|---|---|---|---|---|
| Omega-3 (EPA/DHA) | High-EPA fish oil | 2-3g/day | Inflammation, stiffness | Strong |
| Glucosamine | Sulfate (not HCl) | 1500mg/day | Cartilage repair | Moderate |
| Chondroitin | Chondroitin sulfate | 800-1200mg/day | Cartilage protection | Moderate |
| Turmeric (Curcumin) | With piperine/phospholipid | 500-1000mg/day | Inflammation, pain | Strong |

1. Omega-3 (EPA/DHA) — Best Overall for Inflammation
Why it works: EPA reduces inflammatory prostaglandins and leukotrienes that drive joint inflammation.¹
The research:
- A 2017 meta-analysis of 42 RCTs found omega-3s significantly reduced joint pain, stiffness, and NSAID use in arthritis patients.²
- A 2019 RCT found 2.5g EPA+DHA/day reduced rheumatoid arthritis disease activity by 30%.³
Dosing: 2-3g combined EPA+DHA per day.
Our pick: Nordic Naturals ProOmega
2. Turmeric (Curcumin) — Best Natural Anti-Inflammatory
Why it works: Curcumin inhibits NF-κB, COX-2, and LOX — the same inflammatory pathways targeted by NSAIDs.⁴
The research:
- A 2016 meta-analysis of 8 RCTs found curcumin (1000mg/day) significantly reduced arthritis pain and inflammation.⁵
- A 2019 RCT found curcumin + piperine was as effective as diclofenac for knee osteoarthritis.⁶
Dosing: 500-1000mg/day of curcumin with piperine (black pepper) or phospholipid for absorption.
Our pick: Thurne Meriva Curcumin
3. Glucosamine Sulfate — Best for Cartilage Repair
Why it works: Glucosamine is a building block for cartilage glycosaminoglycans. Sulfate form is more effective than HCl.⁷
The research:
- A 2007 RCT (n=250) found 1500mg glucosamine sulfate for 2 years significantly reduced joint space narrowing vs placebo.⁸
- A 2018 meta-analysis confirmed benefits for osteoarthritis pain and function.⁹
Dosing: 1500mg glucosamine sulfate once daily.
Our pick: Doctor’s Best Glucosamine Sulfate
4. Collagen (Type II / UC-II) — Best for Immune-Mediated Arthritis
Why it works: Undenatured Type II collagen (UC-II) modulates the immune response against joint cartilage.¹⁰
The research:
- A 2016 RCT found 40mg UC-II/day for 180 days significantly improved WOMAC scores in knee osteoarthritis.¹¹
- A 2019 study found UC-II was more effective than glucosamine + chondroitin.¹²
Dosing: 40mg UC-II daily on an empty stomach.
Our pick: NOW UC-II
