At Proactive, taking an active role in your health is personal, even for our physicians.

In this video, Dr. Loewenbein shares what brought him to the TPE treatment chair: his genetically elevated lipoprotein(a), or Lp(a), and his commitment to understanding his own health risks.

We’ve shared how plasma exchange works. This conversation offers a more personal perspective on why someone may choose to undergo it as part of an individualized care plan.

For us, proactive healthcare starts with knowing your risks, asking thoughtful questions, and making informed decisions with your medical team. It’s the same care and intention we bring to our patients and to ourselves.

Every treatment requires individual medical evaluation. This video reflects one physician’s personal experience.

GLP-1-based medications have changed what is possible in obesity treatment, but they have also created a more sophisticated question: what is happening to body composition as weight decreases?

Significant weight loss can include reductions in both fat mass and lean mass. Importantly, lean mass is not identical to skeletal muscle, so changes in a body-composition measurement should be interpreted with appropriate context.

Current research also suggests that the effects on lean tissue are not identical across every medication, dose, study, or patient, which is why we would not describe problematic muscle loss as an inevitable consequence of GLP-1 treatment.

What makes sense is protecting the outcomes that matter long term: strength, physical function, adequate nutrition, resistance training, and healthy body composition.

If the goal is healthspan, success should not be measured exclusively by becoming lighter. Preserving the physical capacity you want to carry into later life deserves to be part of the conversation as well.

At Proactive Longevity, the first visit begins with understanding the patient’s health rather than starting with a predetermined treatment package.

The evaluation may include a review of medical history, medications, laboratory results, family history, energy, recovery, and body composition, helping identify which areas deserve closer attention.

Based on those findings, additional evaluations or therapies may be considered according to individual needs, including metabolic testing, lung optimization, advanced immunotherapies, and other longevity-focused modalities.

The objective is to provide a clearer picture of current health, establish meaningful priorities, and develop a personalized strategy for managing health and aging over time.

Protein has become one of the dominant conversations in nutrition, and there is good reason for that. Adequate protein is important, particularly when preserving muscle becomes a priority.

The problem begins when one nutrient becomes a substitute for thinking about the rest of the system.

Muscle also needs a reason to adapt. Resistance exercise provides that stimulus, while nutrition provides the materials and energy needed to support recovery and adaptation.

Then there is everything surrounding those two pieces: overall diet quality, sleep, physical activity, metabolic health, consistency, and whether the plan is sustainable enough to maintain for years.

Healthy aging is rarely built around discovering one perfect nutrient. More often, it comes from making several important fundamentals work together exceptionally well.

Not all Muse Cells are the same. The origin and verification of the cells are important when evaluating regenerative treatments.

At Proactive Longevity, we work with Muse Cells connected to the research of Dr. Mari Dezawa, who originally identified this cell population, with access through Muse Cell Innovations.

Our involvement also extends to the scientific side of this developing field, with representation on the Muse Cell Innovations Scientific Advisory Board.

For patients exploring Muse Cell Therapy, understanding exactly where the cells come from and how they are characterized should be an important part of evaluating any treatment option.

Menopause is often discussed primarily through symptoms such as hot flashes, changes in sleep, mood, or sexual health.

Those concerns matter, but this biological transition takes place within a much larger conversation about women's health through midlife and beyond.

Bone health, body composition, cardiovascular risk, metabolic health, sleep, cognition, and other factors become increasingly important to evaluate during this period.

A recent entry in Scientific Perspective adds another question to the field: could ovarian and reproductive biology provide information about broader physiological resilience and the way different systems age together?

That idea is still being investigated, and we would not describe ovarian decline as the cause of systemic aging. But menopause can be an important opportunity to stop looking at individual symptoms in isolation and assess health more comprehensively.

Researchers are exploring whether stem cell-derived beta cells could restore insulin production in people with Type 1 Diabetes, moving treatment beyond simply replacing insulin.

Early clinical studies have reported encouraging results, including improved blood glucose control, reduced insulin requirements, and insulin independence in some participants following transplantation of stem cell-derived islet cells.

This remains an experimental approach, and important challenges such as immune rejection, immunosuppression, long-term durability, and accessibility are still being studied.

The research represents an important step toward cell-based therapies for Type 1 Diabetes, but larger and longer-term studies are still needed before these treatments can become routine clinical care.

For decades, female biology was often treated as a source of experimental complexity. Hormonal cycles, pregnancy, menopause, and reproductive history made research more difficult to standardize.

A recent article in Scientific Perspective asks a more provocative question: what if some of those differences are not experimental noise, but valuable biological information?

The proposed Reproductive Resilience Hypothesis explores whether evolutionary pressures surrounding reproduction, caregiving, and survival could help explain mechanisms of resilience across the lifespan.

This remains a hypothesis. It does not establish that ovarian aging controls systemic aging, nor does it identify a new treatment for extending longevity.

What makes the idea important is the question it changes. Instead of asking how female biology complicates aging research, scientists may increasingly ask what female biology can teach us about aging itself.

Knee pain does not always mean Joint Replacement is the next step. For selected patients, regenerative approaches such as Stem Cell Therapy are being investigated as potential nonsurgical options.

Stem cells are being studied for their potential role in modulating inflammation and supporting the joint environment, particularly in conditions involving cartilage degeneration. However, their ability to reliably regenerate cartilage remains under investigation.

At Proactive Longevity, regenerative protocols are considered according to the patient’s diagnosis, joint health, medical history, and individual goals rather than as a replacement for surgery in every case.

Stem Cell Therapy for knee conditions remains an evolving area of medicine. Understanding what the current evidence supports, and whether a regenerative approach is appropriate for the individual patient, is an important part of treatment planning.

We tend to organize health around age. Screening recommendations, risk conversations, and even our expectations for physical performance are often influenced by the number on a birth certificate.

But two people who are both 55 can have remarkably different levels of cardiovascular fitness, strength, body composition, metabolic health, and physical capacity.

That is why we are interested in measurements that tell us something about function. VO2 max, strength, glucose regulation, body composition, sleep, and cardiovascular markers can provide information that chronological age alone cannot.

No individual metric defines someone's biological future. The real value comes from looking at several measurements together and understanding how they change over time.

We are less interested in whether someone is simply “young for their age” than in identifying which systems are performing well today and which deserve more attention for the decades ahead.
