Flow stands out for its thoughtful use of key nutrients such as MegaNatural-BP® grape seed extract, olive leaf extract standardized to oleuropein, and CoQ10. I appreciate the focus on a multi-pathway approach that supports cardiovascular wellness through antioxidant activity, vascular function, and energy production. Flow is a well-constructed natural option that I would recommend to individuals looking to support heart health as part of a consistent, healthy lifestyle."

- CircuShield™ Polyphenol Blend:
Specially formulated with clinically dosed natural ingredients that work together to support healthy blood pressure, circulation, and antioxidant defense:
MegaNatural-BP® Grape Seed Extract – 300mg per day (2 capsules):
Sustainably cultivated in California and containing an industry-leading concentration of antioxidant polyphenols.
Olive Leaf Extract – 800mg per day (2 capsules):
Contains over 20% of Oleuropein, the key organic compound responsible for cardiovascular benefits.
- CoQ10 – 200mg per day (2 capsules):
A natural vitamin-like antioxidant, CoQ10 supports cellular energy production in the heart and muscle tissues.
Flow’s doctor-endorsed, triple-action formula helps maintain healthy blood pressure and critical cardiovascular functions that decline as you age:
1. Healthy Circulation: Smooth blood flow is crucial for healthy blood pressure and the delivery of nutrients and oxygen throughout your body. CircuShield™ Polyphenol Blend supports wider and more flexible blood vessels, so your heart doesn't have to work as hard to do its job.
2. Antioxidant Defense: Flow contains a high concentration of powerful antioxidants that protects your body and cardiovascular system from harmful free radicals. Free radicals can damage healthy cells and tissues, especially when you face everyday stressors such as poor sleep or diet, and physical or mental stress.
3. Heart-Healthy Cellular Energy: CoQ10 produced naturally by your body tends to decline with age and medications such as statins. Flow’s clinical dose of CoQ10 helps your cells turn nutrients into usable energy for the heart that it needs to keep pace with your life.
To help you get optimal results from Flow™, every subscription also includes The Heartheris Complete Blood Pressure System, a $195 collection of 5 expert guides designed to help you build a stronger, holistic foundation for healthy blood pressure after 40.
Covering nutrition, exercise, sleep and recovery, stress management, and healthy weight & blood pressure habits, the system gives you practical, evidence-backed tools to support your cardiovascular wellness beyond supplementation alone. It’s emailed to you with your first order, and active subscribers receive complimentary lifetime updates whenever new content is added.
Take 1 capsule twice daily with meals.
The most important factor is consistency. If taking 2 capsules once a day with a meal fits your daily routine better, that is perfectly fine and still provides robust daily support.
For optimal results, we recommend taking Flow™ consistently, paired with a heart-healthy lifestyle with balanced eating, sleep and exercise habits.

Frequently Asked Questions
Your cardiovascular system is your body's engine, powering everything from movement to memory.
Yet, according to the American Heart Association, 48.6% of US adults (127.9 million) have some form of cardiovascular disease.
The prevalence of high blood pressure climbs from 23% in adults aged 18–39, to 53% in those aged 40–59, and up to 72% in adults aged 60 and over, based on US surveillance data.
With heart disease being the leading cause of death in the US and the risk of high blood pressure increasing significantly with age, proactively supporting your heart health is the foundation of your lifespan and healthspan. It pays dividends in every part of your life, helping you feel more energetic and capable, and to live better for longer.
Flow™ offers daily support for your cardiovascular system. Key benefits include:
• Supports Healthy Blood Pressure: Helps maintain blood pressure already in the normal range.
• Promotes Smooth Blood Flow: Supports healthy circulation, ensuring oxygen and vital nutrients are delivered effectively throughout your body.
• Enhances Cellular Energy: Fuels your heart and muscles for better stamina and performance.
• Aids Active Living: Supports exercise performance and recovery.
• Provides Potent Antioxidant Defense: Helps protect your cardiovascular system from daily stressors and free radical damage to support healthy aging.
Flow™ is ideal for any adult who wants to proactively support their long-term cardiovascular health. It is especially beneficial for those looking to support healthy blood pressure, energy and stamina for a busy life, and feel more capable during physical activities.
Absolutely. Flow™ is designed for proactive, daily support to help maintain healthy blood pressure already within the normal range. It works by nourishing the core pillars of your cardiovascular system, like healthy circulation and antioxidant defense, which is important for any adult looking to support long-term wellness.
Flow™ is designed for steady, long-term support. While individual results vary, most customers notice steady support with consistent daily use—typically within a few weeks, with more noticeable benefits like steadier energy, vascular function support and exercise tolerance building over time.
Yes, Flow™ is specifically formulated for safe, continuous daily use. Its ingredients provide steady, ongoing support for your cardiovascular system, making consistency key to maintaining long-term benefits.
Flow™ features a science-backed formula with three powerful ingredients at clinically effective doses to support your cardiovascular health and blood pressure.
Flow includes our CircuShield™ Polyphenol Blend, a synergistic blend that contains Grape Seed Extract and Olive Leaf Extract to support healthy blood flow and antioxidant defense.
Each daily serving (1 capsule twice a day) contains:
• CircuShield™ Polyphenol Blend — 1,100 mg:
MegaNatural-BP® Grape Seed Extract (300 mg): A clinically studied extract shown to support healthy blood pressure and circulation. Made from 100% sustainably cultivated California red and white wine grapes, it contains an industry-leading concentration of polyphenols (≥90%), the powerful antioxidants responsible for its cardiovascular benefits.
Olive (Olea europaea) Leaf Extract (800 mg): A potent botanical extract that supports vascular relaxation and provides robust antioxidant effects. Standardized to >20% Oleuropein, the key active compound responsible for its cardiovascular benefits, including supporting healthy blood vessels and blood pressure.
• Coenzyme Q10 (200 mg): A vital antioxidant that fuels cellular energy production in the heart and muscles. Your body's natural production of CoQ10 decreases with age and can also be depleted by certain medications like statins. Replenishing CoQ10 supports your daily energy, and helps protect your cells and tissues from free radical damage.
Flow™ stands apart with its:
• Synergistic Triple-Action Formula: Combines three science-backed ingredients that work together across three key pathways—Healthy Circulation, Antioxidant Defense, and Cellular Energy—for more comprehensive results.
• Clinically Effective Doses: We don’t believe in “window dressing”. Every ingredient is included at a clinically effective dose shown in studies to provide real benefits.
• Clean, Sugar-Free Formulation: Contains no sugar, artificial sweeteners or oils, unlike many gummies or chews that add unnecessary calories and carbohydrates.
• Standardized for Potency: We use premium, standardized ingredients like MegaNatural-BP® Grape Seed Extract to ensure you get a potent and consistent dose in every capsule.
Flow's Triple-Action formula provides comprehensive cardiovascular support by targeting three core pillars of heart health and healthy blood pressure. Our bodies change as we age, and the formula helps maintain critical functions that support long-term health and vitality.
1. Healthy Circulation: The CircuShield™ Polyphenol Blend with Grape Seed and Olive Leaf extracts helps your blood vessels relax, widen and stay flexible, promoting smooth blood flow.
2. Antioxidant Defense: Powerful antioxidants help protect your cells and tissues from the harmful effects of free radicals.
3. Cellular Energy: A clinical dose of CoQ10 supports energy production in your heart, one of the hardest-working muscles in your body.
For steady daily support, we recommend taking 1 capsule twice daily with meals.
The most important factor is consistency. If taking 2 capsules once a day with a meal (preferably your largest meal) fits your daily routine better, that is perfectly fine and still provides robust daily support.
Taking Flow™ with food, especially healthy fats (like avocado, nuts, seeds, olive oil, fatty fish, dairy / yogurt, or eggs), helps ensure the best absorption and results.
Yes, supporting healthy Nitric Oxide (NO) production is a key mechanism of Flow™.
Nitric Oxide is a vital signaling molecule your body produces naturally. Its primary role is to help the lining of your blood vessels (the endothelium) signal the vessels to relax and widen, a process called vasodilation. This is crucial for maintaining smooth, healthy blood flow and blood pressure.
The potent polyphenols in MegaNatural-BP® Grape Seed Extract have been shown to specifically help the endothelium produce more NO, which supports vascular flexibility and optimal circulation.
Flow™ is formulated using clinically studied ingredients at safe, well-tolerated dosages to support your well-being. Most individuals can take it without any issues when used as directed.
In the unlikely event that you experience discomfort or an adverse reaction, please discontinue use immediately and seek medical attention. Your health is our priority, and we also encourage you to share your experience with us, so we can continue to uphold the highest standards of product quality and customer experience.
No, Flow™ is completely stimulant-free and caffeine-free. It is designed to provide gentle, sustained support for your energy and cardiovascular health without the jitters or crashes associated with stimulants.
Yes, Flow™ is 100% vegan and formulated to be free from common allergens, making it suitable for many individuals with dietary sensitivities. It is non-GMO, gluten-free, soy-free, and dairy-free.
As with any supplement, if you are currently taking any medications, especially those related to blood pressure or blood thinning, it is always best to consult with your healthcare practitioner before use.
Your healthcare practitioner understands your unique health profile and can assess potential considerations to help you make an informed and safe decision that aligns with your overall health goals.
