What is known
Each outcome with its grade (how strong the evidence is, A to D), the size of the effect where the entry records one, and how often studies agree.
- Curcumin (Turmeric)Evidence grade B
A genuine anti-inflammatory for joints and mood — if you solve its terrible absorption; ignore the cancer-cure hype.
Unclearmixed
- Collagen PeptidesEvidence grade B
Real, if modest, evidence for tendon, joint, and skin outcomes when taken with vitamin C before loading — better than its hype suggested a decade ago.
Unclearmixed
- BoswelliaEvidence grade B
An anti-inflammatory resin with some of the better osteoarthritis-pain data among botanicals.
Unclearmixed
- UC-II (Undenatured Collagen II)Evidence grade B
A tiny-dose collagen that works by immune tolerance, not building blocks — decent joint-pain evidence.
Unclearmixed
- SAM-eEvidence grade B
A methyl donor with genuine antidepressant and osteoarthritis evidence — effective, pricey, and serotonergic.
Unclearmixed
- GlucosamineEvidence grade C
A joint mainstay with genuinely divided evidence — modest benefit at best, and a surprising cardiovascular-mortality observational signal in its favor.
Unclearmixed
- ChondroitinEvidence grade C
Glucosamine's usual partner — similarly modest and contested for osteoarthritis.
Unclearmixed
- MSMEvidence grade C
A sulfur donor with small joint-pain and exercise-recovery signals, often bundled into joint formulas.
Unclearmixed
- Hyaluronic Acid (Oral)Evidence grade C
An oral skin-and-joint supplement with modest hydration and knee-comfort signals.
Unclearmixed
- Cat's ClawEvidence grade C
An Amazonian anti-inflammatory bark with early joint-pain evidence and immune-modulating caveats.
Unclearmixed
- Eggshell Membrane (NEM)Evidence grade C
A collagen/glycosaminoglycan joint supplement with modest, mostly industry-funded evidence.
Unclearmixed
- Cissus QuadrangularisEvidence grade C
An Ayurvedic bone-and-joint herb with early evidence for fracture healing and joint pain.

What is uncertain
Read off the same rows as above. Nothing here is added that the entry does not itself record.
- Thin evidence: Glucosamine (grade C); Chondroitin (grade C); MSM (grade C); Hyaluronic Acid (Oral) (grade C); Cat's Claw (grade C); Eggshell Membrane (NEM) (grade C); Cissus Quadrangularis (grade C).
- Studies disagree: Curcumin (Turmeric) (mixed agreement); Collagen Peptides (mixed agreement); Boswellia (mixed agreement); UC-II (Undenatured Collagen II) (mixed agreement); SAM-e (mixed agreement).
