Product Info
What is L-Carnitine L-Tartrate?
L-Carnitine L-Tartrate is a stable and rapidly absorbed salt form of the amino acid derivative L-Carnitine, which is widely used in dietary supplements to enhance fat metabolism and support muscle recovery, especially in sports nutrition.
How is L-Carnitine L-Tartrate made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Raw Material Charging | L-Tartaric Acid and a suitable solvent (e.g., purified water or ethanol) are charged into a clean reaction vessel. | Control Point: Purity and assay of incoming L-Carnitine and L-Tartaric Acid. Note: Accurate weighing is critical to maintain the required 2:1 molar ratio of L-Carnitine to L-Tartaric Acid for the final salt. |
| 2 | Salt Formation Reaction | L-Carnitine base is slowly added to the L-Tartaric Acid solution under controlled agitation and temperature. | Control Point: Maintain reaction temperature (e.g., 50-70°C) and monitor the solution's pH, adjusting to a target range (e.g., 5.5 - 6.5) to ensure complete salt formation. |
| 3 | Crystallization | The reaction solution is gradually cooled down according to a pre-defined profile to induce the crystallization of the L-Carnitine L-Tartrate salt. | Control Point: The cooling rate and final holding temperature (e.g., 0-5°C) are crucial for controlling crystal size, purity, and maximizing product yield. |
| 4 | Centrifugation & Washing | The crystallized slurry is fed into a centrifuge to separate the solid product from the mother liquor. The solid cake is then washed with a cold solvent. | Control Point: Ensure efficient separation and complete removal of impurities. Note: The wash solvent (e.g., cold ethanol) must be chilled to prevent re-dissolving the product. |
| 5 | Drying | The wet solid product is transferred to a vacuum dryer to remove residual solvent until a constant weight is achieved. | Control Point: Monitor Loss on Drying (LOD) to ensure it meets the specification (e.g., < 1.0%). Drying temperature is kept low (e.g., < 60°C) to prevent thermal degradation of the product. |
| 6 | Milling & Sieving | The dried, coarse L-Carnitine L-Tartrate is milled and then passed through a mechanical sieve of a specific mesh size. | Control Point: Verify the sieve mesh size (e.g., 40/60 mesh) to ensure the final product meets the required particle size distribution for flowability and solubility. |
| 7 | Final QC & Packaging | A representative sample of the finished batch is tested against all specifications. The approved product is packaged into sealed, multi-layer bags within drums. | Control Point: Final analysis must confirm compliance with all parameters, including Assay (typically >98%), specific rotation, heavy metals, and microbial limits. Note: Packaging must protect the product from moisture, light, and contamination. |

supports fat metabolism
energy production
antioxidant
Mechanism of action:
| Parameter | L-Carnitine L-Tartrate |
|---|---|
| Functional Category | Nutrient Fortificant; Stabilizer; pH Regulator |
| Key Ingredients | L-Carnitine; L-Tartaric Acid |
| Mechanism of Action | As a fortificant, L-Carnitine facilitates mitochondrial fatty acid transport for energy metabolism. As a salt, the L-tartrate component stabilizes the highly hygroscopic L-carnitine, improving its physical properties and shelf life. The tartrate moiety also acts as an acidulant, contributing to pH control and tartness. |
| Application Effect in Product | Nutritional fortification of functional foods and beverages (e.g., energy drinks, nutritional bars); improved powder flowability and reduced clumping in dry blends; enhanced stability and shelf life of the active ingredient; provides a clean, tart taste profile and aids in pH adjustment. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| L-Carnitine L-Tartrate | Amino Acid Supplement | L-Carnitine bonded with tartaric acid. Rapidly absorbed. | Highest absorption rate. Extensively studied for reducing muscle soreness and improving exercise recovery. | Does not readily cross the blood-brain barrier; minimal cognitive benefits compared to ALCAR. | Post-workout recovery, reducing exercise-induced muscle damage, enhancing androgen receptor sensitivity. | For an athlete or individual focused primarily on physical performance, muscle recovery, and reducing soreness. |
| Acetyl-L-Carnitine (ALCAR) | Amino Acid Supplement | Acetylated form of L-Carnitine. | Readily crosses the blood-brain barrier, providing significant nootropic and neuroprotective effects. | Less studied for direct physical performance metrics like muscle recovery compared to L-Carnitine L-Tartrate. | Cognitive enhancement, improving focus and mental clarity, supporting brain health and nerve function. | When the main goal is cognitive support, mental energy, or neurological health. |
| Glycine Propionyl-L-Carnitine (GPLC) | Amino Acid Supplement | L-Carnitine bonded with glycine and a propionyl ester. | Increases nitric oxide (NO) levels, which improves blood flow and vascularity. Potent antioxidant. | Often more expensive. Benefits are more specialized towards blood flow and pumps. | Pre-workout for enhanced blood flow (pump), improving anaerobic work capacity, and circulation support. | For users seeking improved workout pumps, better blood flow, and enhanced short-burst performance. |
| L-Carnitine Fumarate | Amino Acid Supplement | L-Carnitine bonded with fumaric acid. | Provides fumarate, a key intermediate in the Krebs cycle, supporting cellular energy production. Very stable form. | Slower absorption compared to L-Tartrate. Less research focused specifically on athletic recovery. | Supporting overall cellular energy, cardiovascular health, and addressing carnitine deficiency. | For general wellness, stable energy levels, and synergistic support for cardiovascular function. |
