Nutritional Supplements for Musculoskeletal Health Info Evidence
Reviewed by Dr Kieran Hirpara, Specialist Orthopaedic Surgeon Last reviewed
What it is
Nutritional supplements are extra nutrients you take by mouth, such as proteins, amino acids (the building blocks of protein), fish oils, or joint products like glucosamine and chondroitin. They are not medicines that fix a joint. They support your body while it heals or copes with wear-and-tear arthritis.
People consider them at different times. If you have arthritis, some supplements may ease pain and help your joints move better. If you are having surgery, such as a joint replacement or ligament repair, extra protein around the time of surgery may help protect your muscles while you recover. Older people, especially those unable to exercise, may benefit from specific supplements [1]. People who are undernourished before an operation can also be helped with nutrition advice and supplements [2].
How they work depends on the supplement. Glucosamine may help by encouraging your joint lining to make more of its own lubricating fluid [3]. Fish oils (omega-3 fats) may calm irritated joints and protect cartilage, the smooth surface inside the joint [4]. Protein and amino acids give your muscles the raw material they need so they waste less during recovery from surgery [5].
A few honest caveats. Peptide supplements are not recommended as a replacement for standard orthopaedic care, because there is not enough good evidence yet on how well they work or how safe they are [6]. Creatine did not help patients in the first 12 weeks of rehab after ligament reconstruction [7]. And if you play competitive sport, check any supplement carefully, because some contain substances that could breach antidoping rules [8].
Your doctor can talk through which options, if any, might suit your situation.
Does it work?
The honest answer is that it depends on the supplement and the situation. Some have solid support. Others do not.
For arthritis, several supplements have been tested in trials. Glucosamine sulfate and anti-inflammatory medicines reduced pain and improved function in knee wear-and-tear arthritis, and may slow joint damage [9]. Chondroitin relieved pain and improved physical function more than a dummy tablet, while glucosamine helped with stiffness [10]. Collagen peptides eased pain in people with knee arthritis compared with a dummy tablet [11]. For hand arthritis, glucosamine and chondroitin may be reasonable options as part of a broader treatment plan [12]. An eight-week collagen supplement improved pain, quality of life and some movement tests in people with a torn meniscus, the shock-absorbing pad inside the knee [13]. Collagen has also been tried as an injection rather than taken by mouth: in one observational study, a collagen injection near the shoulder tendon reduced pain and supported recovery for up to six months in people with rotator cuff problems [14].
Around surgery, the picture is more mixed. A balanced nutritional supplement lowered complication rates and deaths at 120 days after hip fracture surgery [15]. An amino acid supplement led to fewer complications after joint replacement and was low risk [16]. Protein supplements are easy to add to your care around an operation, and any benefit to muscle strength could lower the chance of falls or fracture near the new joint later on [17]. But effects on muscle strength and function overall are mixed [18], and getting patients properly nourished before spine surgery is often held back by inconsistent routines and people not sticking to the plan [19].
There are limits too. For one fatty acid (EPA, an omega-3 fat), early work suggests it might help slow arthritis after a cartilage injury, but this is not yet proven in strong trials [4]. And protein beyond about 1.6 g/kg/day does not add further muscle benefit when combined with resistance training [20]. Peptide supplements should not replace standard orthopaedic care, because good evidence on their benefit and safety is still lacking [6].
Your doctor can help you weigh which, if any, might be worth trying.
What are the risks?
Most of these supplements have a good safety record, but that does not mean they are risk free. The clearest finding from research is on glucosamine and chondroitin: studies describe a good safety profile for both, and glucosamine sulfate may relieve pain with few side effects [21] [22]. Even so, researchers note there are still unanswered questions about the long-term effects and the right amount to take [22].
Some risks are about what a supplement does not do. Creatine did not help patients during the first 12 weeks of rehabilitation after ligament reconstruction [7]. Peptide supplements should not replace standard orthopaedic care, because there is not enough good evidence yet on how well they work or how safe they are [6]. If you play competitive sport, some supplements contain substances that could breach antidoping rules, which can harm your health, your performance and your reputation [8].
Around surgery, the picture is more encouraging but not settled. Oral nutritional supplements and dietetic help are described as low-risk interventions for older people after hip fracture [23]. A commercially available amino acid supplement led to fewer complications after surgery and was low risk [16]. But intravenous protein or amino acid supplements around joint replacement show mixed effects on muscle strength and function, so the benefit is not guaranteed [18].
Two honest limits. Research on EPA, an omega-3 fat, for slowing arthritis after a cartilage injury is still early, and it has not been proven in strong trials [4]. And taking more protein than about 1.6 g/kg/day does not add further muscle benefit when combined with resistance training, so more is not always better [20].
Your doctor can talk through what these findings mean for you, and which options carry the least uncertainty in your situation.
Is it right for you?
Supplements tend to suit people in a few situations. If you are older and undernourished before an operation, nutrition advice plus amino acids and micronutrients are two ready options your doctor can choose for you [2]. If you have broken a hip, oral nutritional supplements and dietetic help are low-risk supports that may improve outcomes in older people [23]. If you cannot exercise, specific supplements alone may still help, as a study of vitamin D and leucine-enriched whey protein showed [1].
Some situations are less clear cut. Around joint replacement, intravenous protein or amino acids have mixed effects on muscle strength and function [18]. If you already take protein and do resistance training, more than about 1.6 g/kg/day adds no further muscle benefit [20]. For a cartilage injury, EPA (an omega-3 fat) is promising but not yet proven in strong trials [4].
Compared with the alternatives, supplements are a support rather than a fix. They sit alongside standard care, not instead of it. Peptide supplements should not replace standard orthopaedic treatment [6].
This is a shared decision. Your doctor can help you weigh whether a supplement fits your situation, your surgery and your goals. The risks section above covers safety in detail, so read that before deciding.
The bottom line
Supplements can be worth considering as a support, not a fix. Some may ease arthritis pain or help your body around surgery, but the benefits are usually modest and vary from person to person. The most important caveat: they sit alongside standard care, never instead of it. Talk with your doctor before starting anything, especially if you play competitive sport.

How It Works
Mechanisms of Action
- Glucosamine may exert analgesic properties through the stimulation of hyaluronic acid production in human osteoarthritic synovium [32].
- Omega-3 fatty acids protect cartilage from acute injury by reducing the mechanical sensitivity of chondrocytes [16].
Perioperative and Postoperative Recovery
- Perioperative essential amino acid supplementation prevents rectus femoris muscle atrophy and accelerates early functional recovery after total knee arthroplasty [30].
- Protein supplementation appears to have beneficial effects on mitigating muscle atrophy in the postoperative period following ACL reconstruction, total hip arthroplasty, total knee arthroplasty, and surgical treatment of hip fracture [24].
- Protein supplementation is a low-cost intervention that is easy to incorporate into perioperative management, and its beneficial effects on muscle strength could potentially reduce the risk of longer-term complications such as falls and periprosthetic fracture [20].
- Oral nutritional supplementation and dietetic assistance represent low-risk interventions that may improve morbidity and mortality in older people after hip fracture [17].
Osteoarthritis and Joint Pain
- Collagen peptides provide significant pain relief in patients with knee osteoarthritis compared to placebo [27].
- An eight-week collagen-based supplement has a positive effect on pain, quality of life levels, and some functional test results in patients with meniscopathy [25].
- Subacromial injection of hydrolyzed collagen is effective in reducing pain and supporting functional recovery in patients with rotator cuff tendinopathy, with effects observed after the first injection and persisting up to six months [29].
- Glucosamine sulfate has the potential to relieve pain and improve function with low side effects, though unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10].
- The evidence supports the efficacy of glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7].
Muscle Mass and Strength
- Protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute to resistance training-induced gains in fat-free mass [18].
Limitations and Safety
- Patients do not benefit from creatine supplementation during the first 12 weeks of rehabilitation after anterior cruciate ligament reconstruction [26].
- The appropriate use of some supplements can benefit the athlete, but others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12].
