Hormones
Endocrine signaling that regulates the whole body.
Overview
The endocrine system uses hormones — chemical messengers like insulin, thyroid hormone, cortisol, and sex hormones — to coordinate metabolism, growth, reproduction, mood, and stress across the whole body.
Why it matters
Hormonal balance influences energy, body composition, bone, mood, and reproduction. Both deficiency and excess matter, and interpretation depends heavily on context — making careful measurement essential and over-treatment a real risk.

Frequently asked questions
Should I get my hormones 'optimized'?
Genuine deficiencies deserve treatment, but pushing hormones above normal ranges carries real risks without clear benefit. Context and confirmation matter more than a single number.
Why measure hormones in the morning?
Several hormones, including testosterone and cortisol, follow a daily rhythm, so timing and repeat testing are needed for an accurate picture.
