Product Description
Coated L(+)‑Choline Bitartrate is a micro‑encapsulated choline nutrient salt manufactured via advanced particle coating technology. Unlike conventional uncoated choline bitartrate, the protective outer shell greatly cuts down moisture absorption, suppresses unpleasant trimethylamine‑related odor generation during long‑term storage, and dramatically improves powder flow performance for industrial formulation workflows.
Choline serves as a fundamental essential nutrient for human and animal physiology. It acts as building units for phosphatidylcholine that constructs cell membrane architecture, and acetylcholine, the key neurotransmitter supporting neural signal transmission. Within metabolic pathways, choline delivers methyl groups for one‑carbon metabolism, facilitates lipoprotein assembly to boost liver lipid export, and mitigates excess fat buildup inside hepatic tissues.
Thanks to surface modification, this coated grade performs excellently for dry mixing, tablet direct compression, and feed premix production. It avoids common processing troubles such as powder caking, sticking, and tablet capping caused by high hygroscopicity of native choline bitartrate. The product keeps high water‑soluble property while gaining better handling stability for solid‑form finished goods.

Everything You Need to Know
Q1: How does micro‑coated choline bitartrate differ from standard uncoated choline bitartrate in practical production?
A: Uncoated choline bitartrate absorbs moisture easily and tends to cake, releasing fishy odor upon storage. The micro‑coated variant minimizes moisture uptake, restrains odor development, improves powder flow, and brings much better adaptability for tablet compression and feed premixing work flows.
Q2: Can this coated choline bitartrate be applied for direct compression tablet production?
A: Yes. Optimized flowability and anti‑sticking feature reduce capping and sticking defects during direct compression, perfectly matching dry‑tablet manufacturing processes.
Q3: What is the shelf‑life condition for coated choline bitartrate?
A: Keep sealed in cool, dry and well‑ventilated storage environment, avoid direct sunlight and high humidity. Under proper storage condition, shelf‑life reaches 24 months.
Q4: Can you adjust particle size and coating layer thickness according to customer formulation needs?
A: Sure. Our R&D workshop supports tailored coating proportion and particle‑size distribution. Please provide your mixing or pressing equipment requirements so we can recommend suitable specs.
Q5: Is coated choline bitartrate Halal & Kosher certified?
A: Yes. Halal and Kosher certificates are available upon request. This material is also non‑GMO, allergen‑free and anti‑doping compliant.
Q6: What possible adverse reactions may appear for human oral intake of choline bitartrate?
A: Under recommended dosage, adverse reactions rarely occur. Excessive intake may trigger mild gastrointestinal discomfort or fishy odor from trimethylamine metabolism. Pregnant, lactating population or people with underlying medical conditions should consult health professionals before developing human‑use finished products.
Q7: Which shipping options are available for coated choline bitartrate bulk orders?
A: We provide 3 shipping modes: international express for small‑weight orders, air freight for medium bulk cargo, and ocean freight for heavy‑weight large shipments. Relevant customs documents will be supplied.
Q8: Could I get free samples for lab testing?
A: Yes, free samples are available for quality & formulation validation. Please send inquiry with your contact information and sample quantity requirement, our team will arrange sample delivery for you.
