Every L-Carnitine batch is HPLC-verified for purity and optical rotation, tested for heavy metals and microbial safety, and shipped with full documentation.
HPLC purity (≥99%), optical rotation ([α]D ≥ +29°), and IR identification confirmed per batch.
Heavy metals (lead, arsenic, mercury, cadmium) and microbial panel (TPC, E.coli, Salmonella) per USP standards.
L-isomer (not D-Carnitine) confirmed by optical rotation. D-Carnitine is biologically inactive and contraindicated.
COA, MSDS, Phytosanitary Certificate, and full export documents prepared before every shipment.
Not all L-Carnitine forms are interchangeable. The correct choice depends on your target health benefit, formulation format, and consumer segment. Understanding the differences between forms is critical to both product efficacy and label claim compliance.
The pure free-form amino acid derivative. Highest carnitine content per gram. Ideal for capsules, tablets, and liquid supplement formulations where maximum carnitine delivery per serving is the priority. Slightly hygroscopic — requires moisture-controlled processing.
Salt form with superior flow properties and faster absorption kinetics. The #1 form used in sports nutrition. Excellent stability and flowability for powder blends, stick packs, and pre-workout formulations. Preferred by sports supplement brands globally.
Acetylated form that crosses the blood-brain barrier. Supports acetylcholine synthesis and mitochondrial function in neural tissue. The correct form for nootropic, cognitive health, age-related cognitive decline, and diabetic neuropathy formulations.
Specialised form for cardiovascular and peripheral circulation applications. Studied in clinical trials for angina pectoris, peripheral artery disease, and heart failure support. Less common in general sports nutrition; targeted at clinical and Rx-adjacent products.
