What’s L-Carnitine Base?

L-Carnitine Base is base form of carnitine. The compounds L-carnitine tartrate, acetyl L-carnitine, and fumarate L-carnitine are derived from this product. An amino acid derivative plays a vital role in several metabolic processes, including metabolism and energy production. It is found in several food sources, including dairy and meat products, and is a quaternary ammonium compound. L-carnitine is a powerful weight-loss ingredient and an essential compound for optimum brain function.

The compound is featured as having CAS number 541-15-1, the molecular formula of C7H15NO3, and a molecular weight of 161.2 g/mol. It is also known by names: (R)-3-Carboxy-2-hydroxy-N, N, N-trimethyl-1-propanaminium, Inner Salt, and L-Carnitine.

L-carnitine has a white, crystalline, hygroscopic powder appearance and is easily soluble in water, lye, methanol, and ethanol. Nutriavenue offers the product in 1-kilogram retail packaging or 25-kilogram net weight packaging for bulk purchases.

What Is The Difference Between L-Carnitine And L-Carnitine Base?

The terms L-carnitine and L-Carnitine Base are almost used interchangeably in the dietary supplement field. Thus, there are no significant differences between the two compounds regarding identifiers, functions, and health benefits.

Common L-Carnitine Base Powder Specifications

L-Carnitine Base powder 99% is an L-Carnitine Base form available in the market.

We usually pack the product in paper drums with two layers of polybags inside when bought in bulk or in paper bags in retail. We also offer shipping services to customers upon request.

What Is Carnitine Base Powder Manufacturing Process?

In the production of L-Carnitine Base, (S)-3-activated hydroxy butyrolactone is used as raw material. The production process starts by subjecting the raw material to a ring-opening reaction in the aqueous solvent to obtain 4hydroxy-3-activated hydroxybutyric acid. After that, the resultant compound is subjected to an inverse conversion reaction at the chiral center with a base to prepare the salt of 3,4-epoxy butyric acid. Again, 3,4-epoxy butyric acid undergoes nucleophilic substitution with trimethylamine to produce L-carnitine.

What Types Does Carnitine Have?

Several types of carnitine occur naturally and are found in the market. These include the following:

  • D-Carnitine

D-Carnitine powder is the optical isomer of the well-known form L-Carnitine. It is known to inhibit the absorption of other forms of carnitine in the human body. Thus, it is not recommended for human consumption.

  • L-Carnitine Tartrate

L-Carnitine Tartrate powder is the form of carnitine that is commonly used in dietary supplements for athletes. It is believed to increase fatty acid oxidation, reduce purine catabolism, and free radical formation.

  • Acetyl-L-Carnitine (ALCAR)

Acetyl-L-Carnitine ALCAR powder is a well-known form of carnitine as it provides neuroprotective properties aside from enhancing metabolism. Thus, it may improve cognitive functions.

  • Propionyl-L-Carnitine

Propionyl-L-Carnitine powder is the form that provides other benefits such as improving cardiac health, relieving pain, and reducing rheumatic symptoms.

The best form of carnitine for dietary supplement products depends on the target users and the intended added benefits.

L-Carnitine Base vs. L-Carnitine Tartrate

L-carnitine tartrat C18H36N2O12


L-carnitine tartrate is usually found in pre-workout supplements as it reduces muscle soreness and speeds up recovery during workouts. Its molecular formula is C18H36N2O12, and its molecular weight is 472.5 g/mol.

According to research, L-carnitine tartrate is absorbed faster than L-carnitine base and other forms of carnitine. Hence, it is ideal for use when time is a critical consideration, such as before the performance of workouts. For this reason, L-carnitine tartrate may be better than L-carnitine base.

Acetyl L-Carnitine vs. L-Carnitine

More popularly known as ALCAE, Acetyl-L-Carnitine is the form of carnitine that can cross the blood-brain barrier and produce cognitive benefits. It is identified as having CAS number 3040-38-8, molecular formula of C9H17NO4, and a molecular weight of 203.24 g/mol.

While both ALCAR and L-carnitine are shown to enhance cognitive benefits, it was found that the former is more readily absorbed in the gut and can cross the blood-brain barrier better than the latter. Thus, for cognitive health and increased brain energy, ALCAR is better than L-carnitine.

How Does L-Carnitine Base Work?

L-Carnitine Base primarily works by increasing energy levels in the human body. Studies show that it does so by transporting the chains of fatty acids into the mitochondrial matrix. It effectively allows the cells to break down fat and get energy from the stored fat reserves. This mechanism results in effective weight loss among individual users and an increased sense of well-being.

Another study also found that the compound may help reduce cognitive decline by restoring cell membranes and synaptic functioning and promoting mitochondrial energy metabolism. It is also claimed to exert neurotrophic effects.
