Best Supplements for Reduced Pain
Ranked by research evidence. Compare 65 supplements across 114 papers from the biomedical literature, with effect direction, evidence strength, and dose range for each.
Top picks by evidence
- High evidence14 studies
Across 14 studies, 9 reported beneficial effects of turmeric/curcumin on pain reduction, with 5 studies finding no significant benefit (neutral). The predominant effect size was moderate. Evidence comes primarily from clinical populations with osteoarthritis, rheumatoid arthritis, chronic lower back pain, and oral inflammatory conditions, with a median study duration of 90 days suggesting benefits are observed with longer-term use. Doses varied widely, but when reported, ranged from 170 mg to 600 mg per day of curcuminoid extracts, often in combination with other agents.
- High evidence5 studies
Across 5 studies, all reported beneficial effects of Acetyl-Carnitine on pain reduction, with effect sizes ranging from small to moderate (predominantly moderate). The most-studied dose range was 1000–1500 mg/day, and effects were observed in clinical populations with neuropathic pain conditions (e.g., diabetic peripheral neuropathy, sciatica, carpal tunnel syndrome, fibromyalgia). Median study duration was 45 days, suggesting effects may appear within a few weeks.
Dose: 1000–1500 mg/day - 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.
Top combinations for Reduced Pain
most supplement research is combination research- Moderate evidence
Across 3 studies, all reported beneficial effects of the combination of vitamin E and vitamin C on pain reduction, with effect sizes ranging from small to moderate (predominantly small). The median study duration was 60 days. The combination shows similar effects to vitamin E or vitamin C alone based on solo syntheses, but all studies tested the combination as part of a multi-ingredient formulation, precluding isolation of the specific contribution of these two vitamins.
- HighTurmericAcross 14 studies, 9 reported beneficial effects of turmeric/curcumin on pain reduction, with 5 studies finding no significant benefit (neutral). The predominant effect size was moderate.

- LowVitamin DAcross 6 studies, 3 reported beneficial effects (predominantly small in magnitude) and 3 found neutral effects. The evidence is mixed: higher-quality meta-analyses show no significant benefit for pain, while lower-quality studies suggest small improvements in specific clinical populations such as sciatica (combined with other supplements) and rheumatic diseases. No consistent dose or form emerged; only one study specified a dose of 800 IU/day, and median study duration was 30 days (reported in only 1 study).3 beneficial3 neutral6 studies
- LowVitamin EAcross 4 studies, 3 reported beneficial effects on pain reduction, but the highest-quality evidence (a meta-analysis of 52 references in knee OA patients) found no significant effect. Effect sizes were mixed (small to moderate) among beneficial studies. The median study duration was 60 days (from one study). Most studies were conducted in clinical populations with osteoarthritis, fibromyalgia, carpal tunnel syndrome, or oral mucosal diseases.3 beneficial1 neutral4 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
- 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
