Explore our core bulk portfolio, engineered for sports nutrition, functional food, and dietary supplement formulations.
An authoritative analysis for procurement officers, chemical engineers, and formulation scientists.
Potassium Citrate (Tripotassium Citrate, Monohydrate CAS 6100-05-6 / Anhydrous CAS 866-84-2) is a vital organic potassium salt of citric acid ($K_3C_6H_5O_7 \cdot H_2O$). As global food manufacturers, pharmaceutical formulators, and sports beverage developers face stringent mandates for sodium reduction and systemic electrolyte replenishment, Potassium Citrate has emerged as the premier functional alkalizer, buffering agent, and bioavailable mineral compound.
As a specialized OEM/ODM Potassium Citrate exporter and contract manufacturing leader, Sunland Nutrition Inc leverages over 13 years of validated chemical synthesis, advanced multi-stage vacuum crystallization, and certified cleanroom processing to provide pharmaceutical grade (USP43 / EP10), food grade (FCC XII / E332), and direct compression (DC grade) Potassium Citrate powders to global markets.

Navigating regulatory shifts, low-sodium food reformulation, and supply chain security.
With public health authorities worldwide instituting strict limits on dietary sodium, food processors are replacing Sodium Citrate ($Na_3C_6H_5O_7$) with Potassium Citrate. It delivers equivalent ionic strength and pH buffering without elevating blood pressure markers, driving a predicted 7.4% CAGR in B2B demand.
The global surge in sports hydration stickpacks, zero-sugar isotonic RTD beverages, and keto-friendly electrolyte premixes requires ultra-soluble, clean-tasting Potassium Citrate. Manufacturers demand instant dissolution without saline or bitter off-notes.
Global brand owners prioritize contract manufacturers offering end-to-end supply chain transparency, carbon-neutral fermentation routes for citric acid substrates, and dual-region warehouse buffers (US warehouse domestic release + Asian mill direct supply).
Procurement teams are moving away from spot-market commodity buying toward strategic contracts with integrated OEM/ODM partners. In an era marked by ocean freight fluctuations and stringent cGMP audit standards, partnering with a vendor capable of managing dual warehousing (such as Sunland Nutrition’s California inventory hub paired with mill-direct volume contracts) reduces stock-out risk by up to 92%.
Overcoming caking, dust control, and compressibility limitations in potassium citrate production.
Potassium Citrate monohydrate is inherently hygroscopic. Under humidity conditions exceeding 60% RH, traditional crystalline powders tend to form agglomerates and cake inside industrial hoppers, causing severe downtime during high-speed tableting or stickpack filling operations.
To solve hopper caking and poor flowability, our OEM manufacturing facilities utilize fluid-bed spray drying to produce spherical, direct-compression (DC grade) Potassium Citrate granules. This process increases bulk density from $0.75 g/cm^3$ to $0.98 g/cm^3$, improving compressibility and tablet hardness in direct compression formulas by over 40%.
Utilizing dynamic multi-stage membrane filtration and ion-exchange columns during liquid-phase neutralization of potassium hydroxide with citric acid, our process eliminates heavy metals down to sub-ppm levels (Lead < 0.5 ppm, Cadmium < 0.1 ppm, Mercury < 0.1 ppm). This guarantees total compliance with strict EU Regulation (EU) 2023/915 and US California Proposition 65 limits.
Unmatched quality control, full documentation suites, and agile contract manufacturing from California, USA.
Founded in 2012 in Aliso Viejo, California, Sunland Nutrition Inc has established itself as an industry-trusted raw ingredient exporter and custom solution provider for nutraceutical, beverage, and pharmaceutical enterprises across North America, Europe, Latin America, and the Asia-Pacific region.
Every single bulk shipment is accompanied by a batch-specific Certificate of Analysis (COA), Technical Data Sheet (TDS), Safety Data Sheet (SDS), Allergen Statement, Non-GMO declaration, and residual solvent reports. NOP USDA Organic, Kosher, and Halal certificates are verified per lot.
We maintain deep stock positions at our main US warehouse facilities in California. Orders for core grades ship within 1–3 business days, while full container load (FCL) direct-from-mill programs run seamlessly with tailored 4–8 week production schedules.
From custom particle size milling (20 mesh coarse granules down to 320 mesh micro-powders) to custom mineral/vitamin premixes, private label 25kg paper bags, fiber drums, 1000kg super sacks, and retail-ready stickpack sachets—we deliver end-to-end contract manufacturing.
Addressing core technical, regulatory, and logistics queries from global purchasing managers.
Potassium Citrate Monohydrate ($K_3C_6H_5O_7 \cdot H_2O$, CAS 6100-05-6) contains one molecule of water of crystallization (~5.5% moisture content) and is the standard form used in food, beverages, and pharmaceuticals due to its chemical stability. Anhydrous Potassium Citrate ($K_3C_6H_5O_7$, CAS 866-84-2) has had its water of crystallization removed, making it extremely hygroscopic. Anhydrous is strictly specified for moisture-sensitive dry formulations, effervescent tablets, or non-aqueous chemical synthesis.
To ensure free-flowing characteristics upon destination arrival, our Potassium Citrate bulk bags feature dual-layer high-barrier polyethylene liners vacuum-sealed inside multi-wall kraft paper bags or moisture-proof fiber drums. For high-humidity destination routes, we supply spray-granulated (DC grade) or custom anti-caking coated options (using silica or food-grade silicates at <0.5% level upon client request).
We provide a complete regulatory packet suitable for FDA, EFSA, and Health Canada audits. This includes batch-specific Certificate of Analysis (COA), cGMP compliance proof, Manufacturing Process Flow Charts, BSE/TSE-Free Certificates, Heavy Metal & Arsenic ICP-MS Reports, Pesticide Residue Screens, Allergen Statements, Kosher & Halal Certificates, and ISO 22000 / FSSC 22000 plant audit summaries.
For standard US warehouse inventory, our MOQ starts at 25 kg (single drum/bag) for pilot trials and formula development. Direct export FCL container orders typically start at 1,000 kg (1 MT) up to 25,000 kg (25 MT full container loads). We supply complimentary 200g–500g laboratory evaluation samples with matching COA to qualified R&D teams worldwide within 3–5 business days.
Yes. Our cleanroom blending facilities allow us to produce custom homogenous premixes combining Potassium Citrate with Magnesium Glycinate, Calcium Citrate, Sodium Chloride, Zinc Citrate, Vitamin C, and natural flavor/sweetener systems (such as Organic Allulose, Monk Fruit, or Stevia Reb-A). We offer full private-label contract packaging in custom bulk bags or retail stickpacks.
