Methods and compositions for reducing inflammation and preventing oxidative damage
Provided herein are nutraceutical compositions with antioxidant properties. Also provided are methods of using polysaccharides for applications such as reducing inflammation, providing oxidation in mammalian tissue, and other uses. Also provided are algae capable of incorporating exogenously provided monosaccharides into polysaccharides synthesized in vivo to aid in antioxidant activity.

26 . A method of producing a nutraceutical composition comprising:
a. culturing red microalgae;
b. separating the microalgae from culture media; and
c. disrupting the microalgae to produce a homogenate.
27 . (canceled)
28 . The method of claim 26 , further comprising formulating the homogenate with a carrier suitable for human consumption.
29 . The method of claim 28 , wherein the carrier is a plant or animal product.
30 . The method of claim 28 , further comprising formulating the homogenate with a carrier suitable for human oral consumption as a tablet.
31 . (canceled)
32 . The method of claim 26 , wherein the disruption is performed by a method selected from the group consisting of pressure disruption, sonication, jet milling and ball milling.
