Carlson Laboratories Acetyl L-Carnitine Powder is a nutritional supplement designed to support memory and concentration. Carlson Labs is the manufacturer of the formula, which makes it available in both powder and capsules forms. The manufacturer argues that the benefits of free form amino acids such as Acetyl L-Carnitine far exceed those of supplementation with proteins directly.

Carlson Laboratories was founded in 1965 and activated in the nutritional health supplement sector. The company product range has expanded through the years to meet the nutritional needs of the customers. Today, the product lines include award-winning Norwegian fish oils, a full line of vitamins (including the most complete line of natural vitamin E products in the world), minerals, amino acids, special formulations and nutritional supplements.

Carlson Laboratories Acetyl L-Carnitine Powder is for adult use only, except pregnant or lactating women.

Carlson Laboratories Acetyl L-Carnitine Powder Ingredients

Carlson Laboratories Acetyl L-Carnitine Powder contains the following ingredients: Acetyl-L-Carnitine (as acetyl-l-carnitine HCl).

Product Features

Carlson Laboratories Acetyl L-Carnitine Powder is a single ingredient amino-acid based supplement. The formula is advertised to be soy, milk, wheat, corn, yeast, gluten, sugar, salt and preservative free.

Acetyl L-Carnitine is an amino acid. It is one of several forms of Carnitine found in the body, compounds naturally produced and regulated by the kidneys. One of the main functions of Acetyl-L-Carnitine is to transport fatty acids to the mitochondria (known as the power plant of the cell) thus facilitating fat to be used as fuel in the energy production processes.

The brain protective action of Acetyl L-Carnitine is accounted for by the fact that all Carnitines are antioxidants, meaning they counteract the damaging effects of free radicals. Additionally, the acetyl group attached to L-Carnitine is involved in the production of the key neurotransmitter Acetylcholine, essential to learning and memory processes. Research is now conducted to determine if Acetyl-L-Carnitine can assist with disorders such as depression, ADHD and Alzheimer’s disease.

The suggested dose is half a teaspoon dissolved in water. No side effects are mentioned although stomach upset, nausea, vomiting, restlessness and a “fishy” odor of the urine, breath and sweat have sometimes been reported.

  • Powder form makes it easy to dissolve and administer;
  • Soy, milk, wheat, corn, yeast, gluten, sugar, salt and preservative free;
  • The formula is available in glass bottles to minimize the hydroscopic effects.


  • Lack of consumer reviews;
  • No side effects, drug interactions or precautions are mentioned by the manufacturer, although Acetyl-L-Carnitine is known to cause side effects;
  • Not suitable for pregnant and nursing women.


Carlson Laboratories Acetyl L-Carnitine Powder is a source of Acetyl L-Carnitine, an important amino acid with multiple health benefits. Although many of these benefit claims are still under research and clear evidence is still required. Regarding the formulas specific memory and concentration enhancement benefit claims, there is some evidence to support the fact that Acetyl L-Carnitine has neuro protective and cognitive enhancing properties. While we could not find any product reviews, we may say the product is likely to work for some consumers.

The manufacturer doesn’t mention any interactions with other medicine or categories of patients who should avoid use, although clinical tests on Acetyl-L-Carnitine have indentified potential side effects. Pregnant and nursing women are advised not use the formula.
