Osteoarthritis is the most prevalent joint disease in the world: progressive degeneration of articular cartilage with low-grade inflammation, subchondral bone remodeling, osteophyte formation, and mechanical pain that increases with activity; it predominantly affects the knee, hip, hands, and spine; it is the leading cause of joint disability in older adults and one of the main reasons for primary care visits; nutritional and supplemental interventions are usually helpful as a complement to comprehensive management (which includes weight control, adapted exercise, physical therapy, and analgesia when appropriate).
The most powerful modifiable risk factor for osteoarthritis (especially of the knee and hip) is overweight/obesity: each additional kilogram adds 3-6 kg of load on the knee when walking. Reductions of 5-10% of body weight produce significant clinical improvements in pain and function even without other interventions.
Adapted physical exercise is the second most important factor: - Muscle strengthening (quadriceps for the knee, glutes for the hip): protects the joint, reduces pain, and improves function. - Low-impact aerobic exercise (swimming, cycling, walking): preserves mobility and weight. - Stretching and controlled joint mobility: maintain range of motion.
The idea of "not using the joint because it hurts" is counterproductive; immobilization accelerates joint deterioration and the loss of protective muscle.
Glucosamine and chondroitin: mixed support; some studies show modest benefit, others are negative. Current clinical guidelines (OARSI, ACR) have variable recommendations. Probably useful in some people with mild to moderate osteoarthritis; individual response varies.
Turmeric/curcumin: with moderate clinical support, with magnitudes comparable to some NSAIDs in symptomatic osteoarthritis, with a better gastrointestinal tolerability profile. Formulations with piperine or phytosomes improve bioavailability.
Boswellia serrata: well supported in osteoarthritis, especially standardized formulations.
Hydrolyzed collagen (10 g/day): growing clinical support for improving joint markers and pain.
Oral hyaluronic acid (80-200 mg/day): modest support.
Omega-3 EPA/DHA: adjunctive systemic anti-inflammatory effects.
MSM (methylsulfonylmethane): modest support, especially combined with glucosamine.
SAMe (S-adenosylmethionine) (1,200 mg/day): clinical support comparable to NSAIDs.
PEA (palmitoylethanolamide) + luteolin: with growing support for chronic joint pain.
Vitamin D: subclinical deficiencies are common and associated with worse symptoms.
For moderate-to-severe osteoarthritis with pain refractory to conservative treatment, intra-articular injections may play a role: - Corticosteroids: rapid and potent effect but limited in duration and with potential damage with frequent repeated use. - Hyaluronic acid (viscosupplementation): supported in rheumatology guidelines. - PRP (platelet-rich plasma): with growing support, especially in mild-to-moderate osteoarthritis.
Significant and persistent joint pain, joint effusion, deformity, major functional limitation, or suspected inflammatory arthritis (prolonged morning stiffness, involvement of several symmetrical joints, systemic symptoms) require medical evaluation.
Osteoarthritis is best managed with a comprehensive approach: a healthy weight, regular adapted exercise, physical therapy, supplements with support (turmeric, boswellia, collagen, omega-3) depending on individual response, adequate analgesia when appropriate, and more aggressive interventions (injections, surgery) when conservative ones are not enough; supplements are useful but modest in magnitude and do not replace structural interventions.
