L-Carnitine L-Tartrate

What Is L-Carnitine L-Tartrate?

L-Carnitine L-Tartrate (LCLT) is a salt formed by combining L-Carnitine with L-Tartaric acid in a 1:1 molar ratio. The tartrate salt form is more stable than L-Carnitine Base (free form), significantly less hygroscopic, and flows more readily as a powder — making it the preferred form for tablet and capsule manufacturing where L-Carnitine Base's moisture sensitivity would create production challenges.

The biological activity comes from the L-Carnitine component. Tartaric acid is an organic acid found naturally in fruits and is a normal component of food metabolism — it does not contribute additional ergogenic activity but also does not interfere with L-Carnitine's function.

Specification & Form

How It's Sourced

YNP Ingredients sources L-Carnitine L-Tartrate from certified manufacturers in China, supplied in drum packaging with FSSAI-compliant documentation.

Applications

• Capsule and tablet sports nutrition supplements (preferred form due to handling stability)
• Pre-workout and recovery products
• Weight management and energy metabolism supplements
• Powder sachets and stick packs (where hygroscopicity must be managed)

Industries Served

Sports Nutrition · Nutraceuticals/Dietary Supplements

Buyer Checklist

• Dose calculated as L-Carnitine equivalents (~68% of the tartrate salt weight) — label declarations must reflect actual L-Carnitine content
• Confirmed LCLT is appropriate for dosage form (solid dosage preferred; if liquid, L-Carnitine Base dissolves more readily)
• COA confirming assay as L-Carnitine %
• FSSAI-compliant documentation and 25 kg drum confirmed

Common Mistakes

Dosing based on total salt weight rather than L-Carnitine equivalent. A 500 mg LCLT capsule provides approximately 340 mg L-Carnitine — relevant for both labeling accuracy and matching studied doses.

Choosing LCLT for liquid formulations without checking solubility. L-Carnitine Base dissolves more readily and may be preferable in liquid supplement formats.
