Do you regularly feel tired and lacking in drive despite getting enough sleep? Laboratory analyses can provide clues about possible nutrient deficiencies or hormonal factors.

Chronic fatigue can be related to a deficiency in vitamin B12, D or iron, as well as elevated cortisol caused by stress. Laboratory tests provide clues about corresponding deficiencies or imbalances.
For persistent exhaustion, a comprehensive nutrient analysis can capture several factors at once. Several causes or symptoms can be considered together, so the investigation doesn't stop at a single trigger.
These recommendations are for general orientation and do not replace a medical diagnosis or treatment. If you have symptoms or unusual lab values, you should consult a medical professional.
