There are many aspects to fat loss. One of which is the transportation of fatty acids to the mitochondria (organelles found inside our cells), where fats are broken down and harvested for energy – aka burning fat. The mitochondria have a gatekeeper, however, known as L-Carnitine. With more L-Carnitine, our body’s ability to burn fats is enhanced. That’s not all L-Carnitine is good for:


  • Carnitine helps supply energy during exercise, improving performance.*
  • Supplementing with L-Carnitine has been shown to increase the body’s antioxidant enzymes.*
  • Using L-Carnitine after exercise reduces soreness and speeds recovery.*
  • L-Carnitine may promote glucose management by reducing blood glucose and enhancing insulin sensitivity.*


Despite L-Carnitine’s well-known function in weight loss and body fat reduction, its other effects added on top of enhanced fat-burning are what make L-Carnitine a must-have supplement. With increased fat metabolism, improved anti-oxidant profile, exercise performance and recovery enhancement, glucose management, hormone optimization, and even more benefits, L-Carnitine should be considered for all types of individuals seeking improved health.

Ingredient Profile


L-Carnitine is dipeptide (2 amino acid) compound that is essential as part of the fatty acid breakdown process and has several other helpful actions.


  • Consuming Carnitine prior to activity has been observed to increase fatty acid oxidation and improve endurance exercise performance (Cha et al.).
  • Supplementation with L-Carnitine has been demonstrated to reduce muscle soreness and muscle damage after exercise.
  • Supplementation with L-Carnitine daily for just one week was able to reduce markers of muscle damage after resistance exercise while also reducing oxidative damage.
  • 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.


Thiamine (Vitamin B1)

As one of the B vitamins, thiamine plays a major role in energy metabolism. Thiamine also prevent the disease, beriberi.


  • Promotes optimal neuron health and nervous system function
  • Helps produce the energy molecule, ATP
  • Plays a key role in metabolizing fats and carbs



L-Methionine is an amino acid which forms an important compound known as S-Adenosyl Methionine (SAMe).


  • Methionine with carnitine may improve mood.
  • As a sulfur containing amino acid, methionine may improve joint health
  • Helps form the antioxidant enzyme, glutathione

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

A: As a dietary supplement, consume 1-4 servings (1-4 Capsules) of 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.


Q: Should L-Carnitine be consumed with meals?

A: Yes. Carnitine absorption is enhanced when consumed with other foods.


Q: Can I get L-Carnitine in my diet?

A: Yes, but in very small quantities. Animal sources contain the most carnitine (because it is found in muscle tissue). Even a whole serving of pork only contains 24mg of L-Carnitine. Other than pork, only beef contains more than 10mg of L-Carnitine per serving, making food ineffective for reaching optimal L-Carnitine dosage.


Q: What supplements can I stack with L-Carnitine?

A: L-Carnitine goes well with CLA 1,000MG for both muscle recovery and fat burning purposes. L-Carnitine also enhances the effects of other muscle recovery and building supplements, such as protein or amino acids, and it can be used with thermogenic supplements to help increase calories burned as body fat.
