Your Genes by Design Podcast with Lauri Wakefield

00:31 — Welcome And Series Context
Hi, I’m Lauri. Thanks so much for joining me today.

This is the first episode in a new rotation where we explore how your genes influence multiple layers of midlife health — not just glucose, but detox, hormones, gut health, brain clarity, heart health, and bone strength.

The title of today’s episode is How Your Body Clears Hormones, Stress Metabolites, and Everyday Toxins After 45.

Today we’re going to look at something almost every woman over 45 experiences, even if she doesn’t yet have words for it — how well, or how slowly, your body clears things out.

Not just environmental toxins, but stress chemicals, estrogen metabolites, caffeine, alcohol, and the byproducts of everyday metabolism.

This process is shaped by your detox and methylation pathways — and by the genes behind them.

01:21 — How Detox Shows Up In Everyday Life
One of the most common midlife experiences is the feeling of being slowed down on the inside. This doesn’t happen to every woman, but it’s very common.

As hormones shift and detox pathways change, some women become more sensitive to supplements, caffeine, alcohol, or fragrances — while others don’t notice much change at all.

If you are more sensitive now, it’s not your imagination.

Your detox and methylation systems — the pathways that help turn over hormones, neurotransmitters, and environmental exposures — simply feel the weight of midlife more than they did in your twenties and thirties.

And your genes can help explain why.

02:03 — Why Detox Matters More After 45
Some women naturally move estrogen through detox pathways more efficiently. Some clear stress hormones quickly. Some are more sensitive to chemicals in their environment. Some need more B vitamins to keep those pathways moving smoothly.

When you understand your own traits, many of these patterns start to make sense.

This matters in midlife because this phase of life brings several changes that increase the demand on detox and methylation.

First, estrogen changes. Even though total estrogen levels drop, the way your body breaks estrogen down matters more than ever. Some pathways produce more protective metabolites, while others create more inflammatory ones.

Second, stress often increases. Careers, caregiving, and daily responsibilities place a greater load on stress chemistry — especially catecholamine metabolism for women with slower COMT activity.

Third, cellular turnover slows slightly with age. That means your body often benefits from more targeted support — not extremes, but thoughtful nourishment.

Detox isn’t something you do once with a cleanse or a reset. It’s your body’s built-in cleanup system — the constant behind-the-scenes work that keeps things moving and balanced.

03:17 — Genes That Shape Detox And Methylation
Several genes influence how this plays out.

One is COMT. This gene helps clear stress hormones, certain neurotransmitters, and one pathway of estrogen metabolism. A slower COMT variant can mean caffeine hits harder, stress chemicals linger longer, and intense fasting or overtraining feels overwhelming. A faster COMT type clears stress chemicals quickly but may burn through magnesium and B vitamins more easily.

Another important gene is GSTM1, one of your glutathione genes. Some people have a null version, meaning the gene is deleted. This is common and simply means the body relies more on food-based antioxidants like cruciferous vegetables, polyphenols, and vitamin C.

The MTHFD1 gene influences folate metabolism, particularly the step that relies on folinic acid. Certain variants increase the need for this form of folate because the pathway doesn’t move as efficiently. This isn’t about high-dose methylated supplements — it’s about the right form at the right dose.

Another gene is NAT2. This gene helps clear aromatic amines found in tobacco smoke, certain dyes, and charred or fried meats. Slower NAT2 types often benefit from more antioxidants and lower exposure to those compounds.

Each of these genes tells part of your detox story — where things move smoothly, where bottlenecks may appear, and what your body may need more of.

04:55 — Everyday Clues From Your Body
You might notice patterns like not tolerating wine the way you used to, getting headaches from fragrances, feeling like stress stays in your body longer, or having more difficulty with deep, restorative sleep.

None of these mean something is wrong.

They’re simply signals about how your body functions — and your genes help explain why they show up.

05:24 — Supporting Detox Without Extremes
Here’s the practical piece.

Support your pathways consistently, not intensely. Most detox genes respond best to steady daily habits rather than dramatic interventions.

Cruciferous vegetables several times a week can be especially helpful, particularly for GSTM1 null variants or slower estrogen clearance.

Choose folate sources that match your genetics. With certain MTHFD1 variants, folinic acid is often better tolerated than high-dose methylated folate because it supports the pathway without overstimulation.

Be mindful of caffeine and overall stress load if you have a slower COMT variant. Short, lighter morning movement and adequate magnesium can help maintain balance.

Use antioxidants intentionally, not excessively. Vitamin C, berries, olive oil, green tea, and colorful produce provide steady support for detox pathways.

And remember — detox isn’t a cleanse. It’s something your body is already doing every day.

06:24 — Understanding Your Pattern
Your body is constantly processing what you eat, what you breathe, what you feel, and what you experience.

Detox and methylation aren’t extreme systems. They’re part of how your body maintains balance behind the scenes.

After 45, these pathways can feel more noticeable because hormones and genetics are interacting a little differently than they used to.

Once you begin understanding your own patterns, the reactions you’ve been noticing start to make sense — why certain supplements feel stronger, why stress lingers, or why sleep feels different.

And from there, it becomes easier to make choices that support how your body actually works.
