cissus (nice and standardized extracts), lots of fish oil, and GSM/chondroitin are all good products that do what they're supposed to and more.
personally i dose my fish oil in very concentrated liquigels, striving more for maximum DHA/EPA daily... the concentrated products obviously tend to have less overall oil thought. i'm not certain, but usually i take (overall oil) ~5g/day off cycle, and while oncycle will reach doses up to 12g or more even.
what no one has mentioned yet and what will solve you're problems better than the other stuff, especially when used in conjunction with each other; hyaluronic acid...
this is one of the most versatile substances around, used for tissue repair, joint lubrication, fluid viscosity, skin/hair/nail/cosmetic products, even cancer treatment. I've had great relief after running into pains during some extremely dry designer cycles ive experimented with.
read for yourself... (info of relevance copy/pasted from wiki article of hyaluran)
"Until the late 1970s, hyaluronan was described as a "goo" molecule, a ubiquitous carbohydrate polymer that is part of the extracellular matrix.[6] For example, hyaluronan is a major component of the synovial fluid and was found to increase the viscosity of the fluid. Along with lubricin, it is one of the fluid's main lubricating components.
Hyaluronan is an important component of articular cartilage, where it is present as a coat around each cell (chondrocyte). When aggrecan monomers bind to hyaluronan in the presence of link protein, large highly negatively-charged aggregates form. These aggregates imbibe water and are responsible for the resilience of cartilage (its resistance to compression). The molecular weight (size) of hyaluronan in cartilage decreases with age, but the amount increases.[7]
Hyaluronan is also used to treat osteoarthritis of the knee.[77] Such treatments, called viscosupplementation, are administered as a course of injections into the knee joint and are believed to supplement the viscosity of the joint fluid, thereby lubricating the joint, cushioning the joint, and producing an analgesic effect. It has also been suggested that hyaluronan has positive biochemical effects on cartilage cells. However, some placebo controlled studies have cast doubt on the efficacy of hyaluronan injections, and hyaluronan is recommended primarily as a last alternative to surgery.[78][79] Oral use of hyaluronan has been lately suggested, although its effectiveness needs to be demonstrated. At present, there are some preliminary clinical studies that suggest that oral administration of Hyaluronan has a positive effect on osteoarthritis, but it remains to be seen if there is any real benefit to the treatment.
Dry, scaly skin (xerosis) such as that caused by atopic dermatitis (eczema) may be treated with a prescription skin lotion containing sodium hyaluronate as its active ingredient.[80]
Hyaluronan has also been used in the synthesis of biological scaffolds for wound healing applications. These scaffolds typically have proteins such as fibronectin attached to the hyaluronan to facilitate cell migration into the wound. This is particularly important for individuals with diabetes who suffer from chronic wounds.[88] "
I've typically dosed it at a minimum of 100mg, usually around or above 200mg....its up to you and how your joints are feeling. as a reference point, 50mg 2x/day is the standard dose in female skin care supplements used to plumpen the lips and eliminate facial wrinkles, much like the pharmaceutical industry's drugs restylane and botox(but via nerve paralyzation; not lubricative / anti-inflammatory action like). it's fairly good stuff andafter pulling those quotes was reading about how effective it is orally compared to injected restylane for women looking for those angelina jolie DSL's.
never been disappointed with the stuff. give it a shot.
