We offer tripotassium citrate monohydrate powder-a high-quality potassium supplement and alkalizing agent where potassium ions exist stably in the form of an organic acid salt, using citrate as a carrier.
Regarding potassium supplement selection: While potassium chloride is inexpensive and highly effective, it has a salty and astringent taste and can irritate the gastric mucosa; potassium citrate, although palatable, may pose a metabolic burden due to its alkaline load for some individuals. Tripotassium citrate offers a third approach-it combines three potassium ions with citrate, providing the highest potassium content per unit mass. Furthermore, citrate, as a core intermediate metabolite in the tricarboxylic acid cycle, exhibits excellent biocompatibility and does not impose an additional burden on acid-base balance.
Through strict purity control, comprehensive testing for heavy metals and microorganisms, and superior solubility and anti-caking process control, we have solved the three core pain points of traditional potassium supplements: poor taste, high alkaline load, and limited solubility, making potassium supplementation truly efficient, tolerable, and easily compatible.

Benefits of Tripotassium citrate monohydrate powder
Supports normal neuromuscular function: Potassium ions participate in nerve impulse transmission and muscle function.
Supports electrolyte balance: Potassium is the most abundant intracellular cation in the human body, participating in maintaining normal fluid balance and osmotic pressure.
Also provides citrate: Citrate ions are metabolized in the body to produce bicarbonate, which helps maintain the body's acid-base balance.
Helps maintain normal blood pressure levels: Potassium plays a role in blood pressure regulation by promoting sodium excretion and vasodilation.
Supports normal heart rhythm function: Potassium ions participate in the electrical activity of myocardial cells, supporting the maintenance of a normal heart rhythm.

Production Process
Product Quality Advantages
Neutralizes All Three Carboxylic Groups: Fully tribasic salt provides maximum alkalinity and buffering capacity among all potassium citrates, ideal for pH stabilization in liquid formulations.
Monohydrate Crystal Stability: Bound water (4.0%–7.0%) prevents excessive hygroscopicity and caking during storage, unlike anhydrous tripotassium citrate which rapidly absorbs moisture.
Low Oxalate Content: Oxalate controlled to ≤0.03%, making it suitable for applications where oxalate intake is a consideration.
Dual Function as Potassium Source & Citrate Donor: Provides both potassium ions and citrate anions from a single ingredient, simplifying formulation of electrolyte blends and buffered systems.
Direct Compressibility: Fine crystalline structure supports direct compression in tablet manufacturing without extensive granulation steps.
Low Carbonate Residual: Alkalinity (as K₂CO₃) controlled to ≤1.0%, minimizing unwanted carbonate content that could affect formulation pH.

FAQ
Q: Why is the monohydrate form preferred over the anhydrous form?
A: The monohydrate form contains a consistent amount of water (4.0%–7.0%), providing predictable stoichiometry and stable physical properties. Anhydrous tripotassium citrate is highly hygroscopic and may absorb moisture from the air, leading to caking and weight variability. The monohydrate form is more stable under normal storage conditions.
Q: Is Tripotassium citrate monohydrate powder suitable for clear liquid applications?
A: Yes. Tripotassium citrate is freely soluble in water and produces clear solutions, suitable for fortified waters, electrolyte drinks, liquid supplements, and oral rehydration solutions.
Q: Is tripotassium citrate safe for use in food?
A: Yes. Tripotassium citrate is GRAS (Generally Recognized as Safe) by the US FDA and approved as food additive E332 in the EU. It has a long history of safe use in foods and beverages .
Q: What is the shelf life and how should it be stored?
A: Shelf life is 24 months when stored properly. Store in sealed containers in a cool, dry place below 25°C, relative humidity ≤60%, protected from moisture and light .
Q: Is it suitable for low-sodium products?
A: Yes. Tripotassium citrate contains sodium levels typically ≤0.3%, making it an excellent potassium-based alternative to sodium salts in low-sodium formulations .
