What measurement units are typically used for micronutrients like Iron or Zinc?
Answer
Milligrams (mg) or micrograms (mcg)
Micronutrients are defined by the small quantities the body requires for optimal function, differentiating them significantly from macronutrients which are measured in grams. Specifically, vitamins and minerals are quantified using much smaller measures, such as milligrams (mg) or micrograms (mcg). For instance, a daily need for Iron might only be in the range of 8 to 18 milligrams, contrasting sharply with the hundreds of grams of carbohydrates often consumed daily. This small required amount underscores their regulatory role rather than their primary caloric contribution.
