Hyaluronic Acid Ingredient Guide — Molecular Weight, Beauty & Joint
In shortHyaluronic acid (CAS 9004-61-9) is a polysaccharide used in beauty and joint supplements. High vs. low molecular weight changes the positioning and feel, and fermentation-derived food-grade material is mainstream.
What it is
Hyaluronic acid is a highly water-retaining polysaccharide formulated into supplements (beauty, joint) and beverages. Most is produced by microbial fermentation.
Differences by molecular weight
High molecular weight is more viscous; low molecular weight (hydrolyzed) is chosen for solubility/absorption positioning. Select the molecular-weight grade per product concept.
Sourcing points
Confirm molecular weight, purity, and source (fermentation). FONTIA offers hyaluronic acid; see functional ingredients.
FAQ
High or low molecular weight—which is better?
It depends on positioning. Low MW for absorption/solubility; high MW for viscosity/retention.
What is the source?
For food use, microbial fermentation is mainstream.
Can it be used in drinks?
Confirm molecular weight and solubility; low MW can be easier to handle.
