a> A biomarker (short for biological marker) is an objective measure that captures what is happening in a cell or an organism at a given moment.

b> Example of a biomarker is your fasting blood glucose, to check the health of your pancreas.

c> If there is no biomarker to monitor as a measure of effectiveness, it doesn’t mean you shouldn’t take the supplement or medication; it just means you may need to be more intentional about monitoring results in other ways.
