L-Carnitine--Sunway (Hangzhou) Biotechnology Co., Ltd.

Overview

Product Overview & Core Technical Identity

SUNWAY supplies high-purity L-Carnitine crystalline powder complying fully with USP43 monograph, China GB food additive and feed additive standards. L-Carnitine, also known as Vitamin BT, is a vital metabolic cofactor with strong water solubility and thermal stability. We independently produce food grade, cosmetic grade and feed grade L-Carnitine with strictly controlled heavy metal, solvent residue and microbial limits. Each batch undergoes full HPLC testing and 12-month sample retention for complete quality traceability. Flexible MOQ covers 5kg lab trial orders to ton-level bulk shipments, and mixed consolidated loading with vitamins, amino acids and specialty bioactives is available to cut clients' overall procurement and logistics expenses.

Functions

Physiological Functions & Industry Application Logic

L-Carnitine acts as the core mitochondrial fatty acid transport cofactor, with multi-dimensional metabolic functions across human body, skin and livestock breeding systems:

1.Fat Metabolism & Energy Production It shuttles long-chain fatty acids into mitochondria for beta-oxidation, converting stored fat into usable energy. It accelerates fat decomposition, reduces body fat accumulation and improves lean muscle ratio, the core active ingredient for weight management and sports nutrition formulas.

2.Anti-Fatigue & Sports Performance Boost It reduces lactic acid accumulation during high-intensity exercise, delays central fatigue, enhances endurance and speeds post-workout muscle recovery, widely used in pre-workout and recovery supplements for athletes.

3.Cardiac & Metabolic Protection Optimizes myocardial energy supply, alleviates fatigue caused by insufficient energy metabolism, suitable for middle-aged and elderly cardiovascular care nutritional products.

4.Skin Anti-Aging & Local Fat Regulation (Cosmetic Use) Transdermally promotes subcutaneous fat decomposition, improves cellulite and uneven body contour; neutralizes free radicals to relieve UV oxidative damage, repairs skin barrier and brightens dull complexion.

5.Animal Breeding Performance Improvement Promotes livestock & aquatic fat metabolism, reduces feed coefficient, improves meat/egg quality, relieves breeding stress and increases survival rate of young animals, a cost-effective feed nutrition additive.

Storage

Storage, Handling & Shelf Life Guidance

Standard Storage Environment

Store unopened original packaging in cool, dry, ventilated warehouse with controlled temperature 10-25C and relative humidity <=60%. Keep far away from direct sunlight, high-temperature equipment and oxidants. L-Carnitine is highly hygroscopic, so strict moisture isolation is required.

Post-Opening Handling Tips

Seal packaging tightly immediately after each use, and finish consumption within 30 days to prevent moisture absorption, caking and purity decline. For large 25kg drums, nitrogen blanketing treatment is recommended for long-term half-opened storage.

Special Operation Reminder

Avoid drastic temperature fluctuations to reduce moisture absorption risk; no heating treatment is needed under normal warehouse storage conditions.

Valid Shelf Life

24 months under intact sealed standard storage conditions; all purity and microbial indicators are fully guaranteed within the expiry date.
