ALCAR Powder is a powdered Acetyl L-Carnitine supplement which provides antioxidant benefits and more. It’s sold by Live Long Nutrition (LLN), a company from Westminster, South Carolina. The company was founded in 2007 to specialize in single ingredient supplements for increasing physical and mental capabilities. They say this nootropic product can improve your memory, increase neurotransmitters, and more. Anyone looking to improve their mind, or get help in their fitness routines, could potentially benefit from buying ALCAR Powder. LLN prides themselves on offering a range of supplement options to athletes and other people.


1) What is ALCAR Powder?

Each jar of ALCAR Powder contains 100 one-gram scoops of Acetyl L-Carnitine (ALCAR). ALCAR is a nootropic substance involved with energy, metabolism, and the mitochondria in general. It’s found in the human body and some foods. It goes well with some antioxidants like Alpha Lipoic Acid, plus choline and caffeine. It’s thought to be an effective fat burner, but doesn’t do anything on its own unless you have an L-Carnitine deficiency. ALCAR can help you lose weight, through giving you more energy, but generally the weight loss only comes from proper diet and exercise. It has a stimulant effect, but isn’t a stimulant itself, and doesn’t have any of their potential adverse effects. There are other forms of L-Carnitine, and this one is primarily for cognitive enhancement and energy increases.

2) Ingredients of ALCAR Powder

ALCAR Powder contains the following ingredients: Acetyl L-Carnitine (1 g).

3) Does ALCAR Powder Work?

Each jar of ALCAR Powder contains 100 one-gram scoops of Acetyl L-Carnitine (ALCAR). A standard dose is considered to be within the range of 0.6 g (630 mg) and 2.5 g (2,500 mg). This means you can take more or less of the powder depending on your personal needs, and it’ll be completely safe. ALCAR is an amino acid naturally produced in your body to boost energy. It’s popular in supplements as well, because it has some antioxidant properties.

Clinically, it’s used for a lot of reasons: boosting virility, combating memory loss due to Alzheimer’s or age, fending off depression, improving poor circulation in the brain, reducing nerve pain, and assisting with thinking problems related to alcohol or Lyme disease. More evidence needs to be acquired to verify its uses related to depression and Lyme. It’s considered safe for use, although the following people should avoid Acetyl-L-Carnitine until more research is done: pregnant or breastfeeding women, people with underactive thyroids, or people prone to seizures. Side effects are rare but can include nausea, vomiting, and restlessness. It may also cause your breath or urine to have a “fishy” odor.

Health Benefits

4) ALCAR Powder Health Benefits

  • Not a stimulant, but stimulant-like effects can occur. This may be a disadvantage for some people.
  • Inexpensive supplement which can last for three months or longer.

5) ALCAR Powder Warnings and Precautions

  • Not a disadvantage for many people, but this is a one-ingredient product. Some people could be better served with an effective powder or capsule formula.
  • Could get a little expensive if you use the maximum standard dose (2.5 g daily) instead of Live Long Nutrition’s recommended dose (1 g daily). However, the price would still be reasonable enough (average instead of below average price).

6) How Much Does ALCAR Powder Cost?

Each jar lasts for about one hundred days, so this product is generally a good deal regardless of where you purchase it. It’s available for sale at a number of places, including the company website and Amazon. The price can vary depending on your point of purchase. But in all cases, the price doesn’t vary too significantly, and the price is always reasonable. This is a long lasting supplement even if you use it daily. Live Long Nutrition products can reportedly be purchased in the United States, Mexico, Europe, Australia, Canada, and Russia.


7) Directions For Taking ALCAR Powder

Effects include decreasing ammonia levels, increasing sperm quality, decreasing blood glucose levels, decreasing oxidation, and reducing muscle damage. It can lower fatigue and increase cognitive performance in some people, but might be best as a potential treatment for Hepatic Encephalopathy. (It may decrease fatigue and fat levels in the elderly. The evidence is mixed for younger people.)

Final Thoughts

8) Final Thoughts on ALCAR Powder

ALCAR Powder is marketed as being able to enhance metabolism, increase focus, and supplant recovery after working out. It does have a lot of potential benefits, and will best serve people who are extra serious about fitness. A relatively sedentary person shouldn’t expect to see many gains (or losses, depending on your outlook) from taking ALCAR. It gives a physical and mental boost that you can use to your advantage to obtain certain types of goals. This product also works well as part of a nootropic stack. Being one ingredient, it’s easy to mix and match with other ingredients. If you need an ALCAR supplement, this might be one of the best products on the market for you.
