  • Procosa is formulated with Meriva, an innovative curcumin phytosome that has been shown to deliver noticeable improvements in joint comfort and mobility in as little as 90 days.
  • A study co-authored by USANA scientists and published in the Journal of Natural Products  revealed Meriva delivers a significant improvement in bioavailability compared to traditional curcumin (from turmeric) extracts.

Nearly one in three adults in the United States suffers from some form of joint problem. The situation is worse for athletes and those who are subject to high amounts of physical stress at work and at home. To help support healthy joints, USANA created Procosa supplement, a product with a blend of glucosamine, manganese, vitamin C, and silicon—building blocks for healthy cartilage.*

Cartilage is the protective layer that cushions and lubricates the joints. Over the years, the cartilage in our joints is gradually worn down due to normal physical activity. The body rebuilds the cartilage as it is worn and replaces shock-absorbing synovial fluid, so the joints are always protected. For various reasons, however, the production of new cartilage and synovial fluid can fall behind demand. Because of poor blood supply, lesions to articular cartilage do not heal at the same rate as in other tissue in the body; cartilage is rebuilt slowly. If components of the substances used for cartilage repair are in short supply, recovery from damage can be slowed even more.

Glucosamine, an amino sugar, is an important precursor in the biosynthesis of cartilage. Specifically, it is a building block of proteoglycans—-protein molecules with a high content of bound carbohydrates. Proteoglycans and collagen compose the majority of the cartilage matrix. Proteoglycans are essential for healthy cartilage because they bind the water that lubricates and cushions the joint.*

In addition to its role as a biochemical precursor, glucosamine is believed to play a role in regulating cartilage formation and normalizing cartilage metabolism by encouraging higher production of collagen and proteoglycans. Glucosamine also stimulates synovial production of hyaluronic acid, which is responsible for the lubricating and shock-absorbing properties of synovial fluid.*

Numerous double-blind clinical studies have shown the efficacy of glucosamine supplements in maintaining healthy cartilage, healthy joints, and full range of motion in the short-term. More recently, a three-year study was published showing that joint space increased in the glucosamine-treated group, while it continued to decrease in the placebo group, indicating that the protective cartilage was better maintained in those who used glucosamine. Additional studies have demonstrated that glucosamine, taken orally, is well-absorbed and diffuses into tissues, including the articular cartilage.*

The combination of glucosamine with Meriva®† bioavailable curcumin complex, vitamin C, manganese, and additional joint-supporting nutrients represents a more comprehensive approach to joint health. Over the long term, these ingredients help retain healthy cartilage. Clinical studies have shown that Meriva bioavailable curcumin complex provides significant benefits for joint function. Manganese is required for enzymes involved in the biosynthesis of proteoglycans. Vitamin C is essential for the reactions necessary to
collagen formation.*


You can mess with your family, your neighbors, and maybe even your boss, but one thing is for sure—you can’t mess with your joints. Active adults and athletes all agree that joint problems can be an unforgiving and formidable foe that can cause you problems throughout your life. However, you’re not helpless—adding glucosamine to your diet may help maintain healthy cartilage and joints. Procosa is not only an excellent source of glucosamine, it’s formulated with vitamin C, manganese, and other important nutrients essential for optimal joint health.* Another advantage of Procosa is that it contains the Meriva bioavailable curcumin complex, enhancing the supplement’s action to provide more noticeable benefits. Vitamin C and Meriva also help neutralize cell-damaging oxidative stress.* Procosa is a great way to start taking care of your joints so you can keep doing the things you love.*
