These minerals play vital roles in human nutrition and are commonly found in various food sources including spices. Calcium (Ca) is the most abundant mineral in the body, essential for bone and teeth formation, muscle function, and nerve signaling. Magnesium (Mg) acts as a cofactor in over 300 enzymatic reactions, supporting energy production and muscle relaxation. Potassium (K) is critical for maintaining fluid balance, nerve impulses, and heart rhythm. Iron (Fe) is a key component of hemoglobin, facilitating oxygen transport in the blood. In the context of spices and food compounds, these minerals contribute to the overall nutritional profile, potentially enhancing health benefits when consumed as part of a balanced diet. Their bioavailability can vary depending on the food matrix and presence of other compounds such as phytates or vitamin C.
