Thyroid Panel
Standard TSH alone misses a lot. These markers reveal how well your thyroid is producing, converting, and delivering active hormone to your cells.

Metabolic Panel
Metabolic health is deeply connected to hormone balance. These markers reveal how your body is managing blood sugar, insulin sensitivity, and cardiovascular risk — often years before disease develops.
Chronic low-grade inflammation is a silent driver of hormone dysregulation, fatigue, and metabolic dysfunction. These markers catch it early.

Adrenal & Key Nutrients
Cortisol dysregulation and nutrient deficiencies are often the hidden roots of fatigue, mood changes, and poor hormone metabolism. These are frequently missed on standard panels.
