Osteo Bi-Flex® helps renew cartilage, lubricate joints and support range of motion over time. As we age, the body is less able to renew and maintain the supportive cartilage structures surrounding joints and bones. Occasional stiffness and achiness, especially on waking, may be signs that your joints need extra supplementation. Osteo Bi-Flex® can help provide your body with the valuable nutrients that lubricate and help cushion your cartilage and joints. Plus Osteo Bi-Flex is the only leading brand with 5-LOXIN®. Taking 5-LOXIN® shows improvement in Joint Comfort within 7 days.
