Celery Seed vs. Celery Salt: Same Seed, Very Different Sodium

Celery salt is celery seed, ground and mixed with salt. McCormick’s lists exactly two ingredients, salt and celery seed.¹ The flavor is the same seed; the difference is sodium. By McCormick’s label a teaspoon of its celery salt carries about 1,080 mg of sodium, while a teaspoon of celery seed carries about 3 mg by USDA’s figures.¹² So choose celery seed when you want celery flavor you can control, and celery salt when you want salt and celery in one shake.

Both come from celery, Apium graveolens, a biennial of the parsley family (Apiaceae).³

Side by side

Both sodium figures are computed: the seed figure from USDA’s per-100 g value, the salt figure from one brand’s label. Other celery salts may differ.

The differences that change the dish

Sodium. The FDA says 2,300 mg of sodium is about one teaspoon of table salt.¹¹ By that yardstick, a teaspoon of McCormick’s celery salt carries a little under half the sodium of a teaspoon of table salt.¹¹¹ Two teaspoons carry about 2,160 mg, close to the FDA’s Daily Value of less than 2,300 mg,¹¹¹ and above the WHO’s recommendation that adults stay below 2,000 mg a day.¹² The 1/4 teaspoon serving on McCormick’s label, 270 mg, works out to about 12 percent of that Daily Value, by our arithmetic.

Celery intensity. Because celery salt is seed plus salt, a spoonful of it holds less seed than a spoonful of ground seed. How much less depends on the blend, and no source we found publishes a commercial ratio. A Couple Cooks’ own homemade version uses 1 1/2 parts celery seed to 1 part kosher salt, and the same page says purchased blends run between 1:1 and 2:1, without saying which ingredient is the larger part.⁷ In practice, if you want more celery flavor from celery salt, you also get more salt.

Texture. Whole seed adds visible flecks and a little crunch; celery salt disperses like salt. McCormick says celery seed’s pungent, somewhat bitter flavor “goes a long way” and suggests starting with a pinch.¹³

What’s in the seed

USDA’s analysis of celery seed, per 100 g, lists 1,770 mg of calcium, 44.9 mg of iron and 6.93 mg of zinc, with 3.52 g of linoleic acid.² A teaspoon is only 2 g, so it supplies about 35 mg of calcium (about 3 percent of the FDA’s 1,300 mg Daily Value) and about 0.9 mg of iron (about 5 percent of 18 mg), by our arithmetic.²¹⁴ Celery salt supplies less of each per spoon, since part of every spoonful is salt.

A 2019 review of the Apium genus reports that the fatty acids in celery seed oil are mostly petroselinic acid (64.3%), with linoleic acid at 18%, and names coumarins and the furanocoumarin bergapten among the main constituents of the seed’s essential oil.⁵ The flavonoid figures in the same review, luteolin among them, are for the leaves; it gives none for the seed.⁵

Health claims. A 2025 meta-analysis of 10 randomized trials with 511 adults found that celery preparations lowered blood pressure, fasting blood sugar and triglycerides, but had no effect on total, LDL or HDL cholesterol.¹⁵ The trials used several forms of celery, not only seed, and the authors flag small samples and substantial differences between studies.¹⁵ We found no regulator or systematic review supporting claims that celery seed reduces inflammation or protects the liver. None of this applies to celery salt, where the sodium is the number that matters. This page makes no claim that either treats or prevents any condition.

Can one stand in for the other?

Yes, in either direction, as long as you deal with the salt. Our substitute pages set out the treatments; here they are in brief.

• Celery salt for celery seed. The Spice House calls celery salt a great substitute for celery seed and says to reduce the salt elsewhere in the recipe.¹⁶ Salt (Computed): cut about 1/2 teaspoon of table salt for each teaspoon of celery salt you add, from McCormick’s label and the FDA’s teaspoon of salt.¹¹¹ Celery (Method): no source gives the seed content of commercial celery salt, so start with an equal amount and taste. See celery seed substitutes.
• Celery seed for celery salt. Salt (Computed): about 1/2 teaspoon of table salt per teaspoon of celery salt replaced.¹¹¹ Celery (Method): start with 1/4 teaspoon of ground celery seed per teaspoon of celery salt, taste, and add more. To make a jar instead, A Couple Cooks grinds 1 1/2 tablespoons of celery seed with 1 tablespoon of kosher salt (Attributed).⁷ See celery salt substitutes.
• For a lower-sodium Bloody Mary. The International Bartenders Association’s recipe calls for celery salt, Tabasco and pepper, to taste.⁸ Ground celery seed with a smaller pinch of salt gives the celery note with less sodium. That is a Method suggestion; no source gives an amount.

When to reach for each

• Celery seed for pickles, slaws, potato salad and dressings, and anywhere you want celery flavor without the stalk. The Spice House describes the seed as giving a strong celery flavor without the stalk’s stringy, fibrous texture.¹⁶ Uses beyond that are common practice.
• Celery salt where salt and celery go on together at the end: the Bloody Mary and the Chicago-style hot dog, which is finished with it.⁸⁹

What isn’t known

• No source we read publishes the salt-to-seed ratio of commercial celery salts, and the one source that gives a range does not say which way round it runs.
• The sodium figure for celery salt comes from one brand’s label.
• No published study compares the flavor strength of celery salt with celery seed.
