Complete Joint Blend with Hyaluronic Acid, Collagen & MSM

When performance animals are working hard, pushing limits, facing thick cover or extreme terrain, ordinary joint support isn’t enough. Ultra Flex Herbal Joint & Pain Response Supplement from Elite Nutrition is built for the elite athlete: larger size, greater demands, higher recovery demands. Formulated for equine performance use—designed to help serious athletes rebound from soreness, inflammation and joint stress. For more detailed application or multi-animal use, please call us at 757-482-1000 or email us.

Ultra Flex takes everything the Endura Flex Plus delivers and adds advanced pain-response support and heavy-duty recovery aids. With the inclusion of white willow bark for a natural pain response, a proprietary enzyme blend to help rapidly recover from over­activity, and extra hyaluronic acid & collagen peptides for joint lubrication and connective tissue support—this is the next‐level formula for performance animals in the field.

Key Benefits

• Enhanced Pain Response: White willow bark supports a healthy pain-response pathway naturally—ideal for large athletes under load.
• Performance Recovery Enzyme Blend: A special blend of protease, papain, bromelain, amylase, lipase and more helps accelerate recovery from soreness, inflammation and high-impact work. :contentReference

Ideal For

• Performance horses, field trial equine, pack animals logging heavy miles
• Animals recovering from intense work, high-impact terrain, extended runs or hunts
• Situations where joint stress, soreness or overuse demand more than basic maintenance support
• Facilities or handlers who demand advanced support and are willing to invest in premium recovery tools

Why We Recommend It

At Outdoor Dog Supply, we understand gear and support matter for the athlete below the collar—whether that’s a horse or field companion hauling miles day in and day out. Ultra Flex delivers serious recovery, performance-grade joint & pain support, and return-to-performance readiness when the terrain and work demand more. It’s the formula we reach for when “regular” isn’t enough.
