- Moderate evidence5 studies
Across 5 studies, 3 reported beneficial effects of vitamin D supplementation on reducing tumor necrosis factor alpha (TNF-α), with effect sizes ranging from small to moderate. The most consistent evidence comes from systematic reviews and meta-analyses, including a large dose-response meta-analysis (962 participants) showing a small but statistically significant reduction in TNF-α. The median study duration was 56 days, suggesting effects are typically observed after 8 weeks of supplementation; the most-studied dose was up to 5,000 IU/day, and benefits were noted in populations including depressed patients and overweight/obese individuals.

Across 3 studies (all systematic reviews with meta-analyses), propolis supplementation consistently shows beneficial effects on reducing Tumor Necrosis Factor Alpha (TNF-α). Effect sizes range from small to large, with the highest-quality meta-analyses reporting moderate-to-large reductions (e.g., mean difference of -1.15 pg/mL; standardized mean difference of -1.42). The evidence is based on adult populations, including those with type 2 diabetes, but study durations and doses were not consistently reported.

Across all 3 studies, L-carnitine supplementation consistently reduced Tumor Necrosis Factor Alpha (TNF-α) with small effect sizes. One meta-analysis (n=3,255) and one randomized controlled trial (1,000 mg/day for 56 days) both reported significant reductions. The median study duration was 56 days, indicating effects are typically observed at 8 weeks.

- ModerateBlack CuminAcross all 3 studies (all meta-analyses), Black Cumin (Nigella sativa) supplementation consistently showed beneficial effects on reducing Tumor Necrosis Factor Alpha (TNF-α), with all 3 reporting statistically significant reductions. Effect sizes were predominantly moderate to large, and the strongest evidence (highest-rated study) used a dose range of 200 to 4600 mg/day over 7 days in a broad population of 5,026 participants, though limited duration data suggest effects may appear early. The evidence base is small and uniformly positive, raising concerns about publication bias. · Dose: 200 to 4600 mg/day3 beneficial3 studies
- LowVitamin CAcross 5 studies, 2 reported beneficial moderate-sized effects of vitamin C supplementation on reducing tumor necrosis factor-alpha (TNF-α), while 3 found neutral effects with predominantly small effect sizes. The evidence is mixed, with benefits observed primarily in acute clinical settings (e.g., septic shock), but not in chronic conditions such as hemodialysis or sarcopenia. The median study duration was 42 days, though the two significant studies had durations of 28 days (clinical septic shock) and an unreported duration; the most studied single dose was 1 g/day. · Dose: 1 g/day (single dose), though dose varied across studies (250 mg to 1000 mg/day or high-dose short courses).2 beneficial3 neutral5 studies
- LowN-Acetyl CysteineAcross 4 studies, only 1 reported a small beneficial effect of N-acetyl cysteine (NAC) on reducing tumor necrosis factor alpha (TNF-α), observed in patients with nonalcoholic steatohepatitis (NASH) at a dose of 1200 mg twice daily for 26 weeks; the remaining 3 studies (including a meta-analysis) found no significant effect. The median study duration was 119 days (approximately 17 weeks) among the 2 studies that reported duration. Overall, the evidence predominantly shows neutral effects.1 beneficial3 neutral4 studies
- LowVitamin EAcross 3 randomized controlled trials, Vitamin E supplementation showed mixed effects on tumor necrosis factor alpha (TNF-α) levels. One small-to-moderate quality study (2025) in NASH patients reported a small beneficial reduction of 9.64% (p<0.05) with 400 IU twice daily over 182 days, while two other RCTs in hemodialysis and sarcopenic older women found no significant effect at doses of 600 IU and 335 mg/d, respectively. Overall, the evidence is limited and mixed, with effects typically observed at 56–182 days. · Dose: 335–800 IU/day1 beneficial2 neutral3 studies
- LowTurmericAcross 3 randomized controlled trials, turmeric/curcumin supplementation showed 1 beneficial study with a moderate-sized significant reduction in TNF-α, while 2 studies reported neutral findings with small effect sizes. The median study duration was 84 days, suggesting effects may require at least 8-12 weeks to observe. Evidence is strongest for clinical populations (chronic lower back pain, knee osteoarthritis), with the most-studied dose being a daily curcumin extract (e.g., 300 mg CL20192). · Dose: 300 mg CL20192 once daily or 2g/day curcumin1 beneficial2 neutral3 studies
