Coffee wears off faster, the day feels longer, and there's little left for the things that matter to you. You may have heard the sentence before: your values are all normal. For many of our patients, that was exactly where the real search began. Fatigue isn't a diagnosis – it's a signal. Behind it can be an iron deficit, a thyroid that only looks unremarkable on paper, a micronutrient shortfall, a hormonal shift or exhausted cellular energy. Our job is to decode that signal with diagnostics that go noticeably further than a standard lab.

[ ### Iron & ferritin Including the grey zone. An iron level at the lower end of normal can already cause fatigue. Mehr erfahren ](/en/patient-info/conditions/iron-deficiency)[ ### Thyroid Including fT3, fT4 and antibodies – not just TSH. A frequently overlooked cause of lasting fatigue. Mehr erfahren ](/en/general-practice/thyroid)[ ### Micronutrients Vitamin D, B12, magnesium, zinc and more. Where standard labs stop, we take a closer look. Mehr erfahren ](/en/private-practice/longevity/micronutrient-analysis)[ ### Hormones For women and men. Perimenopause, low testosterone or shifts in cortisol strongly shape your energy. Mehr erfahren ](/en/private-practice/longevity/bhrt)[ ### Cellular energy & mitochondria The power plants of your cells. When they falter, even the best sleep won't fix it. Mehr erfahren ](/en/private-practice/longevity/nad-therapy)[ ### Extended lab diagnostics Where indicated: inflammatory markers, metabolism, functional parameters beyond the standard panel. Mehr erfahren ](/en/private-practice/longevity/lab-diagnostics) ## What then helps: your individual plan Only once the findings are on the table do we talk about therapy. Depending on the cause, your plan can look very different – from targeted supplementation to infusion and oxygen therapies. What we do not do: sell one-size-fits-all cures. What we do: measure, understand, treat specifically and follow up. [ ### Vitamin & NAD+ infusions Targeted supplementation when oral intake isn't enough or a faster effect is needed. Mehr erfahren ](/en/private-practice/longevity/vitamin-infusions)[ ### IHHT cell training Interval oxygen training to help regenerate mitochondria. Mehr erfahren ](/en/private-practice/longevity/ihht)[ ### Ozone autohemotherapy The classic autohemotherapy with medical ozone for circulation and cellular metabolism. Mehr erfahren ](/en/private-practice/longevity/ozone-autohemotherapy) ## How it works 01 ### First consultation We listen. Your story, your everyday life, your previous findings. 02 ### Diagnostics Blood work and examinations in one visit, optionally combined with a heart and vascular check. 03 ### Review meeting You understand your values, we agree on the plan together and track your progress. ## Frequently asked questions ### What does the fatigue work-up cost? ### I have statutory insurance. Can I still come? ### How quickly can I get an appointment? ### Isn't a normal check-up enough? ## The first step: a conversation. Book online or call us at +49 8022 3678.
