Humans require three macronutrients: carbohydrates (sugar), lipids (fats), and proteins. Chlorine isn't a macronutrient, so it's not one of these options. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulphur (S), magnesium (Mg), and sodium (Na) are some of the other macronutrients (Na).
