) is a naturally
occurring form of L-Carnitine, a vitamin-like
nutrient synthesized in the body from the amino

Acetyl-L-Carnitine
(
ALC
) is a naturally occurring form of L-Carnitine, a vitamin-like nutrient synthesized in the body from the amino acids lysine and methionine.
ALC
serves as a transport molecule for “active acetate,” which is a source of fuel for metabolic processes that take place in cells.
ALC
carries active acetate (the “Acetyl” portion) directly into the mitochondrion, the cell’s energy-generating structure. Active acetate is used to produce cellular energy in the form of ATP. Both L-Carnitine and
ALC
serve as fat carriers. Unlike L-Carnitine,
ALC
readily crosses the blood-brain barrier, where it has specific benefits for brain neurons. When taken orally,
ALC
has been shown to promote healthy
ALC
levels in both blood and cerebrospinal fluid, demonstrating its uptake in the brain.

Supports Cognitive Function*


ALC
has been studied for its effect on cognitive performance and emotional health in the elderly. In a single-blind, placebo-controlled trial, 481 elderly subjects taking 1500 mg of
ALC
per day were found to have improved scores on a memory test assessing cognitive abilities after 90 days of
ALC
supplementation.
2
In addition to being known for its effects on recognition and memory, placebo-controlled
ALC
research has also shown better scores in scales measuring the mood of elderly people.

Benefits
Supports Biosynthesis of Acetylcholine, a Key Neurotransmitter for Brain and Nerve Function*


Brain function requires coordinated communication between brain cells. Neurons (brain & nerve cells) communicate across tiny cell-to-cell gaps called synapses. The passage of an electrical impulse from one neuron to the next requires a neurotransmitter to act as a messenger to pass signals to adjacent neurons. When an electrical signal arrives at the synaptic junction, the neuron releases a neurotransmitter into the synapse. The neuron on the other side of the synapse contains receptors for the neurotransmitter (that will bind it), triggering a series of chemical events to send a new electrical signal down the membrane of the receiving neuron. Neurotransmitters work together like an orchestra to transmit information throughout the brain and nervous system.

Acetylcholine is the most abundant neurotransmitter in the body, regulating activities of vital organs and blood vessels, and communication between nerves and muscles. In the brain, acetylcholine helps to facilitate memory and learning, as well as influencing emotions.
ALC
is structurally similar to acetylcholine- enough so that brain neurons stimulated by acetylcholine are receptive to stimulation by
ALC
.
4
In an experimental animal model, it was shown that
ALC
can furnish acetyl groups to be utilized during the natural biosynthesis of acetylcholine.
5
ALC
’s structural similarity to acetylcholine has led researchers to investigate its effects on mental function and emotional health.
6
Helps Supply the Brain With Energy Through Mitochondrial Efficiency*


The acetyl groups donated by
ALC
can be used to naturally synthesize acetyl-CoA, the key substrate for energy metabolism in the mitochondrion.
1
Acetyl-CoA enters the Krebs cycle, the mitochondrial pathway that generates cellular energy in the form of ATP. Age-related decreases in mitochondrial oxidative capacity are a well-known cause of aging, as the organelles and organs in the body begin to operate less efficiently without ideal ATP production. The effects of decreased mitochondrial oxidative capacity are especially prevalent in organs that require high-energy inputs, such as the brain and heart. Recent clinical studies have shown that
ALC
helps to promote and maintain healthy mitochondrial function.
7
Helps Uphold the Integrity of Intracellular Membranes*


Phospholipids are structural components of brain cell membranes that regulate neuronal function.
ALC
has been shown to promote healthy membrane phospholipid metabolism in research subjects.
8
Additionally, the acetyl groups in
ALC
are naturally utilized by the body to modify the activity of proteins in neuronal membranes.
1
Through these means,
ALC
promotes normal membrane function, stability, and structural integrity.
9
Supports Nerve Growth Factor Production*


The body produces specialized proteins called growth factors that are essential to the growth and repair of tissue. Nerve Growth Factor (NGF) prolongs the survival of neurons in both the central and peripheral nervous systems. As we age, our central nervous system experiences a decrease in the binding of NGF to neuron membranes.
ALC
has shown the ability to promote the maintenance of normal interactions between NGF and neuron membranes.
10


Given to aged rats,
ALC
demonstrated effectiveness in promoting normal levels of NGF, and it helped maintain utilization of the growth factor in the rats throughout the duration of the study. Maintaining ideal levels of NGF is essential for the health of cholinergic neurons (nerve cells stimulated by acetylcholine), as cholinergic neurons lose some functional capacity due to a lack of NGF. In aged rats,
ALC
is known to promote the health of cholinergic neurons.
11
In sum, such results suggest that
ALC
positively influences the maintenance of healthy and normal NGF activity.
1
Supports Healthy Brain Neuron Function*


Several animal studies have revealed that
ALC
contains many biochemical characteristics that help neurons face the aging process optimally.
12, 13

ALC
has been shown to raise levels of glutathione, a key antioxidant, in isolated mouse brain tissue.
14
ALC
also reduces blood levels of MDA (malondialdehyde), a free radical byproduct.
15
Furthermore,
ALC
is a
chelator of iron: it acts as a molecule that can naturally sequester iron in the body to prevent iron-mediated oxidative damage to cells.
16
As a whole, data from in vitro and animal studies suggest that
ALC
is effective towards the maintenance of healthy brain neurons and normal neuronal energetic processes. This hypothesis is supported by human studies that demonstrate the potential of
ALC
to promote healthy brain function in elderly persons.
