Product Description
Doctor's Best - Acetyl L-Carnitine with BIOSINT 500mg VegeCaps 60
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 plays a key role in the production of acetylcholine, an important neurotransmitter for brain and nerve cell function.
Benefits
-
Supports cognitive function, improved memory and mental alertness
-
Key role in production of Acetylcholine (key neurotransmitter for brain and nerve function)
-
Support for energy metabolism in the brain
-
Supports healthy membrane structure in brain cells
-
Support for senile dementia, Alzheimers, depression
-
Helps decrease free radical production in the brain
-
Helps keep nerves healthy and in repair
-
How does Acetyl-L-Carnitine work?
-
ALC works in a similar way to L-Carnitine (both are fat carriers), but ALC carries the ‘Acetyl’ portion directly to the mitochondria (powerhouse of the cell) to produce ATP. ALC also crosses the blood –brain barrier (L-Carnitine does not) where it has specific benefits for brain neurons.
Supports cognitive function
ALC is structurally similar to acetylcholine - the most abundant neurotransmitter in the brain – important for brain and nerve cell function. Research has shown that brain neurons stimulated by acetylcholine are receptive to stimulation by ALC.

Supports brain energy
The acetyl groups donated by ALC are used to produce energy in the cell. This is of particular benefit for organs that require high-energy inputs, such as the brain and heart. Many studies have shown that ALC helps to support healthy mitochondrial function and promote healthy membrane structure in neuronal membranes.

Supports nerve growth factor
The body produces specialized proteins called growth factors that are essential to growth and repair of tissue. Nerve Growth Factor (NGF) prolongs the survival of neurons in the central and peripheral nervous systems.

Ageing
Studies have shown that ALC may help brain neurons face the ageing process optimally by decreasing free radical production in the brain.
