Internal Medicine

Daily consumption of cocoa flavanols has been shown to improve blood flow and lower blood pressure, according to multiple studies. While the optimal dose varies by individual, research consistently links regular intake—typically 200–600 mg per day—to measurable cardiovascular benefits, including enhanced endothelial function and reduced hypertension risk.

However, blood pressure changes, poor circulation, or related symptoms can stem from many underlying causes beyond diet. If you're noticing symptoms like fatigue, headaches, dizziness, or chest discomfort, it's worth understanding what may be driving them before making assumptions.
