Beyond the Sequence

Join Sarah Amidon, RD and Amanda Archibald, RD, 2 DNA Dietitians, for a conversation about MTHFR, methylation, nutrigenomics, and the questions you’re afraid to ask—or can’t seem to get a straight answer to and are subject to crowdsourcing your health.

What if protecting an athlete’s future began before the first major injury? In this episode, we go beyond traditional performance metrics to explore concussion, cumulative training load, recovery, injury risk, and the emerging role of genomics in building a more individualized approach to athlete health. We also challenge the assumption that being fit always means being healthy—examining how excessive training, inadequate recovery, oxidative stress, and shifts in cardiovascular markers can create hidden risks—even in highly conditioned athletes. By looking beyond performance alone, we explore how genomics, biomarkers, and training data can help identify risk, personalize recovery, prevent injury, and build a safer, more sustainable path to long-term athletic performance and longevity.

Hormones don’t work in isolation. They work in systems. In this episode of Beyond the Sequence, Sarah and Amanda explore why hormones are far more complex than simply being "too high" or "too low." They unpack the concept of hormone signaling, explaining how production, conversion, transport, receptor function, and detoxification all influence whether hormones can effectively deliver their message. Through discussions on thyroid health, estrogen, testosterone, stress, environmental toxins, sports performance, and genomics, they reveal how understanding the body's signaling pathways can uncover the root causes behind fatigue, poor recovery, mood changes, and metabolic dysfunction—and why personalized, genomics-informed care offers a more complete path to better health.

In this episode of Beyond the Sequence, Sarah and Amanda challenge one of the biggest misconceptions in health: that cholesterol is the problem. Instead, they explore cholesterol as a vital signaling molecule involved in hormone production, immune function, brain health, and cellular repair. Through the lens of genomics, they discuss how patterns like inflammation, stress, digestion, liver function, recovery, and genetics can influence cholesterol levels, helping listeners move beyond treating lab numbers to understanding what their body is actually trying to communicate.

In this episode, Sarah and Amanda dive into one of the most common — and misunderstood — struggles in midlife health: sleep disruption. From feeling “tired but wired” to waking at 3 a.m. unable to fall back asleep, they unpack why sleep problems are rarely just about sleep itself.

Together, they explore the deeper biology behind insomnia, including cortisol dysregulation, nervous system overload, blood sugar instability, nutrient depletion, inflammation, and the genetic pathways that influence stress resilience, rumination, hormone balance, and neurotransmitter production.

The conversation connects sleep to real-world patterns they’re seeing clinically in both midlife adults and athletes — from burnout and anxiety to overtraining, under-fueling, hormone shifts, and chronic stress. They also discuss lifestyle factors like blue light exposure, birth control, caffeine, alcohol, and nutrient deficiencies can quietly impact recovery and sleep quality.

We’re hitting pause on our usual series to dive into a topic that’s been buzzing everywhere—APOE and its connection to Alzheimer’s risk.

In this unfiltered, free-flowing episode, Sarah and Amanda break down what APOE actually means (without the fear-based hype), why the “risk gene” conversation is often taken out of context, and what really matters when it comes to protecting your brain.

From decoding the infamous “2-3-4” gene variants to explaining APOE as your brain’s cholesterol delivery system, this episode connects the dots between genetics, environment, and everyday lifestyle choices. You’ll hear why genes are not a diagnosis, how nutrient status, digestion, sleep, stress, and detoxification all influence cognitive health—and why focusing on cholesterol alone misses the bigger picture.

In this episode of Beyond the Sequence, we’re diving into a question so many people ask in their 40s and beyond:

“Why does my body suddenly feel like it’s falling apart?”

Is it really just aging… or is something deeper going on?

We unpack the hidden drivers behind midlife “breakdown”—from hormone shifts and stress overload to nutrient depletion, mitochondrial dysfunction, and nervous system strain. This isn’t about accepting decline—it’s about understanding adaptation.

The bottom line? Your body isn’t betraying you—it’s adapting to a new set of demands.

And once you understand the “why,” you can finally start rebuilding.

In this episode, Sarah and Amanda explore the intricate relationship between sports performance, recovery, nutrition, and genomics. They discuss how hypoxic environments like those seen in the Winter Olympics can contribute to faster tissue breakdown when combined with genetic predisposition, the crucial role of intentional recovery in athletic performance, and how nutrition combined with genetics can help you prevent injuries. The conversation also delves into the impact of hormones and mental health on athlete performance, as well as the hidden loads and stressors that can lead to injuries. Get the edge over your competition with these insights!

Why are so many bodies breaking—even when people are “doing everything right”? Drawing from real clinical patterns and genomics, they unpack how chronic stress, depleted energy systems, and modern life overload the body’s ability to repair itself—often long before labs or diagnoses flag a problem.

This conversation sets the stage for a new series examining why recovery is failing, how stress and inflammation silently drive breakdown, and what the body has been trying to tell us all along.

A candid conversation about the explosion of genomic testing… and the confusion that comes with it. We’re breaking down how the public can tell who is actually qualified to interpret DNA results — and how to avoid the growing wave of misinformation and well-intended but harmful advice. From extreme diets and supplement stacks to AI-generated recommendations, this episode is aims to protect, clarify, and empower.
