      Why Procosa?         

Procosa is USANA’s formula for joint health. We incorporate a full 2000 mg per day of high-quality glucosamine sulfate, a dosage significantly higher than the industry standard. Then we combine
this with turmeric extract, vitamin C, manganese, and silicon for comprehensive joint health.

• Vitamin C, manganese, and silicon provide additional nutrition essential for joint health Procosa  Difference
• Turmeric extract speeds the action of Procosa  to provide more immediate benefits

A Powerful Blend

The combination of glucosamine sulfate with turmeric extract, manganese, vitamin C, and silicon represents a more comprehensive approach to joint health. Over the long term, these ingredients help retain healthy cartilage. Turmeric contains curcumin and related compounds known as curcuminoids, which have good antioxidant properties. Manganese is required for enzymes involved in the biosynthesis of proteoglycans.

Vitamin C is essential for the reactions necessary to collagen formation. And silicon is required for proper
collagen formation and ultimately cartilage composition.

What Does Glucosamine Do?

  • Gives dramatic help for arthritic pain
  • Provides a natural alternative to aspirin and anti-inflammatory drugs
  • Stimulates repair in worn-out joints
  • Helps maintain normal joint function and resiliency

What Is Glucosamine?

Glucosamine is a natural molecule made by the body, composed of glucose and an amine (nitrogen and two molecules of hydrogen). Research shows that glucosamine plays a key role in helping to keep all the joints the body lubricated and supple.

It stimulates the manufacture of glycosaminoglyúcans, key structural components in cartilage which line the joints.Glucosamine also promotes the incorporation of sulfur into cartiúlage. Because of this effect, research shows that glucosamine sulfate is the most effective form.

The Glucosamine-Arthritis Connection

As people age, many lose their ability to manufacture sufficient amounts ofglucosamine.This may be the major factor leading to the degeneration of the joints, which causes painful joint movement and destruction of the joint’s cartilage.Glucosamine’s link to the joints led many researchers to wonder what would happen if those with painful joints took glucosamine.

The results were astonishing. Oral glucosamine (in the sulfate form) proved to be spectacular help for joint repair and rebuilding.

Degenerative Joint Disease

  • As the body ages, it may not produce a sufficient amount of glucosamine.
  • This can result in cartilage that loses its ability to act as a shock absorber in the joints.
  • The joints then become stiff and painful.
  • Every step or joint movement can be an agony.
  • This process is often diagnosed as degenerative joint disease, such as osteoarthritis, the most common form of arthritis.
  • The affected joints show gradual destruction of the joint’s cartilage followed by the formation of large, abnormal bone spurs in the joint margins.
  • The joints become very painful with limited range of motion and in time, they may become deformed.

Who Gets Joint Disease?

  • Over 40 million Americans have degenerative joint disease, including 80% of people over age 50.
  • Under age 45 degenerative joint disease is more common in men;
  • After age 45 it is ten times more common in women.
  • The weight-bearing joints, such as the hips and knees, as well as the joints of the hands are often the most affected.
  • How Does It Start?
  • The onset of degenerative joint disease can be very subtle.
  • The first symptom may be joint stiffness in the morning.
  • As the joint disease progresses, there is pain on motion of the affected joint that is made worse by prolonged activity and relieved by resting.
  • Inflammation is usually absent or minimal.

Joint Stress in Athletes   

Joint pain and injuries are one of the most common complaints in active people and athletes. Any type of active exercise places stress on joints. When the spine is out of alignment (called a subluxation), the nerves which pass between the individual vertebrae will have less room to carry nerve impulses, and eventually the nerve becomes impinged. This is the point where you feel pain and may go to see a chiropractor for an adjustment.

When injury occurs, the demand for collagen and other joint repair substances increases. Glucosamine is the rate-limiting factor in making many of these connective tissue and joint repair substances. If glucosamine stores are low, the joint repair compounds may not be able to be made.

Because of its joint repair benefits, glucosamine sulfate is a favorite nutritional supplement for those who are physically active.

Get the Best Form

Glucosamine comes in several forms:

  • glucosamine sulfate,
  • glucosamine hydrochloride and
  • N-acetyl-glucosamine (NAG)

Be careful in your selection of a glucosamine supplement:

the research showing the excellent joint-improving benefits was with glu-cosamine sulfate

Glucosamine hydrochloride performed poorly.

Some marketing companies have claimed that NAG is better absorbed and more stable, but scientific research does not support this. In fact, an unsuspected problem with NAG has been demonstrated: toxic brain effects.

For best results, use a nontoxic grade of glucosamine sulfate

Aspirin: A Gradual Killer

The first drug generally used to treat joint pain such as osteoarthritis is aspirin. Although aspirin can help relieve joint pain and inflammation temporarily in some cases, it often becomes toxic in therapeutic doses (2 to 4 grams per day). Early signs of aspirin toxicity are tinnitus (ringing in the ears) and stomach irritation. Long-term use of aspirin has been shown to cause the weakening of the walls of arteries and capillaries; many researchers believe this increased blood vessel fragility can help promote the onset of a stroke (breaking of a blood vessel in the brain) which may have disastrous consequences.

Straight To the Joints

Glucosamine is highly absorbed by the body.

Detailed pharmacoúkinetic studies in animals and humans show up to 98% of orally administered glucosamine sulfate is absorbed. These studies show that after absorption, glucosamine sulfate is preferentially taken up by the cartilage and other joint structures where it stimulates the body’s manufacture of chondroitin sulfate and other mucopolysacúcharides.

In human clinical studies, oral intake of glucosamine sulfate of 750 to 1,500 mg. per day showed the reversal process in osteoarthritis of the knee, verified by electron microscopy of biopsies.

One of the key effects of glucosamine sulfate is its ability to stimulate the incorporation of sulfur into cartilage.

Good News

Because of the awesome benefits of glucosamine sulfate in helping to stimulate joint repair and to maintain healthy joint function, this is good news for those suffering from joint pain (including osteoarthritis), spinal subluxation, cartilage degeneration, or joint injuries.

Glucosamine sulfate is an excellent choice to help prevent joint injury.
