Citicoline Sodium made by Xi'an DN Biology Co., Ltd. is 98% pure and is pharmaceutical-grade. The company is certified by ISO, GMP, HACCP, and KOSHER. As a specialized manufacturer that has been around since 2010 and has done research and development for over ten years, we use modern HPLC and GC analytical systems to process up to 3,000 tons of material every year. Our factory has four 6m³ extraction vessels and three combined concentration systems. This makes sure that the quality is always the same and that the goods are delivered quickly, usually within 5 to 8 working days. With 100 tons in stock and open OEM/ODM services, we can give our partners in the pharmaceutical and nutraceutical industries a steady supply of this important neuronal membrane precursor that can be tracked. Our product is different from other choline sources because it contains both choline and cytidine. This means that it can successfully cross the blood-brain barrier to help with brain health and cognitive function.
The substance, which is called Cytidine 5'-diphosphocholine sodium salt (CDP-Choline), is a very powerful naturally occurring chemical that is needed to make phosphatidylcholine, which is the main building block of neuronal membranes. This complicated molecule solves important problems in brain health formulas.
You'll like how it works with two mechanisms in your product creation. It gives choline for making acetylcholine and cytidine for fixing neural membranes at the same time. This makes it better than other choline supplements that only have one ingredient.
The sodium salt form makes it much more stable and soluble in water. This change makes the substance more bioavailable and easier for the body to absorb. You're working with a compound that was engineered to work well in biologically complex settings where other choline sources often fail when you use our ingredient.

Better Stability and Bioavailability
For your recipe problems, you need ingredients that always work. The way the product works is very similar to how phosphatidylcholine works, but it has been used in more advanced formulations for a longer time. It is easier for water to dissolve in sodium salts because their structure keeps pH levels stable.
Because of this, it works great for parenteral injections, liquid nootropics with a high concentration, and complex supplement blends. When you pasteurize this choline salt, it won't precipitate or break down like regular choline salts do.
Improved Brain Function
When you add this ingredient, you're giving your brain measurable benefits. It makes the brain's blood flow and metabolism better by making brain cells use more oxygen. This helps with cognitive loss with age and recovery after a stroke, which are two big needs in the market.
The compound works well to cross the blood-brain barrier and support the brain's structure and function. The neuroprotective properties of your finished goods will make them stand out.
Neuronal Protection and Repair
Neuroprotection and repair abilities are very important for pharmaceutical uses. When given within 24 hours of the start of a stroke, it stabilizes cell membranes during acute ischemic events and lowers the size of the infarct.
It can be used to treat TBI and help people regain their awareness because of this. These same processes help keep the brain healthy and help you remember things over time in nutraceutical formulations.
Pharmaceutical Solutions for Injections and IVs
Our Citicoline Sodium can be used as the main active drug ingredient in neuroprotective shots. The high solubility and low endotoxin levels meet strict safety guidelines for intravenous formulations used in stroke recovery.
In hospitals, accurate osmolarity estimates are needed. Our consistently pure material makes sure that dose works well in critical care settings.
Better Nootropic Supplements
In the market for brain enhancement, stability during production is a must. Our ingredient works well with high-end capsules and stacked nootropic powders that help with memory and focus.
When mixed with hygroscopic adaptogens and B-vitamins, the sodium form stays stable. You won't have problems with moisture absorption and clumping, which shorten the shelf life of products.
Functional Liquid Nutrition
The neutral organoleptic properties are very important for medical nutrition drinks and brain development formulas for kids. Our material dissolves totally without any solids forming, and it stays stable even after being heated.
This lets you make "clean-label" products with clear ingredient lists that medical workers and health-conscious consumers will both like.
Ophthalmic Neuroprotection
New research backs up applications in treating glaucoma. The chemical keeps retinal ganglion cells and optic nerve fibres safe. This gives you great chances to make your eye health products stand out if you're making specialized formulas.

Our facility is GMP, ISO 9001, ISO 22000, and FSSC 22000 approved, so you can be sure that every batch meets pharmaceutical standards. For strict quality control, we use high-tech testing tools like HPLC, GC, and UV-Vis spectrophotometry.
We support testing by a third-party lab, and we offer free samples before shipping. This lets you check the quality of the material before committing to large production runs.
From finding the raw materials to the final packaging, our integrated supply chain makes it possible to track everything. We never have shortages of up to 100 tons, so your product sales won't be held up by them.
You can act quickly on market opportunities when you have production lead times of 7–15 days for custom needs. For items that are already in stock, delivery happens seven days after payment is confirmed.

Xi'an DN Biology has been working with botanical extracts for more than ten years and has the most up-to-date production equipment. They are available 24 hours a day, seven days a week, and our skilled export team knows how important it is for you to meet your deadlines.
To make foreign buying easier, we offer DDP shipping services and other transportation options. OEM/ODM customization is possible based on your exact formulas and needs, and the factory can be inspected on-site to back this up.
Our product gives your brand the quality and consistency it needs, whether you're making pharmaceutical treatments, premium nootropics, or functional nutrition products.
Q: What's the difference between sodium citicoline and citicoline?
A: Converting citicoline into its sodium salt form is standard pharmaceutical practice. This enhances molecular stability and improves water solubility, facilitating better absorption and utilization in your formulations. The sodium form is particularly advantageous for injectable and liquid applications.
Q: What are the proper storage conditions?
A: Store the product in a sealed, light-protected container in a cool, dry environment. This prevents moisture uptake and maintains potency throughout the shelf life. Proper storage ensures consistent performance in your finished products.
Q: What about acidity and solution clarity?
A: After dissolving, the pH of the aqueous solution ranges between 6.0 and 7.5, nearly neutral. The solution must be clear and colorless. These properties make formulation straightforward and ensure compatibility with sensitive biological delivery systems.
