What is an mcg?

MCG stands for Microgram, which is a unit of measurement commonly used in the field of science and medicine to express very small amounts of a substance. One microgram is equal to one millionth of a gram, or 0.000001 grams.

Micrograms are often used to measure the dosage of medications, vitamins, and minerals, as well as certain toxins and pollutants. It is important to be aware of the specific unit of measurement when dealing with micrograms, as confusion with milligrams (which are 1000 times larger) can lead to significant errors in dosing.

In terms of nutritional labeling, micrograms are often used to indicate the amount of certain nutrients present in a food or supplement, such as vitamin D or iron. It is important to pay attention to these values to ensure that you are meeting your daily nutritional needs.
