L-Carnitine Ingredient
L-Carnitine Manufacturer & Bulk L-Carnitine Supplier
L-Carnitine is available in different forms for nutritional and sports-nutrition formulations. L-Carnitine L-Tartrate is one of the established forms, supplied as a white crystalline ingredient with defined composition and analytical specifications.
Product Information
L-Carnitine L-Tartrate
A defined L-Carnitine salt form with a clear chemical identity and established composition.
About the Ingredient
A Practical Choice When the Formula Calls for L-Carnitine L-Tartrate
L-Carnitine L-Tartrate combines L-Carnitine with L-tartaric acid in a defined salt form. It is therefore specified and evaluated differently from free L-Carnitine or other Carnitine forms.
Why the Form Matters
Carnitine products are not interchangeable simply because they share the L-Carnitine name. For a formulation, the selected form should match the ingredient specification, the intended dosage format and the way the active material is calculated in the finished product.
What You Can Expect From the Product
This L-Carnitine L-Tartrate is supplied as a white crystalline material and is characterized by defined composition, optical rotation, pH, moisture-related controls, contaminant limits and physical properties.

Applications
Where L-Carnitine L-Tartrate Is Used
L-Carnitine ingredients are incorporated into a range of nutritional products. The final ingredient choice depends on the form required by the formulation.
Dietary Supplements
Used as a Carnitine ingredient in nutritional formulas where L-Carnitine L-Tartrate is the specified form.
Sports Nutrition
Used in sports-nutrition formulas as part of powder, capsule, tablet and other finished-product formats.
Capsules & Tablets
A suitable option where the formulation calls specifically for L-Carnitine L-Tartrate in a solid dosage format.
Powder Formulations
Incorporated into dry blends where the composition and physical characteristics of the ingredient fit the formulation.
For Your Formulation
What to Check When Choosing the Ingredient
The right specification is the one that fits the finished product, not simply the one with the highest headline number.
Start With the Form
First confirm that L-Carnitine L-Tartrate is the form required by the formulation. Free L-Carnitine and other Carnitine salts have different specifications and should be evaluated separately.
Then Review the Specification
Once the form is confirmed, look at the analytical details that matter to qualification and processing.
Packaging & Documentation
Product Information for Your Order
Clear product information makes it easier to evaluate the ingredient before placing an order.
Packaging
The product is documented in a 25 kg bucket format. Packaging requirements can be confirmed according to the order.
Certificate of Analysis
A product COA provides the analytical information needed to review identity, composition, quality controls and physical properties before approval.
