Description
The dihydrogen citrate salt of choline, an alternative choline source for human dietary supplements and pharmaceutical applications. Distinct from Choline Bitartrate by counter-ion choice, providing similar handling and sensory advantages over Choline Chloride.
White to off-white crystalline powder. Non-hygroscopic; suitable for direct tablet and capsule manufacturing.
We supply food-grade and pharmaceutical-grade Choline Dihydrogen Citrate from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Standard Food Grade and Pharmaceutical Grade. The citrate counter-ion contributes mild acidity that some formulators prefer over the tartrate form in specific finished-product applications.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, moisture, heavy metals, and microbiology.
Introduction
Choline Dihydrogen Citrate is the dihydrogen citrate salt of choline, an alternative to Choline Bitartrate as the preferred human-supplement choline source.
Industrial production proceeds by reaction of choline base with food-grade citric acid, followed by crystallization to the dihydrogen citrate form.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide.
Choline content by mass is approximately 35 percent, lower than Bitartrate (41 percent) and Chloride (75 percent), reflecting the larger citrate counter-ion. The citrate counter-ion contributes mild acidity that supports use in effervescent tablet formulations where the citrate serves a dual function as both choline carrier and acid-base buffer component.
Strategic positioning serves specialty supplement applications, particularly effervescent and acidic-finished-product formulations where the citrate counter-ion adds functional value beyond the choline contribution.
Where it is used
- Dietary supplements: standalone choline and B-complex formulations
- Pharmaceutical tablets, capsules, and oral solutions
- Sports nutrition and pre-workout formulations
- Premium fortified beverages
- Clinical nutrition formulas where citrate counter-ion is preferred
- Effervescent tablet formulations leveraging citrate's acid-base buffer function
- Cognitive-health and brain-support supplement formulations
