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.

Armed with the latest advances from the fields of longevity and lifestyle medicine, our doctors 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.

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.

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.

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

  • Your relative long term risk for Alzheimer's and dementia can be evaluated.
  • Improving sleep hygeine, lifelong learning, and temperature therapry are explored as preventive options for neurodegenerative disease.
  • Advanced early cancer screening can be appropriate for certain patients.

Actionable Recommendations

  • Medication Icon

    Early Medical Treatment and Supplementation

    High risk patients may benefit from early statin usage or metformin to help them entirely avoid heart disease or diabetes. Novel therapies such as rapamycin, PCSK9 inhibitors, and more can be explored to slow down disease and the process of aging. We may recommend long term medications to discuss with your PCP  based on the results of your testing.
  • Heart Repair Icon

    Specific Diet and Exercise Recommendations

    When we intervene before disease starts, lifestyle changes can be used as a very effective treatment. Nutritional recommendations such as diet changes or intermittent fasting, and fitness routines such as a focus on strength training or Zone 2 cardiovascular training are all considerations to help reduce your specific risk factors.
  • EKG Icon

    Aggressive Screening, Alternative Therapies, and More

    Your results may indicate that earlier screening tests are appropriate, or that cold water immersion therapy might reduce your risks of long-term disease. Some patients might need to prioritize sleep above all else. Armed with a personal toolkit of information, we can make specific recommendations that will actually make a difference in your life.

Dr. Rebecca Bub Primary Care near Denver CO

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.

Not Included
Pure Longevity is a consultation service and does not provide ongoing care. Our program is meant to empower you with the knowledge and recommendations needed to make specific changes that will lead to a long and healthy life. It is not a substitute for a primary care doctor or specialist as we do not provide ongoing management, follow-up, or prescribe medication for illnesses that may be diagnosed through this program.
We strongly believe that ongoing primary care is vital to long term health. If you are looking for a PCP, Dr. Cameron is accepting new primary care patients through our direct primary care membership, or you can use the information we provide in this program to take a more proactive role with your current PCP or specialists.
