Begin with serving size
Every number on the panel is tied to the listed serving. Compare products only after checking whether the serving is one capsule, several capsules, a scoop, or another amount.
Read amount and % Daily Value separately
Amount per serving tells you how much is present. Percent Daily Value is a reference point for the general population; it is not a personalized target. Some ingredients do not have an established Daily Value.
Keep the rest of the label in view
Directions, other ingredients, allergen statements, cautions, storage instructions, and contact information can be as important as the front-panel name.
