So today we are exploring a supplement that I discovered and it has radically improved my health so I want to make sure you know about it.  Acetyl-L-Carnitine, ALCAR or ALC has many benefits and uses.  It is an acetylated form of carnitine. Carnitine and acetyl-L-carnitine are two very different supplements and you should know the difference between them before deciding to take one or both.

Acetyl-L-carnitine is a natural super antioxidant and is known to help both brain and body.  Rather than L-carnitine that doesn’t cross the blood brain barrier, acetyl -L-carnitine does and therefore has positive impact on the brain.  The naturally-occurring, chemical compound carnitine, or L-carnitine, is technically speaking, not an amino acid. It is actually a dipeptide made from the essential amino acids lysine and methionine. It is therefore often classed as a conditionally essential amino acid. ALC may also provide substrate (acetyl groups) for synthesis of acetylcholine—a primary neurotransmitter in the brain.

Acetyl-L-carnitine is a potent antioxidant and neuroprotectant known for its powerful nootropic properties.  Nootropics are compounds that benefit brain function. ALCAR also enhances energy and alleviates the effects of aging. It improves focus, cognition and mental clarity.  It is increasing the energy in the brain.

ALCAR is a potent antioxidant that flushes out the toxins and damaged fats in your brain. It is therefore preventative against neuro-degenerative conditions such as Parkinson’s and Alzheimer’s.

Fatty acid mobilization into the mitochondria

Carnitine’s primary job is to transport fatty acids into the mitochondria.  Acetyl-L-Carnitine does increase mitochondrial energy production and powers up energy-starved brain cells.

Brain function and memory

Research has shown that ALCAR improves memory in older people. It can also slow down the progression of Alzheimer’s disease. The acetyl group in ALCAR can be used to form acetylcholine.  Acetylcholine is an important neurotransmitter that dramatically declines as dementia advances. It’s a useful supplement for neurological conditions such as Parkinson’s, stroke victims, and individuals born with Down Syndrome. This is a super important benefit of ALCAR. Imagine slowing down all the mental decline in the US?  You could be saving millions of people from dementia.

Acetyl-L-carnitine and diabetes

Acetyl-L-carnitine can assist with nerve damage associated with diabetes.

Fibromyalgia and acetyl-L-carnitine

A randomized controlled trial comparing duloxetine and acetyl L-carnitine in fibromyalgic patients showed that while both duloxetine and acetyl-L-carnitine had positive effects, the acetyl-L-carnitine also improved depression and overall quality of life.

Acetyl-L-carnitine and hyperthyroidism

This is how I came across the wonders of acetyl-L-carnitine.  As a Grave’s sufferer, I experience hyperthyroidism.  My body runs way too fast burning up everything in it’s pathway.   This may sound awesome in that it keeps off the weight but it also burns up my cells and causing faster degeneration or aging.  Who wants that?  Not me. I don’t absorb my nutrients as I should.  Even though I supplement many different vitamins and minerals, my body can’t absorb the nutrients.

I supplement 1000mg of acetyl-L-carnitine a day along with 2500 mg of carnitine.  It has increased my energy, my focus, stamina and allowed me to build muscle while shedding fat.  You can imagine I am super happy with the results.

Acetyl-L-carnitine and athletes

There is research to show that ALCAR increases stamina, endurance and overall energy in athletes.  Athletes today are taking ALCAR as well as carnitine before and after their workouts.

Acetyl-L-carnitine and weight loss

Intake of ALCAR is a great way to lose weight by maximizing muscle and releasing fat, but to maximize results research has shown that when taken with omega-3 fatty acids, fat loss and burning will dramatically improve. With the ability to increase protein synthesis, acetyl-L-carnitine is excellent both for fat loss and muscle gain.

Should you supplement Acetyl-L-carnitine?

Determining whether to supplement Acetyl-L-carnitine, you want to find a suitable functional medicine test.  There is a great test that will show your need for carnitine.  It is the Comprehensive Organix Acids Test from Genova Diagnostics.  You can order it from our clinic or get it online and find a qualified practitioner to analyze it for you. While the lab gives you a summary, there is so much information in this test, it takes a qualified person to analyze it for you.  You will learn much about your health from these metabolite readings.  And more importantly, you will learn how to correct your nutritional imbalances with a nutrition program.

Now that you have decided to take Acetyl-L-carnitine, you can get yours here at our store or book a free consultation to discover how we can help you on your health journey.
