L-Carnitine Magnesium Citrate
L-Carnitine Magnesium Citrate is a combined ingredient that pairs L-carnitine with magnesium citrate in a single salt complex, delivering both the β-oxidation cofactor and a bioavailable form of magnesium in one powder. It is positioned for muscle energy, recovery, and cardiovascular formulations where supplementing magnesium alongside carnitine is a common formulation strategy.
The material is a white to off-white crystalline powder, with carnitine content typically around 35 to 40 percent and elemental magnesium of 9 to 11 percent depending on the supplier's stoichiometry.
We source bulk L-Carnitine Magnesium Citrate from top China manufacturers for our partners. The manufacturer is in Liaoning. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
L-Carnitine Magnesium Citrate trades in one grade, food-supplement.
Standard specifications cover L-carnitine content by HPLC, magnesium content by titration or ICP, citrate content by HPLC, loss on drying, residual solvents, and heavy metals. Suppliers differ on the precise stoichiometry, so users should check the certificate of analysis for the exact carnitine and magnesium contribution.
Particle size is typically a fine to medium powder suitable for capsule fill, stick pack, and tablet compression after blending with standard excipients.
The complex has reasonable flow, modest hygroscopicity, and a mildly salty-tart taste profile that is compatible with citrus and berry flavour systems.

How We Help Source L-Carnitine Magnesium Citrate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your L-Carnitine Magnesium Citrate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load L-Carnitine Magnesium Citrate together with other ingredients such as Glycine, L-Arginine and L-Leucine into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
L-Carnitine Magnesium Citrate is permitted in food supplements in the European Union as a combined source of L-carnitine and magnesium, with both component salts already covered under Annex II of the Food Supplements Directive (2002/46/EC).
In the United States it is sold as a dietary ingredient under DSHEA. Both L-carnitine and magnesium citrate carry long-standing safe-use history in supplements, which simplifies regulatory positioning of the combined complex.
Labelling typically declares each contribution separately, with the L-carnitine claim against the carnitine fraction and the magnesium claim against the elemental magnesium fraction.
Halal and Kosher certifications are routinely available. Suppliers provide full documentation supporting use in food supplements and functional foods.
Manufacturing Process
L-Carnitine Magnesium Citrate is produced by reaction of L-carnitine free base, magnesium oxide or carbonate, and citric acid in aqueous medium, followed by crystallisation or spray drying.
The stoichiometry is controlled to deliver the target ratio of L-carnitine to magnesium to citrate, and the reaction is run with pH monitoring to ensure full neutralisation. Several supplier-specific complexes exist, including 1:1:1 and other variants.
L-carnitine is sourced from the standard asymmetric synthesis or biocatalytic routes, magnesium from food-grade oxide or carbonate, and citric acid from fermentation by Aspergillus niger.
Final product is dried under controlled conditions, milled, and sieved. Microbiological quality is monitored carefully because the aqueous processing and modest sugar-like behaviour can support growth if water activity is not adequately reduced.
