If you feel stressed, tired, anxious or overwhelmed it could be a sign your nervous system is strained. Minerals include electrolytes, which provide the energy you need to get through the day, as well as buffer the effects of stress. The Mineral & Metals Test takes a comprehensive look at adrenal function; the body's stress support system, as well as toxic metal exposure. If mineral reserves are low, electrolytes imbalanced or if you've been exposed to high levels of toxic metals you won't be able to deal with stress effectively and may experience a range of health challenges.
