Discover Healthy Aging with Pure Longevity

Traditional healthcare is failing us when it comes to maintaining health and vitality as we age. By treating disease after it has already started, we are increasing lifespan while decreasing quality of life. Pure Longevity is here to change that.

Our goal is to help you avoid disease and injury altogether, so that you can live a long, active, and healthy life. Armed with the latest advances from the fields of longevity and lifestyle medicine, we use evidence-based testing to identify your personal long-term risk factors and recommend interventions that you can take now to optimize your current and future health.

Dr. Rebecca Bub - Family Medicine Doctor in Littleton

Improve your healthspan, not just your lifespan, with pro-active, modern biochemical and genetic testing aimed at identifying disease years (or decades) before it starts.

Find ways to optimize your current health by looking beyond a standard physical exam with metabolic, fitness, and body composition testing.

Make changes now to avoid disease with specific lifestyle, dietary, fitness, and medical recommendations based on your results.

How it Compares

Conventional Medicine vs Pure Longevity

Proactive healthcare has the power to transform the way we think about aging.

Conventional Healthcare

Intervention limited to patients with specific signs that indicate a 10% or greater risk of a heart attack or stroke within the next 10 years.
Most early testing is dismissed as unnecessary.
Fitness is not prioritized for long term health.
Goal is to stabilize cardiovascular disease once it is found.

Pure Longevity

Intervention appropriate for any patient with a heightented lifetime risk of heart attack or stroke.
Early testing has a massive impact on lowering your long term risk.
Fitness is the primary way to achieve cardiovascular health and longevity.
Goal is to completely avoid cardiovascular disease if possible, or at least significantly delay it's onset.

In Depth Information

Advanced Lipid and Apolipoprotein Testing delves deeper than your good and bad cholesterol, proving a comprehensive look at your current and long term genetic risk of developing heart disease.
Advanced CT imaging looks for pre-clinical plaques that may indicate you have hidden signs of early heart disease.
VO₂ Max Testing gauges your current cardiovascular abilities and how your body utilizes nutrients, providing a path to maintaining and improving heart health and physical and metabolic fitness into your advanced age.
Early Lifestyle Interventions and Treatment are possible based on your test results, from earlier usage of statin medication, to diet and exercise plans, and even novel therapies such as a sauna routine.

Conventional Healthcare

Screening limited to obese patients over 40 years old.
A1C considered sufficient screening.
No intervention recommended until diabetes is diagnosed.
Goal is to prolong life and decrease complications of diabetes.

Pure Longevity

Every patient is screened.
Insulin, glucose, and inflammatory markers are checked.
Intervention recommended at the pre-diabetic level or earlier.
Goal is to completely prevent diabetes, heart disease, and cancer.

In Depth Information

Full Biochemical Testing evaluates organ function, checks for evidence-based inflammatory markers, and looks for early evidence of diabetes and other metabolic or inflammatory disorders.
Continuous Glucose Monitoring allows you to see the immediate effects of your diet and lifestyle choices on your blood sugar, empowering you to make immediate changes, and helping us gauge your current and future risk for diabetes and other metabolic diseases.
Comprehensive Insulin Panel determines how effectively your cells are responding to insulin, which can affect your risk of numerous disorders including many cancers.
Recommendations can include early use of metformin and other medications, lifestyle modifications such as diet change and stress management, and Zone 2 cardiovascular training to improve cellular mitochondrial density and support a healthier metabolism.

Conventional Healthcare

Alzheimer's and dementia preventive screening is not common.
Pre-emptive intervention for neurodegenerative disease is not done.
Cancer screening, while common, is often done too late or not aggressive enough.

Pure Longevity

We evaluate your current cognitive function utilizing FDA approved screening tests, and blood testing uncovers your long term risk factors for Alzheimer's and dementia.
Improving sleep hygeine, lifelong learning, and temperature therapy are explored as preventive options for neurodegenerative disease.
Advanced early cancer screening can be appropriate for certain patients.

In Depth Information

Galleri Testing uses advanced DNA detection combined with advances in AI to detect DNA linked to cancer before you could otherwise detect it clinically (optional add-on test).
Genetic Evaluation looks at common genetic biomarkers such as APOE to determine your relative risk of developing neurodegenerative disease as you age.
Other Aggressive Early Screening Recommendations are discussed to help detect cancer earlier than standard medical recommendations. For many patients, earlier colonoscopies and/or mammograms and even MRIs may be recommended.
Lifestyle Recommendations including sleep, continuous learning, and temperature therapy are explored to reduce your risk of certain debilitating diseases.

Rebecca Bub, DO

Owner of Pure Family Medicine
Board Certified Family Medicine Physician
Special Interest in Longevity and Lifestyle Medicine

Dr. Rebecca Bub has always felt that traditional healthcare waits too long to intevene and is stuck managing disease rather than truly preventing it. When she opened Pure Family Medicine, she was free to practice her way and immediately saw amazing results for her patients. From preventing diabetic patients from needing insulin through close monitoring and lifestyle changes, to early intervention for subclinical cardiovascular disease, taking the time to connect with patients and do things differently made a huge difference.

Dr. Bub's career-long interest in improving long term health and vitality through preventive care and lifestyle changes led her to create Pure Longevity. Her approach mirrors advice popularized by recognized health and longevity authorities such as Dr. Peter Attia and his book Outlive, Dr. Andrew Huberman and his popular Huberman Lab podcast, and others.

An interactive, FDA approved assessment to detect changes in cognition before it may otherwise be apparent, allowing for earlier intervention and planning. Patients receive a full cognitive performance report.

Continuous Glucose Monitor

A continuous glucose monitor (CGM) is a small wireless device that you wear on the back of your arm, it has a small filament that is inserted under your skin, and is relatively painless to apply and wear. With a corresponding app on your smart phone you can monitor your glucose levels throughout the day and learn what lifestyle and dietary behaviors affect your blood sugar levels. This data can provide an early warning for insulin resistance and diabetes and can be used to make immediate and effective changes in your diet and lifestyle.

Common Questions

Can I use my health insurance?

Insurance companies don't yet recognize the benefits of early prevention and longevity style medicine, so unfortunately Pure Longevity is not covered by health insurance. Your insurance may still be used for primary care related services if you are with us for ongoing care, including most standard lab testing, diagnostic imaging, vaccines, medications, etc. Keep in mind that when using your insurance, they set the rules on whether a test or treatment is covered, and how much it costs.

Which program should I select?

We strongly believe that longevity medicine, and primary care in general, is best done through an ongoing relationship with your physician. Our Pure Longevity Care program was designed to provide you with the best and most customizable long term healthcare experience.

However, we recognize that not everyone is looking for ongoing care, and some patients prefer a one time workup and then a do-it-yourself approach to long term health. The Pure Longevity Assessment was designed for these patients, where long term care, follow-up, or medications are not desired.

How does my long term and ongoing care work?

Dr. Bub is a board-certified family medicine physician, and will provide your ongoing primary care, with a longevity-minded focus. This includes routine issues such as infectious diseases (strep, flu, covid), minor injuries, preventive care, and more.

As a direct primary care practice, we provide the majority of these services within your monthly fee for no additional charge, at an elevated level of service compared to traditional primary care. Go to our Primary Care Services page to learn more.

What is not included with the Pure Longevity Care program?

Since we are not a health insurance plan, any healthcare you receive outside of our office is not included with membership.

Laboratory testing (apart from the included testing listed above) that is sent to an outside lab, medication, vaccines, and aesthetic services are not included.

When there is a cost for a test or service in our office, we will always let you know the cost up front. We pass along our wholesale prices to you so that your costs are low and predictable.

What if I need additional testing during the program?

Every patient is different. The Pure Longevity Care program allows for a highly customized testing and follow-up plan, so additional testing is never a problem. Since the Pure Longevity Assessment is a pre-set program with up front pricing, we are more limited in customizing your testing plan.

How soon can I book my consultation and exam?

Once you have signed up you can schedule your visit using our online scheduler. Dr. Bub sees patients for longevity consults on Tuesdays and Thursdays, with her first available appointment generally about 2 weeks out.
