Nutrients connected to Joint Support

A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.

• UC-II (Undenatured Type II Collagen)Preliminary or mixed

  Trials in knee osteoarthritis and exercise-related knee pain reported better symptom and function scores with 40 mg a day of UC-II; small, short, product-specific and mostly industry-linked.

• Joint Formulas (Glucosamine, Chondroitin, MSM, Turmeric)Preliminary or mixed

  Sold for joint comfort; trials show mixed results and small average effects.

• Curcumin (turmeric supplements)Preliminary or mixed

  Early reviews report positive results for knee osteoarthritis pain and stiffness; NCCIH says better studies are needed and the evidence is not conclusive.

• TurmericPreliminary or mixed

  Early studies of turmeric or curcumin taken by mouth report some improvement in knee osteoarthritis pain and stiffness, but NIH says better-quality studies are needed. A review of supplement trials rated the overall evidence very low quality.

• ArnicaPreliminary or mixed

  Arnica gel was not worse than ibuprofen gel in one 21-day hand osteoarthritis trial; the evidence is a single study and the EU accepts skin use mainly on traditional grounds.

• BoswelliaPreliminary or mixed

  Some trials and pooled analyses of oral boswellia extracts in osteoarthritis report less pain and stiffness, but studies are small, one 2024 analysis found no significant overall effect, and NCCIH says evidence is not enough to call it useful.

• Devil's clawPreliminary or mixed

  Some short-term trials of standardized root extracts found less joint or back pain than placebo, but the Cochrane review rated this evidence low quality and the EU committee accepted it only as traditional use.

• Nirgundi (Chinese chaste tree)Preliminary or mixed

  Used traditionally for joint pain. Only a branded nirgundi and ginger blend has been tested in small, company-linked human trials; nirgundi alone has no human trials.

• TurmericPreliminary or mixed

  Early meta-analyses of oral turmeric or curcumin are positive for knee osteoarthritis; better research is needed. Not shown for food amounts.

• Dead Sea MudPreliminary or mixed

  Mud packs may ease knee osteoarthritis pain in some analyses; results are mixed and not specific to Dead Sea mud.

• Peloids and Mud TherapyPreliminary or mixed

  Warm mud packs and baths have reduced knee osteoarthritis pain in several analyses; quality varies.

• Balneotherapy (Spa Therapy)Preliminary or mixed

  Osteoarthritis evidence promising but weak in quality.

• Sulfur (Sulphur) BathsPreliminary or mixed

  Spa baths in mineral water may ease arthritis pain in short-term trials; sulfur baths alone showed no clear difference in the Cochrane review.

• Collagen Peptides (Hydrolyzed Collagen)Preliminary or mixed

  Small-to-moderate improvements in knee pain and function scores versus placebo in a 35-trial meta-analysis. Cartilage repair was not measured.

• Bovine Collagen (Types I and III)Preliminary or mixed

  One 13-week trial of pork-skin and bovine-bone peptides and a meta-analysis of four high-risk-of-bias trials reported less knee osteoarthritis pain; findings are limited.

• Chicken Collagen (Type II)Preliminary or mixed

  A chicken-derived undenatured type II collagen (UC-II) lowered knee symptom scores in several small trials, but one larger 2026 trial found no advantage over placebo. Results do not transfer to other collagen products.

• Eggshell Membrane (NEM)Preliminary or mixed

  A 2024 meta-analysis of five small placebo-controlled trials found less knee pain and better function; individual trials were mixed and several link to the maker.

• Fish oilPreliminary or mixed

  A 2022 review of 30 studies in rheumatoid arthritis suggested omega-3-rich foods may improve pain and joint swelling; another 2021 review found lower pain but rated the evidence low.

• Krill oilPreliminary or mixed

  Two small meta-analyses of knee osteoarthritis disagree on pain; evidence is mixed.

• Omega-3 fatty acids (ALA, EPA and DHA)Preliminary or mixed

  NCCIH says omega-3-rich diets may improve pain and joint symptoms in rheumatoid arthritis, but evidence is low quality.

• Willow barkPreliminary or mixed

  Traditional use for minor joint pain; a trial for osteoarthritis was negative, so evidence is mixed.

• ComfreyPreliminary or mixed

  Only for specific skin gels in knee osteoarthritis pain, one trial; limited evidence.

• Sweet wormwood (Artemisia annua)Preliminary or mixed

  One small pilot placebo-controlled trial of a specific low-dose formulation reported less osteoarthritis pain; unconfirmed.

• HaritakiPreliminary or mixed

  One 84-day trial of a standardized extract improved knee comfort with activity in overweight adults.

• Angelica pubescens (du huo)Preliminary or mixed

  Used traditionally for joint pain. Evidence for the root alone is lacking; one formula meta-analysis (ankylosing spondylitis) was positive with limits.

• Bitter kolaPreliminary or mixed

  One small randomized trial (2008) found less knee-osteoarthritis pain than placebo and a result similar to naproxen and celecoxib. It was a single small trial with many dropouts, so the evidence is limited.

• BoragePreliminary or mixed

  Cochrane found moderate evidence that GLA oils, including borage seed oil, give some relief in rheumatoid arthritis. Few trials; applies to the oil only.

• PineapplePreliminary or mixed

  Based on bromelain pill-combination trial in knee osteoarthritis; limited and not about the fruit.

• Thunder god vinePreliminary or mixed

  Oral extracts may help some rheumatoid arthritis symptoms per NCCIH, but evidence quality is low to moderate and serious toxicity is documented.

• CabbagePreliminary or mixed

  Leaf wraps showed symptom relief in one small knee osteoarthritis trial; limited evidence.

• Ground elder (goutweed)Lab or animal research only

  Traditionally used for joints, with a lab COX-1 finding. No human trials were found, so benefit in people is unproven.

• Nettle TeaPreliminary or mixed

  The EU committee accepts nettle leaf for relief of minor joint pain on the basis of long use. No trial of the tea was found.

• Rose Hip TeaPreliminary or mixed

  Trials of a rose hip powder (not tea) found less osteoarthritis pain than placebo; manufacturer-supported and sparse.

• Multi-Collagen Blends (Types I, II, III, V, X)Preliminary or mixed

  One small trial of a type I, II and III product reported less pain than placebo in meniscus problems; many function tests did not differ.
