In this episode of Second Act Sessions, I’m joined by Tom Nikkola, a Certified Strength & Conditioning Specialist (CSCS) who has spent more than two decades helping people build stronger, healthier bodies through fitness, functional nutrition, and personal transformation. While his early work focused on physical performance and metabolic health, he’s now widely respected for his ability to break down complex biochemical topics—like the MTHFR gene mutation and methylation—in a way that’s approachable, empowering, and refreshingly honest.

Many people have never even heard of the MTHFR mutation, yet it’s estimated that up to 40% of the population carries it—often without realizing how much it may be affecting their energy, mood, hormones, detox pathways, and even their ability to recover from stress. Tom helps us understand what MTHFR is, why methylation matters, and how these processes influence so many of the symptoms that midlife women often chalk up to “just aging.”

We dive into how hidden genetic roadblocks can show up as anxiety, brain fog, chronic fatigue, or gut issues—not because of a lack of willpower or mindset, but because of biochemical imbalances that conventional medicine often overlooks.

This conversation is especially meaningful for anyone in their second act—those of us in midlife who want to take ownership of our health and feel empowered to heal at the root. Tom shares clear, science-backed steps, from targeted supplements to lifestyle shifts, that can help restore methylation and support the body’s natural capacity to heal.

Whether you’re brand-new to this topic or, like me, have discovered the MTHFR mutation in your own family, this episode will give you clarity, hope, and practical steps for building a healthier next chapter.
