About OxC-beta

Avivagen's proprietary and patent-protected technology is based on its discoveries concerning carotenoid antioxidants. The novel natural compounds discovered by Avivagen support the body's own systems to maintain and enhance health, particularly by supporting immune function. Avivagen's commercial-stage application of its technology is Fully-Oxidized beta-Carotene (OxC-beta).

OxC-beta compounds occur naturally as carotenoid oxidation products in vegetation, but in minute amounts. They have been developed to support the health of companion animals and for use in the global food animal market.

Research results indicate OxC-beta supports innate immune function, which can help maintain good health. In pets, OxC-beta supports overall vitality and energy, mobility and joint function, skin, coat and gut. Results observed in food animals have included healthier growth, better utilization of feed and decreased mortality. In food animals, it is intended that use of OxC-beta avoids the feeding of antibiotics.

The commercial products of Avivagen are Oximunol(TM) Chewables, OxC-beta for livestock and Vivamune(TM) Health Chews.
