  • Publication number: 20090092709
    Abstract: The present invention provides a dietary supplement, and method for making the same, comprising a glucosamine-based beverage that has the physical appearance of water, or that otherwise appears substantially transparent in its final form. The method for making the glucosamine-based beverage includes passing an aqueous glucosamine-containing solution through a multiple-step filtration process at a predetermined pH level. The first filtration step is performed with a porous volumetric fiber matrix, which is a Nominal rated filter with a cut off in the range of 0.5-1.2 microns, and preferably 0.5 microns, and at a cross-filter pressure less than or equal to 10 psi. The second filtration step is performed with a membrane filter, which is an Absolute rated filter with a cut off in the range 0.3-0.6 microns, and preferably 0.45 microns, and at a cross-filter pressure less than or equal to 10 psi.
