Minerals such as Potassium, Magnesium, Calcium, and Phosphorus are essential inorganic elements required for various physiological functions in the human body. Potassium is crucial for nerve transmission and muscle contraction. Magnesium is involved in over 300 enzymatic reactions, including energy production. Calcium is vital for bone and teeth formation, blood clotting, and muscle function. Phosphorus is a key component of DNA, RNA, and ATP, and is important for bone health. These minerals are commonly found in foods like fruits, vegetables, dairy, nuts, and meats. They are not organic compounds but elemental minerals that can form salts in the body. Their bioavailability depends on the food source and interactions with other nutrients. In food science, they contribute to the nutritional profile of spices and food products. They support electrolyte balance, skeletal structure, and metabolic processes when consumed in appropriate dietary amounts.
