Top picks by evidence
- Moderate evidence4 studies
Across 4 studies, all reported beneficial effects of Black Cumin (Nigella sativa) supplementation on reducing tumor necrosis factor-alpha (TNF-α). Two high-quality meta-analyses found moderate effect sizes, and one umbrella meta-analysis reported a large effect. The only study reporting dose used a range of 200–4600 mg/day over 7 days, but most studies did not specify dose or duration. Effects were observed in general populations and those with metabolic syndrome.
- Moderate evidence5 studies
Across 5 studies, 3 reported beneficial effects (small to moderate magnitude) of vitamin D supplementation on reducing tumor necrosis factor alpha (TNF-α) levels, while 2 found neutral effects. The beneficial findings come from systematic reviews and meta-analyses in populations including depression patients, overweight/obese individuals, and those with chronic pruritus. Doses ranged from 1000 to 5000 IU/day where reported, but most studies did not specify dose or duration.

Across 3 studies, all reported beneficial small-sized effects of L-carnitine supplementation on reducing tumor necrosis factor alpha (TNF-α). Effects were typically observed at 8 weeks (median study duration: 56 days). The most-studied population was adults, with specific evidence from a clinical trial in obese female patients.

- ModerateSaffronAcross 3 studies, all reported beneficial small-to-moderate effects of saffron supplementation on reducing tumor necrosis factor alpha (TNF-α), with all 3 reaching statistical significance. The most studied dose was 100–200 mg/day, and effects were observed in clinical populations including people with type 2 diabetes and ICU sepsis patients. The median study duration was 46 days, but effects were seen as early as 7 days and as late as 84 days. · Dose: 100-200 mg/day3 beneficial3 studies
- LowPropolisAcross 3 studies, all reported beneficial effects of propolis on reducing tumor necrosis factor alpha (TNF-α), with effect sizes ranging from small to large. The strongest evidence comes from a 2025 systematic review and meta-analysis showing a moderate, statistically significant reduction (WMD: -1.15; 95%CI: -1.75, -0.55; p < 0.001). Effects were observed in general adult populations and in patients with Type 2 diabetes, but dose ranges and study durations were not consistently reported.3 beneficial3 studies
- LowVitamin CAcross 5 studies, 2 reported beneficial moderate-sized effects of Vitamin C on reducing tumor necrosis factor-alpha (TNF-α), while 3 studies found neutral effects. The predominant effect size is mixed, as only a minority of studies showed benefit. The median study duration was 42 days, and the most-studied dose range was 250-1000 mg/day, primarily in clinical populations (e.g., septic shock patients, hemodialysis patients, older women with sarcopenia). · Dose: 250-1000 mg/day2 beneficial3 neutral5 studies
- LowN-Acetyl CysteineAcross 5 studies, 1 reported a beneficial small effect of N-acetyl cysteine (NAC) on reducing tumor necrosis factor alpha (TNF-α), while 4 found neutral results. The only beneficial effect was observed in a small RCT (n=45) of patients with nonalcoholic steatohepatitis (NASH) at a dose of 1200 mg twice daily for 26 weeks, showing a 9.64% reduction in TNF-α (P < 0.05). Most studies were in clinical populations and the median study duration was 84 days (12 weeks), but the overall evidence does not support a consistent effect. · Dose: 1200 mg twice daily1 beneficial4 neutral5 studies
- LowWhey ProteinAcross 4 studies, 1 reported a beneficial small effect of whey protein on reducing tumor necrosis factor alpha (TNF-α), while 3 found neutral results. The single positive study (25 g/day for 90 days) reached statistical significance in older adults, but the overall evidence base is limited and inconsistent. Effects were predominantly neutral, with no clear convergence on dose or population given the mixed findings.1 beneficial3 neutral4 studies
- LowTurmericAcross 3 randomized controlled trials, 1 study found a moderate beneficial effect of a turmeric (Curcuma longa) and Boswellia serrata combination on TNF-α reduction in chronic low back pain patients after 90 days, while 2 studies reported no significant effect in athletes and knee osteoarthritis patients. The overall effect direction is neutral with mixed effect sizes (small to moderate). Median study duration was 84 days.1 beneficial2 neutral3 studies
- LowVitamin EAcross 3 randomized controlled trials, 1 found a small beneficial effect of vitamin E on reducing tumor necrosis factor-alpha (TNF-α), while 2 found no significant effect. The predominant effect is neutral (no effect) or small when present, and effects were typically observed at 12 weeks (median study duration 84 days). Most studies used doses in the range of 400–800 IU/day in clinical populations (NASH, hemodialysis, sarcopenia). · Dose: 400–800 IU/day1 beneficial2 neutral3 studies
