In this training, Dr. Irene Pinilla, an aesthetic physician, hair surgeon, and aesthetic medicine educator, shares a practical perspective on functional longevity and how to approach aging from a preventive, metabolic, and integrative viewpoint. The session begins with a fundamental idea: living more years does not always mean living better. The true goal is to preserve autonomy, physical capacity, cognitive function, and the body's resilience for as long as possible. Throughout the training, Dr. Pinilla explains why aging begins long before disease appears, the role of physiological reserve, and how factors such as muscle mass, metabolism, sleep, and inflammation dictate our capacity for adaptation. Within this context, she also explores the role of NAD as a molecule involved in cellular energy production and homeostasis, always understood as a complementary tool within a global health strategy. This approach aligns with the philosophy of be levels, which views supplementation as support built upon solid pillars of nutrition, exercise, rest, and metabolic health. Key takeaways Functional longevity: adding life to years One of the main messages of the training was the distinction between living longer (lifespan) and living those years with autonomy and quality of life (healthspan). The goal is not only to delay the onset of disease, but to maintain the following for longer: / strength/ cognitive capacity/ independence/ physiological resilience Loss of function begins before disease Dr. Pinilla explained that physiological decline begins long before a clinical diagnosis appears. Some early signs may include: / poorer recovery after exercise/ persistent fatigue/ sleep disturbances/ increased abdominal fat/ reduced mental clarity Detecting these changes allows for intervention before aging-related pathologies develop. The biological terrain determines the body's response Before thinking about supplements or therapies, it is essential to build an organism capable of responding correctly. This biological terrain depends on factors such as muscle mass, nutrition, metabolism, microbiota, sleep quality, and stress management. No intervention achieves its maximum potential if these pillars are not present. Adaptive capacity is one of the best indicators of health Another key concept was biological resilience, or the body's ability to regain balance after physical exertion, an infection, or a stressful situation. Over the years, this capacity decreases progressively, becoming one of the first indicators of functional aging. Muscle, metabolism, and inflammation are part of the same system The session also addressed the close relationship between muscle mass, insulin sensitivity, and low-grade chronic inflammation. When visceral fat increases and muscle mass decreases, a vicious cycle can begin that promotes: / insulin resistance/ lower energy production/ loss of physical capacity/ sustained inflammation Therefore, preserving muscle is one of the most important strategies for fostering healthy aging. NAD: another piece of the longevity puzzle After understanding the physiological basis of aging, Dr. Pinilla explained the role of NAD. This molecule participates in processes related to cellular energy production, mitochondrial function, DNA repair, cellular homeostasis, and stress response. However, she insisted that NAD should not be seen as an isolated solution, but rather as a tool that gains significance once habits are already established. Supplementation must be integrated into a global strategy The training concluded by reiterating that the healthcare professional's role is to individualize every case. Before recommending any supplement, it is necessary to assess aspects such as: / sleep quality/ body composition/ stress level/ metabolic health/ patient goals Only after such an assessment does it make sense to integrate support strategies like NAD+ Pro. Key conclusions Functional longevity consists of preserving physical, cognitive, and metabolic capacity for as long as possible. Aging begins long before disease appears, so identifying the loss of resilience allows for early action. Muscle mass, metabolism, sleep, and inflammation control remain the fundamental pillars for healthy aging. NAD participates in numerous processes related to energy production and cellular adaptation, but its efficacy always depends on the patient's physiological context. Ultimately, the best longevity strategy remains building a solid biological terrain first and using supplementation as a support tool within a comprehensive approach.
