Hyaluronic Acid (Sodium Hyaluronate) Powder for Joint-Comfort, Hydration and Skin-Beauty Supplement Formulas

Hyaluronic Acid Overview

Hyaluronic acid, also called hyaluronan or hyaluronate, is a naturally occurring, non-sulfated glycosaminoglycan made of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine. In the human body it is a structural component of synovial fluid, cartilage, skin and connective tissue, where it binds water and supports tissue hydration and lubrication. For dietary supplements, hyaluronic acid is normally supplied as sodium hyaluronate, the stable, freely water-soluble sodium salt form with CAS 9067-32-7 and repeating formula (C14H20NNaO11)n.

Purecium supplies food-grade sodium hyaluronate as a B2B raw material for distributors, contract manufacturers, private-label producers and finished supplement brands. Because hyaluronic acid is a polymer rather than a single small molecule, its commercial identity is defined by three parameters: the salt form, the assay of hyaluronic acid on a dry basis, and the molecular-weight grade, each of which is confirmed on the batch Certificate of Analysis.

Source & Ingredient Identity

Purecium Hyaluronic Acid is produced by submerged bacterial fermentation of a non-GMO Streptococcus zooepidemicus strain on glucose-based media, followed by cell separation, purification, alcohol precipitation and drying. Fermentation has been the industrial standard for food and supplement grades for decades because it delivers consistent, animal-free material; historical animal-tissue extraction routes are not used for food-grade supply. The product is vegan, allergen-free and gluten-free.

The declared product is sodium hyaluronate, CAS 9067-32-7, with the repeating unit formula (C14H20NNaO11)n and a repeat-unit molecular weight of approximately 401.3 g/mol; the corresponding acid form, hyaluronic acid itself, carries CAS 9004-61-9 and formula (C14H21NO11)n. Molecular weight is controlled by fermentation conditions and downstream enzymatic or shear-mediated processing, giving buyers a choice of oligo (below 10 kDa), low-molecular-weight, medium-molecular-weight and high-molecular-weight grades up to about 2.0 MDa.

Key Characteristics of Hyaluronic Acid

1. Exceptional water binding and solubility. Sodium hyaluronate dissolves readily in water to form clear, viscous solutions, and hyaluronan is documented to bind a large multiple of its own weight in water. This hydration capacity is the property behind its roles in synovial-fluid lubrication, skin moisture retention and tissue space filling, and it is the reason the ingredient is used in both oral and topical formats.

2. Defined by assay and molecular-weight grade. Food-grade sodium hyaluronate is specified by hyaluronic-acid content of at least 95% on a dry basis (measured via glucuronic-acid assay) and by molecular-weight window. Low-molecular-weight and oligo grades are the typical choices for oral supplements because smaller chains are more readily absorbed after ingestion, while high-molecular-weight grades form surface films suited to topical and dermal applications.

3. Clean, vegan and formulation-friendly profile. Because production is fermentation-based, the material is animal-free and suitable for vegan and vegetarian products, and it is non-GMO, allergen-free, gluten-free and non-irradiated. It is neutral in taste and odor, dissolves without haze, and is compatible with capsules, tablets, stick powders, gummies and functional beverages.

Hyaluronic Acid Manufacturing

The manufacturing route is controlled submerged fermentation: the selected Streptococcus zooepidemicus strain is grown under sterile, monitored conditions on glucose-based media, then the culture is inactivated and the hyaluronan is recovered by purification steps that remove cells, proteins and endotoxins, followed by alcohol precipitation, drying and milling to the target molecular-weight grade. In-process controls cover fermentation yield, broth viscosity, protein content and microbial purity at each stage.

Molecular-weight control is the defining step of hyaluronic-acid manufacturing. Downstream enzymatic or mechanical fragmentation tailors the polymer to the ordered grade, and each finished lot is tested for hyaluronic-acid assay by glucuronic-acid analysis, molecular weight, loss on drying, protein, pH of solution, heavy metals and microbial limits. Analytical practice follows the USP-NF and European Pharmacopoeia monograph approaches for hyaluronate sodium where applicable, and results are reported on the batch Certificate of Analysis.

Applications of Hyaluronic Acid

Joint-comfort and mobility formulas are the most established oral application. Hyaluronic acid is a natural component of synovial fluid and cartilage, and hyaluronic-acid supplements are commonly combined with glucosamine, chondroitin sulfate and MSM in joint-health products. Published clinical studies have used oral doses in the range of 100 to 240 mg per day in healthy adults, and finished-product communication in the United States follows the structure/function framework of the FDA.

Skin-hydration and inner-beauty supplements form the second major application cluster. Clinical research on ingested hyaluronan has examined skin moisture and appearance outcomes, and low-molecular-weight and oligo grades are the preferred forms for oral beauty powders, capsules and functional beverages. In the European Union no health claim for hyaluronic acid has been authorized to date under the EU nutrition and health claims regulation, so EU finished products use general food-information statements.

Because the salt is tasteless, colorless in solution and heat-stable under normal processing, formulators use it in stick-packs, effervescent and beverage formats as well as capsules and tablets. It also functions in functional-food and beauty-drink applications such as jellies and dairy-style products where EU novel-food authorization status, national approvals in China and Japan, and destination-market rules for the specific format must each be confirmed before launch.

Manufacturing & Quality Control

Purecium Hyaluronic Acid is produced in facilities operating under ISO 9001 and FSSC 22000 certified quality systems, with Kosher and Halal certification available. Every lot is tested for identity, hyaluronic-acid assay on a dry basis, molecular weight, loss on drying, protein content, pH, heavy metals (lead below 10 ppm), microbial limits and absence of pathogens, and pharmaceutical-grade monographs in the USP-NF and European Pharmacopoeia are referenced for analytical methods where applicable.

Regulatory recognition for hyaluronic acid includes FDA GRAS recognition for intended food uses, EFSA novel-food assessment for food-supplement use, and health-food ingredient approval in China and Japan. Each commercial lot is traceable from fermentation seed to finished drum, and Purecium provides the specification sheet, Certificate of Analysis, SDS, allergen and gluten statements, non-GMO declaration and stability data on request.

Hyaluronic Acid for B2B Supplement Manufacturing

Purecium supplies Hyaluronic Acid exclusively as a B2B raw material for distributors, contract manufacturers, private-label producers and finished supplement brands. The minimum order quantity is 25 kg, and the product is packed in 25 kg drums with food-grade polyethylene inner bags; samples and full documentation are available before commitment.

Molecular-weight grades are quoted against your target format: oligo and low-molecular-weight grades for oral beauty and joint formulas, and medium- or high-molecular-weight grades for dermal and specialty applications. For North American customers, inventory is staged at Purecium's US warehouse with delivery typically within about two days, and global shipping covers Hong Kong, mainland China, the EU and other regions with export documentation for every shipment.
