Frequently Asked Questions
About Flow
Q: What is Flow?
A: Flow is a targeted supplement from Natural Heart Doctor that combines two powerful enzymes—nattokinase and serrapeptase—to support healthy circulation, flexible blood vessels, and strong cardiovascular health.
Q: How does Flow work?
A: Flow helps your body naturally maintain smooth, healthy blood flow.
- Nattokinase supports normal clotting, helps break down arterial plaque, and promotes healthy carotid arteries.
- Serrapeptase reduces excess fibrin and inflammatory proteins, supporting vessel flexibility and resilience.
Together, they help protect against arterial damage, poor circulation, and the risks of heart attack and stroke.
Q: Who should consider taking Flow?
A: Flow may be especially helpful for people with:
- Family history of heart disease or stroke
- High blood pressure or cholesterol
- Circulation issues (heavy legs, swelling, cold extremities)
- Stiffness in arteries or early signs of vascular damage
Always consult your doctor before beginning any supplement program, especially if you are pregnant, nursing, or taking medication.
Q: How do I take Flow?
A: Take 1 capsule twice daily, away from food. We recommend keeping it on your nightstand: take one capsule first thing in the morning and one right before bed.
Q: When will I notice results?
A: Many people report feeling improvements in circulation, energy, and overall wellness within weeks. However, Flow works best as part of a long-term cardiovascular support plan. Consistency is key.
Q: Are there any side effects?
A: Flow is generally well-tolerated. Some individuals may experience mild digestive discomfort when starting. Because nattokinase supports normal clotting, consult your physician before use if you are taking blood-thinning medication or have a bleeding disorder.

Q: Where are Flow's ingredients sourced?
A: We source nattokinase and serrapeptase from trusted suppliers, ensuring purity and potency. Every batch is third-party tested for quality, safety, and effectiveness.
