Autoimmune Thyroid Risk
Genetic predisposition to Hashimoto's or Graves' varies widely. If you're in the higher-risk group, early antibody monitoring can catch the process years before full disease expression—when lifestyle interventions still have leverage.
What this measures
How your DNA shapes autoimmune thyroid risk.
Autoimmune thyroid conditions (Hashimoto's, Graves') develop when the immune system mistakes thyroid tissue for a threat and attacks it. HLA-DR3, HLA-DR4, CTLA4 (immune-checkpoint regulator), PTPN22 (T-cell regulator), and FOXP3 (regulatory T-cell function) sit at the center of the immune dysregulation that drives the pattern.
Carriers of HLA-DR3 or HLA-DR4 variants combined with CTLA4 or PTPN22 reduced-function variants are associated with elevated autoimmune thyroid risk — both Hashimoto's (the most common driver of hypothyroidism) and Graves' (autoimmune hyperthyroidism). Carriers of typical-function variants in this network are associated with lower lifetime risk. The genetic susceptibility sets the necessary condition; environmental triggers shape whether the response actually activates.
Stress, infection, pregnancy, and certain nutritional patterns (excess iodine, low selenium, gluten in susceptible carriers) are involved in triggering active disease. Selenium is essential for thyroid antibody regulation. Vitamin D modulates immune tolerance. Gut barrier integrity influences immune reactivity broadly. Early thyroid antibody screening (TPO, TgAb) catches the pattern before clinical disease develops.
The "thyroid runs in my family" framing often hides a specific autoimmune-pattern variant set that catches up to clients in midlife. Which HLA-DR/CTLA4/PTPN22 pattern you carry decides whether thyroid monitoring belongs in routine annual labs or whether more frequent surveillance and proactive immune support is worth the effort.

Cortisol Production
Some people run naturally high on cortisol; others trend low. Neither is inherently bad—but each benefits from different stress-management strategies. High producers need more active recovery; low producers may need adaptogen support. One-size-fits-all stress advice ignores this completely.
Read insight →Cortisol Receptor Sensitivity
Same cortisol level, very different felt experience. High receptor sensitivity means stress hits harder even when cortisol is "normal." This explains why some people thrive in chaos while others burn out—and it's not about being weak. It's about wiring.
Read insight →DIO1 Activity
DIO1 handles the body-wide conversion of inactive T4 into active T3. Reduced activity is a common reason for persistent hypothyroid symptoms—fatigue, weight gain, cold intolerance—even when TSH looks "normal." Standard testing misses this entirely.
Read insight →DIO2 Activity
DIO2 produces T3 specifically in the brain and muscles. Low activity is one of the most common causes of brain fog and cold hands on standard thyroid treatment that looks fine on paper. If your labs are normal but you still feel terrible, this is often why.
Read insight →Dihydrotestosterone (DHT) Levels
DHT is the more potent downstream product of testosterone. High converters may see effects on hair loss, prostate health, or skin—and often benefit from DHT-blocking strategies before symptoms become problems. Low converters rarely need to worry about it.
Read insight →Estrogen Metabolism
Your liver processes estrogen through multiple pathways—some produce protective metabolites, others produce more aggressive ones. This ratio matters for long-term health and explains why some people feel great on the same hormone levels that cause problems for others. Cruciferous vegetables and targeted supplements can shift the balance.
