Once membership opens, you will be notified and joining takes just a few minutes. We’ll introduce you to Corwin, orient you to the app and our offerings, help you get started with your comprehensive health assessment, order your lab panel, begin guiding you through your personalized health journey and welcome you to the 3 Billion Beats family.

The human heart beats approximately 3 billion times over the course of a lifetime. Each beat makes possible the experience, relationships, milestones, adventures, and moments that matter most.

The good news is that approximately 90% of heart attacks are preventable through proactive care, deeper health insights, and intentional choices that can have a profound impact on your health, longevity, and quality of life.

At 3 Billion beats, we’re dedicated to helping you protect your heart so you don’t miss a single beat.

Ben and Betsy, a medical and dental duo husband-and-wife team who have known each other since they were 15 years old, built 3 Billion Beats around one simple idea: make proactive, personalized root cause care as accessible and affordable as possible and provide the level of care they give to their own family - thoughtful, thorough, and on call.

To learn more about who we are and our mission, read here:

We encourage people to begin comprehensive cardiovascular screening as early as their 30s and 40s - before symptoms appear and before disease progresses.

Early insight creates more opportunities to:

• Detect hidden disease before it becomes a problem
• Identify and address the root drivers of cardiovascular risk
• Make targeted lifestyle and health changes
• Track progress and adjust strategies over time

In general, we focus on three key populations:

1. High-risk individuals overlooked by traditional screening
We identify people who may be at significant cardiovascular risk but are missed by standard primary care and cardiology screening approaches. Many individuals are told they are “fine” because their basic cholesterol panel looks normal, yet they may have hidden risk factors that are not captured by conventional testing. By uncovering early signs of disease and addressing root drivers of cardiovascular risk, we help prevent first-time heart attacks before they happen.

2. Individuals with high cholesterol or known coronary artery disease but no prior heart attack
We provide structured, personalized strategies to slow and stabilize disease progression by addressing the underlying factors driving cardiovascular disease. Our goal is to help people reduce their risk and prevent a first cardiac event through comprehensive monitoring, lifestyle optimization, and targeted interventions.

3. Heart attack survivors seeking to prevent future events
We help individuals with a history of heart attack reduce their risk of recurrent cardiovascular events through ongoing risk assessment, advanced monitoring, and individualized prevention plans designed to address the factors contributing to disease progression.

Anyone 18 years or older can join.

If you are currently pregnant, we recommend waiting until after your pregnancy to enroll. Pregnancy causes significant hormonal and metabolic changes that can affect the interpretation of many lab results. In addition, pregnancy will prevent you from undergoing recommended imaging studies and may limit certain lifestyle or treatment recommendations.

We were founded in Watertown, Massachusetts, a suburb just outside of Boston known for its excellent Armenian bakeries and baklava.

Nationwide in all 50 states.

Many people who want a more complete assessment of their cardiovascular health are unable to access advanced laboratory and imaging tests, including:

• Advanced lipid, metabolic, inflammatory and full body systems testing
• Coronary CT angiography (CCTA)

There are 2 primary reasons for this:

• Many physicians are reluctant to order these tests because they are not routinely recognized or recommended under current traditional clinical practice guidelines.
• Even when a clinician is willing to order them, insurance coverage is often denied because they do not meet the health insurance plan's medical necessity criteria.

Through our direct-to-consumer platform, you can access advanced testing based on your individual risk profile and clinical needs, not solely on the limitations and discretion of the traditional healthcare system or insurance coverage decisions.

The result is a more personalized understanding of cardiovascular risk, helping identify disease that might otherwise remain undetected. This provides actionable information for you and helps support informed discussions with your healthcare team.

Another key advantage of the 3 Billion Beats model is complete price transparency. We offer all laboratory testing and imaging at cost, meaning with NO markups or hidden fees. We make no money on labs and imaging so we can keep prices down as much as possible for you. We believe patients deserve affordable access to the information that can improve - and even save - their lives. One of the many benefits of working with us is that we take care of you like we take care of our own families.

No. 3 Billion Beats is designed to complement - not replace - your existing healthcare team. Our goal is to make you a more informed, empowered, and proactive participant in your health. Think of us as the layer of education, data, and family-style care around your existing doctors - never a substitute for traditional care.

Through advanced lab testing, cardiac imaging, and personalized insights, 3 Billion Beats helps you develop a deeper understanding of your cardiovascular health, identify potential risks earlier, and have more meaningful conversations with your healthcare providers. You (and Corwin) can bring these insights to your PCP, cardiologist, or other members of your care team to support more informed discussions and shared decision-making.

Doctors play an essential role in diagnosing, treating and managing your medical care. The functional medicine perspective is intended to provide an additional, complementary lens to help improve your care and increase your understanding of your own health. It does not replace or negate traditional medical care.

From a functional medicine perspective, cardiovascular health is influenced by many interconnected factors - including inflammation, oxidative stress, metabolic health, nutrition, lifestyle, and other contributors. Rather than focusing only on managing individual biomarkers or treating disease after it develops, functional medicine aims to understand the underlying drivers of risk and support a more comprehensive, prevention-focused approach.

3 Billion Beats is a healthcare technology company and Management Services Organization (MSO) that provides the technology platform, AI-powered insights, and administrative support that make personalized preventive healthcare more accessible.

Clinical services - including lab ordering, the annual Physician Chart Review (the CCTA consult), CCTA imaging, and medical oversight - are provided by 3 Billion Beats Medical, PA, an independent physician-owned practice that 3 Billion Beats contracts with. The PA’s supervising physician is licensed in all 50 U.S. states and is responsible for clinical oversight and medical decision-making. Your membership itemizes the CCTA consult separately.

This MSO-PA structure is a widely used healthcare model that allows licensed physicians to maintain control over clinical care while enabling innovative healthcare technology companies like 3 Billion Beats to deliver a seamless, modern patient experience.

Functional medicine is a personalized approach to healthcare that focuses on identifying and addressing the root causes of disease rather than simply managing symptoms. It uses a systems biology approach, recognizing that the body’s systems are deeply interconnected and that imbalances in one area can contribute to or cause symptoms in another.

Unlike the traditional symptom-focused model of care, functional medicine practitioners look upstream to understand the complex factors that influence health, including genetics, physiology, environmental exposures, nutrition, lifestyle, stress, emotional health, and medical history.

A simple example: conditions such as eczema, psoriasis, and restless leg syndrome are frequently caused by underlying factors such as microbiome imbalances, nutrient deficiencies, inflammation, and chronic inflammation. By identifying and addressing these root drivers, symptoms can be resolved rather than being managed indefinitely by medications. Functional medicine aims to restore balance and support the body’s natural ability to heal.

Functional medicine can be used both to help address chronic health conditions and proactively optimize health, prevent disease, and promote long-term wellness.

Functional cardiology applies the principles of functional medicine specifically to cardiovascular health. Rather than focusing only on managing cholesterol numbers or relying on oversimplified, one-size-fits-all risk calculators that fail to consider the full context of your health, functional cardiology takes a proactive, root-cause approach to understanding and optimizing the many interconnected factors that influence heart health.

Functional cardiology looks beyond traditional markers such as cholesterol, blood pressure, and blood sugar to evaluate the broader drivers of cardiovascular risk, including inflammation, metabolic health, insulin resistance, nutrition, lifestyle factors, genetics, environmental exposures, sleep, stress, hormones, gut health, and other factors that influence vascular health.

By combining advanced testing, imaging when appropriate, and personalized, evidence-based interventions, functional cardiology aims to identify cardiovascular risk earlier, prevent disease before it develops, or slow disease progression when possible. It shifts the focus from simply managing cholesterol levels and cardiovascular disease to understanding why risk develops and creating a personalized plan to improve long-term outcomes.

For a more complete understanding of how this approach differs in both principle and practice, please read our "How We're Different" section.

Yes - for certain clinical services.

Our Coronary CT Angiography (CCTA) cardiac imaging service supports insurance coverage. When you elect to use insurance, we verify your eligibility and benefits in real time, coordinate prior authorization when required, and facilitate claims through our affiliated physician practice.

For our lab testing packages, we operate on a transparent self-pay model. Traditional lab pricing can often be confusing and unpredictable because many lab companies set high list prices that are later negotiated down by insurance companies. If your insurance company denies coverage, you may be responsible for a significant and unpredictable bill. Additionally, even when insurance plans indicate that they cover laboratory testing, copays, deductibles, and plan-specific requirements can still result in substantial out-of-pocket costs.

A key advantage of the 3 Billion Beats model is complete price transparency. We offer all laboratory testing and imaging at cost, with NO markups or hidden fees. We intentionally do not make money on labs or imaging, allowing so we can keep prices as low as possible for you. We believe patients deserve affordable access to the information that can improve - and even save - their lives. One of the many benefits of working with us is that we take care of you like we take care of our own families.

Yes. Our membership (which includes lab testing) and our additional Coronary CT Angiography (CCTA) imaging services qualify as HSA/FSA-eligible medical expenses. You can use your HSA or FSA debit card directly at checkout, with no reimbursement paperwork required. Alternatively, we can provide an itemized receipt that you can submit to your HSA/FSA provider for reimbursement.

We also partner with Plaid, a secure financial technology platform, to help you check the available balance of your HSA or FSA funds before purchase.

When you choose to undergo a CCTA through our platform, we simplify the insurance process and handle all the details for you:

Insurance Verification: We verify your insurance coverage in real time using your insurance card information to determine eligibility and benefits.

Prior Authorization: If required by your insurance plan, we coordinate the prior authorization process through 3 Billion Beats Medical, PA.

Imaging Facility Coordination: We schedule your scan at an in-network imaging facility conveniently located near you.

Cost Transparency: Before you move forward, we provide an estimate of your expected out-of-pocket costs, including any applicable copay, coinsurance, or deductible amounts.

If you prefer not to use insurance - or if self-pay is more affordable based on your specific insurance benefits and out-of-pocket costs - cash-pay pricing is always available with transparent, upfront pricing.

We accept all major credit and debit cards, HSA/FSA cards, and PayPal — plus Klarna, Affirm, and Afterpay if you'd like to spread your annual membership into smaller payments over time. For CCTA imaging, we also support insurance billing. All transactions are processed securely through PCI-compliant payment processors.

After signing up, log in to 3 Billion beats to schedule your blood draw appointment. You will receive a requisition and visit a location near you for a blood draw. Once the results are ready, they are securely uploaded to your 3 Billion Beats dashboard, where our AI analyzes the data and generates your personalized Health Story with actionable insights.

For all states except New York and New Jersey, we partner with Quest Diagnostics, which has more than 2,000 patient service locations nationwide.

Due to state-specific laboratory regulations, patients in New York and New Jersey are served through BioReference Laboratories.

Yes. We recommend fasting for 10–12 hours, typically overnight, before your blood draw. During your fast, you may drink water, black coffee, or unsweetened tea, but avoid adding milk, cream, sugar, or other sweeteners. It’s a good idea to stay well-hydrated because it makes it easier for the phlebotomist to collect your blood sample.

Approximately 15 minutes.

Most likely, yes. Corwin, along with our human-in-the-loop medical team, will help you determine which biomarkers are worth tracking over time and recommend how often they should be repeated based on your individual health goals and results.

As a member, you can also order any available biomarker on demand at our cost - with no markups - whenever you want to monitor your progress.

Click here to see the full list of biomarkers we test and learn why each one matters.

Yes. We recommend having your blood drawn in the morning. Morning testing provides the most accurate assessment of hormones such as testosterone and cortisol.

No. Continue taking your medications as prescribed unless your healthcare provider specifically instructs you otherwise. Never stop taking a prescribed medication without first consulting your healthcare provider.

Biotin (vitamin B7) can interfere with certain laboratory tests, including some thyroid and hormone markers. If you take a biotin supplement, we’d recommend stopping it 72 hours before your blood draw.

Yes. If you're having heavy metal testing, avoid eating seafood for 48 hours before your blood draw, as it can temporarily increase mercury levels and affect your results.

Your results are delivered as soon as they are available - some within a few days but the complete panel may take up to several weeks.

Once all of your results are available, our AI health guide, Corwin, and our clinical team review your data and provide a written summary to help you understand what your results mean in the bigger picture of your health.

If any of your results indicate a potentially urgent or critical finding, a healthcare provider will contact you directly as soon as possible to discuss the results and next steps.

While lab testing is highly accurate, errors can occasionally occur. Factors such as dehydration, not following fasting instructions, certain medications or supplements, and temporary changes in your health can sometimes affect results.

If you or your healthcare provider suspect that a result may not accurately reflect your health, we recommend repeating the test to confirm the finding.

Once your results are available, you can log in and download a PDF report to share with your healthcare provider. You can also bring Corwin with you to your appointment and use him as a resource to help explain your results and provide additional context for your healthcare team.

Yes. You can upload your health records, including lab results, imaging reports, procedure reports, and medical consultation notes, to the 3 Billion Beats portal. This allows you to keep all of your health information organized in one place over time and gives Corwin and our clinical team the most complete context to better understand your health and provide personalized guidance.

Testing in New York and New Jersey may have additional costs due to state-specific regulations and requirements. If you are located in either state, we’ll clearly explain any differences and walk you through the details during the scheduling process.

A coronary CT angiogram (CCTA) is a noninvasive, advanced imaging test that uses CT technology and contrast dye to create detailed images of the coronary arteries, the blood vessels that supply blood to your heart.

The most commonly used screening test, the coronary artery calcium (CAC) score, measures only the amount of calcified plaque in the coronary arteries and provides a single calcium score. While a CAC score is valuable for risk stratification and assessing cardiovascular risk, it does not show the full picture of coronary artery disease.

A major limitation of CAC scoring is that it cannot detect the types of plaque that may be most likely to rupture and trigger a heart attack. A calcium score cannot identify:

• Soft (non-calcified) plaque
• Lipid-rich plaque
• Vulnerable plaque prone to rupture
• Early-stage atherosclerosis before calcification occurs

This is particularly important because heart attacks are often caused by the rupture of vulnerable, non-calcified plaque rather than heavily calcified plaque.

A calcium score of zero does not mean a person is free of coronary artery disease. Studies have shown that approximately 20–25% of acute coronary events occur in individuals with a CAC score of zero, particularly in younger adults and those with metabolically active, non-calcified plaque.

As a result, some patients may be falsely reassured that their arteries are “clean” when potentially dangerous disease may already be developing beneath the surface.

A CCTA provides a more comprehensive assessment by directly imaging the coronary arteries and identifying both calcified and non-calcified plaque, including early-stage plaque that may not yet be visible on a calcium scan. It can measure overall plaque burden and evaluate whether plaque is causing narrowing or blockages in the coronary arteries.

A CCTA can help evaluate:

• Total coronary plaque burden (the overall amount of plaque in your arteries)
• Calcified and non-calcified plaque
• Lipid-rich, high-risk plaque features associated with increased cardiovascular risk
• Plaque composition and morphology
• The degree of narrowing or blockage in your coronary arteries
• Early atherosclerosis before significant calcification develops

By identifying and quantifying coronary plaque earlier, a CCTA can help you and your healthcare team make more informed decisions about prevention, treatment, and personalized strategies to reduce your risk of future heart disease.

During a CCTA, a small IV is placed in your arm so contrast dye can be administered. You will lie on a CT scanner table while detailed images of your heart are captured, typically during a brief breath hold. The scan itself usually takes only a few minutes, although the entire appointment may take longer due to preparation, heart rate optimization, and monitoring.

To improve image quality, some people may receive medication to temporarily lower their heart rate before the scan. The test involves a low dose of radiation and the use of iodinated contrast, so your care team will review your medical history, kidney function, allergies, and other factors to determine if CCTA is appropriate for you.

A CCTA may be a recommended option based on your individual health profile, including your lab results, symptoms, personal risk factors, family history, and overall goals for understanding your heart health.

Our clinical team will help you determine whether a CCTA is appropriate for you and whether the additional information it provides would be valuable in guiding your prevention and treatment strategy.

Preparation instructions may vary slightly by imaging center, but in general, you should:

• Avoid caffeine for at least 12 hours before your scan, as caffeine can increase your heart rate and affect image quality.
• Stay well hydrated before and after the test unless your healthcare provider has instructed you otherwise.
• Follow any fasting instructions provided by your imaging center. Many centers recommend avoiding food for a few hours before the scan.
• Continue your medications unless instructed otherwise. Do not stop any prescribed medications without first speaking with your healthcare provider.
• Inform your care team if you have any allergies, kidney disease, or a history of reactions to iodinated contrast dye.

Before the scan, your heart rate may be checked, and some people may receive medication to temporarily lower their heart rate to help obtain the clearest images possible. Your imaging team will provide specific instructions based on your health history and the requirements of the facility performing your CCTA.

The CCTA Concierge is included with your 3 Billion Beats membership — one of its most valuable benefits.

Obtaining a CCTA typically requires finding a physician willing to order the test, navigating medical protocols, coordinating with imaging facilities, and understanding insurance requirements. This process can be time-consuming and frustrating, and many patients face challenging barriers. Our goal is to save you time, reduce the administrative burden, and make the entire process simple and seamless.

Through 3 Billion Beats, our team handles the coordination from start to finish, including:

• Annual Physician Chart Review and CCTA order provided by 3 Billion Beats Medical, PA — the independent physician practice we contract with. A licensed physician personally reviews your chart (labs, history, risk factors) — it's a records-based review, so there's no appointment to book and no waiting room
• Insurance coordination and advocacy, including eligibility verification and prior authorization support when needed
• “Find Your CTA” service to compare cash-pay pricing options at imaging centers near you
• AI-assisted appointment coordination to help identify and schedule with appropriate facilities
• Real-time status updates from Corwin via text so you can track your progress throughout the process
• Follow-up coordination — if your results need attention, we coordinate with our Physician Network and your PCP or cardiologist

The service covers the coordination, physician review, and support required to access your CCTA. The scan itself is the one cost outside membership.

You pay the imaging facility directly for the CCTA. Typical cash-pay pricing ranges from $399–$759, depending on the location and facility. It’s also possible that your insurance may also cover the scan, and we will verify coverage in real time and help advocate for prior authorization when appropriate.

You can choose the option that works best for you financially and logistically: use insurance, pay with an HSA/FSA card, or pay cash. HSA/FSA cards are accepted for the facility imaging fee.

For comparison, most direct-to-consumer CCTA ordering services charge $500-$1200 just for the physician review to get the imaging ordered, and then an additional cash-pay cost for the imaging itself ranging from $500-$1100.

The value of our concierge CCTA ordering and coordination service alone is massive and is included in your membership.

Your annual Physician Chart Review is exactly what it sounds like — a records-based review of your chart, not a telehealth appointment. There's no video visit to schedule and no waiting room.

A licensed physician at 3 Billion Beats Medical, PA — the independent physician practice we contract with — personally reviews your labs, health history, and risk factors, and makes a real clinical decision: if a CCTA is appropriate, they write the order and the concierge takes it from there; if it isn't, you get a clear explanation of why and what we'll watch in your labs instead.

Most doctors won't order a CCTA at all — this review is how 90 Nation members get one, without booking a single appointment. And Corwin plus your care team are available every day for the questions in between.

When combined with Cleerly’s FDA-cleared AI-powered plaque analysis, your CCTA images can be analyzed at a much deeper level to provide a comprehensive assessment of your coronary artery disease risk.

Cleerly uses artificial intelligence to analyze thousands of data points from your CCTA images and creates a detailed, personalized map of your coronary arteries. This analysis helps identify:

• Where plaque is located throughout your coronary arteries
• How much plaque is present (total plaque burden and disease volume)
• What type of plaque is present, including calcified, non-calcified, and mixed plaque
• Whether plaque has high-risk characteristics associated with increased risk of future cardiovascular events
• Which arteries and segments are affected and the severity of disease in each area

Unlike traditional testing that may focus primarily on whether there is a significant blockage, Cleerly provides a more complete view of coronary health by helping detect and quantify early atherosclerosis before symptoms develop or before severe blockages occur.

Your Cleerly report transforms your CCTA into a detailed “roadmap” of your coronary arteries, helping you and your healthcare team better understand your current cardiovascular risk and make more personalized decisions about prevention and treatment.

No. Cleerly AI analysis is an optional enhancement that can provide additional detail from your Coronary CT Angiography (CCTA), but it may not be necessary or appropriate for every individual based on your CCTA results.

A standard CCTA already provides a lot of valuable information about the structure of your coronary arteries, including the presence, location, and severity of any narrowing or blockages. Cleerly’s FDA-cleared AI-powered analysis adds an additional layer of assessment by quantifying total plaque burden, identifying plaque composition, and evaluating features associated with higher cardiovascular risk.

Whether Cleerly analysis is recommended depends on your individual health profile, goals, risk factors, and clinical circumstances. It may be especially valuable for individuals who want a more comprehensive understanding of their coronary health, have elevated cardiovascular risk factors, have evidence of plaque or early disease, or want more detailed information to guide prevention strategies.

At 3 Billion Beats, our goal is to provide access to advanced tools that help you better understand your health - not to recommend unnecessary testing. We believe the right level of analysis should be personalized based on your unique risk profile and health goals.

Corwin is your AI-powered health guide and coach built into the 3 Billion Beats platform. The name combines “cor,” the Latin word for heart commonly used in medicine, with “win,” because our mission is for you and your heart to achieve big wins while working with us.
