Quick answer: Follow your label. With 30 servings in a 30 mL bottle, a serving is likely about one dropper (1 mL) a day, under the tongue or in water. Shake well and take it in the morning, since the reported blend includes caffeine sources. Check with your doctor first if you take heart or blood pressure medicine.

Talk to your doctor or pharmacist before using CardioFlush if:
- You take blood pressure medicine, nitrates (such as nitroglycerin) or erectile dysfunction pills. L-arginine may lower blood pressure too far.

- You take blood thinners such as warfarin or daily aspirin; grape seed and ginseng may add to bleeding risk.
- You take diabetes medicine; Gymnema and ginseng may lower blood sugar.
- You have kidney or liver disease, low potassium, or a recent heart attack or stroke.
- You are pregnant, breastfeeding or under 18.
When to stop: stop and get advice if you feel dizzy, jittery, have palpitations, headaches or swelling. Call emergency services for chest pain, shortness of breath or sudden weakness.
