Questions about low sodium salt
What is a low sodium salt?
A salt with 140 mg or less of sodium in 1/4 tsp (1.25 mL), the amount federal labeling rules use to compare salts and salt substitutes, and in 50 g: the rules test a food with a small serving on 50 g as well. That is the line for the words “low sodium” on a package. “Very low sodium” is 35 mg or less, tested the same way, and “sodium free” is under 5 mg.
Is there a sodium free or no sodium salt?
Yes. 5 of the salts and salt substitutes here are sodium free: under 5 mg in 1/4 tsp (1.25 mL) and in the package's own serving. “No sodium” on a package means the same.
Is there a reduced sodium salt?
2 of the salts and salt substitutes here carry “reduced sodium”, “less sodium” or “lower sodium” in the name. On a package those words mean at least 25 percent less sodium than the regular food it is compared with, so a reduced sodium salt can still be above the low sodium line.
Does Morton make a low sodium salt?
Yes.
Morton Salt Substitute has 0 mg per 1/4 tsp (1.4 g), 0 mg in 1/4 tsp.
Does NoSalt make a low sodium salt?
Yes, on an older package.
NoSalt Original Sodium-free Salt Alternative has 0 mg per 1/4 tsp (1.3 g), 0 mg in 1/4 tsp (an older package).
Does Nu-Salt make a low sodium salt?
Yes.
Nu-Salt Salt Substitute has 0 mg per 1/6 tsp (1 g), 0 mg in 1/4 tsp.
Does LoSalt make a low sodium salt?
No LoSalt salt here is at the low sodium level. Its lowest:
LoSalt Iodized Reduced Sodium Salt Alternative has 170 mg per 1/4 tsp (1.3 g), 170 mg in 1/4 tsp (an older package).
Does Diamond Crystal make a low sodium salt?
No Diamond Crystal salt here is at the low sodium level. Its lowest:
Diamond Crystal Kosher Salt has 280 mg per 1/4 tsp (0.7 g), 280 mg in 1/4 tsp.
What are the nutrition facts of the lowest sodium salt?

How to read the numbers
Sodium in one serving, from the package's Nutrition Facts. The serving is next to it.
% Daily Value is that serving's share of 2,300 mg, the Daily Value for sodium on US packages.
In 1/4 tsp (1.25 mL): every package on the same amount, so a small serving and a large one line up.
Level: a green tag means the package meets a federal level in 1/4 tsp and in 50 g: low sodium (140 mg or less), very low sodium (35 mg or less) or sodium free (under 5 mg). A label that gives its serving only in mL does not say what 50 g holds, so that package gets no tag.
Nutrition opens the rest of one serving's Nutrition Facts and the ingredient list. More nutrition puts those numbers in the list, to order by any of them.
Filters narrow the list by store, brand, the words on the label and ingredients. An ingredient filter also leaves out products that give no ingredient list.
2024 or newer: the list opens with packages from 2024 or later. Untick the box to add older ones; some may have changed or left the shelf.
These are package numbers, not advice. How much sodium is right for you is for your doctor or dietitian to say.
