Magnesium lines as filed

Swanson Magnesium Watermelon retains 2 magnesium-related rows in NIH DSLD 308655, including 2 rows selected for the primary serving, from label 2024-03-22, examined 2026-09-13.

Package arithmetic · observed inputs, computed totals

What the package works out to

Swanson Magnesium Watermelon works out to 120 days per package at the label's own serving and filed frequency of 1 servings per day, according to label 2024-03-22, calculated 2026-09-13.

Days = filed servings per container ÷ filed servings per day. If the label gives a frequency range, the largest frequency gives the shortest duration. Cost per serving = observed item price ÷ filed servings; cost per label-day multiplies this by the filed frequency. This follows the label's own instructions; it is package arithmetic, not intake advice.
