What is L-carnitine L-tartrate?
L-carnitine L-tartrate (LCLT) is a highly bioavailable form of L-carnitine bound with L-tartaric acid, identified by CAS number 36687-82-8. Also known as LCLT, L-carnitine tartrate, or carnitine tartrate, it has the molecular formula C₁₁H₂₀N₂O₈ and a molecular weight of 308.29 g/mol. Unlike some carnitine forms derived from animal sources, LCLT is primarily produced synthetically. It appears as a white to off-white crystalline powder with a characteristic mild odor, and offers superior bioavailability compared to standard L-carnitine, with studies showing approximately 15-20% better absorption rates and faster uptake into the bloodstream. The typical commercial specification includes minimum 68% L-carnitine content, with purity exceeding 98%. Provita Biotech stands as the leading bulk L-carnitine L-tartrate powder supplier in China, providing high-quality material that meets international standards for dietary supplements and sports nutrition products.
L-carnitine Tartrate vs L-carnitine
L-carnitine L-tartrate (LCLT) generally offers advantages over standard L-carnitine for most applications. LCLT provides superior bioavailability (15-20% higher absorption), faster uptake into the bloodstream, greater stability in various formulations, and enhanced exercise recovery benefits. While LCLT comes at a premium price point (typically 15-30% more expensive), its improved absorption characteristics may provide better value for money in performance-focused supplements. Standard L-carnitine remains a cost-effective option for basic supplementation needs, but LCLT is the preferred choice for sports nutrition products and premium dietary supplements where absorption efficiency and performance benefits are paramount.

Application
Sports Performance
L-carnitine L-tartrate is prized by athletes for its role in enhancing energy utilization and reducing muscle soreness, helping to accelerate recovery after intense workouts. Its rapid absorption supports efficient delivery of carnitine to muscles, promoting improved endurance and performance.
Cardiovascular Support
L-carnitine L-tartrate helps maintain healthy heart function by optimizing fatty acid oxidation and energy production in heart muscle cells. Adequate levels of L-carnitine may contribute to better cardiovascular health and overall vitality.
Weight Management
By assisting in the transport of fatty acids into the mitochondria, L-carnitine L-tartrate encourages more effective fat burning. This metabolic boost can aid weight management efforts when combined with a balanced diet and regular exercise.
L-carnitine L-tartrate Powder Manufacturing Process
Starting Material Preparation:
- The process begins with S,R-epichlorohydrine, which is a racemic mixture of epichlorohydrine isomers.
Hydrolytic Kinetic Resolution:
- The racemic mixture undergoes hydrolytic kinetic resolution.
- This stereoselective process separates the racemic mixture into its enantiomers.
Isolation of S-epichlorohydrine:
- The S-(+)-epichlorohydrine is isolated from the resolution process.
- This is a critical step as the S-isomer is required for producing L-carnitine.
Chemical Reaction:
- The S-epichlorohydrine undergoes a series of chemical reactions involving:
- Nucleophilic substitution
- Oxidation
- Trimethylamine addition
- These reactions transform the epichlorohydrine into L-carnitine.
- The S-epichlorohydrine undergoes a series of chemical reactions involving:
Formation of L-Carnitine and Sodium Chloride Solution:
- The reaction produces a water solution containing L-carnitine and sodium chloride.
Purification Process:
- Sodium chloride removal: Ion exchange chromatography or selective precipitation techniques are employed.
- Crystallization: The L-carnitine solution is concentrated and crystallized under controlled conditions.
- Drying: The crystals are dried using vacuum drying or freeze-drying methods to obtain L-Carnitine Base.
L-Tartrate Addition:
- L-Tartaric acid is added to the purified L-Carnitine base.
- This forms L-Carnitine L-Tartrate through an acid-base reaction.
Final Processing (supplemented from professional knowledge):
- Secondary crystallization to achieve high purity
- Fine milling to achieve uniform particle size
