什麼是左旋肉鹼？
L-Carnitine is a defined quaternary ammonium compound commonly sourced as a specialty supplement ingredient in base, tartrate, fumarate or acetylated forms.
左旋肉鹼 is also known as Levocarnitine, L-Carnitine Base, Carnitine or Vitamin BT in some technical documents. In supplement raw material sourcing, the buyer should confirm the exact form because L-Carnitine Base, L-Carnitine L-Tartrate, L-Carnitine Fumarate and Acetyl-L-Carnitine HCl have different CAS references, molecular weights, assay calculations, moisture behavior, taste profiles, formulation behavior and label declaration requirements. Buyers usually evaluate L-Carnitine by chemical identity, assay, specific rotation, pH, water content, particle size, bulk density, solubility, residual solvents, heavy metals, microbiology, packaging, storage condition and destination market label requirements.
Defined Ingredient Identity
L-Carnitine sourcing should confirm CAS number, exact salt or free base form, assay method, specific rotation and batch documentation.
Form Selection Matters
Base, L-tartrate, fumarate and acetyl forms are not interchangeable for specification, label amount, moisture control or dosage-form design.
營養補充品供應重點
Gensei supports supplement brands, OEM factories and contract manufacturers with bulk L-Carnitine sourcing and technical documentation.
L-Carnitine Specification Options
Final specifications depend on L-Carnitine form, assay basis, salt form, purity target, particle size, moisture control, packaging and destination market requirements.

什麼是左旋肉鹼？
L-Carnitine is a defined ingredient also known as Levocarnitine, L-Carnitine Base, Carnitine or Vitamin BT. In supplement raw material sourcing, it is commonly evaluated by exact form, assay, specific rotation, pH, water content, particle size, solubility, residual solvents, heavy metals, microbiology and batch COA.
What is the CAS number of L-Carnitine?
The CAS number commonly used for L-Carnitine Base is 541-15-1. L-Carnitine L-Tartrate, Acetyl-L-Carnitine HCl and L-Carnitine Fumarate have different CAS references and should be reviewed separately.
What is the molecular formula of L-Carnitine Base?
The molecular formula commonly referenced for L-Carnitine Base is C7H15NO3, with molecular weight around 161.20 g/mol.
What is the difference between L-Carnitine Base and L-Carnitine L-Tartrate?
L-Carnitine Base is the free base or inner salt form, while L-Carnitine L-Tartrate is a salt form with tartaric acid. They differ in molecular weight, equivalent L-Carnitine content, moisture behavior, formulation behavior and label declaration.
What is the difference between L-Carnitine and Acetyl-L-Carnitine?
Acetyl-L-Carnitine is an acetylated form of L-Carnitine and is usually supplied as Acetyl-L-Carnitine HCl. It has a different CAS reference, molecular weight, assay basis and label identity, so it should not be treated as the same specification as L-Carnitine Base.
Is L-Carnitine water soluble?
Many L-Carnitine forms are water soluble, but finished formula performance should still be tested for clarity, pH, taste, active uniformity and stability.
Is L-Carnitine hygroscopic?
Some L-Carnitine forms can be moisture sensitive or hygroscopic. Buyers should review water content, packaging, desiccant strategy, storage condition and finished-product stability.
Can L-Carnitine be used in capsules or tablets?
Yes. Selected L-Carnitine specifications can be evaluated for capsules and tablets when serving size, bulk density, flowability, compression behavior, moisture control and stability are suitable.
Can L-Carnitine be used in drink powders?
L-Carnitine can be evaluated for drink powders, sachets and stick packs. Formulators should review solubility, pH, flavor compatibility, bitterness, aftertaste, moisture protection and active retention.
Can L-Carnitine be used in gummies?
L-Carnitine can be evaluated for gummy concepts, but heat, pH, taste, moisture, color impact, active retention and packaging should be tested carefully before launch.
Is L-Carnitine vegan?
Vegan suitability depends on production route, raw materials, processing aids, carriers and manufacturing conditions. Buyers should request a vegan statement if vegan label positioning is required.
下單前我可以索取哪些文件？
Qualified B2B buyers can request COA, specification sheet, SDS, TDS, allergen statement, non-GMO statement, vegan statement, flow chart, residual solvent report, stability information and other technical files depending on the selected grade.
How should L-Carnitine powder be stored?
L-Carnitine powder should generally be stored sealed in a cool, dry and light-protected environment. Avoid moisture, heat, direct sunlight and strong odors.
Does Gensei supply L-Carnitine for medical, pharmaceutical or animal feed use?
This page is focused on B2B dietary supplement ingredient sourcing. If a project involves pharmaceutical, medical food, animal feed or therapeutic applications, the required grade, documentation and regulatory pathway should be confirmed separately.
