Methodology
Twelve-week randomised double-blind placebo-controlled trial of Korean red ginseng 2.25 g daily in adults with dysglycaemia, with HbA1c as primary outcome
Key Findings
HbA1c did not differ significantly from placebo, although plasma glucose and insulin indices showed small favourable changes.
Conclusions
Korean red ginseng did not improve HbA1c in a controlled trial despite minor glycaemic index changes.
Limitations
Modest sample; well-controlled baseline glycaemia limits room for improvement.
Supplements Studied
HbA1c did not differ significantly from placebo, although plasma glucose and insulin indices showed small favourable changes.
Outcomes Measured
HbA1c did not differ significantly from placebo, although plasma glucose and insulin indices showed small favourable changes.
