recent heart attack or who have persistent angina can benefit from L-Carnitine supplementation. Athletes and anybody looking for a new workout-boosting supplement are also a primary market for L-Carnitine capsules. Finally, MS patients may experience improved muscular response with an L-Carnitine supplement.

Q: How Do I Use L-Carnitine Supplements?

A: To unlock the benefits of L-Carnitine in your own life, simply follow the dosing instructions on the label (or your doctor’s orders). Our Douglas Labs 250 mg capsule makes daily dosing easy, efficient, and discreet. If that doesn’t seem right for you, you might consider trying the 500 mg Acetyl L-Carnitine option, also from our trusted colleagues at Douglas Laboratories.
