Percentages are the share of the FDA Daily Value for adults and children 4 and over, worked out from Subway’s published amounts (how % Daily Value works). A dash means Subway does not publish that value for this size.
Using the FDA’s rule of thumb that 5% of the Daily Value or less per serving is low and 20% or more is high, the 6" size is low in fat, saturated fat and cholesterol. Add it up with other items in the Subway nutrition calculator.

Allergens from the allergen chart row "Hearty Multigrain".
Subway builds its allergen chart from information supplied by its approved manufacturers and warns that recipes can change before the chart is updated; some regional and promotional items are not covered. Ingredients can touch each other during preparation, which the chart does not show, so guests with a food allergy should tell the sandwich artist. Wheat and gluten share one column because every gluten-containing Subway item contains wheat. Cookies may contact nut-containing cookies because of how they are displayed. Items marked as containing only highly refined oil from an allergen source are exempt from FDA allergen labeling. The gluten-free bread is made in a gluten-free facility, but other items containing gluten share equipment in the restaurant, so Subway cannot guarantee any item is entirely gluten-free. The chart also flags sulfites and added nitrites/nitrates.
