Acetyl L-Carnitine HCl (ALCAR). Lean & Fit. Upgrade Your Energy

Updated: 1/11/24

Have you ever felt sluggish even after a good night’s sleep? Stared at your overflowing to-do list and felt instantly overwhelmed? Longed to feel more energetic and able to tackle your tasks with ease? While we all have days like these, you don’t have to accept it as your new normal. I’m here today to tell you about an amazing supplement that may provide the boost you need – Acetyl-L-Carnitine, also known as ALCAR. ALCAR is a derivative form of the amino acid L-carnitine that supports natural energy production in the body. In this post, I’ll explain exactly what ALCAR is, the science behind how it works, and the benefits people commonly report when using it as part of a healthy lifestyle. 

What is Acetyl L-Carnitine? 

Acetyl L-Carnitine, or ALCAR, is a naturally occurring amino acid that is found in both plants and animals. It is a modified version of L-Carnitine, which is produced by the body and used to transport fatty acids into the mitochondria, where they are burned for energy. ALCAR is unique in that it also crosses the blood-brain barrier and can provide support for the brain.

One of the key ways that Acetyl L-Carnitine can benefit the brain is by increasing the production of a neurotransmitter, acetylcholine. This plays a crucial role in memory and learning, and can help to improve cognitive function. Additionally, ALCAR can help to protect the brain from damage caused by oxidative stress, and may even promote the growth of new brain cells.

In terms of athletic performance, Acetyl L-Carnitine is a belief to enhance the body’s ability to burn fat for energy, several studies illustrate this. By increasing the use of fat as fuel, athletes may be able to improve their endurance and overall stamina. Additionally, ALCAR may help to reduce fatigue and post-exercise soreness, allowing athletes to recover more quickly from intense workouts.

Acetyl L-Carnitine vs. L-Carnitine

Both Acetyl L-Carnitine and L-Carnitine are amino acids common in the human body. While Acetyl L-Carnitine is produced naturally in the body, L-Carnitine can also be obtained from food sources such as red meat and dairy.

L-Carnitine is a popular supplement in use in sports and weight loss supplements due to its ability to break down fat cells and convert them into energy. However, one of the drawbacks of L-Carnitine is that it’s not readily absorbable by the body. This is where Acetyl L-Carnitine comes into play. It’s a modified version of L-Carnitine that is better absorbable by the body, making it a popular choice for boosting energy levels.

Benefits of Acetyl L-Carnitine

May Boost Energy Levels

It can help boost your energy levels by preventing fatigue and enhancing mitochondrial function. Mitochondria are the energy-producing powerhouses in our cells, and ALCAR helps to fuel these powerhouses more efficiently, resulting in greater energy levels. This compound can also help improve exercise performance by increasing your body’s ability to burn fat for fuel, allowing you to work out for longer periods of time.

May Improve Cognitive Function

It is also known to be a nootropic supplement. What this means is that it can enhance cognitive function, including memory and attention span. ALCAR can also help improve brain function by increasing blood flow to the brain and by supporting the production of neurotransmitters, which are important for mood and cognitive well-being. By improving these functions, ALCAR can potentially help individuals in their daily tasks and further improve neurological health. It can also reduce age-related memory loss and improve your cognitive capabilities.

May Combat Depression and Anxiety:

It can serve as a natural remedy for depression and anxiety. ALCAR improves the levels of dopamine and serotonin, two neurotransmitters associated with positivity and good mood. It can also help alleviate depression symptoms such as fatigue, social withdrawal, and feelings of guilt.

May Improve Athletic Performance

It can also benefit athletes as it aids in energy production by enhancing the function of mitochondria. It helps to transfer fatty acids into the mitochondria where they convert into energy, providing an endurance boost during exercise. Moreover, long-term use of Acetyl L-Carnitine is associated with the increase in muscle mass and the reduction of muscle damage after exercise.

May Aid in Weight Loss

It can also aid in weight loss by supporting the body’s ability to burn fat. It works by transporting fatty acids into the mitochondria, where they can convert into energy that the body can use. This means that ALCAR can help increase the rate at which the body burns fat, resulting in a leaner physique over time. Its ability to improve energy levels can also make physical activity and workouts more accessible, further supporting weight loss efforts.

May Improve Insulin Sensitivity

Insulin resistance is one of the primary drivers of diabetes. One of the benefits of ALCAR is that it helps improve insulin sensitivity, meaning that your body can more effectively utilize insulin and properly manage glucose levels. This is crucial for type 2 diabetics, who often struggle with insulin resistance. ALCAR shows to improve insulin sensitivity by increasing the transport of glucose to cells and improving the activity of insulin receptors.

May Reduce Oxidative Stress

Oxidative stress is a major contributor to diabetes-related complications such as neuropathy, retinopathy, and nephropathy. ALCAR is a potent antioxidant that can help neutralize the free radicals that cause oxidative damage. In fact, several studies show that ALCAR can reduce oxidative stress in diabetics and improve their overall health.

Anti-Aging Benefits

It has powerful antioxidant properties that help to protect cells from damage caused by free radicals. This can lead to a reduction in the signs of aging, such as wrinkles, fine lines, and age spots. In addition, Acetyl L-Carnitine show to improve the health of mitochondria, which are responsible for energy production in the body. Improving mitochondrial health can lead to improved overall health and longevity.

Supports Heart Health

Another benefit of ALCAR is its ability to support heart health. This supplement can help improve blood flow, prevent damage to the heart, and reduce the risk of heart disease. ALCAR shows to decrease inflammation, which is famous to be a significant contributor to heart disease. Taking ALCAR regularly as a supplemental means could potentially help to improve overall heart health over time.

Side Effects of Acetyl L-Carnitine

Digestive Issues

One of the side effects of Acetyl L-Carnitine is digestive issues. Some people have reported feelings of nausea, diarrhea, and upset stomach when taking this supplement. If you experience these symptoms, you may need to halt the use of this supplement. It’s a recommendation that you consult a doctor if the symptoms persist or worsen, or if you develop more severe digestive issues.

Acetyl-L-Carnitine may lower blood sugar levels, making it a concern for individuals with diabetes as they could experience low blood sugar levels. The supplement may also negatively interact with blood sugar-lowering medication, exacerbating the drop in blood sugar levels.

Increased Thyroid Hormone Levels

Some studies report that Acetyl L-Carnitine may increase thyroid hormone levels. While this may seem like a positive effect, it may lead to hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone. Individuals with a history of thyroid issues should monitor their thyroid hormone levels when taking Acetyl L-Carnitine.

Increased Agitation and Anxiety Levels

Acetyl L-Carnitine may cause increased agitation and anxiety levels in some individuals. This effect may result from the supplement’s stimulating effect on the central nervous system. If you’re prone to anxiety or have a history of panic attacks, you may want to steer clear of Acetyl L-Carnitine.

Blood Pressure

Acetyl L-Carnitine can also impact blood pressure levels. Those with hypertension or high blood pressure should consult with their doctor before taking this supplement, as it may lead to a sudden drop or increase in blood pressure. If you’re already on medication for hypertension, taking Acetyl L-Carnitine may also interfere with its effectiveness.
