What Actually Works for Joint Pain?

Glucosamine dominated the joint supplement market for decades. Turns out, it barely works. Here's what the research actually supports.

TL;DR

Best evidence: Collagen peptides (10g), Omega-3 (anti-inflammatory), Curcumin (with piperine). Moderate evidence: UC-II collagen (40mg), Boswellia. Limited/no evidence: Glucosamine (surprisingly), Chondroitin (marginal at best).

A

Strong Evidence

Collagen Peptides
10g daily8 studies

Reduces activity-related joint pain in multiple studies

12 weeks

Note: Specifically for activity-related pain, not arthritis cure

Omega-3 (EPA/DHA)
2-3g EPA+DHA daily15 studies

Reduces inflammation, may reduce need for NSAIDs

8-12 weeks

Note: Works through anti-inflammatory mechanism

Curcumin
500-1000mg with piperine12 studies

Anti-inflammatory comparable to some medications

4-8 weeks

Note: Must have piperine or be enhanced form for absorption

B

Moderate Evidence

UC-II Collagen
40mg daily5 studies

Undenatured type II collagen, works differently than peptides

8-12 weeks

Note: Lower dose than peptides, different mechanism

Boswellia
300-500mg daily6 studies

Anti-inflammatory, may help OA symptoms

4-8 weeks

Note: Look for AKBA-standardized extracts

C

Weak/Mixed Evidence

Glucosamine
1500mg daily25 studies

Large studies show minimal to no benefit

12 weeks

Note: The GAIT trial was disappointing. Decades of hype, weak results.

Chondroitin
800-1200mg daily18 studies

Marginal benefits in some studies, not others

12 weeks

Note: Often combined with glucosamine, both weak

Real Talk

Glucosamine and chondroitin were the go-to for decades. Then good studies came out showing they barely beat placebo. Collagen and anti-inflammatories (omega-3, curcumin) have better evidence now. The joint supplement world has evolved.

What Else Actually Helps

  • Movement. joints need motion to stay healthy
  • Weight management. every pound is 4 pounds of knee pressure
  • Strength training. muscles support joints
  • Physical therapy. often more effective than supplements

The Bottom Line

Skip glucosamine. Try collagen peptides (10g) or UC-II (40mg) for 3 months. Add omega-3 or curcumin for inflammation. Manage expectations. supplements support, not cure.
