- Anticoagulant and antiplatelet therapies: Mild blood-thinning effects could compound warfarin or supplements like Garlic, increasing bleeding risk—monitor INR.
- Lithium and renal-excreted medications: Diuretic action may alter clearance; if you take lithium, check serum levels regularly.

Studies
These studies provide scientific insights into Green Coffee Bean Extract benefits:
A 2011 meta-analysis of five RCTs found green coffee bean extract (400 mg chlorogenic acid/day) yields modest weight loss (MD = –2.47 kg; 95% CI: –4.23 to –0.72; P = 0.005) versus placebo, but evidence quality was low.
A 2012 double-blind trial in 30 overweight adults reported no significant difference in body weight or fat mass after 12 weeks of 200 mg green coffee extract versus placebo (ns).
A 2013 randomized trial found 400 mg green coffee blend for 8 weeks did not alter fasting glucose or insulin sensitivity versus placebo (ns).
Despite marketed antioxidant benefits, no RCTs have evaluated green coffee bean extract for cardiovascular or cognitive endpoints in humans.
