The present invention is in the field of dietary supplements with a specific dosage of key nutrients to preserve and help with growth, and repair of joint connective tissue.
Treatment of joint pain depends on its cause and severity. Non-steroidal anti-inflammatory drugs (NSAIDs), steroids or even surgical intervention can solve the pain and limit further damage to the joints, but they all pose potential side effects and are almost ineffective for the promotion of joint tissue repair. Nutritional supplements can potentially help the joint health by stimulating the growth, repair and maintenance of bone and joint connective tissue.
One class of supplements includes components of joint connective tissue such as collagen, glucosamine, hyaluronic acid, and chondroitin. Other supplements act as catalysts or supply raw materials for bone and connective tissue synthesis these are mainly S-adenosylmethionine (SAM), methylsulfonylmethane (MSM), and other vitamins and minerals such as Vitamin C, manganese, magnesium, zinc, calcium, iron, and Vitamin B12.
Compositions containing glucosamine are known to be beneficial to both humans and animals that suffer from osteoarthritis pain. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis. Commonly sold forms of glucosamine are glucosamine sulfate and glucosamine hydrochloride. Glucosamine is often sold in combination with other supplements such as chondroitin sulfate and methylsulfonylmethane. Generally, vitamin C is needed together with glucosamine sulfate.
Chondroitin sulfate is a sulfated glycosaminoglycan (GAG) composed of a chain of alternating sugars (N-acetyl-galactosamine and glucuronic acid). It is usually found attached to proteins as part of a proteoglycan. Chondroitin sulfate is a major structural component of cartilage and provides much of its resistance to compression. Most of these supplements derive the Chondroitin Sulfate from bovine cartilage or velvet deer antler or shark cartilage. Avocado/soybean unsaponifiables (ASU) are natural vegetable extracts made from avocado and soybean oils, consisting of the leftover fraction (approximately 1%) that cannot be made into soap after saponification. ASU is composed of one third avocado and two thirds soybean unsaponifiables. The major components of ASU are phytosterols β-sitosterol, campesterol, and stigmasterol, which are rapidly incorporated into cells. The sterol contents of ASU preparations are the primary contributors to biological activity in articular chondrocytes. Preclinical in vitro and in vivo studies have demonstrated that ASUs have beneficial effects on promoting cartilage repair.
Collagen is an essential and major component of muscles, tendons, cartilage, ligaments, joints and blood vessels in humans or animals. Methylsulfonylmethane (MSM, or dimethylsulfone) is an organic sulfur compound belonging to a class of chemicals known as sulfones. It occurs naturally in some primitive plants and is present in small amounts in many foods and beverages. MSM is also known as dimethylsulfone, or DMSO2, a name that reflects its close chemical relationship to dimethyl sulfoxide (DMSO), which differs only in the oxidation state of the sulphur atom. MSM is the primary metabolite of DMSO in humans, and it shares some of the properties of DMSO.
It can be seen that tissue maintenance and building is a complex process that requires range of nutrients at the same time to provide synergistic effect to preserve and rebuild joint tissue. A need, therefore, exists for a new type of nutritional supplement that can be utilized to improve overall joint health.
The term “joint disorders” can be taken to include but not be limited to
a) osteoarthritis,
b) joint effusion,
c) joint erosion,
d) joint inflammation and pain,
e) joint calcification
f) the reduction or inhibition of metabolic activity of chondrocytes,
g) the reduction or inhibition of enzymes that degrade cartilage,
Menaquinone-7 (MK-7), sub-type of Vitamin K2 (Menaquinones), can exist as cis and trans isomers. The terms “cis” and “trans”, as used herein, denote a form of geometric isomerism in which two carbon atoms connected by a double bond will each have a hydrogen atom on the same side of the double bond (“cis”) or on opposite sides of the double bond (“trans”),
The chemical structure of MK-7 influences its ability to interact with subcellular structures, and thus determines its biological activity. Therefore, only the all-trans form of MK-7 is biologically significant. Among the various aspects of the invention, the dietary supplement includes the trans form of MK-7 that can exert an active role in joint cells metabolism.
Another aspect of the invention encompasses a dietary supplement having a balanced mixture of key compounds including trans form of MK-7, green-lipped mussel powder, eggshell membrane powder, vitamin D3, vitamin C, and ginger root extract that together promote the growth, repair, and maintenance of mammalian joint connective tissue. The supplement may be administered as a paste, chewable flavored tablet, capsule, or a powder appointed to be admixed with the food products. In preferred embodiments, the supplement properly will include additional excipients that will aid to balance metabolic needs for efficacy.
In accordance with one aspect of the present invention, the dietary supplements may be administered to a mammalian subject to prevent several joint disorders or indications, including but not be limited to
h) osteoarthritis,
i) joint effusion,
j) joint erosion,
k) joint inflammation and pain,
I) the reduction or inhibition of metabolic activity of chondrocytes,
m) the reduction or inhibition of enzymes that degrade cartilage,
n) the reduction or inhibition of the production of hyaluronic acid.
The dietary supplements may also be administered to a mammalian subject to decrease degradation of articular cartilage or disorders or indications resulting from degradation of articular cartilage. The dietary supplement includes a mixture of trans form of MK-7, green-lipped mussel powder, eggshell membrane powder, vitamin D3, vitamin C, and ginger root extract. The dietary supplement can, in accordance with generally known methods, be formulated to meet the needs of several mammalian subjects. It is contemplated, that one or more excipients being used during the formulation without departing from the scope of the invention.
