Bioactive Collagen HP-BCP Special Pets

The most effective form of collagen for joints adapted to dogs digestive system

Collagen HP-BCP is the best known form of collagen for joint health and it has been extensively studied in different clinical trials. Because dogs digestive system differs from humans, specific adjustments were made to ensure a high rate of absorption at the gut level. HP-BCP Pets is proven to enhance the joint renewal metabolism and stimulate the growth of new cartilage tissue in dogs. HP-BCP Pets is well absorbed and it concentrates in the joints where it has a significant impact on specific cells within the cartilage that are responsible for regularly producing new cartilage components. These cells, called chondrocytes, will increase their synthesis of collagen and proteoglycans, which together represent 95% of the cartilage structure.

Knee Cartilage Histological Section

A study by the Collagen Research Institute in Kiel, Germany, showed that HP-BCP accumulates in joint tissue and stimulates cell biosynthesis to produce collagen and proteoglycans. After 3 months of therapy, a significant change in formerly degraded cartilage is visible. Compared to joint cartilage with no treatment (left side), the joint cartilage appears supple, smooth and full in appearance.

Magnetic Resonance Imaging

The study conducted at Tufts Medical Center and Harvard Medical School and presented at the OARSI congress (Osteoarthritis Research Society International) showed that oral intake of HP-BCP provides clear improvement in human cartilage, for the first time measured using MRI (Magnetic Resonance Imaging) technology.

Hyaluronic Acid Complex HJ

Restoring and maintaining quality synovial fluid

articular synovial fluid

To perform well, joints need lubrication and this is why there is a thick viscoelastic substance called the synovial fluid inside the joint capsule. What confers this fluid its remarkable properties is Hyaluronic Acid (HA), a molecule that has the ability to hold up 1000 times its weight in water. HA forms large viscoelastic gels that reduce friction between cartilage surfaces and protects them.

Arthritic joints have a much lower concentration of HA than normal joints and restoring adequate HA levels is an important part of joint health. The Hyaluronic Complex HJ is a unique patented natural ingredient with a high content of sodium hyaluronate as a mix of High/Very High molecular weight Hyaluronic Acid. HA is the chief component of synovial fluid and its usefulness has been proven in numerous clinical trials.

Low Molecular Weight Hyaluronic Acid (LMW-HA) is sometimes touted as a better HA because it allows for a better intestinal absorption. But scientific evidence shows that HA is only safe and beneficial in its High Molecular Weight form (HMW-HA). Research has revealed that LMW-HA can be harmful as it promotes inflammation and has other negative side effects. On the other hand HMW-HA is much more effective at retaining water and its rate of absorption is significant enough to accumulate in the joint cavity.

The uptake of high quality HA in the joints improves lubrication, reduces inflammation and slows down the degradation process. The cartilage is also better nourished, it helps the cartilage nenewal and it can significantly improve joint flexibility.


MSM (Methylsulfonylmethane)

Research has observed that the sulfur content of cartilage decreases with age, and that this decrease parallels degeneration in the joints. A study has clearly shown that arthritic joints have sulfur levels three times lower than healthy ones. Sulfur is necessary for making collagen, the primary constituent of cartilage and connective tissue.

MSM is a bioavailable natural form of organic sulfur found in all living organisms. It is exceptionally well tolerated and it is rated as one of the safest substances in biology. Sulfur is the third most abundant mineral in humans and mamalians, after calcium and phosphorous. There is a general assumption that sulfur requirement is met with adequate protein intake which provides the amino acids methionine and cysteine, but disfunctions in methionine metabolism could induce sulfur deficiencies.

MSM is very helpful for joint metabolism. Even severe cases of joint alteration can benefit from MSM supplementation as it is able to significantly improve chronic pain without any side effects. Aside from its anti-inflammatory action MSM can also stimulate the the immune system and improve the internal production of Glutathione, the body's major own antioxidant.


Eggshell Membrane NEM®

Eggshell Membrane NEM®is a food-sourced ingredient derived from the membrane of an eggshell. It supplies essential nutrients needed to support joint mobility and the healthy production of cartilage and connective tissue. It is a unique biological matrix proven bioavailable and effective.Double-blind, placebo-controlled and open-label trials have all showcased an increase in joint comfort, flexibility, and increased range of motion. Published human studies have shown beneficial results in 7-10 days.

After 30 days intake:

  • 72.5% improvement in general pain.

  • 43.7% improvement in flexion range of motion.

ESM appears to supply the building blocks in a pattern that stimulates the healing process for the joint and promote cartilage renewal.


Chondroitin sulfate LMW Pharmagrade & Glucosamine Hcl

Glucosamine and Chondroitin are the most popular substances and most widely used ingredients in joint health products. Clinical studies are numerous but results are unclear and differ widely. After years of research, it is still difficult to precisely assess their level of efficacy but they no longer appear to be silver bullets as once thought. Nonetheless they can be useful in assisting other active ingredients and help restore functionality faster. There is also data showing that these mucopolysaccharides support the healing process of injured tendons.

It is important to remember that Chondroitin in its basic form it is mostly useless since it is simply not absorbed. The benefits of Chondroitin Sulfate only concerns the pharmagrade CS, a highly purified and depolymerized substance. Conventional food grade chondroitin is a very large molecule that is not assimilated through the intestinal mucosa. The molecular weight of the Chondroitin used has a direct influence upon its level of efficacy. The properties of the low molecular weight Chondroitin do not apply to conventional Chondroitin (Biol. Pharm. bull. 27(1)47-51 - 2004).

Devil's Claw

Harpagophytum procumbens, known as Devil's Claw is traditionnally used for its benefits on the joints and concerns about rheumatic ailments. It relieves pain and inflammation and Its effectiveness is commonly attributed to its identified special active constituents, the "harpagosides". Several clinical trials have shown effectiveness in alleviating pain and it appears to prevent the production of pro-inflammatory cytokines. This result seems derived from its harpagosides content but also from the interaction of several substances contained in its root (1).

Devil's Claw appears to be effective for chronic pain with a notable improvement of symptoms that reaches peak efficacy after a period that ranges from 6 to 8 weeks (2) (3) (4), though some scientific sources cite a 4 months duration to reach maximal efficacy (5).


Organic Silica

Orthosilicic acid (non-crystalized silica)

Silicon is an essential trace mineral that is naturally present in the human body. It play a major role in bone strength, healthy skin and nails and cartilage formation. Studies have shown that a silicon deficient diet produces aberrant metabolism of the bone and connective tissue leading to structural abnormalities of the articular cartilage with small and poorly formed joints. It was later discovered that silicon deprivation decreases collagen formation in wound healing as well as bone formation.*

Silicon is widely available and abundant in nature but its bioavailability is very poor. It is an extremely unstable compound that crystalizes very quickly forming an insoluble inert substance. Its absorption is drastically low and it can’t be utilized by the human organism.

Calbrex™ contains a stable high absorption form of dietary silicon. It is an ortho-silicic acid molecule stabilized in maltodextrin. It is stabilized by a proprietary method that inhibits the polymerization of ortho-silicic acid, keeping the molecule stable and increasing its bioavailability in the body.



The ongoing studies conducted on the miracle spice from India keep confirming its usefulness for an ever wider range of health concerns. And Turmeric is also helpful for arthritis and other joint problems through its modulation of inflammatory signals in several different ways. Its active component, Curcumin, is able to prevent pro-inflammatory messaging, it can reduce the activity of pro-inflammatory enzymes and it can also downregulate the immune system over-reactivity on inflammation areas.

Clinical research on orally administrated curcumin has shown that it is equally or more potent than synthetic anti-inflammatory drugs when taken for several weeks and up to several months. The level of relief demonstrated is in the range of 40 - 60% reduction of symptoms of knee osteoarthritis on threadmill testing.
