welche mineralien braucht der körper — what symptoms are typical?

The human body requires a range of minerals for essential functions. Key minerals include calcium (bones, teeth, muscle contraction), magnesium (energy metabolism, muscle and nerve function), potassium (heart rhythm, blood pressure regulation), sodium (fluid balance, nerve impulses), iron (oxygen transport, blood formation), zinc (immune system, wound healing), iodine (thyroid hormones), and selenium (antioxidant, thyroid function). Typical deficiency symptoms are: calcium deficiency leads to osteoporosis and muscle cramps; magnesium deficiency causes fatigue, muscle twitching, and arrhythmias; potassium deficiency results in weakness and irregular heartbeat; iron deficiency manifests as anemia with pallor and exhaustion; zinc deficiency can cause hair loss and increased infection risk; iodine deficiency leads to goiter and hypothyroidism. The evidence for these relationships is strong, based on decades of clinical research. However, individual needs vary, and a balanced diet usually covers mineral requirements. If a deficiency is suspected, a doctor should be consulted, as blood values and symptoms must be assessed together.
