US Clinicals® StrongJoint™ Sports

$63.75 $75.00

StrongJoint™ Sports Advanced Joint Restoration Complex is designed with Collagen Type II, Serratia E-15, and L-Arginine to improve athletic performance & endurance and promote optimal joint health for those regularly engaged in sports activities.

L-Arginine is a breakthrough ingredient based on a Nobel Prize-Winning Discovery. It helps to maximize the body’s production of Nitric Oxide (NO), thereby increasing oxygen supply for improved sports efficiency and performance.

Serratia E-15, an enzyme with strong anti-inflammatory and fibrinolytic properties, is proven to support recovery after sports such as muscle pull & tear.

Collagen Type II
Collagen Type II is a natural protein that helps to protect our tendons and ligaments during intense exercises, as well as promoting faster recovery of the joints’ connective tissues. Studies show that Collagen Type II has multiple protective benefits to our joints. It helps to:

  1. Resist cartilage protein digesting enzymes
  2. Reprogram destructive chondrocytes to lessen inflammation
  3. Promote new cartilage and proteoglycan synthesis
  4. Enhance the production of Hyaluronic Acid (HA), producing a thick, effective & lubricating synovial fluid that protects and cushions joints
  5. Protect the surface of cartilage from oxidative (free radical) damage and enzymatic digestion
  6. Act as a powerful anti-inflammatory/pain modulator which is extremely helpful for sports persons


L-Arginine is an amino acid present in our body, necessary for the production of Nitric Oxide (NO). NO helps to improve blood flow in the arteries and effectively prevent coronary heart disease. L-Arginine plays a critical role in the body by increasing the blood vessels’ elasticity and flexibility. Studies have shown that NO can help to improve one’s vasodilation and blood pressure, which improves immunity, exercise efficiency, sports performance and endurance level.

Veggie Glucosamine Sulfate

Glucosamine Sulfate is a compound found naturally in the cartilage matrix and synovial fluid. It acts like a lubricant to keep the joints moving smoothly. Studies show that supplementing Glucosamine Sulfate will reduce the rate of collagen (joint tissue) degradation and symptoms of osteoarthritis. Daily consumption of Glucosamine Sulfate can help to repair damaged cartilage and slow down joint degradation, which is extremely important for athletes involved in high impact sport activities.

OptiMSM® (also known as methylsulfonylmethane) is a natural form of organic sulfur found in the body that can help to support flexibility and strength in the body’s connective tissues and cell membranes. MSM has also been widely used for the relief of inflammation, stiffness and swelling from arthritis. Studies show that OptiMSM® is effective in fighting against Osteoarthritis and other joint conditions due to its ability to reduce oxidative stress and pain associated with physical training.
