  • Very low evidence3 studies

    Across 3 studies, 1 found a small beneficial effect of black cumin (Nigella sativa) supplementation on lowering insulin levels, while 2 showed neutral results. The single beneficial study was an 8-week RCT in overweight/obese women using 2000 mg/day. The evidence base is very small, and the median study duration (56 days) is consistent with effects typically observed at 8 weeks.

    Dose: 2000 mg/day (reported in only 1 study)
