# Joint pain supplements have limits you need to know *Joint Pain Supplements — Joint Pain Treatment Gilbert* > Straight guidance on joint pain supplements and joint pain treatment Gilbert choices, including vitamins and product safety. This page tells you what joint pain supplements may do and how to try one safely. Some studies found a little relief for a short time. Other studies found no more relief than a look-alike pill with no active ingredient. No bottle has given lasting relief to everyone. If you try one, name the change you hope to feel and choose a date to stop. Check the cost and safety before you begin. ## Glucosamine and chondroitin are joint-pill ingredients that seldom help much Studies compared these pills with look-alike pills that had no active ingredient. The extra relief from glucosamine or chondroitin was too small for many people to feel. The pills haven’t been shown to rebuild worn tissue. If you still want to try one, use only one product at a time. Pick a daily action, such as rising from a chair, and write down whether it gets easier. Keep meals, medicine and exercise much the same while you watch that action. ## A vitamin helps only when your body needs it Joint soreness alone does not prove that a vitamin is low. Your health history and a blood test can show whether your body lacks one. Replacing a vitamin may then help your health, though extra amounts may not help the joint. Vitamin D did not ease lasting knee soreness in a large group. That doesn’t mean the vitamin has no other health use. It means that group did not get knee relief from taking it. ## A doctor or pharmacist should check supplements with your medicines Products sold as natural can still cause trouble with your medicines. Some may raise bleeding risk or strain the kidneys. One bottle with several ingredients makes it harder to tell which one caused a side effect. Let a doctor or pharmacist review the bottle before you use it. Say what change you hope to feel and the date when you will stop if nothing improves. Lasting swelling or weakness can need medical care, so arrange an exam instead of trying another bottle. ## Sources 1. A meta-analysis of 20 dietary supplements across 69 randomised trials in hand, hip or knee osteoarthritis found that seven (collagen hydrolysate, passion fruit peel extract, Curcuma longa extract, Boswellia serrata extract, curcumin, pycnogenol and L-carnitine) showed large short-term effects on pain, and six more (undenatured type II collagen, avocado soybean unsaponifiables, methylsulfonylmethane, diacerein, glucosamine, chondroitin) showed statistically significant but clinically unclear effects. At MEDIUM term only green-lipped mussel extract and undenatured type II collagen retained clinically important effects, and NO supplement had a clinically important effect on pain at long term.

Within the VITAL trial - 25,871 US adults randomised in a 2-by-2 factorial design to vitamin D and/or marine omega-3 fatty acids - a subgroup of 1,398 participants with pre-existing chronic knee pain (mean age 67.7, 66% women, mean WOMAC pain 37 of 100) was followed for a mean of 5.3 years. WOMAC pain did not differ between active vitamin D and its placebo, or between active omega-3 and its placebo, at any time point, and the time-by-treatment interactions were not significant. Function and stiffness gave the same answer.

DOI: 10.1002/art.41416. 3. In a randomised, double-blind, placebo-controlled trial, 136 patients with hand osteoarthritis or psoriatic arthritis who still had moderate pain on existing therapy received synthetic cannabidiol 20-30 mg daily or placebo for 12 weeks. The between-group difference in pain intensity at 12 weeks was 0.23 mm on a 0-100 mm scale (95% CI -9.41 to 9.90; p=0.96). There were no significant effects on sleep quality, depression, anxiety or pain catastrophizing either.

A meta-analysis of 198 randomised osteoarthritis trials (16,364 patients in placebo groups, 1,167 in untreated control groups) found the placebo arm itself relieved pain with an effect size of 0.51 (95% CI 0.46-0.55), against 0.03 (95% CI -0.13 to 0.18) in untreated controls. Placebo also improved function and stiffness. The placebo effect was larger when the active treatment effect was larger, when baseline pain was higher, and - relevant to any injected treatment - when the placebo was delivered by injection rather than by mouth.

DOI: 10.1136/ard.2008.092015. 5. A BMJ network meta-analysis of 10 large trials in 3,803 patients found that compared with placebo the difference in pain intensity on a 10 cm visual analogue scale was -0.4 cm for glucosamine, -0.3 cm for chondroitin and -0.5 cm for the combination - none crossing the pre-specified minimal clinically important difference of -0.9 cm. Industry-independent trials showed smaller effects than commercially funded ones (P=0.02 for interaction).

A two-year randomized placebo-controlled trial in 146 participants with symptomatic knee OA raised serum 25-hydroxyvitamin D by a mean 16.1 ng/mL with cholecalciferol 2000 IU/day, testing whether vitamin D supplementation reduces symptom and structural progression of knee osteoarthritis.
