How to use the label

Multiply sodium per serving by the number of servings you eat. A 300 mg serving becomes 450 mg when you eat 1.5 servings.

The 2,300 mg Daily Value is a general label reference, not a personal target. More about sodium.

Compare the portion you will eat

Imagine choosing between two soups. The label alone does not tell the whole story.

Soup A

450 mg sodium

The label says 300 mg per serving. Eating 1.5 servings gives you 300 × 1.5 = 450 mg.

Soup B

500 mg sodium

The label says 250 mg per serving. Eating two servings gives you 250 × 2 = 500 mg.

Soup B starts with the lower label number, but the larger portion has more sodium. Include toppings or sides separately if they are not covered by the label.
