• Helps Metabolize Fat Into Energy*
• Supports Cardiovascular Function*

How It Works: 

Twinlab® Mega L-Carnitine is a dietary supplement that nutritionally has a role in metabolizing fat into energy.* L-carnitine can promote muscle mass and help reduce fatigue.* In the body, L-carnitine is produced by the liver and kidneys and is stored in the skeletal muscles, heart and brain. L-carnitine also supports cardiovascular function and helps reduce oxidative stress.* Twinlab Mega L-Carnitine contains CARNIPURE® brand L-carnitine, and does not contain any synthetic D-Carnitine or DL-Carnitine, which are less effective.

This product contains no added starch, corn, yeast, wheat, flavors, colors, derivatives or preservatives.

Suggested Use: 

Take 1 tablet 1-4 times daily or as directed by a health care professional. To achieve the clinically shown results of L-Carnitine, including helping metabolize fat into energy and supporting cardiovascular function, taking 4 tablets daily is recommended.* KEEP OUT OF REACH OF CHILDREN.

• Easier to Swallow and Assimilate

How It Works: 

L-arginine is a free-form amino acid that is needed to create both creatine and urea, a waste product that is necessary for the removal of ammonia from the body.* While the body typically manufactures enough l-arginine, it is considered a semi-essential amino acid as supplementation is sometimes needed.* Arginine is a precursor to nitric oxide, which causes relaxation of the blood vessels, and also plays a key role in the production of protein.* Each capsule contains 500 mg of L-arginine. No tablet binders, coatings or added flavorings, salt, artificial sweeteners, colorings, preservatives or salicylates.

Suggested Use: 

Take one capsule daily or as directed by a health care professional.

• Enhances Cognitive Function and Physical Performance*

How It Works: 

Acetyl L-Carnitine is the acetyl ester of L-carnitine, and is a source of both L-carnitine and an acetyl group. In its role as a precursor for the formation of acetylcholine (an important neurotransmitter), this compound helps maintain cognitive functions.* This nutrient also facilitates the transport of long-chain fatty acids to enable beta-oxidation and energy generation, thus supporting physical performance.*

Suggested Use: 

Take 1 capsule 1-4 times daily or as directed by your health care professional. To achieve the clinically supported results of Enhancing Cognitive Function and Physical Performance*, taking a total of 4 capsules daily is recommended. KEEP OUT OF REACH OF CHILDREN.
