Hormone Testing Explained: Blood Work vs Dutch vs Hormone Zoomer (Cortisol, Toxins, Perimenopause) | Period Besties
In this Period Besties Podcast episode, hosts welcome Maria of Rupp Wellness to explain hormone testing options and why many people with clear symptoms still get “normal” results on standard blood work.
Maria compares blood labs with functional testing like the Hormone Zoomer (which she calls the gold standard), emphasizing hormone metabolites, multi-point saliva cortisol patterns, and screening for endocrine disruptors and toxins such as BPA, atrazine, triclosan, and glyphosate.
The conversation covers how cortisol, insulin resistance, gut health, and toxins can drive hormone imbalance, plus connections to sleep, melatonin, testosterone, thyroid function, and supplement quality. They discuss budget-friendly approaches, advocating for foundational lifestyle changes, targeted labs (including thyroid panels and vitamin D), and careful testing before adding hormones, especially in perimenopause.
