<<<5>>> Osteoarthritisarthrose is the most common joint disease: it affects millions of people, especially after age 50, and most often develops in the knee, the hip or the hands. Faced with it, many seek natural solutions to relieve pain without relying solely on anti-inflammatories.
Good news: several natural approaches have solid evidence. Less good news: the market is also full of products with exaggerated claims. This article separates fact from fiction, based on studies, to tell you what actually relieves osteoarthritis , what helps less, and how to build an effective long-term strategy. With one rule of honesty: osteoarthritis is not "cured," but you can live significantly better with it.
<<<30>>> Osteoarthritisarthrose is cartilage wear that cannot be cured, but its symptoms can be relieved. Among natural solutions, turmeric (curcumin) is the best-documented: it reduces knee osteoarthritis pain according to multiple meta-analyses. Hydrolyzed collagen anddevil's claw also have promising evidence, and omega-3s modulate inflammation. In contrast, glucosamine and chondroitin, very popular, have weak or uncertain effects. The foundation remainsadapted physical activity, maintaining a healthy weight and an anti-inflammatory diet. Supplements are a support, not a treatment.
Osteoarthritis in brief: what you can and cannot do
To choose your solutions wisely, you must first understand what is happening. In osteoarthritis, the cartilage that covers the ends of bones and cushions movements gradually wears away. As it thins, surfaces slide less smoothly, the joint becomes painful and stiff, sometimes inflamed. It is a chronic and progressive disease, particularly common in the knee (knee osteoarthritis), hip (hip osteoarthritis), and hands.
Let's be clear and honest about one essential point: worn cartilage does not regenerate. No supplement, no plant, no medication "repairs" established osteoarthritis. Beware of any product that promises to "regenerate cartilage" or "cure osteoarthritis": it is a promise that science does not support.
But that doesn't mean you are powerless, far from it. What you can do is actually considerable: relieve pain, reduce inflammation, improve mobility, strengthen the muscles that support the joint, and slow progression. The goal is not to cure, but to live better with your osteoarthritis day to day. And on this front, the natural approach and lifestyle changes have a real role to play, in addition to medical follow-up.
This article focuses on osteoarthritis. If your joint pain has another cause or you don't have a diagnosis, start with our more comprehensive guide: joint pain: causes and natural solutions.
Supplements with real evidence
This is the question everyone asks: which supplements are really worth it? Rather than presenting them all equally, here is an honest look at what the studies say, from most to least documented.
Significant reduction in knee pain, with fewer side effects than conventional anti-inflammatory drugs.
Significant effect on short-term pain in a large meta-analysis.
Pain reduction in higher-quality studies, to be confirmed.
Action on inflammation, particularly useful when the inflammatory component is marked.
Weak or uncertain effects according to the most rigorous reviews (see below).
Turmeric: the best natural evidence
Turmeric turmeric, via its active ingredient curcumin, is the best-supported natural anti-inflammatory for osteoarthritis. According to a network meta-analysis by Zhao et al. 2023 in the Journal of Ethnopharmacology, covering 23 studies and 2,175 patients with knee osteoarthritis, curcumin significantly reduces pain (WOMAC score) compared to placebo, with a favorable tolerability profile and fewer side effects than non-steroidal anti-inflammatory drugs (DOI: 10.1016/j.jep.2023.117493). It is one of the rare natural ingredients at this level of evidence.
A decisive practical point: curcumin is poorly absorbed on its own. For it to be effective, it must be combined with piperine (black pepper) or a fatty substance, or choose a form with enhanced bioavailability. Without this, a significant portion passes through without being assimilated. Discover our organic turmeric.
Collagen, a component of cartilage
Collagen collagen is the main protein of cartilage. In hydrolyzed form (well-absorbed peptides), it is among supplements with interesting evidence. According to the large meta-analysis by Liu et al. 2018 in the British Journal of Sports Medicine, which compared 20 supplements in 69 trials, hydrolyzed collagen is among the rare ones showing a significant effect on short-term pain (DOI: 10.1136/bjsports-2016-097333). Our marine collagens are available in powder and in drink.
Harpagophytum, Devil's Claw
<<<7>>> Harpagophytumharpagophytum is a plant traditionally used for joint pain. According to a review by Brien et al. 2006 in the Journal of Alternative and Complementary Medicine, the highest quality studies suggest that it is effective at reducing osteoarthritis pain , with a low risk of adverse effects compared to conventional anti-inflammatory drugs, even though larger trials remain desirable (DOI: 10.1089/acm.2006.12.981). See our organic harpagophytum.
Omega 3, on the inflammatory front
<<<16>>> Omega 3 oméga 3 (EPA, DHA) modulate inflammation. According to a review by Navarini et al. 2017 in Lipids in Health and Disease, their supplementation may improve certain joint symptoms in inflammatory contexts, including pain and stiffness (DOI: 10.1186/s12944-017-0586-3). They are a good foundational supplement, especially when inflammation is present. See our Omegavie® omega 3.
To combine several of these active ingredients without multiplying bottles, the Joint Care Nutripack offers a formula designed for joint comfort. And for targeted localized relief, the joint gel applies directly to the area.
Glucosamine and Chondroitin: What Does the Science Say?
This is a subject that requires editorial courage, because it goes against a deeply held belief. Glucosamine and chondroitin are by far the supplements most associated with osteoarthritis in the public mind. You find them everywhere. Yet their actual effectiveness is far more debated than their popularity would suggest.
According to the landmark meta-analysis by Liu et al. 2018, which evaluated 20 supplements in 69 clinical trials, glucosamine and chondroitin showed only weak or clinically modest effects on osteoarthritis pain, unlike hydrolyzed collagen or curcumin which perform much better (DOI: 10.1136/bjsports-2016-097333). Other rigorous reviews reach similar conclusions: the effect, when it exists, is modest.
Should you throw them away then? Not necessarily. They are safe and well tolerated, and some people report a subjective benefit (which may include an element of placebo effect, which is nothing to dismiss when you're suffering). The message is not "it never works," but rather: don't rely on them alone, and know that there are better-documented options. This is precisely why, at Nutrition•pro, we chose to highlight turmeric and collagen rather than capitalize on glucosamine's popularity. It's a matter of honesty with the evidence.
Anti-inflammatory eating
Your plate plays a dual role in osteoarthritis: it acts on the inflammatory environment, and it determines your weight, which influences the load on your joints. This is a lever not to be overlooked.
Prioritiesinclude the basics of the Mediterranean diet: fatty fish (salmon, mackerel, sardines, rich in omega-3), colorful fruits and vegetables (antioxidants), red berries, olive oil, nuts and seeds, legumes, and anti-inflammatory spices such as turmeric (with pepper) and ginger. This eating pattern has shown benefits for chronic inflammation.
Limit: refined sugars and sodas, ultra-processed products, excess red meat and processed meats, poor-quality fats (fried foods, hydrogenated oils). These foods perpetuate an unfavorable inflammatory environment.
Weight, the number one lever for weight-bearing joints. Every extra pound multiplies the load on your knees and hips with each step. If overweight, losing even some weight is one of the most effective actions to relieve knee or hip osteoarthritis. Our guides 27 science-proven tips for losing weight and losing weight after 50 can help, often a decisive step after age fifty.
Moving to preserve your joints
This is one of the biggest misunderstandings about osteoarthritis: thinking you need to "spare" the joint by moving as little as possible. It's the opposite. Adapted movement is one of the pillars of management, and it is widely recommended.
Why? Because cartilage is nourished by movement (it has no blood vessels of its own; movement circulates nutrients from the synovial fluid). Because activity maintains mobility and fights stiffness. And especially because it strengthens the muscles that support the joint and absorb some of the stress: strong thighs relieve an arthritic knee.
Good activities are gentle and low-impact : walking, swimming and aquatic exercise (water supports the body), cycling, yoga, stretching. The goal is consistency, not intensity. Avoid: high-impact sports and sharp twisting motions on the affected joint. If in doubt, a physical therapist can suggest a program tailored to your osteoarthritis.
Building your routine based on intensity
There is no one-size-fits-all protocol: it all depends on the severity of your osteoarthritis and your situation. Here are three scenarios to help you find your way, to be adapted with your doctor.
Regular gentle activity, healthy weight, anti-inflammatory diet, and turmeric as foundational support. The most cost-effective approach.

For targeted relief on the affected area during difficult moments, to complement your foundational actives. Medical advice is still recommended in case of a flare-up.
See the gel →In all cases, keep two principles in mind: consistency (foundational actives are taken as courses over time, not sporadically) and patience (benefits develop over weeks, not days). And never pit these approaches against your medical treatment: they complement it.
When to consult and precautions
Osteoarthritis requires long-term management, ideally with medical support. A few situations warrant professional advice without delay.
Consult a doctor:
- To obtain or confirm an osteoarthritis diagnosis, and establish a treatment plan
- In case of intense, sudden pain, or pain that worsens rapidly
- If the joint is swollen, warm, or red (possible inflammatory flare-up or other cause)
- Before starting a supplement course if you are taking medication (anticoagulants in particular)
- If the discomfort significantly limits your activities or independence
Precautions on the actives: turmeric at high doses and devil's claw may interact with anticoagulants and are not recommended in case of ulcers or gallstones for devil's claw. Always consult your doctor or pharmacist before combining supplements and treatments.
Finally, remember that dietary supplements do not replace a varied diet, a healthy lifestyle, or medical treatment. They are a support, to be integrated into an overall strategy.
Frequently asked questions
What is the best natural supplement for osteoarthritis?
Turmeric (curcumin) is the best-documented natural supplement against osteoarthritis. According to a network meta-analysis by Zhao 2023 covering 23 studies and 2,175 patients, curcumin significantly reduces knee osteoarthritis pain, with fewer side effects than conventional anti-inflammatory drugs. Hydrolyzed collagen and devil's claw are also among the options with interesting evidence. No supplement cures osteoarthritis: they help relieve symptoms.
Can osteoarthritis be treated naturally?
No, osteoarthritis cannot be cured, neither naturally nor with medications: once cartilage is worn, it does not regenerate. However, you can relieve pain, improve comfort and mobility, and slow progression through a holistic approach: adapted physical activity, maintaining a healthy weight, anti-inflammatory diet, and certain supplements such as turmeric. The goal is to live better with it, not to cure it.
Is glucosamine and chondroitin effective against osteoarthritis?
Their effectiveness is debated and generally weaker than commonly believed. According to a meta-analysis of 69 trials (Liu 2018), glucosamine and chondroitin, though very popular, showed weak or clinically insignificant effects on osteoarthritis pain. Some people find benefit from them, but the evidence is less solid than for turmeric or collagen. This is why it is useful to know about better-documented alternatives.
What foods should be avoided in case of osteoarthritis?
It is advisable to limit pro-inflammatory foods: refined sugars and sodas, ultra-processed products, excessive red meat and processed meats, poor-quality fats (fried foods, hydrogenated oils). Conversely, an anti-inflammatory Mediterranean-style diet (fatty fish, colorful fruits and vegetables, olive oil, red berries) can help reduce discomfort and maintain a healthy weight, essential for relieving weight-bearing joints.
Is physical activity good or bad for osteoarthritis?
Adapted physical activity is beneficial, and even recommended. Contrary to popular belief, immobility worsens stiffness and weakens the muscles that support the joint. Gentle and regular activities (walking, swimming, cycling, yoga) maintain mobility, nourish cartilage and strengthen muscles. You simply need to avoid high-impact or traumatic activities for the affected joint, and adapt the effort to your pain level.
