Ranked by research evidence. Compare 63 supplements across 103 papers from the biomedical literature, with effect direction, evidence strength, and dose range for each.
Top picks by evidence
- Moderate evidence13 studies
Across 13 studies, 9 reported beneficial effects of turmeric/curcumin on reducing pain, with effect sizes ranging from small to moderate. The predominant effect size is moderate, and benefit was most consistently observed in clinical populations with osteoarthritis, rheumatoid arthritis, and chronic lower back pain over a median study duration of 90 days. Doses varied widely, but a common regimen was 300–600 mg of curcumin extract once or twice daily.
Dose: 300-600 mg of curcumin extract once or twice daily - Moderate evidence8 studies
Across 8 studies, 6 reported beneficial effects of vitamin C on reducing pain, with effect sizes ranging from small to moderate. The median study duration was 60 days across the 3 studies reporting duration, suggesting effects may require several weeks of supplementation. The evidence is strongest for postoperative pain (e.g., dental surgery and hip arthroplasty), with some studies also showing benefit in fibromyalgia and carpal tunnel syndrome.
- Moderate evidence3 studies
Across 3 studies, all reported beneficial effects of vitamin E supplementation on pain reduction, with effect sizes ranging from small to moderate (predominantly small). The median study duration was 60 days. The evidence is limited to diverse clinical populations including fibromyalgia, carpal tunnel syndrome, and oral mucosal diseases, often in combination with other nutrients, making it difficult to isolate the specific effect of vitamin E alone.
Top combinations for Reduced Pain
most supplement research is combination research- Low evidence
Across 3 studies, all reported beneficial effects of the Vitamin E and Vitamin C combination on pain reduction, with effect sizes ranging from small to moderate and all findings statistically significant. Compared to Vitamin C alone (moderate evidence, small effect), the combination shows a similar directional benefit but the limited number of studies precludes a definitive comparison. The median study duration was 60 days (reported in 1 of 3 studies). No form data were reported for either substance.
- ModerateTurmericAcross 13 studies, 9 reported beneficial effects of turmeric/curcumin on reducing pain, with effect sizes ranging from small to moderate. The predominant effect size is moderate, and benefit was most consistently observed in clinical populations with osteoarthritis, rheumatoid arthritis, and chronic lower back pain over a median study duration of 90 days.

- LowVitamin DAcross 4 studies, 3 reported beneficial effects of vitamin D on pain reduction, with effect sizes ranging from small to moderate. The only study reporting a specific dose used 800 IU/day for 30 days in a clinical population with sciatica, and the median study duration was 30 days. Evidence is predominantly small in magnitude, with one moderate effect observed in a combination therapy context. · Dose: 800 IU/day3 beneficial1 neutral4 studies

- LowAcetyl-CarnitineAcross 3 studies, all reported beneficial effects of acetyl-carnitine on pain reduction, with effect sizes ranging from small to moderate. The evidence is preliminary and predominantly from clinical populations with sciatica or carpal tunnel syndrome, using doses around 1000 mg/day. Effects were observed over a median study duration of 45 days. · Dose: 600-1000 mg/day3 beneficial3 studies
- LowL-ArginineAcross 3 studies, 2 reported beneficial moderate-sized effects of L-arginine on reducing pain, while 1 found no significant benefit. Evidence primarily comes from clinical populations with sickle cell disease experiencing vaso-occlusive crises or patients with radiation-induced oral mucositis, with doses ranging from 100 mg/kg/dose three times daily to 5 g daily. The median study duration was 49 days (based on 1 study), but effects were observed within 1-7 weeks. · Dose: 100 mg/kg/dose three times daily or 5 g daily2 beneficial1 neutral3 studies
- LowAloe VeraAcross 3 studies, 2 reported beneficial effects (one small, one moderate) on pain reduction with aloe vera, while one meta-analysis found no significant difference. The evidence base is small and mixed, with effect sizes ranging from small to moderate. Studies focused on oral ulcer conditions (recurrent aphthous stomatitis and radiation-induced oral mucositis).2 beneficial1 neutral3 studies
