Low Sodium Subway: Best 6" Builds Ranked by Sodium

Subway is the chain where low-sodium ordering is most possible — and most often fumbled. Because every sandwich is built to order, a 6” can land anywhere from 280 mg to over 1,500 mg of sodium depending on three choices: the filling, the cheese, and the sauce.

Low sodium Subway orders share a pattern: lean single-meat fillings, no cured-meat stacks, one cheese or none, and a low-sodium sauce. This guide ranks every standard 6” build by sodium, then shows the math so you can improvise your own.

Not medical advice. Sodium needs vary. Subway nutrition varies heavily by bread, cheese, veggies, and sauce — rebuild your exact order in Subway’s official nutrition tool before relying on any figure.

Every 6” build, ranked by sodium

Figures are typical US 6” builds with standard bread and veggies, from Subway’s published nutrition data:

6” Build	Sodium	Calories	Protein
Veggie Delite	280 mg	230	8 g
Tuna	640 mg	480	20 g
Oven Roasted Chicken	650 mg	320	23 g
Rotisserie-Style Chicken	670 mg	350	29 g
Roast Beef	710 mg	320	25 g
Turkey Breast (no cheese)	760 mg	290	18 g
Black Forest Ham	800 mg	290	18 g
Steak & Cheese	1,050 mg	380	24 g
Meatball Marinara	1,130 mg	480	21 g
Italian B.M.T.	1,270 mg	410	20 g
Cold Cut Combo	1,290 mg	360	16 g
Spicy Italian	1,520 mg	480	20 g

Three tiers jump out:

• Under 800 mg — veggie, chicken, roast beef, turkey, tuna. A full meal with a side and drink stays under 900 mg. This is the low-sodium zone.
• 1,000–1,300 mg — steak, meatball, and the cured-meat combos. Half a strict day’s budget in one sandwich.
• 1,500 mg+ — the Spicy Italian alone, before chips and a drink. Avoid on a sodium-conscious day.

The three levers that move your total

Subway sodium is modular. Control these and you control the meal.

1. Size: a footlong is a doubling

The Footlong Turkey (no cheese) hits 1,520 mg — exactly double its 6”. If you want more food, a second 6” the next day is the sodium-friendlier move; a footlong at lunch plus a normal dinner blows most budgets. If you do order a footlong, make it one of the under-800 mg fillings.

2. Cheese: +150–200 mg

Cheese	Sodium added
Provolone	~150 mg
Pepperjack	~180 mg
American	~200 mg

Skipping cheese is the single fastest cut at Subway — and it’s why the turkey build above is listed “no cheese.”

3. Sauce: 0–240 mg per serving

Sauce	Sodium
Oil & Vinegar	0 mg
Mustard	85 mg
Mayonnaise	85 mg
Sweet Onion	190 mg
Chipotle Southwest	190 mg
Ranch	240 mg

Oil & vinegar and mustard are the free wins. Ranch and the sweet/creamy sauces quietly cost as much as a slice of cheese.

The real trap: cured-meat stacks

The four worst builds — Spicy Italian (1,520 mg), Cold Cut Combo (1,290 mg), Italian B.M.T. (1,270 mg), Meatball Marinara (1,130 mg) — share one trait: multiple cured or processed meats. Pepperoni, salami, bologna, and meatballs are salt-preserved by design, and stacking two or three kinds multiplies sodium before cheese or sauce enter the picture.

Rule of thumb: one lean meat, not three cured ones. Rotisserie chicken, roast beef, oven-roasted chicken, and turkey all build a satisfying sandwich in the 650–800 mg range.

Three ready-to-order meal builds

From our Subway guide meal plans — exact orders with totals:

Meal	Order	Sodium	Calories
Breakfast	6” Oven Roasted Chicken + mustard + bottled water	735 mg	325
Lunch	6” Turkey Breast, no cheese + mustard + apple slices + diet soda	885 mg	320
Dinner	6” Rotisserie-Style Chicken + mustard + apple slices + bottled water	755 mg	390

Note the side strategy: apple slices add 0 mg, while a bag of potato chips adds 250 mg. At Subway, the side is the second sandwich decision.

Speaker-line checklist

• 6”, not footlong (or split the footlong across two meals)
• One lean filling: chicken, roast beef, or turkey
• No cheese — or provolone if you must (+150 mg)
• Mustard or oil & vinegar
• Load the free veggies: lettuce, tomatoes, cucumbers, peppers, onions
• Apple slices, not chips
• Water or diet soda (0–40 mg)

FAQ

Is Subway low sodium? It can be — it’s one of the few chains where a full meal under 800 mg is easy, because you control every component. But the default builds with cured meats, cheese, and creamy sauces run 1,300–2,000+ mg. The range is wider than any other major chain.

What is the lowest sodium sub at Subway? The 6” Veggie Delite at 280 mg. For a protein sub, the 6” Oven Roasted Chicken (650 mg) and 6” Tuna (640 mg) are the floor. Add cheese to any of them and you give back 150–200 mg.

Which Subway bread is lowest in sodium? Bread is baked into every build’s number and varies less than people expect — the filling, cheese, and sauce choices matter far more. Check Subway’s nutrition tool if you’re comparing two specific breads for your build.

Is a Subway salad lower sodium than a sub? Usually slightly, since you drop the bread — but the meat and dressing still dominate. A Spicy Italian salad with ranch is still a 1,500+ mg bowl. Build salads by the same rules: lean protein, light dressing on the side.

How does Subway compare to other chains for sodium? Its best builds (280–800 mg) beat almost every burger chain’s floor. Its worst builds are as bad as anything in fast food. See our ranked picks across 15 chains for context.
