The present invention relates to fast dissolving
powder combinations or compositions of high molecular weight
hyaluronic acid (HMW-HA) and to processes for preparing HMW-HA water-based fluid compositions comprising them such as a drinkable composition, e.g., a
ready to drink (RTD) beverage or another water-based fluid product for oral use containing HMW-HA, or water-based HMW-HA spray product for topical use. The drinkable HMW-HA water-based fluid compositions, for example a RTD beverage of HMW-HA, obtained using the fast-dissolving
solid combinations or compositions of the invention are useful for, but not limited to, joint health,
skin care, anti-aging. The fast-dissolving
solid combinations or compositions of high molecular weight
hyaluronic acid (HMW-HA) of the present invention can also be advantageously used for the preparation of a water-based HMW-HA spray product (e.g., a mouth spray, a
topical spray for the
skin or joints, a
lung spray).
