Top picks by evidence

  • Moderate evidence8 studies

    Across 8 studies, 5 reported beneficial effects (4 statistically significant) and 3 reported neutral effects, with no harmful findings. The predominant effect size is small to moderate, with the most robust evidence coming from RCTs showing moderate effects in clinical populations (e.g., colorectal cancer patients, overweight/obese adults). Doses ranged from 200 IU/day to personalized loading doses, and the median study duration was 56 days, indicating effects typically observed at 8–12 weeks.

    Dose: 200–5000 IU/day (most consistent evidence near 2000 IU/day or personalized loading doses)

  • LowTurmericAcross 4 studies, 2 reported beneficial moderate-sized effects on reducing interleukin-6 (IL-6) levels, while 2 found neutral results with small or no effect. The predominant effect direction is beneficial, but effect sizes were mixed (moderate for beneficial studies vs. small for neutral studies). The most studied population was clinical (e.g., chronic lower back pain, knee osteoarthritis, metabolic syndrome), with a median study duration of 84 days, suggesting effects are typically observed at 8-12 weeks.2 beneficial2 neutral4 studies
  • LowPropolisAcross 4 studies, 2 reported beneficial effects on interleukin-6 levels, while 2 found no significant effect; the predominant effect size was mixed (small to large). The evidence base includes meta-analyses in clinical populations with type 2 diabetes, but no consistent dose range or duration was reported. Overall, propolis shows mixed evidence for reducing IL-6, with findings varying by study design and population.2 beneficial2 neutral4 studies

  • LowWhey ProteinAcross 3 studies, 1 reported a beneficial small-sized effect on reducing interleukin-6 levels, while 2 found neutral effects (no significant reduction). The sole beneficial study was a large meta-analysis in older adults with sarcopenia (n=1154), which reported a significant small effect. The median study duration was 56 days (based on 1 study), though limited duration data prevents strong conclusions about timing. The most studied population was clinical (sarcopenia, frailty, hemodialysis patients).1 beneficial2 neutral3 studies
