CGA-7™ (Green Coffee Chlorogenic Acid Complex)

CGA-7 is a branded green coffee bean extract from Vidya Herbs standardized to 50% chlorogenic acids, used for weight, metabolic and lipid support. Green coffee chlorogenic acid has multiple meta-analyses behind it, though effects are modest.

Green coffee has much less caffeine than roasted coffee, but it is not caffeine-free, so very sensitive people may notice mild stimulation. The active is chlorogenic acid rather than caffeine.

CGA-7 is researched primarily for Weight Management, Metabolic Health, and Cardiovascular. Meta-analyses of green coffee chlorogenic acid report small reductions in body weight and BMI. CGA-7 is positioned on this evidence; honest framing: effects are modest and not a substitute for diet and activity.
