Beyond the Hype: Dr. Ronna Parsa on Stem Cell Myths and Proactive Healthspan

In the United States, women represent just eight percent of all practicing orthopedic surgeons. Dr. Ronna Parsa is not only a proud member of this select group. She is also a leading voice in rewriting the playbook on joint care, sports medicine, and human longevity.

As the founder of Parsa Orthopedics and the Mend Institute in Manhattan Beach, California, Dr. Parsa cut her teeth training under the legendary sports medicine pioneer Dr. James Andrews, founder of the Andrews Institute. Her background as a competitive athlete paired with her world-class surgical training sparked a deep passion for a rapidly expanding field: regenerative medicine.

In this episode of Future Proof with Forever Labs, we sit down with Dr. Parsa to discuss why the future of orthopedics relies on healing the body from the inside out, the critical differences between treating with your own cells versus donor cells, and how to safeguard your mobility for decades to come.

The Pro Athlete Reality Check and the Lesson of Recovery

During her fellowship at The Andrews Institute, Dr. Parsa regularly treated elite collegiate and professional athletes, including players navigating life after football through The Trust, an organization that supports NFL players as they live their purpose beyond football. What she observed across these high-performing individuals was a startling trend: intense physical strain meant that 30- and 40-year-old athletes frequently presented with joints that looked like they belonged to a 70-year-old. They were wearing down their biological foundations at an alarming rate.

You don’t have to be a professional football player to experience accelerated joint wear, however. For the everyday ‘weekend warriors’ diving headfirst into fast-growing sports like pickleball, Dr. Parsa emphasizes that orthopedic health requires a highly diversified routine.

It is no longer enough to simply log miles on a treadmill or lift heavy weights. A truly sustainable physical practice must seamlessly blend cardiovascular work, strength training, and dedicated mobility or pliability training to maintain joint elasticity and prevent sudden injury.

Equally vital to this equation is the often-overlooked concept of rest:

"We can work out all day long, but if we don't give our bodies the time to recover, rebuild, and reestablish a baseline normal, healthy tissue, we will eventually start accumulating injuries." —Dr. Ronna Parsa

Mechanical Stability Meets Biologic Healing

Historically, orthopedic medicine functioned much like structural engineering. Surgeons focused almost entirely on providing mechanical stability: fixing fractures, reconstructing ligaments, and letting the body figure out the rest on its own. If a joint failed to heal, patients were left with few options outside of localized cortisone shots or highly invasive revision surgeries.

Dr. Parsa’s perspective transformed during an international research trip to Malaysia, where she collaborated with Dr. Khay-Yong Saw at the Kuala Lumpur Sports Medicine Centre on pioneering cartilage regeneration protocols. Witnessing cartilage actively grow and heal via sequential MRI tracking opened her eyes to the immense latent healing power locked within human biology.

Today, the most sophisticated sports medicine happens at the intersection of structural and cellular care. By pairing mechanical alignment with advanced biologics like Platelet-Rich Plasma (PRP) or point-of-care autologous bone marrow stem cells, physicians can deliver concentrated cellular signals directly to damaged tissue, effectively restarting a stalled healing cascade.

Why You Are Your Own Best Donor

With the explosion of longevity content across social media and podcasts, a massive part of Dr. Parsa’s daily work involves educating patients and debunking common myths. One area she frequently discusses is the growing trend of medical tourism for regenerative therapies, where patients travel abroad seeking treatments such as allogeneic stem cell therapies—cells sourced from donor tissue like umbilical cords or placentas.

While medical tourism itself is not inherently unsafe, Dr. Parsa emphasizes that pursuing treatments without thoroughly researching the clinic, regulatory standards, safety protocols, and scientific evidence can carry significant risks. In many cases, patients may not fully understand what they are receiving, how the cells were processed, or whether the treatment has been properly studied or regulated.

With the rise of medical tourism for regenerative therapies, allogenic stem cell therapies (using stem cells harvested from donors) have become a hot topic. While some patients are unaware of where the stem cells used in their therapies come from, others choose allogeneic over autologous stem cell therapies under the impression that younger donor cells (which can be sourced from placentas and amniotic fluid) would yield superior results.

However, stem cells can migrate to a patient's bone marrow to replicate. Injecting someone else’s cells into your body means you are introducing someone else's DNA into your body. Without long-term peer-reviewed data or transparency regarding donor family histories, patients run the unpredictable risk of immunogenicity or tumorigenesis.

“If you are receiving viable cells from a different donor, you are also receiving someone else’s DNA. I don’t think many people fully understand that concept, and it can be shocking for them to realize: ‘Wait, I’m receiving someone else’s DNA?’ There’s a reason why, when treating leukemia in the United States — or anywhere in the world — physicians carefully check for HLA matches before proceeding.”

Changing the gears on legislations

The landscape of regenerative medicine in the United States is shifting rapidly. Driven by progressive “Right to Try” legislative frameworks in states like Florida and Texas, alongside the completion of advanced, cGMP-compliant cell culture expansion facilities, American medicine is beginning to unlock the true potential of cellular therapies.

One example is Forever Labs’ new facility in Jupiter, which reflects the growing infrastructure supporting the future of regenerative medicine.

Because cellular healing is fundamentally dose-dependent, the ability to safely expand a patient's stored cells into hundreds of millions of highly active, youthful therapeutic units changes everything. Landmark genetic mouse models have already demonstrated that reintroducing youthful stem cells can successfully prevent age-related diseases like osteoporosis while extending overall lifespan by 20%.

Future-Proofing Longevity and Women's Health

In honor of National Women's Health Month, Dr. Parsa emphasizes that women can take immediate, proactive steps to support their orthopedic healthspan and preserve long-term mobility. Key recommendations include:

• Monitoring and optimizing Vitamin D3 levels to support bone density and soft tissue repair
• Incorporating progressive strength training to help preserve muscle mass, strengthen joints, and stimulate bone density through consistent skeletal loading
• Prioritizing mobility and musculoskeletal health early, rather than waiting for pain or injury to appear with age

Dr. Parsa actively lives the longevity protocols she recommends. Years ago, at the beginning of her medical career, she chose to bank her own mesenchymal stem cells with Forever Labs.

"I banked my cells in the beginning of my practice. It took 20 or 30 minutes, and now I have this access to my younger cells for the rest of my life. I try to get all my family and friends to do it too"
