Acetyl-L-carnitine ALCARthe short-chain ester of carnitine, is a common dietary supplement readily available in health food stores, claimed to improve energy levels and muscle strength. ALCAR has numerous effects on brain and What is alcar metabolism, protects against neurotoxic insults and may be an effective treatment for certain forms of depression. However, little is known about the effect of chronic ALCAR supplementation on the brain metabolism of healthy mice. Here, we investigated ALCAR's effect on cerebral energy and neurotransmitter metabolism after supplementing the drinking water of mice with ALCAR for 25 days, providing a daily dose of about 0. Thereafter the animals were injected with [1- 13 C]glucose, and 13 C incorporation into and levels of various metabolites were quantified in extracts of the hippocampal formation HF and cortex using 1 H- and 13 C-nuclear magnetic resonance NMR spectroscopy and high performance liquid chromatography HPLC. Increased glucose levels were detected in both regions together with a decreased amount of [3- 13 C]lactate, but no alterations in incorporation of 13 C derived from [1- 13 C]glucose into the amino acids glutamate, GABA and glutamine.

ALCAR is unique because it is able to cross the blood-brain barrier more easily than L-carnitine, making it more effective for enhancing cognitive function.

Research has found ALCAR to be capable of reducing the symptoms of mild cognitive impairment by improving memory, attention, mood and other cognitive functions. Amazingly, the positive cognitive effects seem to persist even after stopping short-term supplementation.

ALCAR can also increase L-carnitine levels in those who are deficient due to factors such as the use of certain medications, disease, a strict vegetarian diet, and heart or circulatory conditions. Some people use L-carnitine for athletic performance and endurance as it promotes energy production and proper fat burning.

Muscle fatigue, male infertility due to poor sperm healthRett syndrome, chronic fatigue syndrome, anorexia, attention deficit-hyperactivity disorder ADHDthyroid imbalances, leg ulcers, high cholesterol and Lyme disease are all common conditions that may benefit from ALCAR supplementation.

ALCAR is beneficial for people of all walks of life including the young, middle-aged and elderly, vegetarians, infertility patients, brain rehab patients, those experiencing chronic fatigue and athletes. Since the benefits remain after one stops taking it, it is a worthwhile investment with good returns for anyone looking for additional memory, metabolic and general health support.

This particular ester also has numerous cognitive benefits associated with it that are not attributed to regular L-carnitine. ALCAR readily crosses the blood-brain barrier and helps to reduce fatigue, support cognitive function in the elderly, maintain cognitive function during aging and even relieve pain associated with diabetic neuropathy.

Capsule: hypromellose. Cognitive Health: Study 1: Based on preliminary evidence from a multi-centered, double-blind, placebo-controlled study evaluating What is alcar effects of ALCAR on the cognitive deficits of alcoholics on at least one month of abstinence, researchers wanted to evaluate the effect of ALCAR supplementation in patients showing impaired performance in cognitive tasks.

Participants were assessed on neuropsychological battery exploring the areas of memory, constructional praxia, deductive-logical functions, and language, at time zero, after 45 days and after 90 days of supplementation.

The show a ificant difference between the placebo group and ALCAR supplementation after 90 days in the memory and intelligence tests carried out. These suggest that ALCAR supplementation has health benefits on cognitive function in chronic alcoholics. There are some options to assist with the symptoms of AD, as well as try to improve the quality of life of patients and caregivers.

This randomized, double-blind, placebo-controlled, parallel-group study aimed to compare ALCAR and a placebo treatment in patients with dementia caused by AD. Participants were given either a placebo control medication or ALCAR 1 g twice daily for 24 weeks, with assessments going on during the study. Additionally, a positive trend in reaction time in the computerized classification test was observed in the ALCAR group, suggesting less cognitive deterioration, compared to the placebo group. Study 3: This study aimed to What is alcar the distinct effects of acetyl- and propionyl-carnitine, alone and in combination in patients with mental fatigue and chronic fatigue syndrome in this open, randomized clinical trial.

Supplementation went on for 24 weeks and participants were monitored by the clinical global impression of change, multidimensional fatigue inventory, McGill pain questionnaire, and the Strrop attention concentration test. Each test was administered eight weeks before treatment commenced, at baseline and then after eight, 16, and 24 weeks of treatment and two weeks after treatment. The show that ALCAR and PLCAR individually improved symptoms of mental fatigue, attention, and concentration; however, the combination group appeared to do ificantly worse than the individual treatment groups.

The main critique of this study is a lack of positive or placebo control groups, which could be compared to the effect of each treatment group.

What are the benefits of acetyl-l-carnitine?

Another study, published later, just looked at the effect of ALCAR in elderly patients with fatigue, where they show that supplementation with ALCAR was associated with a reduction in both physical and mental fatigue while improving both cognitive status and physical functions.

Non-diabetic subjects at an increased risk for cardiovascular diseases were recruited for this study and were supplemented with 1g ALCAR twice daily for 24 weeks. Patients were assessed for glucose disposal rate GDR and blood pressure markers at intervals during the study. Lower GDR was also associated with improved glucose tolerance, suggesting that ALCAR supplementation can help reduce arterial hypertension, improve insulin resistance, impaired glucose tolerance, and hypoadiponectinemia in subjects at increased cardiovascular risk. Study 2: This randomized, placebo-controlled, double-blinded study aimed to determine the effects of ALCAR supplementation on resting and postprandial biomarkers of glucose and lipid metabolism, as well as oxidative stress.

Pre-diabetic subjects were randomized to placebo or ALCAR 3 g per day supplementation group and fasting blood samples were taken from subjects both pre and post-intervention. After each fasting sample was obtained, subjects consumed a high fat, high carbohydrate meal, and additional blood samples were taken at one, two, four, and six hours post-meal.

Samples were analyzed for a variety of metabolic variables e. Study 3: The aim of this randomized controlled study was to explore the role of L-carnitine supplementation in influencing insulin sensitivity in patients with impaired fasting glucose or type II diabetes. Within 10 days of diagnosis, patients meeting the inclusion criteria were recruited for the study.

Patients were randomly ased to receive a hypocaloric diet for 10 days or the same dietetic regimen in addition to oral L-carnitine 2 g twice daily supplementation. showed that L-carnitine supplementation as associated with a reduction in plasma insulin levels and HOMA-IR, compared to the diet alone and baseline values. This suggests that L-carnitine supplementation, along with caloric restriction could improve insulin resistance in patients with impaired fasting glucose and type II diabetes.

Study 4: The effect of carnitine supplementation on non-oxidative glucose disposal has been established in several pre-clinical research models. ificant differences were observed between the placebo and supplementation groups on the following assessed endpoints: Although there was also a ificant difference in the responses of the lean What is alcar overweight participants, a ificant decrease in plasma glucose concentration in both groups, which was not dependent on the GLP Study 5: The aim of this study was to assess the effect of L-carnitine supplementation on plasma lipids and expression of enzymes involved in the regulation of fatty acid and glucose oxidation, as a way to determine the effect of this supplementation on insulin resistance.

The show a ificant decrease in free fatty acids and plasma triglycerides. This finding was important, as increased free fatty acids are hypothesized to be one of the main causes of insulin resistance and consequently gestational diabetes.

Study 6: In this analysis of two randomized, placebo-controlled clinical trials, the authors sought to evaluate the effect of two doses of long-term ALCAR supplementation in patients with clinical diabetic neuropathy. Patients received either a placebo, mg, or mg ALCAR three times a day for 52 weeks and they were assessed for sural nerve morphometry, nerve conduction velocities, cibration perception thresholds, clinical symptom scores and a visual analog scale VAS for pain.

The from both studies and the analysis showed ificant improvements in sural nerve fiber s and regenerating nerve fiber clusters, as well as vibration perception.

In this study giving mg ALCAR three times daily, a reduction in pain was also observed, demonstrating that ALCAR effectively reduces pain and improves nerve fiber regeneration and vibration perception in diabetic patients, suffering neuropathy. Cardiovascular Health: Study 1: The L-Carnitine Ecocardiografia Digitalizzata Infarto Miocardico CEDIM clinical trial was a double-blind, randomized, placebo-controlled, multicenter study that evaluated the effects of L-carnitine supplementation on long-term ventricular dilation in patients with acute anterior myocardial infarctions.

Left ventricular volumes and ejection fraction was evaluated on admission, at discharge from hospital and at three, six, and 12 months after acute myocardial infarction. A ificant reduction in left ventricular dilation in the first year after myocardial infarction was observed in the L-carnitine supplementation group, compared to the placebo. In addition, a ificant reduction in the high end-diastolic and systolic volumes was observed with supplementation, suggesting that L-carnitine supplementation could promote heart health and recovery after acute myocardial infarction.

Study 2: In this open, blind end-point, longitudinal, sequential off-on-off, prospective, pilot study, the effect of ALCAR supplementation on increased cardiovascular risk was observed. Non-diabetic subjects at an increased risk for cardiovascular diseases were recruited for this study and were supplemented with 1 g ALCAR twice daily for What is alcar weeks. Study 3: This systematic review and meta-analysis evaluated the effects of L-carnitine and ALCAR supplementation, in comparison with a control, on mortality and morbidity in the settings of acute myocardial infarctions.

This review included 13 controlled trials, with a participant population of and the following endpoints were included in the analysis: mortality, ventricular arrhythmias VAsangina, heart failure, and reinfarction. This molecule is critical for normal skeletal muscle bioenergetics, because of its dual role in fatty acid transport and oxidation and mitochondrial energy production; both processes are required for exercise performance and peak muscle effects.

Finally, this single-blind crossover study looked at the effect of L-carnitine supplementation on pain, tenderness, and cytokine release induced by exercise. Although these studies are looking at the effect of L-carnitine supplementation, it is not difficult to extrapolate this effect on other forms of carnitine, including the acetylated ALCAR.

This molecule is highly bioavailable, can cross the blood-brain barrier, and has the same effects on fatty acid transport and oxidation, as well as mitochondrial bioenergetics. These processes are essential for muscle health and energy production. Share Tweet Pin.
