The present invention relates to the field of nutraceuticals, and in particular to nutraceuticals comprising sulfated polysaccharides, Astragalus polysaccharides, resveratrol, and combinations thereof. These compositions find use in inducing physiological responses such, decreasing body fat, increasing lean body mass, alleviating the symptoms of colds, preventing the onset of colds, increasing energy, increasing the feeling of well-being in subjects, and improving skin tone and appearance.

Disclosed are intra-articular compositions comprising at least one low-molecular-weight linear hyaluronic acid or hyaluronate and at least one high-molecular-weight linear hyaluronic acid or hyaluronate, said compositions being characterised by a dynamic viscosity ranging between 10 and 60 Pa*s (at 0.01 s.sup.-1), a crossover frequency ranging between 1 and 10 rad/s, and a value of the viscous and elastic moduli at the crossover frequency ranging between 20 and 110 Pa.

Provided are pharmaceutical compositions comprising a sulphated polysaccharide and a shear-thinning fluid gel. The sulphated polysaccharide may, by way of example, be selected from the group consisting of: a dextran sulphate having an average molecular weight of 10,000 Da or less; heparan sulphate; fucoidan; poligeenan; furcellaran; and a carrageenan. The shear-thinning fluid gel may comprise a microgel particle forming polymer, suitably selected from one or more of the following groups: gellans; alginates; carrageenans; agarose; chitosan; pectin; agarose; agar or gelatin. The compositions disclosed may be used for the prevention and/or treatment of glaucoma. These compositions may be used for the inhibition or reduction of fibrosis. The invention also relates to the medical uses of sulphated polysaccharides, and the medical uses of shear-thinning fluid gels.
