Nutrient Density compares vitamins and minerals to calories.
Vitamin D supports bone health and immune function.
Iron supports oxygen transport and energy metabolism.
Magnesium supports muscle contraction, nerve function, and energy production.
Potassium helps maintain fluid balance and supports muscle and nerve function.
B vitamins support energy metabolism, red blood cells, and nervous system function.
