How to Stay Strong, Sharp, and Energized as You Age: A Functional Medicine Look at Healthy Aging
Episode Summary
Colin Renaud, PA-C hosts Dr. Sasha Rose, ND, for a live conversation about what it actually takes to stay strong, sharp, and energized with age. They draw the line between lifespan and healthspan: functional medicine is not just interested in keeping somebody alive, but in how well they are living, so they can still be in the gym, on the pickleball court, or on the floor with grandchildren in their 70s and 80s. The discussion covers why muscle is one of the biggest anti-aging organs in the body, how a fall becomes the beginning of the end when strength, balance, and bone health have quietly eroded, and why insulin resistance of any kind ages cells at a molecular level. Colin explains how a man with classic low testosterone symptoms gets dismissed because a level of 350 sits inside the 300 to 1,200 reference range, when the literature points to an optimal level of at least 500 to 600. Dr. Rose describes patients told to lower their expectations after basic labs come back normal, and how Med Matrix instead runs a comprehensive panel of over 80 biomarkers plus an InBody body composition scan on every new patient. The episode closes with a rapid true or false anti-aging game covering muscle loss after age 30, continuous glucose monitors, chronic stress, loneliness, and genetics.

Quotable Moments
“we're not just interested in keeping somebody alive for a certain period of time, but how well are they living while they're living?”
“a fall is often unfortunately kind of the beginning of the end”
“muscle is really one of the biggest anti-aging organs in your body. The more you have, the longer you will live.”
“insulin resistance of any kind will automatically age your cells at a molecular level.”
“normal labs doesn't really mean the same thing I think in a conventional medical setting as it does in a functional medicine setting.”

Healthy Aging FAQ
No. Colin Renaud, PA-C explains that because these symptoms are so common, people assume they are supposed to happen, but common does not mean optimal. Functional medicine asks what systems are actually changing underneath, blood sugar, hormones, thyroid, sleep, inflammation, gut health, and nutrient status, instead of writing the decline off as age and telling patients to lower their expectations.
Colin Renaud, PA-C calls muscle one of the biggest anti-aging organs in the body: the more you have, the longer you will live. Dr. Sasha Rose adds that muscle strength directly drives mobility, balance, and bone health, and when those erode, a fall is often the beginning of the end for an older person's independence. Muscle also regulates blood sugar, insulin sensitivity, and overall metabolism.
Dr. Sasha Rose notes that routine panels are far less comprehensive than a functional medicine panel, and even shared markers get interpreted differently: standard ranges are not optimal ranges. Colin Renaud, PA-C gives the classic example of a man with low testosterone symptoms and a level of 350. That sits inside the 300 to 1,200 reference range, so he gets dismissed, even though the literature points to an optimal level of at least 500 to 600.
No. In the episode's true or false game, both clinicians answered false. Cardio alone does not preserve muscle. Colin Renaud, PA-C would rather patients lift something or do body weight and resistance work, paired with adequate quality protein, because muscle naturally declines every year after age 30 unless you actively work to keep it.
False, false, false, in Dr. Sasha Rose's words. Both clinicians care for patients in their 70s and 80s who are actively improving, and Dr. Rose stresses that you still deserve to age well no matter what decade you are in. That said, the younger somebody starts thinking about healthy aging, the better they are going to live.
Dr. Sasha Rose describes the intake: a comprehensive panel of over 80 biomarkers, a full health history, an extensive symptom review, a nutrient assessment, a medication and supplement review, sleep quality and quantity, stress resilience, exercise history, and an InBody body composition scan. From there the team builds a personalized plan covering protein targets, strength training, sleep, blood sugar, stress regulation, hormone optimization, nutrients, and gut health.
