Description

L-Carnitine Fumarate is a high-purity, stable salt form of L-Carnitine, a naturally occurring amino acid derivative essential for fatty acid metabolism. This compound is valued for its enhanced stability and bioavailability compared to other carnitine salts, making it a preferred ingredient in demanding formulations. It serves as a critical raw material for manufacturers in the pharmaceutical, nutraceutical, and functional food industries seeking reliable, high-quality active ingredients.

Application

• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) in medications for treating carnitine deficiency and supporting metabolic functions.
• Dietary Supplements & Nutraceuticals: A key component in capsules, tablets, and powders aimed at weight management, sports nutrition, and energy enhancement.
• Functional Food & Beverage Fortification: Incorporated into health drinks, nutrition bars, and fortified foods to boost L-carnitine content.
• Clinical Nutrition: Utilized in parenteral and enteral nutrition products for patients with specific metabolic needs.
• Veterinary Supplements: Applied in animal health products to support energy metabolism in livestock and companion animals.
• Cosmeceutical Research: Investigated for potential applications in topical formulations for skin vitality and anti-aging properties.

Quality Control

Our L-Carnitine Fumarate is manufactured under strict quality management systems. It is produced to meet exacting standards suitable for pharmaceutical and food-grade applications. Each batch is tested to ensure compliance with specifications for identity, purity, and potency. Certificates of Analysis (COA) are provided and can be tailored to meet specific pharmacopoeial standards such as USP or EP upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a low-humidity environment to prevent caking and degradation.
