Social Anxiety: Biological Roots Beyond PsychoSocial-Emotional Healing

A woman reached out on Instagram asking if I ever talk about social anxiety — particularly in motherhood. This post is for her. And for everyone who has done the emotional work and is still struggling.

🎧 Listen: E55 Pyroluria and Social Anxiety — Discovering the Biological Connection

Most people who come to me with social anxiety have already done a lot of work. Therapy. Journaling. The emotional excavation. They’ve looked at their patterns, addressed the relational wounds — and they’re still anxious in social situations.

What most of them haven’t been told is that social anxiety has biological roots. Ones that don’t show up on standard medical panels. Ones that most practitioners — even good ones — have never been trained to explore.

Here’s what I’ve learned after studying applied quantum biology: when we don’t address the biological layer, even the best psychological work has a ceiling. Not because the emotional work isn’t real or isn’t necessary — it is. But because the body is a system. Coherence has to happen at every level.

What Social Anxiety Actually Looks Like

Social anxiety isn’t just stage fright or introversion. It’s:

•   Intense discomfort doing everyday things — the grocery store, school pickup, a work meeting
•   Heart racing, flushing, a feeling of being unable to handle situations others move through easily
•   A persistent low-level anxiousness that spikes around other people
•   That internal shakiness that feels like it’s just who you are
•   Fear of having an episode in public — which can spiral into avoidance and isolation

It often peaks during high-visibility seasons: early motherhood, a new job, a major life transition. Any time we feel watched or exposed.

And underneath most of it, there are old shame messages running. Shame is different from guilt. Guilt says I made a mistake. Shame says I am the mistake. It operates underground — surfacing as hypervigilance, self-consciousness, and the relentless internal critic that won’t quiet down.

This emotional layer is real. It absolutely needs to be addressed. Shame resilience is central to what I teach in ARC for Women — because healing shame changes how we move through everything else.

But shame work alone won’t get you to full recovery if the body is in a state of biological danger signaling.

Anxiety Is a Signal From the Body

I teach that anxiety — of any kind — is a signal. An accurate communication from the body-mind-soul that something is out of balance. The body is not broken. It is trying to get your attention.

The question is always: to what is the signal pointing?

With social anxiety, the answer is rarely just one thing. It’s layered:

•   Psychosocial-emotional — shame, self-judgment, relational wounds, old subconscious tapes
•   Nutrient deficiencies — particularly zinc and B6, and a condition called pyroluria
•   Metabolic health — blood sugar dysregulation, gut dysfunction, insulin resistance (IBS, hypoglycemia, and social anxiety cluster together more than most realize)
•   Mitochondrial and circadian health — the quantum biology foundation that either supports or undermines everything else

Each layer is workable. Full recovery requires tending to all of them.

Pyroluria: The Biological Root Most Practitioners Miss

If I had to name the single most underdiagnosed contributor to long-standing social anxiety (especially in women), it would be pyroluria.

Pyroluria is a condition of the heme in which the body chronically depletes zinc and vitamin B6. It doesn’t show up on a standard panel. Most conventional practitioners have never heard of it. And yet it has a very recognizable presentation: an inner tension and social anxiety that has been present since childhood, that doesn’t trace back to a specific event or wound, that just feels like this is who I am.

People with pyroluria often don’t appear anxious on the outside. They can push through. They may even be outgoing. But internally there is a constant low hum of unease — a sense of fear or angst that never fully lifts.

Signs that suggest pyroluria may be worth ruling out:

•   Social anxiety or inner tension present since childhood
•   White spots on the fingernail beds
•   Easily internally upset by criticism (even when externally composed)
•   Bouts of depression or nervous exhaustion
•   Frequent fatigue
•   Tendency toward isolation over time
•   Difficulty digesting protein or meat

When a client describes lifelong inner tension alongside social anxiety, and I see white spots on their nails — ruling out pyroluria is one of the first things I want to do.

Testing and Getting Answers

The test is a Kryptopyrrole urine test — simple, self-administered, mailed in. The sample must be frozen. In the US, I use DHA Labs. I do not have an affiliation with DHA Labs, it's just the one that has the capacity to test the frozen urine. You can order it without a physician. Insurance doesn’t typically cover it, but it’s one of the most actionable tests I know of for this presentation.

You can also check B6 and zinc through bloodwork, though B6 is not routinely ordered — you may need to request it specifically. As Dr. Carl Pfeiffer documented in Nutrition and Mental Illness, patients with poor dream recall were consistently deficient in B6. In fact, B6 and zinc deficiencies show up across many anxiety presentations, not just pyroluria.

If you want to start before testing, increasing zinc and B6 through food is low-risk and often informative. A short supplement trial (two to three months) is also reasonable — but I don’t recommend long-term B6 supplementation without confirmed deficiency. You will want to stop any supplementation prior to testing as it can alter your results. 

Food First: Zinc and B6 Sources

I prioritize animal-based sources for both nutrients — more bioavailable, less complicated by antinutrients.

Vitamin B6 is found in good amounts in chicken and turkey, pork, salmon and tuna, eggs, beef, chicken liver, and milk or ricotta cheese. Avocado is also a good source. Sweet potato and spinach contain B6 but are high in oxalates — consume mindfully and seasonally.

Good sources of Zinc:

•   Oysters — one of the highest zinc sources available
•   Lamb
•   Grass-fed beef
•   Eggs
•   Chicken
•   Mushrooms
•   Kefir or yogurt

The Layer That Underpins Everything: Mitochondria and Circadian Biology

Here’s what I didn’t fully understand two years ago when I wrote my first blog on pyroluria — and what changed my clinical approach entirely.

Even when the pyroluria piece is addressed, even when zinc and B6 are optimized, even when the emotional work is being done — if the mitochondria are under-resourced, the body is still in a state of danger signaling. And danger signaling amplifies anxiety at a subcellular level, independent of everything else you’re doing.

The mitochondria are not just energy producers. They are the cell’s master decision-makers about safety. When they don’t have what they need — the right light inputs, circadian rhythm coherence, structured hydration, electron availability — they initiate what’s called the cell danger response. This drives inflammation, dysregulates the nervous system, and creates a physiological environment where anxiety is almost inevitable, regardless of how much emotional work you’ve done.

Circadian misalignment is one of the most chronically under-addressed stressors I see. Our circadian rhythms influence nearly every physiological function — hormone release, immune activity, neurotransmitter production, gut motility, even how we process and respond to emotional threat. When those rhythms are disrupted by artificial light at night, irregular eating patterns, or disconnection from natural light cycles, the nervous system cannot fully down-regulate. The social anxiety that feels psychological may have a significant circadian component.

This is why quantum health strategies — morning light exposure, grounding, reducing artificial light after sunset, eating in alignment with daylight hours — aren’t optional add-ons. They are the biological container in which recovery becomes possible.

And this is why the Food-Mood Anxiety Solutions Course addresses not just what you eat, but when and how — because the timing of food is a circadian signal. It’s information your mitochondria are reading constantly.

What Full Recovery Actually Requires

Social anxiety is fully recoverable. Not just managed — resolved. But the path there requires looking at more than we’ve been taught to address.

Start with the biology: rule out pyroluria, address zinc and B6, support metabolic health, and build the mitochondrial and circadian biology. That work is foundational. Then look at the emotional layer — the shame, the old tapes, the relational wounds. Emotional healing creates greater coherence in the body and helps everything else stick.

It takes time. It takes education and patience. And it is absolutely possible.
