What is Doctor’s Best Acetyl L-Carnitine?
Doctor’s Best Acetyl-L-Carnitine is a naturally occurring form of L-Carnitine which is a vitamin-like nutrient synthesized in the body from the amino acids lysine and methionine. It supports cognitive function and supports healthy brain neuron function. Acetyl-L-Carnitine plays a key role in the production of acetylcholine, an important neurotransmitter for brain and nerve cell function. Acetyl-L-Carnitine helps supply the brain with energy by increasing mitochondrial efficiency, supports nerve growth factor production and helps to uphold the integrity of intracellular membranes. Doctor’s Best Acetyl-L-Carnitine contains Biosint Acetyl-L-Carnitine, which is manufactured in Italy by the reputable company Sigma-Tau with a patented, FDA-approved process that fully complies with the USP 25, FCC 4 and EU monographs.
How does it work?
Acetyl-L-Carnitine serves as a transport molecule for “active acetate,” which is a source of fuel for metabolic processes that take place in cells. Acetyl-L-Carnitine 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. Unlike L-carnitine, Acetyl-L-Carnitine readily crosses the blood-brain barrier, where it has specific benefits for brain neurons.

Quality product. Acetyl-L-carnitine should be used to improve brain function, but not primarily for energy production and fat burning during strength training)

There are many options for finding acetyl L-carnitine, but who actually made the compound? I was using another brand that quietly dropped that they used Biosint. That means it was made in some who knows op

As expected, pleasant to swallow and without a weird aftertaste that is hard to deal with like some others. the packaging is plastic (why???), which could be improved with glass, like other companies are doing these days. at first i was really happy

Doctor’s Best uses premium Sigma Tau ALC, but tends to cost a little less than brands that do the same. I’ve been using it for over a decade with great noticeable results, although the results may not be as noticeable to everyone.
