1. L-Carnitine Boosts Brain Power
ALCAR, the supplemental form of L-carnitine, is present all over the central nervous system. There it is responsible for producing energy. It also produces a crucial neurotransmitter called acetylcholine.
The acetyl group linked to the carnitine molecule upgrades its potential to cross the blood-brain barrier and get into the brain.
Here it acts as a powerful antioxidant and achieves its potential as a protective agent against aging and neurodegeneration. Its blood-brain barrier crossing ability lets it support healthy blood flow to the brain.
In addition, ALCAR’s role in supporting healthy acetylcholine levels in the brain is very important.
This is because acetylcholine is crucial for learning, healthy memory, computation, perception, analysis and a number of other cognitive functions.
Along with supporting healthy acetylcholine levels, ALCAR’s antioxidant activity is helpful by reducing the signs of oxidative stress and removing toxins from the brain.
2. L-Carnitine Improves Physical Performance
When taken in the recommended dose, L-carnitine can improve your training, and by extension your physique.
It regulates energy by assisting the movement of fats across membranes within muscle mitochondria.
This happens in the case of both aerobic energy production, as well as recovery between anaerobic efforts.
L Carnitine Benefits
Muscle carnitine helps transport fatty acids into cellular mitochondria, but the pace at which this happens is based on carnitine availability in the muscles.
So the more carnitine there is, the more fat gets used during exercise as well as at rest. At the same time, this mechanism saves muscle glycogen stores thus prolonging endurance.
This carnitine derivative is also considered beneficial for athletes who want to prevent and protect against muscle damage.
On the flip side, a deficiency can mean that without sufficient L-carnitine, most dietary fats are unable to get into the mitochondria to be burnt for fuel.
Should this happen, which is fairly rare, it can potentially bring about muscle weakness, and a host of other problems.
3. L-Carnitine Helps With Weight Loss
One of the benefits that make L-carnitine weight loss a success story is that carnitine is a potent fat burner. Among other things, it transports fats to cells where they can be used for energy around the body.
With higher levels of carnitine stored in the muscles, the fat burning process is fuelled resulting in rapid fat loss and increased energy levels.
However, for L-carnitine weight loss to take effect it is important that there are adequate supplies of omega 3s in the body.
When partnered with omega 3s in the system, carnitine performance is boosted and the fat begins to come off faster.
As omega 3s are already responsible for expediting metabolic rate by accelerating cell activity that results in burning fat, when carnitine levels are increased in the body, the mechanism results in greater energy, and faster fat burn.
Another benefit of L-carnitine is that carnitine also targets visceral belly fat. This type of fat which starts to gather around the belly is not only the precursor of many health conditions but is also one of the most difficult types of fat to get rid of.
Fat accumulation around the belly will eventually lead to overall weight gain that impacts the performance of various organs like the heart, liver and different muscle groups.
To counter this, increasing carnitine levels can help promote fat burning and lowering cholesterol levels.
And since exercise is an important component of every weight loss regimen, it is important that individuals who want to lose weight and keep it off have the strength and stamina to work out regularly. This is another area where L-carnitine is very handy.
Carnitine can improve high-intensity performance and enhance athletic performance. Both practices enable individuals to work out harder and longer without too much physical difficulty.
Basically, it means that one can raise the bar for physical activity with a lot more ease when following an L-carnitine weight loss plan.
Carnitine will not only improve work capacity but also allow muscles to recover better and faster.
4. L-Carnitine Reduces Fatigue
This point pertains particularly to patients suffering from some kind of chronic disease that taxes their regular energy levels and brings on disease-related fatigue.
For instance, one study involving terminal cancer patients showed that patients receiving between 250 mg and 300 mg of carnitine three times daily improved fatigue and quality of life. 
Another study with cancer subjects showed that using carnitine supplementation at 4 grams a day mitigated fatigue in most patients receiving chemotherapy and restored normal carnitine blood levels. 
Likewise, one study presented evidence that patients with kidney disease receiving dialysis benefitted from carnitine supplementation.
This happened as those with kidney disease often suffer from anemia in which red blood cells (RBCs) can become deformed.
This deformity stops the RBCs from transporting sufficient oxygen to the body’s tissues, resulting in fatigue. Study results established that RBC deformity was reduced and RBC count increased after 3 months of carnitine supplementation. 
Yet another study on dialysis patients showed that carnitine, when administered in an injectable form, sustained higher oxygen levels.
This helped improve endurance during exercise while alleviating overall fatigue. 
5. L-Carnitine May Improve Mood
Given carnitine’s energy boosting and muscle fatigue potential, some experts believe that the same could also work to reduce depressive symptoms.
ALCAR has been used in a study to observe its anti-depressive effects in elderly patients suffering from age-associated depression. 
In another study, fibromyalgia patients were given ALCAR supplementation also showed improvements in depressive symptoms and reduced muscle pain.

6. L-Carnitine May Help Insulin Resistance
Insulin resistance occurs when the body’s cells are unable to use insulin effectively. When this happens, too much insulin in the system can present the risk of developing prediabetes and eventually, type 2 diabetes.
While there are many other factors, in one way, insulin resistance may be linked to the body’s inability to burn fat. When this happens, increased fat levels in lean tissue become an indicator of insulin resistance.
Research done in the area suggests that L-carnitine may improve insulin sensitivity by lowering the level of fats in muscle and lean tissue.
