Living with arthritis often means looking for ways to manage joint pain, stiffness and inflammation. Natural supplements are popular because they may offer another way to support joint health, but knowing which ones are worth considering can be difficult. Some have encouraging research behind them, while others have limited evidence or benefits that remain uncertain.
From turmeric and omega-3 fatty acids to glucosamine, collagen and herbal extracts, there are many products marketed for arthritis. However, research findings vary, and a supplement that may help with one type of arthritis may not provide the same benefits for another.
This guide examines seven commonly used arthritis supplements, what scientific research suggests about their potential benefits, their limitations, and important safety considerations. It also explains what to look for when comparing products so you can make a more informed decision.

Quick Answer: Do Natural Supplements Help Arthritis?
Some natural supplements may offer modest symptom relief for certain people with arthritis, but the evidence varies considerably. No supplement has been established as a reliable treatment for all forms of arthritis, and benefits are not guaranteed.
- Omega-3 fatty acids: Have some evidence of modest benefits for rheumatoid arthritis symptoms.
- Turmeric and curcumin: Preliminary research suggests possible benefits for some osteoarthritis symptoms, particularly knee pain, but stronger evidence is needed.
- Glucosamine and chondroitin: Research has produced inconsistent results, and major medical guidelines differ in their recommendations.
- MSM: Has limited evidence supporting meaningful improvements in arthritis symptoms.
- Boswellia: Small studies suggest possible benefits for osteoarthritis, but better-quality research is needed.
- Devil’s claw: Has some evidence of benefits for osteoarthritis affecting the spine, hip and knee, although safety and long-term effectiveness remain concerns.
- Collagen peptides: Research is developing, but there is no convincing evidence that supplements rebuild damaged cartilage.
Natural does not automatically mean safe. Supplements can cause side effects, interact with prescription medications and vary in quality. They should not replace prescribed arthritis treatment.
How to Interpret the Evidence
Research on arthritis supplements can be difficult to interpret. Studies may involve different types of arthritis, ingredient formulations, doses, treatment periods and measures of improvement.
A positive result in one small study does not necessarily mean a supplement will provide meaningful relief in everyday use.
Throughout this guide, the evidence is described in three general categories:
- Some evidence: Research suggests a possible benefit, but important uncertainties remain.
- Mixed or limited evidence: Findings are inconsistent, or studies have significant limitations.
- Insufficient evidence: There is not enough reliable research to determine whether the supplement helps.
These descriptions are intended to help readers understand the available research. They are not formal medical grades or guarantees of effectiveness.
For additional background, see the National Center for Complementary and Integrative Health (NCCIH), which reviews research on natural health products and complementary approaches.
Comparing Popular Supplements for Arthritis
| Supplement | What the research suggests | Important limitation |
|---|---|---|
| Turmeric / curcumin | Preliminary research suggests possible benefits for some osteoarthritis symptoms. | Stronger evidence is needed to establish effectiveness. |
| Omega-3 fatty acids | May modestly improve some rheumatoid arthritis symptoms. | Evidence for osteoarthritis is less convincing. |
| Glucosamine | Research on osteoarthritis has produced inconsistent results. | Several major guidelines recommend against its use for certain forms of osteoarthritis. |
| Chondroitin | Some studies report improvements, particularly for certain formulations. | Results vary, and medical guidelines differ. |
| MSM | Limited research suggests possible improvements in some symptoms. | Meaningful benefits have not been established. |
| Boswellia | Small studies suggest possible improvements in osteoarthritis symptoms. | Larger, higher-quality studies are needed. |
| Devil’s claw | Some evidence suggests benefits for osteoarthritis of the spine, hip and knee. | Long-term effectiveness and safety remain uncertain. |
| Collagen peptides | Some studies have explored possible improvements in joint discomfort. | It has not been established that supplements rebuild damaged cartilage. |
The evidence summaries draw on NCCIH research reviews, published studies and medical treatment guidelines. They should not be interpreted as a ranking of the most effective supplements.
1. Turmeric and Curcumin
Turmeric is a spice commonly used in cooking that contains curcumin, a compound studied for its potential anti-inflammatory properties. Turmeric and curcumin supplements are widely marketed for joint discomfort, stiffness and inflammation.
What does the research suggest?
Some preliminary research suggests curcumin may help relieve certain symptoms associated with osteoarthritis, particularly knee osteoarthritis.
Several studies have reported improvements in knee pain and function. However, the available evidence is not strong enough to establish turmeric supplements as an effective treatment for arthritis generally.
Results from one formulation should not automatically be applied to another. Products can differ considerably in curcumin content, absorption and additional ingredients.
Turmeric supplements have also not been shown to rebuild damaged cartilage or stop arthritis from progressing.
For more information, see the NCCIH turmeric research and safety review.
What should you check on the label?
If you are considering a curcumin supplement, look for:
- The actual amount of curcuminoids per serving.
- Clear ingredient and serving-size information.
- Additional ingredients designed to increase absorption.
- Independent quality testing, where available.
- Relevant medication-interaction information and safety warnings.
Some formulations contain black pepper extract, also known as piperine, to increase curcumin absorption. Greater absorption does not automatically mean greater benefit, and some enhanced-bioavailability formulations have raised additional safety concerns.
Safety considerations
Turmeric supplements can cause digestive upset, nausea, reflux, diarrhea or constipation.
Liver injury has also been reported with some turmeric and curcumin products, particularly certain formulations designed to increase absorption.
Stop taking the supplement and seek medical advice if you develop symptoms such as unusual fatigue, nausea, loss of appetite, dark urine or yellowing of the skin or eyes.
Speak with a healthcare professional before using concentrated turmeric supplements if you take medications, have a medical condition or are considering combining several supplements.
Turmeric supplement to compare
Turmeric Curcumin with Black Pepper Extract — 95% Curcuminoids
When comparing this product with alternatives, check the actual curcuminoid amount per serving, the role of the black pepper extract, serving size and safety warnings. Do not assume that a higher advertised milligram figure means better results.
2. Omega-3 Fatty Acids
Omega-3 fatty acids include EPA and DHA, which are found in oily fish and fish oil supplements. Some supplements use algae-derived omega-3s instead.
These fats are involved in normal bodily processes, including those related to inflammation. Their potential role in arthritis has been studied, particularly in rheumatoid arthritis.
What does the research suggest?
Some clinical research suggests omega-3 supplements may modestly improve symptoms such as tender joints and morning stiffness in people with rheumatoid arthritis.
Some studies have also examined whether supplementation can reduce the need for anti-inflammatory medication.
However, results are not uniform, and omega-3 supplements are not a proven treatment for rheumatoid arthritis. They should not replace disease-modifying medication or other prescribed treatment.
Evidence that fish oil meaningfully improves osteoarthritis symptoms is much less convincing.
For a useful overview, see the NCCIH review of nutritional approaches to musculoskeletal pain and inflammation.
What should you check on the label?
If you are comparing omega-3 products, look for:
- The amount of EPA and DHA per serving, listed separately.
- The number of capsules required to reach the stated serving.
- Clear sourcing and ingredient information.
- Quality testing and contaminant-control information, where available.
- Fish and other allergen warnings.
A product advertised as containing 1,000 or 1,200 mg of fish oil may provide considerably less EPA and DHA than that total. Compare the actual active ingredients rather than relying on the headline number.
Vegan products made from algae may be an alternative for people who do not consume fish.
Safety considerations
Fish oil may cause an unpleasant aftertaste, nausea or digestive discomfort.
Higher supplemental doses may affect bleeding risk, and interactions with medications need to be considered.
Check with a pharmacist or healthcare professional before taking omega-3 supplements if you use anticoagulants or other medications that affect bleeding, have a medical condition or are considering a high dose.
Omega-3 supplement to compare
Omega-3 Fish Oil with EPA and DHA
When comparing fish oil supplements, pay particular attention to the combined EPA and DHA content rather than the total fish oil amount.
3. Glucosamine and Chondroitin
Glucosamine and chondroitin are substances associated with cartilage. They are commonly sold separately or in combination supplements marketed for osteoarthritis, particularly knee discomfort.
Because these substances occur naturally in cartilage, it has been suggested that taking them as supplements might support joint structure. However, this does not establish that supplements will restore cartilage or improve joint function.
What does the research suggest?
Research has produced inconsistent results. Some people report improvement, but many studies have not found meaningful benefits over placebo.
Medical guidelines also differ in their recommendations.
The American College of Rheumatology and Arthritis Foundation’s 2019 guideline strongly recommended against glucosamine for osteoarthritis of the hip, knee and hand. It also recommended against chondroitin for knee and hip osteoarthritis, while conditionally recommending it for hand osteoarthritis.
Other organizations have reached different conclusions for certain formulations, particularly prescription-grade chondroitin and glucosamine products.
The important point is that research findings for one formulation or joint should not automatically be applied to every supplement.
For more detail, see the NCCIH overview of glucosamine and chondroitin.
What should you check on the label?
If you are considering a combination product, check:
- The amount of glucosamine and chondroitin per serving.
- Whether MSM, turmeric or other ingredients have been added.
- The number of tablets required per day.
- Allergen information, including the source of glucosamine where relevant.
- Medication warnings and independent quality information.
Adding several ingredients does not establish that a formula works better than a simpler product.
Safety considerations
Glucosamine and chondroitin can interact with warfarin, an anticoagulant, and may increase bleeding risk.
Glucosamine may also affect blood glucose in some people.
Speak with a healthcare professional before starting these supplements, particularly if you take prescription medications or have diabetes.
Glucosamine combination supplement to compare
Glucosamine, Chondroitin, MSM, Turmeric and Boswellia Combination
This type of combination product brings together several ingredients marketed for joint support. Its inclusion here is not an endorsement of clinical effectiveness.
Before buying a multi-ingredient product, check the quantity of each ingredient per serving. If the amounts are unclear, it is difficult to compare the formula with research or evaluate whether it is suitable for you.
4. MSM (Methylsulfonylmethane)
MSM is a sulfur-containing compound sold as a dietary supplement, either by itself or in combination joint formulas.
It is marketed for joint comfort, flexibility and mobility, but marketing claims should not be confused with established clinical benefits.
What does the research suggest?
A limited number of studies have examined MSM for osteoarthritis, particularly knee osteoarthritis.
Some small studies have reported improvements in pain and physical function. However, the research is limited, and there is not enough reliable evidence to determine whether MSM provides meaningful or consistent improvements.
Its inclusion in a joint supplement does not establish that the product will help arthritis symptoms.
What should you check on the label?
If you are comparing MSM products, check:
- The amount of MSM per serving.
- Recommended serving instructions.
- Whether other ingredients have been added.
- Quality and manufacturing information.
- Any medication warnings.
Consider whether a standalone product would make it easier to evaluate tolerability than a combination containing several supplements.
Safety considerations
MSM may cause digestive upset, skin reactions or other side effects. Long-term safety information is limited.
Ask a healthcare professional whether it is appropriate for you, particularly if you take medications or have existing health conditions.
5. Boswellia Serrata
Boswellia serrata is a tree whose resin has been used in traditional herbal practices. Extracts are sold as supplements for joint discomfort and inflammation.
Boswellia is sometimes included in combination joint supplements alongside glucosamine, chondroitin, MSM and turmeric.
What does the research suggest?
Several small studies suggest that oral boswellia extracts may help reduce some symptoms associated with osteoarthritis, including joint pain and stiffness.
However, most studies have been small or of limited quality. There is not enough high-quality evidence to establish boswellia as an effective arthritis treatment.
Different products may use different extracts and concentrations, so results from one preparation cannot automatically be applied to every boswellia supplement.
For additional information, see the NCCIH Boswellia research and safety review.
What should you check on the label?
Look for:
- The botanical name, Boswellia serrata.
- The amount per serving.
- The type of extract.
- Standardization information, where provided.
- Additional ingredients and medication warnings.
Be cautious of claims that promise to eliminate inflammation, prevent joint damage or reverse arthritis.
Safety considerations
Boswellia is generally considered reasonably well tolerated in the amounts studied, although some people may experience digestive discomfort or other side effects.
Information about interactions with medications and long-term use remains limited.
Discuss it with a pharmacist or healthcare professional before use, especially if you take prescription medication or are considering combining several herbal products.
6. Devil’s Claw
Devil’s claw is an herb native to southern Africa. Its extracts have been studied for certain types of musculoskeletal discomfort, including osteoarthritis and back pain.
It is sold in various forms, including capsules and tablets.
What does the research suggest?
There is some evidence that devil’s claw may provide benefits for osteoarthritis affecting the spine, hip and knee.
Research also suggests possible modest short-term benefits for certain types of low-back pain.
However, this does not establish devil’s claw as a treatment for all forms of arthritis. More research is needed to determine its long-term effectiveness and safety.
Safety considerations
Devil’s claw may not be suitable for everyone.
It may affect heart rate and blood pressure and may lower blood glucose levels. People with heart or circulatory conditions, diabetes, gallstones or peptic ulcers should be particularly cautious.
Its potential interactions and suitability depend on a person’s medications and health conditions.
Do not assume an herbal product is safe simply because it is sold without a prescription. Discuss it with a healthcare professional before use.
For further information, see the NCCIH review of nutritional approaches to musculoskeletal pain.
7. Collagen Peptides
Collagen is a protein found in connective tissues, including cartilage, tendons, ligaments and skin.
Collagen supplements are sold as powders, capsules and other formulations, often marketed for skin, bones and joints.
Products may contain hydrolyzed collagen, sometimes called collagen peptides, or other forms such as undenatured type II collagen. These forms are not interchangeable, and research on one formulation does not necessarily apply to another.
What does the research suggest?
Research into collagen supplements for joint symptoms is developing.
Some studies have explored possible improvements in joint discomfort and physical function, but the clinical significance of reported benefits remains uncertain.
There is no convincing evidence that taking collagen supplements rebuilds damaged cartilage or reverses osteoarthritis.
Collagen may be a source of protein, but it should not be viewed as a proven way to restore joint structure.
What should you check on the label?
Consider:
- The type of collagen and the amount per serving.
- Whether the product is hydrolyzed or uses another formulation.
- The source, such as bovine, marine or another animal-derived ingredient.
- Added sweeteners, flavors and other ingredients.
- Allergens and dietary preferences.
Safety considerations
Collagen products can cause digestive discomfort, and suitability depends on the source and other ingredients.
People with food allergies should check the label carefully, particularly when using marine or bovine collagen products.
Collagen supplement to compare
Sports Research Collagen Peptides — Hydrolyzed Type I and III
This product is a hydrolyzed collagen powder marketed for skin, nails, bones and joints. Check its current ingredient list, serving size and source before purchasing.
Its inclusion in this guide does not establish that it will improve arthritis symptoms.
How to Choose an Arthritis Supplement
Rather than buying several products at once, start by clarifying what you hope to achieve and whether there is credible evidence that a supplement may help with that specific problem.
These steps can help you make a more informed decision.
1. Consider the type of arthritis
Osteoarthritis and rheumatoid arthritis are different conditions.
Research about omega-3 supplements for rheumatoid arthritis, for example, should not be taken as proof that they will help osteoarthritis.
If you are unsure which type of arthritis you have, discuss your symptoms and diagnosis with a healthcare professional.
2. Look for evidence about the actual ingredient
A supplement may advertise an ingredient that has been studied, but the product may contain a different form, concentration or combination.
Check whether the research relates to the actual ingredient and formulation rather than relying on general claims about inflammation or joint health.
3. Read the complete label
Check the amount of each active ingredient per serving, recommended serving size, additional ingredients, allergens and warnings.
Be cautious of products that hide ingredient amounts within proprietary blends.
4. Consider independent quality testing
Independent testing can provide useful information about ingredient identity, purity and whether a product contains what its label claims.
It does not prove that the supplement works for arthritis.
Look for credible testing or certification information rather than relying solely on marketing claims.
5. Discuss safety before starting
A pharmacist or healthcare professional can help identify potential interactions and assess whether a supplement is appropriate for your circumstances.
This is particularly important if you take prescription medications, have a chronic health condition or already use several supplements.
6. Set realistic expectations
Some studies evaluate supplements over weeks or months, but there is no universal timeline for improvement.
A supplement may not help at all. Avoid increasing the dose or combining more products in an attempt to force a result.
If you decide to try one, discuss a reasonable period for evaluating whether it is worthwhile.
Supplement Safety: What to Know Before You Buy
Even when a supplement is sold over the counter, it can have meaningful risks.
Before starting one, consider the following:
Medication interactions: Supplements may change the effects or risks of prescription and nonprescription medicines.
Existing health conditions: Liver or kidney problems and other medical conditions can affect whether a product is suitable.
Surgery: Tell your healthcare team about supplements before a planned procedure. Some products may affect bleeding or interact with medications used during surgery.
Multiple products: Combining supplements is not automatically more effective or safer. Ingredients can overlap, and side effects may become harder to identify.
Product quality: Labels, ingredient concentrations and manufacturing quality can vary.
Delayed treatment: Relying on supplements instead of appropriate medical care may delay effective treatment.
People with rheumatoid arthritis should be particularly careful not to replace prescribed disease-modifying medication with supplements. Controlling the disease and preventing joint damage require appropriate medical management.
If you decide to try a supplement with your healthcare professional’s agreement, keep track of the product, serving size, start date, possible side effects and any changes in symptoms. This makes it easier to assess whether continuing is worthwhile.
Are Natural Supplements Regulated?
Regulations differ between countries.
In the United States, dietary supplements are regulated differently from prescription and over-the-counter medicines. The FDA does not approve dietary supplements for safety and effectiveness before they are marketed.
In Canada, natural health products are subject to Health Canada licensing requirements. Licensed products carry a Natural Product Number (NPN) or Drug Identification Number–Homeopathic Medicine (DIN-HM), as applicable.
A licence or quality certification does not prove that a supplement is effective for arthritis, but it can provide additional information about product regulation and permitted claims.
For Canadian readers, see Health Canada’s information about natural health products.
What May Help Arthritis Beyond Supplements?
Supplements are only one part of arthritis self-management, and many have uncertain benefits. Depending on the type of arthritis and individual needs, other strategies have stronger support.
These may include:
- Appropriate exercise: Regular strength and aerobic exercise can help maintain mobility, muscle strength and everyday function.
- Joint protection: Using appropriate techniques and assistive tools can reduce unnecessary strain during daily activities.
- Activity pacing: Balancing activity with rest may help manage fatigue and avoid overdoing things.
- Weight management: Maintaining a healthy weight, when appropriate, can reduce stress on weight-bearing joints.
- Balanced nutrition: A varied diet provides important nutrients for general health.
- Sleep support: Addressing sleep difficulties can help improve overall well-being and daily functioning.
- Medical treatment: Following prescribed treatments and attending recommended medical appointments remain important, particularly with inflammatory arthritis.

Frequently Asked Questions
Which supplement has the strongest evidence for arthritis?
There is no single supplement that has been established as the best option for all forms of arthritis. Omega-3 supplements have some evidence of modest benefits for rheumatoid arthritis symptoms. Evidence for many supplements marketed for osteoarthritis is mixed, limited or insufficient.
Can supplements rebuild cartilage?
There is no convincing evidence that commonly marketed arthritis supplements can rebuild damaged cartilage or reverse established osteoarthritis. Claims about cartilage repair should be treated cautiously.
How long do arthritis supplements take to work?
There is no universal timeline. Research periods differ, and any benefit may be small or absent. If you try a supplement after discussing it with a healthcare professional, agree on a reasonable period for evaluating it rather than continuing indefinitely without a clear benefit.
Can I take several arthritis supplements together?
Combining supplements is not automatically safe or more effective. Ingredients can overlap, and interactions with medications may occur. Ask a pharmacist or healthcare professional to review the complete list of products you take.
Are natural supplements safer than arthritis medication?
Not necessarily. Natural products can cause side effects, interact with medication and vary in quality. Prescription treatments also have risks, but they may have better-established benefits for specific conditions. Treatment decisions should consider both potential benefits and risks.
Should I stop my arthritis medication if I start a supplement?
No. Do not stop or change prescribed medication without consulting the clinician who manages your treatment. Supplements have not been shown to replace appropriate treatment for inflammatory arthritis.
Final Thoughts
Some natural supplements may provide modest symptom benefits for certain people with arthritis, but the evidence is far from uniform.
Omega-3 fatty acids have some supportive evidence for rheumatoid arthritis symptoms. Research on turmeric, glucosamine, chondroitin, MSM, boswellia, devil’s claw and collagen has varying degrees of uncertainty.
The most useful approach is to identify your specific needs, check the evidence for the ingredient and formulation, review possible interactions and avoid products that promise dramatic results or cartilage repair.
A supplement is worth considering only when its possible benefits, uncertainties, cost and risks make sense for you. It should complement—not replace—appropriate arthritis care.
