Product Features & Scientific Advantages

1. Superior Metabolic Catalyst

Acts as an essential cofactor for transporting long-chain fatty acids into mitochondria, facilitating efficient beta-oxidation and ATP production. This makes it a critical ingredient for energy-promoting supplements and sports drink ingredients.

2. Enhanced Stability for Processing

The tartrate salt form provides exceptional stability against heat, moisture, and pH variations compared to L-Carnitine base or fumarate. This ensures potency retention during the manufacturing of baked goods, powdered mixes, and acidic beverages.

3. Synergistic with Other Actives

Compatible and often synergistic with a wide range of functional ingredients. It can be effectively combined with plant extract antioxidants for enhanced recovery, or with energy substrates like food grade trehalose for comprehensive endurance formulations.

4. Multi-Targeted Health Benefits

Beyond sports nutrition, it supports cardiovascular health, cognitive function, and healthy aging by optimizing cellular energy metabolism. Its antioxidant properties help mitigate oxidative stress, complementing other natural antioxidants in a formulation.

How to Formulate with L-Carnitine L-Tartrate: A Step-by-Step Guide

Dosage Calculation & Potency Adjustment
Determine your target L-Carnitine delivery per serving. Remember, our product contains 68.2% active L-Carnitine. Use the formula: Amount of L-Carnitine L-Tartrate = Target L-Carnitine Dose / 0.682. For a 1000mg L-Carnitine dose, use approximately 1466mg of our product.
Compatibility & Pre-Blending
For dry mixes (powders, protein blends), pre-mix the L-Carnitine L-Tartrate with other dry carriers (like maltodextrin or silica) to ensure uniform distribution before adding to the main batch. Check compatibility with sensitive ingredients.
Integration & Processing
For liquids: Dissolve in water at room temperature with moderate agitation. Its high solubility ensures clear solutions. For tablets/capsules: Blend thoroughly with excipients. Monitor the mild acidity (pH 3.0-4.5) which can act as a stabilizer in some systems.
Quality Verification & Labeling
Conduct final product assays to verify L-Carnitine content. Ensure your labeling reflects the correct compound name and declared active amount, complying with regional regulations (e.g., FDA, EFSA).

Frequently Asked Questions (FAQ) for Buyers

Q: What is the key difference between L-Carnitine Base, L-Tartrate, and Fumarate?

A: The base form is hygroscopic and less stable. L-Tartrate offers the best combination of stability, solubility, and bioavailability for most food and supplement applications. Fumarate is also stable but has different solubility and compatibility characteristics. Tartrate is generally preferred for sports nutrition and functional beverages.

Q: How do you ensure consistency in the 68.2% L-Carnitine content?

A: Through precise stoichiometric control during synthesis and validated analytical methods (like HPLC) for every batch. The Certificate of Analysis (CoA) provided with each shipment confirms the exact assay value.

Q: Can this ingredient be used in cosmetic applications?

A: While its primary use is in nutritional products, L-Carnitine has applications in cosmetics for its potential skin benefits. We supply it as a high-purity ingredient. Please consult with us for specific cosmetic raw materials documentation if intended for topical use.

Q: What is the MOQ, lead time, and packaging?

A: Standard Minimum Order Quantity is 25 kg. Lead time is typically 2-4 weeks after order confirmation. Standard packaging is in 25 kg fiber drums with double polyethylene liners. Custom packaging is negotiable for larger orders.

Q: Do you offer blend customization, like combining it with other actives?

A: Yes. Hersoncare specializes in creating custom premixes. We can expertly blend L-Carnitine L-Tartrate with other vitamins & minerals, natural antioxidants, or plant extract ingredients to create a tailor-made, single-powder solution for your specific formulation, saving you time and ensuring homogeneity.
