It also explains what to look for when choosing supplements and a list of quality products.

Typical doses of curcumin are around 1,000 milligrams (mg) per day for four to 16 weeks.
Glucosamine supplements that have been independently certified include:

At this level, it is generally considered safe for up to three years.
Is Glucosamine or Fish Oil Better for Joints?
Because joint supplements are poorly studied, it isnt clear whether fish oil is better than glucosamine.
Chondroitin Sulfate

Chondroitinis the most abundant glycosaminoglycan in cartilage and contributes to the resiliency of cartilage.
Chondroitin is also important in blocking enzymes that can destroy cartilage.
Chondroitin sulfate supplements are intended to enhance the shock-absorbing properties of collagen and prevent the further breakdown of cartilage.
Chondroitin is commonly co-formulated with glucosamine.
Glucosamine and chondroitin are often taken as a combination therapy to treat osteoarthritis.
Research suggests that it may also help reduce jointinflammationand pain.
While glucosamine and chondroitin have scant clinical research to support their use, MSM has even less.
People who endorse the product believe that the sulfur contained in MSM helps ligaments maintain flexibility and strength.
RA is an autoimmune disease that causes joint pain.
The effects of vitamin D on joint pain havent been well studied.
CBD
CBD oil is oil derived from the cannabis plant.
It is thought to have anti-inflammatory properties and it doesnt make you high the way other cannabis products do.
Some people believe CBD oil is good for joint pain, but the evidence for its effectiveness isnt clear.
Other Joint Supplements
Several other compounds show promise for easing arthritis pain.
Because of this, you better be on guard when reviewing the manufacturers claims.
When youre shopping for supplements, pay attention to the claims the manufacturer is making.
If the claim sounds overblown or too good to be true, it probably is.
For example, claims that a product will reverse joint damage or cure arthritis are false.
Start by browsing reputable retailers such as pharmacies.
If shopping in person, look for a lot and batch number.
This is a sign that the manufacturer has quality control protocols in place.
Some products are combination formulas that contain more than one supplement.
Buying combination formulas can save on overall costs.
Are Joint Supplements Worth the Money?
Supplements arent evaluated by the FDA for safety or effectiveness.
Most have limited research to back them up, and they can be expensive.
The best way to determine if joint supplements are right for you is to consult your healthcare provider.
Summary
Supplements are sometimes recommended for treating joint pain due to osteoarthritis and other causes.
So far the evidence for the effectiveness of any supplement is limited.
The supplements that have the best evidence to support them include curcumin, glucosamine sulfate, and chondroitin sulfate.
Other supplements have fewer studies to support them.
Always talk to your healthcare provider about supplement use and whether it is right for you.
Even so, quality matters.
