Acetyl L-Carnitine



Advanced L-Carnitine


  • Improves Exercise Performance*
  • Facilitates Fat Metabolism*
  • Reduces Oxidative Stress*
  • Enhances Cognition*
  • Reduces Ammonia*
  • 60 Servings





The fats that we eat and our body naturally forms are broken down inside organelles called the mitochondria. Carnitine is an essential compound for transporting fatty acids across the mitochondrial membrane, and Acetyl L-Carnitine is unique as a carnitine source because it is able to cross the blood brain barrier and improve attention and cognition. Acetyl L-Carnitine has been shown to:


  • Increase fatty acid oxidation and decrease body weight*
  • Improve recovery from exercise and decrease soreness*
  • Reduce lipid peroxidation (an antioxidant effect)*
  • Decrease levels of ammonia and lactic acid.*
  • One study has also noted that L-Carnitine may enhance Androgen Receptor Density on muscle tissue in men.*


Any way you slice it, the body needs L-Carnitine. In its acetylated form, Acetyl L-Carnitine, chaperones fats to meet their maker while also improving cognition with its ability to cross the blood brain barrier, and acting as an antioxidant. Supplementing with L-Carnitine has been shown to provide numerous health benefits including loss of body fat, so it is a great addition to any supplement plan.

Ingredient Profile

Acetyl L-Carnitine

L-Carnitine is an amino-acid based compound that is essential for transporting long-chain fatty acids into the mitochondria where they are broken down for energy production. Acetyl L-Carnitine is more bioavailable and promotes healthy brain function.


  • Supplementation with L-Carnitine has been demonstrated to reduce muscle soreness and muscle damage after exercise.
  • A study conducted by Volek et al. (2002) found that supplementation with L-Carnitine daily for one week in healthy resistance trained men was able to reduce markers of muscle damage after weight lifting. It was also discovered that biomarkers of oxidative damage reduced to baseline sooner than placebo.
  • Consuming Carnitine prior to activity has been observed to increase fatty acid oxidation and improve endurance exercise performance (Cha et al.).
  • L-Carnitine supplementation increases antioxidant enzyme production. Specifically, L-Carnitine is a supplement which increases glutathione peroxidase, superoxide dismutase, and catalase – the 3 primary endogenous antioxidant enzymes.

Q: What is the best way to use Acetyl L-Carnitine?

A: As a dietary supplement, consume 1-4 servings (1-4 Capsules) of Acetyl L-Carnitine daily according to your goals. For general health and antioxidant effects, 1-2 servings are sufficient. For endurance and fat metabolism enhancement, consume 2-4 servings per day. For a nootropic effect, consume 4 servings as a single dose.


Q: How does Acetyl L-Carnitine help with Fat Burning?

A: The carnitine molecule is essential for burning fat, which means the body cannot burn body fat without having carnitine. Its function is to move fat from outside the mitochondria to inside the mitochondria. This may not sound like a big deal, but fat cannot be burned outside of the mitochondria, which makes carnitine VERY important.


Q: Is there a best time to use Acetyl L-Carnitine?

A: Depending on your goals, yes. For general wellness, carnitine can be consumed with any meal. For fat burning, carnitine is best taken prior to exercise. For speeding recovery from exercise, carnitine is best taken after exercise.


Q: Can other supplements be stacked with Acetyl L-Carnitine™?

A: Yes! For enhanced nootropic effects, stack Acetyl L-Carnitine™ with Alpha GPC™ and Uridine5™. For enhanced fat-burning effects, stack Acetyl L-Carnitine™ with a fat burner that will increase metabolic rate (calorie burn). For fat-burning supplements, Optitune™ has partnered with MuscleSport and Kodiak Sports Nutrition. Take 30% off with code, "OPTITUNE"
