Description

Acetyl L-Carnitine (ALCAR) is an acetylated form of L-Carnitine which is similar to typical L-Carnitine but is able to cross the blood-brain barrier. L-Carnitine is a compound naturally produced by the body which plays a key role in the mitochondrial oxidation of long-chain fatty acids.

When taken as a supplement, ALCAR supports exercise endurance and stamina, particularly for resistance training. Since ALCAR can cross the blood brain barrier, unlike the non-acetylated L-Carnitine it supports cognitive function and attention.

Recommended Dosage

As a supplement for exercise endurance or cognitive support, take 2-4 capsules (1000 mg – 2000 mg) per day on an empty stomach. It’s not recommended to take over 6 capsules (3000 mg) per day due to increased risk of side effects.

Frequently Asked Questions About Acetyl-L-Carnitine

What is Acetyl-L-Carnitine?

There is an amino acid found in most of the cells in your body and made by the liver and kidneys, called L-Carnitine, which helps the body produce energy. Animals produce this amino acid, too – which means you can consume it in some foods.

L-Carnitine is found in meats and fish, which is part of the reason for its name. The Latin word for “flesh” is “carnus.” The L-Carnitine consumed in foods helps supplement natural levels in the body. Vegans and people with particular genetic diseases are sometimes unable to produce enough L-Carnitine, so it is considered a conditionally essential nutrient.

Acetyl-L-Carnitine, otherwise known as ALCAR, is a form of L-Carnitine with a compound attached to it, called an acetyl group. It’s an amino acid derivative. The acetyl group that’s attached to the amino acid helps contribute to the production of a neurotransmitter called acetylcholine.

Neurotransmitters are often called the body’s chemical messengers because they help transmit messages between nerve cells. Acetylcholine, in particular, helps transmit messages between motor neurons, which control muscle contractions, and is required for mental function. It is found in the brain and throughout the nervous system. In the body, L-Carnitine is naturally converted into Acetyl-L-Carnitine.

Acetyl-L-Carnitine is available as a supplement and has been studied for its potential mental health and cognitive decline applications. Aging appears to correlate with L-Carnitine deficiency, and Acetyl-L-Carnitine supplements can help counter the deficiency, according to Examine.

There is pretty good evidence that Acetyl-L-Carnitine supplements can help delay age-related cognitive decline, and reduce symptoms of diabetic neuropathy, according to the University of Michigan. Some research shows Acetyl-L-Carnitine may help with conditions such as Alzheimer’s disease, depression, erectile dysfunction, and fibromyalgia, according to the university.

What Are the Benefits of Acetyl-L-Carnitine?

There are a number of uses identified for Acetyl-L-Carnitine, with most related to supporting cognitive functions. Some of these uses include:

  • Age-related cognitive decline: Acetyl-L-Carnitine supplements may help slow cognitive decline related to age, or help improve cognitive functions of the senile brain, according to research. One study found that short-term, intensive treatment with Acetyl-L-Carnitine supplements can improve the mental function of the senile brain without side effects. Another study found that supplementing with Acetyl-L-Carnitine can help with general cognition in the elderly.
  • Alzheimer’s disease: Alzheimer’s disease is a progressive, age-related condition that destroys important mental functions and memory. Some short-term studies show that Acetyl-L-Carnitine supplements can slow the progression of the disease, improve memory and enhance mental performance, according to the University of Michigan. One study has shown that Acetyl-L-Carnitine supplements may have a beneficial effect on short-term memory, while another study found it may slow overall deterioration in some cognitive areas. More research is needed.
  • Depression: One recent study showed the Acetyl-L-Carnitine can have the same effects as an antidepressant medication called fluoxetine on elderly patients with depression. Fluoxetine is a serotonin reuptake inhibitor, but the study suggests that Acetyl-L-Carnitine works through different mechanisms due to a difference in latency time of clinical response.
  • Erectile dysfunction: Erectile dysfunction is a very common condition that affects a man’s ability to have sex. Acetyl-L-Carnitine supplements may help with this condition. One study found that Acetyl-L-Carnitine combined with Propionyl-L-Carnitine safely and reliably improved sexual potency in men who had a particular surgical procedure that resulted in erectile dysfunction. More research is needed, however.
  • Diabetic neuropathy: Diabetic neuropathy is nerve damage that results from diabetes, and most often affects the legs and feet. One study concluded that Acetyl-L-Carnitine treatments are effective in alleviating symptoms, such as pain, and improves healing – specifically nerve fiber regeneration.

How Do I Take Acetyl-L-Carnitine?

Dosages of Acetyl-L-Carnitine range between 630 and 2,500mg, according to Examine. It is taken daily by mouth. No official dosage recommendation exists.

It’s best to follow manufacturer instructions and speak with your doctor for guidelines.

How Do I Pick a Good Acetyl-L-Carnitine Product?
