A 500 g restaurant bowl of pho carries about 1,825 mg of sodium. That figure comes from USDA FoodData Central (April 2026 release), which lists pho with meat at 365 mg per 100 g, and it equals 79% of the 2,300 mg Daily Value.
The FDA calls 20% of the Daily Value or more per serving high. This bowl is nearly four times past that line.
Published numbers for a bowl disagree because the serving size changes, not the soup. Most of the sodium sits in the broth, which is seasoned with fish sauce and salt, so how much of it you finish moves the total.
Is pho high in sodium?

Yes, and by a wide margin. A standard restaurant bowl is high in sodium, and the seasoned broth is the reason.
Pho tastes balanced, not salty, so the load hides well. The FDA points out that packaged and prepared foods can be high in sodium whether or not they taste salty.
The American Heart Association says to stay under 2,300 mg a day, with 1,500 mg as the ideal limit for most adults. The FDA counts 20% of the Daily Value or more per serving as high, which works out to 460 mg.
USDA FoodData Central lists pho with meat at 365 mg per 100 g (FDC ID 2707124). A 350 g bowl at that rate comes to about 1,280 mg, calculated from the USDA value.
That is about 56% of the 2,300 mg Daily Value. Hold yourself to the 1,500 mg ideal and it climbs to about 85%.
The AHA puts average U.S. intake above 3,400 mg a day, so a bowl lands on top of an intake that already runs past both limits.
High doesn’t mean off limits. It means the bowl needs to be counted.
Why do published sodium figures for a bowl of pho disagree so much?
Each number rests on a different serving size. USDA FoodData Central lists pho with meat at 365 mg of sodium per 100 g, so the total depends on how many grams are in the bowl.
Nutrition apps built on USDA data list bowls from 333 g (Welling) up to about 735 g. Running the USDA value against a few of those sizes shows how fast the spread opens up.
- About 105 g, roughly half a cup, gives 384 mg. PhillyVoice reported that figure from Real Simple.
- A 333 g bowl gives about 1,215 mg.
- Two cups, or 490 g, comes to about 1,790 mg.
- Three cups, 735 g, lands near 2,680 mg.
That 384 mg is correct for a serving that small. It just isn’t a bowl.
Healthline’s pho overview says one serving of commercially prepared pho can supply about half of a day’s sodium allowance, which matches the 333 g row.
A rough shortcut is 100 mg of sodium per ounce of weight, so a bowl weighing 20 oz (about 567 g) runs near 2,070 mg.
If a published range doesn’t say how much the bowl weighs, throw it out. Multiply 365 mg by the bowl’s grams divided by 100, or use the restaurant’s own nutrition panel when it posts one.
The USDA value is an average. A shop that seasons heavily lands above it, and the average can’t tell you which shops those are.
Where does the sodium in pho come from?

The broth seasoning supplies most of it, usually fish sauce and salt, with a bouillon base in some shops. Hoisin and sriracha add a smaller amount once the bowl is on the table.
| Source | Sodium | Where it enters |
|---|---|---|
| Fish sauce | 1,413 mg per tablespoon (USDA) | Broth seasoning |
| Pho bouillon base | 600 mg per teaspoon (Better Than Bouillon label) | Shortcut broth |
| Hoisin sauce | 258 mg per tablespoon (USDA) | Table sauce |
| Sriracha | 138 mg per teaspoon (USDA) | Table sauce |
| MSG | About one third of table salt’s sodium by weight | Some broths and seasoning packets |
Everything solid in the bowl carries far less than the liquid does. That goes for the sliced beef, the herbs, the bean sprouts and the rice noodles in pho.
Fish sauce
According to USDA FoodData Central, one tablespoon holds about 1,413 mg of sodium, which is 61% of the 2,300 mg Daily Value.
Pho recipes call for it by the tablespoon, so a few spoonfuls in one pot add up quickly.
A-Sha’s spicy beef pho cup lists fish sauce among its ingredients and reads 900 mg per cup on the label.
Broth seasoning and pho base
The label on the Better Than Bouillon Organic Beef Pho Base gives 600 mg of sodium per teaspoon, and one teaspoon goes into 8 oz of water. Salt is the second ingredient, right behind the beef and beef stock.
Three cups of broth at that ratio carry 1,800 mg before any noodles go in.
Hoisin and sriracha at the table
One tablespoon of hoisin plus two teaspoons of sriracha adds about 530 mg, or 23% of the Daily Value.
On the 350 g bowl from earlier, that pushes the total to about 1,810 mg, or 79% of the Daily Value.
MSG

MSG isn’t the main source.
The International Glutamate Information Service says MSG has about one third the sodium of table salt, so an “MSG-free” label says little about total sodium.
Snapdragon’s chicken pho cup lists salt first in its soup base, ahead of yeast extract and the flavor enhancers, and it carries 840 mg.
Which pho has the least sodium?

Homemade, made with a low-sodium stock, because you control the seasoning. Restaurant bowls and instant cups both sit well above the FDA’s 20% Daily Value line for a high-sodium food.
Where instant cups and homemade land
Instant cups aren’t a low-sodium shortcut. Snapdragon’s beef cup reads 780 mg (34% of the Daily Value) and its chicken cup reads 840 mg (37%).
| Type | Sodium per bowl | What sets the number |
|---|---|---|
| Restaurant, 350 to 750 g | About 1,280 to 2,740 mg (calculated from USDA) | Broth seasoning and bowl size |
| Instant cup, beef | 780 to 900 mg (Snapdragon and A-Sha labels) | Seasoning packet with soy sauce powder |
| Instant cup, chicken | 840 to 850 mg (Snapdragon and A-Sha labels) | Seasoning packet |
| Homemade | No standard value | Your stock and your fish sauce |
Healthline’s pho overview suggests making the bone broth from scratch or buying a lower-sodium stock.
Homemade only wins if the fish sauce gets measured too, since one tablespoon alone adds 1,413 mg.
Does the protein matter?
Less than the seasoning does.
When you compare beef pho and chicken pho, the gap comes mostly from the seasoning blend. In Snapdragon’s instant line the beef cup reads 60 mg lower than the chicken cup (780 mg against 840 mg), so the meat isn’t what sets the order. Only the beef base lists soy sauce powder.
Vegetarian pho swaps the stock and keeps the seasoning step. Check the label or ask, because salt and soy-based sauces put sodium into any broth.
Does finishing the broth change how much sodium you eat?
It does. In Asian-style noodle soups the soup base carries a large share of the sodium, so leaving broth behind cuts intake by a range, not by a fixed amount.
Hong Kong’s Consumer Council tested noodles and soup base separately in 2018 and traced the problem to the soup base. Skipping the soup cut sodium by 18% to 68%, depending on the dish.
The city’s Centre for Food Safety found that about half of the sodium in a ramen bowl came from the soup (Food Safety Focus, January 2020).
The Consumer Council test included one pho dish (pho with thin sliced beef), but it published a single range across all dishes with no pho-specific breakdown. The Centre for Food Safety figure is for ramen. Both are proxies for pho. They agree on direction and differ on size, which is why the range is so wide.
Applied to the 350 g bowl from the first section, the Consumer Council range puts a bowl without its broth at roughly 410 to 1,050 mg. Treat that as an extrapolation, not a measurement.
In practice, stop sipping once the noodles and beef are gone. Whatever is left is broth alone.
Speed matters a little too. The Centre for Food Safety advises eating the noodles quickly, before they soak up more of the soup.
Who should limit pho for sodium, and when is it not a concern?

Anyone with high blood pressure or kidney disease should count every bowl, and heart failure belongs on that list. A healthy adult can fit one into a day that is otherwise low in sodium. Heavy sweaters follow a different rule altogether.
People who should count every bowl
For high blood pressure, the AHA says cutting back by 1,000 mg a day can significantly improve blood pressure and heart health. The FDA ties higher-sodium diets to a greater risk of developing hypertension.
With kidney disease, a patient education page from UM Health says not to choose foods with more than 400 mg of sodium per serving. Even a small restaurant bowl clears that roughly three times over.
Heart failure is more individual. The sodium target comes from the care team, not from a general chart.
When the limit does not apply
The AHA’s ideal limit isn’t written for everybody.
The association says the guideline may not apply to people who lose large amounts of sodium in sweat, such as competitive athletes and workers under heat stress. A salty bowl after hard training is a different question from a salty bowl at a desk.
The limit also shifts with who you ask. WHO recommends less than 2,000 mg of sodium a day for adults, which makes a bowl of pho look heavier than it does against the US Daily Value.
How often you eat it decides the rest. One bowl in a day of low-sodium meals fits. A bowl every lunch turns pho into a main sodium source.
How to lower the sodium in pho

At a restaurant you can leave broth behind and go easy on the table sauces, and that’s about the extent of it. At home you can also start from a reduced-sodium stock and measure the fish sauce.
At the restaurant

Ask for the hoisin and sriracha on the side, or skip them. The AHA recommends asking for sauces on the side, and the basil on the plate, a squeeze of lime and some sliced chili add flavor without the sodium.
Portion matters too. The AHA suggests sharing or taking half home when portions are large, so a smaller bowl or a half you set aside both work.
Leave at least half the broth, since the noodle-soup tests above point at the soup and not the solids. And eat the noodles promptly so they absorb less of it.
None of this turns a restaurant bowl into a low-sodium meal. It trims it.
At home
Giant Food Stores’ store-brand beef broth lists 830 mg of sodium per cup in the regular version and 420 mg in the reduced-sodium one.
Three cups, which is the broth for a large bowl, come to 2,490 mg against 1,260 mg. That swap alone saves 1,230 mg.
Measure fish sauce by the teaspoon, and don’t count on a reduced-sodium label to do the work. In a small 2025 University of Debrecen student thesis on seven Thai fish sauces, the two low-sodium samples averaged only 21% less sodium than the five traditional ones.
El Camino Health’s Chinese Health Initiative lists ginger, garlic, green onion, lemongrass, star anise, five spice powder and basil as substitutes for high-sodium sauces. Most of those already belong in a pho pot.
A stock with no salt at all tastes flat, which is why some cooks blend a no-sodium stock with a lower-sodium one.
Common questions about pho and sodium
Is pho lower in sodium than ramen?

Not per gram. USDA FoodData Central lists pho with meat at 365 mg per 100 g and ramen noodle soup prepared with water at 282 mg.
Per bowl the two overlap, since Hong Kong’s Centre for Food Safety measured 2,000 to 4,000 mg in restaurant ramen (2020).
How healthy is pho apart from the sodium?
Mostly healthy. USDA FoodData Central lists pho with meat at 77 kcal and 5.8 g of protein per 100 g, so a 500 g bowl lands near 385 kcal and 29 g of protein.
The calorie count of a typical bowl is moderate. Fiber is the other weak spot at 0.4 g per 100 g, which is why extra vegetables help.
What does low sodium mean on a food label?
The FDA counts 140 mg or less per serving as low sodium, and 35 mg or less as very low.
Reduced sodium only means at least 25% less than the regular product, so a reduced-sodium stock isn’t automatically a low-sodium one.
Can kids eat pho?
Yes, in a smaller portion. The FDA notes that recommended sodium limits are lower for children under 14, so a full restaurant bowl takes a bigger share of a child’s day than of an adult’s.
Splitting a bowl and keeping the rest of the day’s meals low in sodium covers most of it.
Fitting a Bowl of Pho into a Low-Sodium Day

A bowl fits inside a 2,300 mg day only if the rest of the day stays near 475 mg after a 500 g bowl, or near 1,020 mg after a 350 g bowl.
The AHA’s 1,500 mg ideal is stricter. Above roughly 410 g, a single bowl at USDA’s 365 mg per 100 g passes it by itself.
The fixes aren’t equally solid. Table sauces come first because the amounts are known, and bowl size comes next because it saves a fixed amount per gram. The leftover broth saving is an extrapolation, so lean on it last.
For the mechanics of working through a bowl, see how to eat pho.
These numbers rest on the FDA’s 2,300 mg Daily Value and the AHA’s 1,500 mg ideal as verified in October 2026. A revision to either threshold changes every budget above.
