Why do large dogs require extra joint care?
Large and giant breed dogs grow rapidly and carry significant body weight. This places constant, heavy pressure on their musculoskeletal system.
Over time, this can lead to:
- micro-damage and loss of joint cartilage,
- reduced production of synovial fluid,
- limited joint mobility.
Studies show that osteoarthritis may affect up to 80% of dogs over the age of 8. That is why proactive joint support is essential – ideally starting before the first signs of stiffness or discomfort appear.
ASU – next-generation joint support
ASU-flex® ADVANCED goes beyond standard supplements. At the heart of our formula is ASU (Avocado Soybean Unsaponifiables) – natural extracts from avocado and soybean oils that support the physiological function of the joints.
Research indicates that ASU can:*
- support cartilage metabolism
- boost the production of proteoglycans (essential building blocks of the cartilage matrix)
- stimulate the synthesis of type II collagen
- help limit cartilage breakdown
- reduce the production of pro-inflammatory substances
- significantly improve the quality of life for dogs experiencing joint discomfort
What’s inside ASU-flex® ADVANCED ?
Our breakthrough formula combines 7 key ingredients for total joint health:
- ASU (Avocado Soybean Unsaponifiables) – protects cartilage and supports the slowing of degenerative processes
- native type II collagen – makes up to 96% of collagen in cartilage tissue
- crystalline glucosamine – features 3.5x higher bioavailability than standard glucosamine for superior absorption
- chondroitin – supports joint flexibility and cartilage density
- hyaluronic acid – a key component of synovial fluid; reduces friction and ensures smooth movement
- type II collagen hydrolysate – provides essential building blocks for joint repair
- vitamin E – a powerful antioxidant that protects joint cells from oxidative stress
