My doctor was happy with my BP

"Glad I found Flow. At my latest checkup, my doctor was really happy with my BP numbers and told me to keep doing what I'm doing. I've got more energy lately too, which has been a great bonus."

Your Options

When Your Doctor Says Your Blood Pressure Is Too High, You Have 3 Options.

1. Prescription Medication

Works by directly overriding your body's mechanisms.

  • Common side effects include: Fatigue, dizziness, headaches, nausea, persistent dry cough
  • Doses often increase over time, and it's easy to end up on 2 prescriptions, then 3, or more

Most adults want to support their cardiovascular system proactively before medication becomes the only option left.

2. Generic Supplements

Blood pressure depends on a complex cardiovascular system, not one isolated mechanism. Yet many supplements rely on a single ingredient or inadequate amounts, leaving key pathways unaddressed.

The result? You feel no different, or end up dealing with unwanted side effects:

  • Beetroot: A study found that 1 in 15 participants supplementing with beetroot experienced headaches. Can also turn urine and stools red, and cause stomach upset or bloating.
  • Garlic: Often causes gas, body odor, lingering garlic breath, and abdominal discomfort
The Third Way

Flow™ by Heartheris

Strengthens and supports your entire cardiovascular system the way it was designed to work, by addressing all 3 key BP pathways.

  • Comprehensive blood pressure support: Combines 3 clinically studied ingredients at effective doses shown to support healthy blood pressure, circulation, artery protection, and heart-healthy energy.
  • Designed to build results over 90 days, and safe for long-term daily use to help maintain healthy BP naturally.
  • Reviewed and recommended by healthcare professionals. Made in the USA.

How Flow™ Works

Complete Blood Pressure Support Across All 3 Critical Pathways

Flow™ Triple-Action Blood Pressure Support System — Healthy Circulation, Antioxidant Protection, Cellular Energy
01

Healthy Blood Pressure and Free-Flowing Circulation

Flexible blood vessels support free-flowing circulation, delivering oxygen and nutrients throughout the body efficiently. That’s critical for healthy BP and better stamina to keep up with demanding days.

  • Flow™ boosts nitric oxide production to help blood vessels stay healthy and support healthy blood pressure.
02

Dual Antioxidant Protection

Blood vessels accumulate damage over time from oxidative stress, a key driver of rising BP. Increasing stress makes blood vessels stiffer and strains the cardiovascular system.

  • Flow™ delivers powerful antioxidants from Grape Seed + Olive Leaf that help protect your blood-vessel lining from oxidative stress and free-radical damage.
03

Heart-Healthy Cellular Energy

If your energy or stamina isn't what it used to be, CoQ10 levels may be the reason. CoQ10 declines naturally with age, and the heart is one of its biggest consumers.

  • Flow™ restores CoQ10 and supports the energy your heart needs, without relying on caffeine or stimulants.
Clinical Research

Decades of Clinical Evidence Behind Every Ingredient

Flow’s natural ingredients are backed by 49 peer-reviewed clinical trials and optimally dosed at research-aligned levels. Here’s what the studies found.

MegaNatural-BP® Grape Seed Extract
Clinical Study: 8-week randomized controlled trial with pre-hypertensive adults, 300mg per day.
  • Supported healthy blood pressure by 8 mmHg (systolic BP) and 5 mmHg (diastolic BP).
  • Participants' average BP readings changed from 133/79 to 125/74 over 8 weeks. The placebo group showed no comparable improvement.
Robinson, M., Lu, B., Edirisinghe, I., & Kappagoda, C.T. Journal of Pharmacy and Nutrition Sciences, 2012
Olive Leaf Extract
Clinical Study: 8-week clinical trial with adults with stage-1 hypertension.
  • Supported healthy blood pressure by 11.5 mmHg (systolic) and 4.8 mmHg (diastolic).
  • Participants saw significant reductions in systolic BP, diastolic BP, and triglyceride levels.
Susalit, E., et al. Phytomedicine, 2011
Coenzyme Q10 (CoQ10)
Clinical Study: Meta-analysis of 12 clinical trials, hypertensive patients.
  • Across 120 participants, CoQ10 supported healthy blood pressure by an average of 16.6 mmHg (systolic) and 8.2 mmHg (diastolic).
Rosenfeldt, F.L., et al. Journal of Human Hypertension, 2007

MegaNatural-BP® Grape Seed Extract

300mg per daily serving • ≥90% Polyphenols

Support Healthy Blood Vessels, Efficient Blood Flow and Physical Performance

MegaNatural-BP® is a patented grape seed extract made from organic, polyphenol-rich California wine-grape seeds.

  • Supports the body’s natural production of Nitric Oxide: Healthy Nitric Oxide production helps blood vessels stay flexible, blood flow more freely, and your heart work less hard.
  • Supports stamina, recovery and physical capability, as healthy circulation helps oxygen and nutrients reach your muscles, organs and brain optimally.

Olive Leaf Extract

800mg per daily serving • >20% Oleuropein • Rich in Antioxidants

Help Protect the Cardiovascular System You Depend on Every Day

The cardiovascular system’s natural defenses weaken as you age, so antioxidant protection becomes increasingly critical for healthy BP and long-term independence.

  • Delivers oleuropein and hydroxytyrosol: Key protective plant compounds that help relax blood vessels and promote healthy blood pressure.
  • Provides antioxidant protection: Helps shield blood vessels from damage caused by harmful free radicals.

Cellular Powerhouse

Coenzyme Q10 (CoQ10)

200mg per daily serving

Maintain Energy, Focus and Recovery With Age

Poorer stamina and slower recovery can make age feel more limiting than it should. CoQ10 supports your cells’ energy production and helps replenish the body’s natural CoQ10 levels that decline with age.

  • Supports heart-healthy energy: CoQ10 is especially important for cardiovascular function because the heart is one of the most energy-demanding organs.
  • Provides targeted support for adults who want to maintain stamina and long-term heart health.

What Our Customers Are Saying

Satisfied Customers, Real Results

Rated 4.82 out of 5 | Excellent

Customer reviews mention:

My readings have been excellent

"Blood pressure was the reason I gave Flow a try. I check mine at home regularly and my readings have been excellent lately. My doctor even complimented how healthy my BP was. Honestly couldn't ask for more. I feel great."

Glenn W.
Age 64

Helping my blood pressure and energy

"I'd been feeling run down for longer than I wanted to admit and I just wasn't keeping up like I used to. Adding Flow made a real difference. I'm getting through long days with more left in the tank and I feel like myself again. My BP has been really good too."

Lisa P.
Age 58

Really glad I started this early

"I'm 38 and my BP was creeping up earlier than expected, but I didn't want to start meds at my age if there was another real option. Flow felt like a smart natural option for my heart health. My numbers are back where I want them and the capsules are easy to take every morning. I plan to keep going."

Chris V.
Age 38

More energy by week 3

"I've bought supplements that did absolutely nothing so I wasn't expecting much. But the afternoon slump I used to get is mostly gone now. I can get through a full workday without reaching for a second coffee and still have energy when I get home. So far, so good."

Marcus L.
Age 46

Got my weekends back

"I've got to say, I'm impressed with Flow. My Saturdays used to be one thing and I was done. Last weekend I played golf, mowed the lawn and still went out to dinner with my wife. I haven't had that kind of stamina in a long time."

Troy S.
Age 61

Simple daily routine I rely on

"By 4 or 5 in the afternoon I used to feel exhausted. Now my energy stays much more even through the day - that's probably the biggest difference I've noticed. I start my days with Heartheris Flow and I wouldn't want to go without it!"

Sheryl N.
Age 52

My stamina is way better than before

"I'm still pretty active at 48, but I could tell I wasn't bouncing back like I used to. I've taken Flow for about 2 months and the difference in my stamina is hard to miss. I don't burn out so fast when I swim or play tennis and I also recover a lot faster afterward. This product really delivers."

Wade R.
Age 48

My wife noticed the difference too

"I originally tried Heartheris Flow for my blood pressure and circulation. A few months in, I clearly have more stamina and I feel stronger physically. My wife has noticed the difference too and that's been a pleasant surprise."

Paul D.
Age 56

Didn't know healthy circulation feels this good

"Wasn't sure what to expect but I feel better when I exercise and my recovery is smoother. Whatever it's doing, it's definitely having a positive effect!"

Colleen A.
Age 54

Husband's heart health isn't a constant worry anymore

"Flow WORKS!! I bought it for my husband because I was always concerned about his blood pressure, even if he wasn't worried about it. Since then his readings have been consistently good and he seems to have more energy too. My dad is now taking Flow as well!"

Amanda S.
Age 44

Feeling better than 10 years ago

"I didn't simply trust Flow at first so I looked up every ingredient and checked the actual studies. It's been a solid addition to my routine. Glad I gave it a chance because I genuinely feel better than I did 10 years ago."

Greg H.
Age 54

My family history made me act before it got complicated

"My mother spent years managing her blood pressure, and I saw how complicated it became over time. When my BP got flagged, I knew I wanted to find a natural path first. Flow had the strongest evidence behind it, and I feel much more confident about my heart health now."

Support Healthy Blood Pressure

Questions Worth Asking

High blood pressure is often called the “silent killer” because it often has no obvious symptoms and goes undetected until a medical crisis.

Over time, high BP places increasing strain on your blood vessels, heart and other organs, raising the risk of heart attack, stroke, kidney failure, vision loss, sexual dysfunction and cognitive decline.

The long-term difference can be significant. In the Framingham Heart Study, adults with healthy BP at age 50 lived 5 years longer than those with high BP, with more years free of cardiovascular disease.

Maintaining healthy BP supports the efficient circulation of oxygen and nutrients throughout your body, and helps protect the cardiovascular foundation for staying active, capable and independent as you age.

Take two capsules daily with a meal. For best results, take one capsule in the morning and one in the evening. Each bottle contains 60 capsules, a full 30-day supply.

Flow™ is formulated with three ingredients that have each been studied specifically for blood pressure support in peer-reviewed clinical trials. In those studies, participants taking the same doses found in Flow™ saw meaningful support for healthy blood pressure levels over 8 to 12 weeks.

While individual results vary, Flow™ is a dietary supplement that works best as part of a heart-healthy lifestyle. To give you confidence in trying it, every first order is covered by our 90-Day Money-Back Guarantee.

Please refer to the full timeline in the "What to Expect" section above. Individual results may vary, but some customers report feeling more energized within the first two weeks. The clinical BP studies on our key ingredients measured outcomes over 8-week and 12-week periods, so we recommend giving Flow™ at least 8 to 12 weeks for the full benefits to develop. This is why we offer a 90-Day Money-Back Guarantee.

Our 90-Day Money-Back Guarantee lets first-time customers try Flow™ completely risk-free. If it's not a fit or doesn't meet your expectations, simply contact us and we'll give you a full refund.

Flow™ is made from natural ingredients and is generally well-tolerated. However, as with any supplement, if you are currently taking blood pressure medication or any other medication, it is always best to consult your healthcare provider before starting any new supplement.

Your healthcare practitioner understands your unique health profile and can help you make an informed decision that aligns with your overall health goals.

Flow™ is formulated using clinically studied ingredients at safe, well-tolerated dosages to support your well-being. It contains no caffeine or stimulants, and is designed for consistent daily use.

Most individuals can take it without any issues when used as directed. In the unlikely event that you experience an adverse reaction, please discontinue use and contact a healthcare professional. 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.

Yes. All three ingredients in Flow™ have established safety profiles and have been used in clinical studies lasting 8 weeks or longer. Flow™ contains no stimulants, caffeine, or habit-forming substances, making it suitable for daily, long-term use as part of a healthy lifestyle.

Absolutely. Flow™ provides proactive, daily support to help maintain healthy blood pressure within the normal range. It works by nourishing the core pillars of your cardiovascular system, like healthy circulation and artery protection, which is important for any adult looking to support long-term heart health.

Flow™ is a triple-action blood pressure support formula that addresses healthy circulation, antioxidant protection, and heart-healthy energy simultaneously, providing comprehensive cardiovascular support.

Other brands typically rely on a single active ingredient, use proprietary blends that hide actual ingredient amounts, or under-dose ingredients. A product listing CoQ10 at 30mg looks identical on a label to one dosed at 200mg. The difference is whether you're getting the amount that was actually used in the peer-reviewed trials cited on our website. Flow™ combines three clinically-backed ingredients at their full researched doses in a single supplement.

Flow™ is also doctor-endorsed, reviewed by healthcare professionals who assessed both the formula and the studies behind it.

The 90-day subscription works out to $1.50 a day, less than many coffees or energy drinks. Buying single-ingredient supplements separately can also mean paying for multiple bottles, routines and reorder schedules. The total cost can quickly exceed the price of one complete formula.

Flow™ combines 3 patented/standardized ingredients in 1 simple trusted formula, with free shipping, the $195 Complete Blood Pressure System, and a 90-day guarantee for you to decide whether it earns a place in your routine.

When you subscribe, your chosen supply of Flow™ is automatically shipped at your selected interval (every 1 or 3 months). You save up to 50% compared to one-time purchases, and all subscriptions include free shipping. You can pause, skip, or cancel your subscription at any time through your account, with no penalties or fees.

We offer a 90-day money-back guarantee on all orders for first-time customers. If you're not satisfied with Flow™ for any reason, simply contact our support team within 90 days of your purchase date for a full refund. No questions asked.

Every subscription to Flow™ includes The Heartheris Complete Blood Pressure System: five expert guides written specifically for adults managing blood pressure naturally, especially after 40.

The guides (retail price: $39 each) cover diet and nutrition, heart-healthy exercise, better sleep and recovery, stress management tools, and a healthy weight and blood pressure framework. Together, they're designed to help you build a practical lifestyle foundation backed by evidence and proven to support healthy blood pressure and long-term cardiovascular health.

The series has a $195 value and is emailed to you with your first order. All active Flow™ subscribers also get complimentary lifetime updates when new content is added or revised in the guides.

Why Healthcare Professionals Recommend Flow™

Dr. Elaine Gavalas

“As a board-certified natural medicine practitioner, I look for formulations that combine clinically studied ingredients with meaningful dosing and a clear rationale. 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.”

Dr. Elaine Gavalas
PhD, Board-Certified Natural Medicine Practitioner
Dr. Ryan Hakim, MD

“Flow™ brings together three ingredients with some of the strongest cardiovascular evidence in the nutraceutical space. MegaNatural-BP® grape seed extract has demonstrated meaningful reductions in both systolic and diastolic blood pressure in randomized trials, while oleuropein — the primary bioactive in olive leaf — supports endothelial function and vascular tone through its antioxidant and vasodilatory properties. CoQ10 rounds out the formula by supporting mitochondrial efficiency in cardiac tissue, where energy demand is highest. For individuals focused on proactive cardiovascular health, this is a formula I feel confident recommending.”

Dr. Ryan Hakim
MD
Alexandra Jacobs, MS, RD, LDN

“Oxidative stress and inflammation are key drivers of cardiovascular decline, and dietary nutrients can make a significant difference. As a registered dietitian, I pay close attention to a supplement’s ingredients and dosing, and Flow delivers. MegaNatural-BP® grape seed extract and olive leaf extract function as antioxidants that protect blood vessels from oxidative damage and inflammation, and support healthy blood flow. CoQ10 is a compound the body produces naturally to generate energy and is concentrated in the heart, but levels decline with age, making supplementation meaningful for long-term cardiovascular support. This is a supplement I trust and regularly recommend because diet alone rarely covers everything your cardiovascular system needs.”
