8 US Salt Brands You Must Avoid

Headline finding

Independent, EPA‑certified lab testing and peer‑reviewed studies cited in the video found widespread contamination in U.S. salt products: 96% of tested salts had detectable lead and 100% had arsenic. Sea salts and unrefined “premium” salts (especially Himalayan pink) consistently test higher for heavy metals and for microplastics than refined table salts.

Overall recommendation / verdict

• Avoid Himalayan pink salts (both brand-name and generic) and sea salts from opaque supply chains unless the brand publishes recent independent third‑party lab results for heavy metals and microplastics.
• For lowest risk of heavy‑metal contamination, choose refined salts (basic iodized table salt or certain kosher salts) that do not use aluminum‑based anti‑caking agents — or select brands that publish third‑party test data.
• Be skeptical of premium pricing and “natural/mineral” marketing. Trace minerals in unrefined salts are nutritionally insignificant at safe serving sizes.

Summary of the eight brands (ranked)

1) Generic Himalayan Pink Salt (category) - Features: Multiple brands/labels sourced from the same Pakistan mine (Khewra/“Cura”); pink color from iron oxide/trace minerals. - Cons/risks: Category consistently shows the highest levels of lead and arsenic. Fragmented supply chain, many repackagers, frequent lack of independent testing. No U.S. federal maximum lead limit for salt; FDA does not require heavy‑metal or microplastic testing/disclosure for salt. - Verdict: Biggest red flag — avoid generic/premium Himalayan pink salts unless independent lab data prove otherwise.

2) Diamond Crystal Kosher Salt - Features: Kosher salt with hollow pyramid flakes favored by chefs; consistent volume/weight ratio used in recipes. - Pros: Among the cleanest salts in cited tests (ABN RF and Mamovation testing reported no detectable heavy metals/microplastics or categorized it best). - Cons/risks: Owned by Cargill (corporate concentration) and subject to periodic supply shortages. - Verdict: Good choice for low contamination and culinary use, but be aware of availability and market concentration.

3) 365 by Whole Foods Sea Salt (Amazon/Whole Foods) - Features: Positioned as higher quality and sold at a premium. - Cons/risks: Sea salt contamination originates from the ocean (microplastics and polymers like polyethylene, polypropylene, PET). No public independent heavy‑metal or microplastic test results were found by the video’s author. - Verdict: Paying a premium without published lab verification is a concern.

4) Great Value Sea Salt (Walmart) - Features: Low‑cost, widely distributed store brand. - Cons/risks: Opaque third‑party supply chains; Walmart buys finished product and does not publicly publish independent testing. Sea salts tend to have higher microplastic counts (studies report 0 to >1,600 particles/kg). - Verdict: Budget sea salt from opaque supply chains equals unknown heavy‑metal testing and likely microplastic contamination.

5) Kroger Private Selection Himalayan Pink Salt - Features: Premium store‑brand Himalayan salt sold at scale. - Cons/risks: Same Himalayan category contamination profile as other pink salts (lead/arsenic/cadmium). Wide distribution without clear disclosure of testing or supply‑chain verification. - Verdict: Premium positioning but no evidence of better safety or testing.

6) McCormick Sea Salt - Features: Sea salt sold under a major spice/seasoning brand. - Cons/risks: McCormick faced a 2022 class action over heavy metals in spices; the company does not publish independent heavy‑metal or microplastic testing for its salt products. Sea salt is vulnerable to ocean‑borne contaminants. - Verdict: Brand recognition may create false trust; lack of published testing is a concern.

7) Kirkland Signature Himalayan Pink Salt (Costco) - Features: Large‑format grinder, marketed as “natural” and mineral‑rich. - Cons/risks: Himalayan pink salts consistently show lead, arsenic, cadmium in independent testing. Mamovation/EPA‑lab results cited: all Himalayan samples contained arsenic, 96% contained lead, 70% contained cadmium; some samples measured very high lead (example up to 553 ppb). The “84 minerals” health claim is nutritionally meaningless at safe salt intake levels. - Verdict: Looks premium but carries category contamination risks.

8) Morton Table Salt - Features: Highly refined sodium chloride, widely recognized brand. - Pros: Tests among the lower‑contamination salts for heavy metals in cited independent testing. - Cons/risks: Contains anti‑caking agents — sodium ferrocyanide (yellow prussiate of soda) and in some products calcium silicate (which can introduce trace aluminum). Sodium ferrocyanide contains cyanide in bound form; FDA and EFSA consider it safe at current use levels, but some scientists debate possible cyanide liberation in the stomach for high consumers or vulnerable people. - Verdict: Cleaner for heavy metals but additives raise separate safety questions for some consumers.

(Note: ranking follows the video’s presentation, with Himalayan pink salts treated as the highest‑risk category.)

Key numbers and studies cited

• Overall: 96% of tested salts had detectable lead; 100% had arsenic (per EPA‑certified lab testing cited).
• Himalayan salts (Mamovation/EPA‑lab results): 100% arsenic, 96% lead, 70% cadmium in samples.
• Example measurement: up to 553 ppb lead in some Himalayan samples (compared to much lower proposed action levels for baby foods).
• Aluminum detected in 78% of salt products (study cited in the video).
• Microplastics: peer‑reviewed study (Environmental Science & Technology) found microplastics in ~90% of salt brands tested worldwide; sea salts showed the highest contamination (0 to >1,600 particles/kg reported).

Regulatory and scientific context

• FDA and EFSA say sodium ferrocyanide is safe at current use levels, but debate persists about cyanide release in the stomach for vulnerable groups.
• There is no U.S. federal standard requiring heavy‑metal testing or microplastic disclosure for table/sea salts; there is no federal maximum lead content for salt.
• Health concerns: lead accumulates in bone; arsenic is a WHO Group 1 carcinogen; cadmium has a long biological half‑life (10–30 years).

Practical takeaways and recommendations

• Prefer refined salts (e.g., basic iodized table salt or Diamond Crystal kosher salt) that test cleaner for heavy metals. Avoid salts with aluminum‑based anti‑caking agents to minimize aluminum intake.
• If using sea salt or Himalayan salt, only buy from brands that publish recent third‑party lab tests for heavy metals and microplastics.
• Don’t assume expensive or “natural/mineral‑rich” labeling equals safety or nutritional benefit; trace minerals in unrefined salts are not meaningful at safe intake levels.
• Be particularly cautious for children, pregnant women, and people managing cumulative exposure to heavy metals. Reduce overall salt consumption to minimize risk.

If you want to act on this information

• Check salt labels and brand websites for third‑party lab reports (heavy metals and microplastics).
• Prefer refined iodized or tested kosher salts without aluminum‑based anti‑caking agents.
• Reduce overall salt consumption, especially for children, pregnant people, and those concerned about cumulative heavy‑metal exposure.
