Your salt is not the problem.

Every single salt on the US shelf has lead in it, some at 800+ ppb, which sounds like a five-alarm fire. Except you eat two grams of salt a day, and the actual dose from any of them is tiny. Meanwhile, the pink-Himalayan panic is louder than ever. Here’s the real math, the two brands that test cleanest, and what to spend your money on instead.

Salts tested: 11
All contain lead: 100%
ppb range: 69–819
Peak daily dose: 1.6 µg

ICP-MS results from DetectLead's own 11-salt panel, November 2024. Peak dose assumes 2g/day.

Buy the cheapest iodized salt. Filter your water. Stop worrying.

Great Value iodized salt tested at 69 ppb, delivers 0.14 µg of lead per daily 2g serving. That’s about 6% of a child’s daily reference level. Done.

Pink Himalayan, the one Instagram told you was the pure, natural choice, tests at up to 520 ppb. Same with Celtic, Redmond, anything labeled “trace minerals.” Trace minerals is marketing for “we didn’t refine the lead out.”

Worth more than any salt choice: filter your tap water with a $30 NSF-53 certified filter. That’s the real easy win.

The recommendation

Buy Great Value iodized salt. $0.50 for 26 oz.

Great Value iodized: 69 ppb lead. 0.14 µg per daily 2-gram serving. About 6% of a child’s FDA IRL. The cleanest mainstream salt in the US grocery shelf, and it costs less than anything you would buy as a “one of the low lead ones.”

I tested it. So has Lead Safe Mama. The numbers replicate.

$0.50

Walk past the artisan aisle. Pick up the blue Walmart cylinder.

The mainstream supermarket iodized salt category is the cleanest by ICP-MS in independent testing. Pink Himalayan, Celtic, Redmond, McCormick Himalayan, “trace mineral” salts, all test materially worse than the boring cylinder, while charging 10–40× more per ounce.

Why? Mainstream iodized is industrially refined. Refining strips trace contaminants along with everything else. The premium “mineral” story is built on what they don’t refine out. The thing they don’t refine out includes the lead.

Pink Himalayan is a brand story about dirt.

Pink salt is pink because of iron oxide. “Trace minerals” means “we kept the dirt in.” The “dirt” in question includes lead, arsenic, cadmium, the exact toxic elements you’re trying to avoid in your kid’s food. The more premium-looking the pink salt, the more it costs, the more likely it’s been marketed around the trace-mineral story. Meanwhile, the generic Walmart bag next to it tests cleaner than any of them.

The three easy wins

What to actually do tonight.

Switch to Great Value iodized ($0.50 for a 26oz cylinder).

69 ppb, 0.14 µg per daily serving, 6% of a child’s IRL. It is the cleanest mainstream salt in the US market and it costs less than anything you’d buy at Whole Foods. Morton Iodized is 8× worse. McCormick Himalayan is 7.5× worse. You are not upgrading by paying more.

Stop buying anything marketed on “trace minerals,” pink color, or “natural mineral content.”

Celtic, Redmond Real Salt, McCormick Himalayan, Riega, Pink Himalayan from premium brands, all test dirtier than Walmart generic. The pink-natural-mineral positioning is a marketing story about dirt being good for you. In this specific case, the dirt is lead. Do not pay extra for it.

Put a $30 NSF-53 filter on the kitchen tap. That’s the real move.

The cleanest salt on this chart delivers 0.14 µg of lead per day. Tap water at 1 ppb x 1 liter per day delivers 1 µg. An NSF-53 certified pitcher or tap filter cuts residual lead to sub-ppb. It’s the single highest-impact thing you can do in a kitchen for under $50.

Verify certification: the box must say “NSF/ANSI 53, Lead reduction” (not just NSF 42).

Why this matters less than you think

Concentration isn’t dose. Serving size is.

The panic around salt is a classic ppb-vs-dose error. A food with 800 ppb and a 2g serving delivers less lead than a food with 20 ppb and a 240g serving. We walked through all the math on /compare, including the salt vs. tap-water comparison that makes the scale obvious.

The 2-second version: canned tomato soup, 20 ppb lead, 240g serving, delivers 4.8 µg. Morton Kosher salt, 819 ppb lead, 2g serving, delivers 1.6 µg. The “clean” food delivers 3× more lead than the “dirty” salt, because you eat 120× more of it.
