Sea Salt vs Himalayan Salt — Which Is Better?

The Short Answer

If you are choosing based on flavor and texture, it's a toss-up: Himalayan is milder and earthier, while sea salt is brinier and punchier.

If you are choosing for health and purity, the answer is complicated. Himalayan salt is not the 'pure' ancient superfood it claims to be. Recent independent testing has found it can contain higher loads of microplastics than sea salt (due to atmospheric pollution during processing) and consistent levels of heavy metals like aluminum and lead.

The winner is specific, not generic. High-quality sea salts from protected waters—specifically Jacobsen (Oregon) and Maldon—currently test cleaner for heavy metals than both Himalayan pink salt and the popular Celtic Sea Salt.

Why This Matters

All salt is sea salt. Himalayan salt is just sea salt from a Jurassic-era ocean that dried up millions of years ago. The marketing implies that because it's "ancient," it's free of modern pollution.

Ancient doesn't mean clean. While the deposit itself is old, the mining, crushing, and packaging processes expose the salt to modern air and machinery. Microplastics In Sea Salt studies have surprisingly found that some rock salts contain more plastic particles than salt taken straight from the ocean today.

Minerals are a myth. You often hear that pink salt has "84 trace minerals." This is true, but misleading. They exist in such microscopic quantities that they have zero impact on your health. You would need to eat a lethal amount of salt to get the same minerals found in a handful of spinach.

What's Actually In Your Salt

Most "natural" salts are 98% Sodium Chloride. The remaining 2% is where the difference lies—impurities that can be good (minerals) or bad (metals/plastic).

• Sodium Chloride — The main event. Both sea and Himalayan salt have slightly less sodium by volume than table salt simply because the crystals are larger and don't pack as tightly.
• Microplastics — Tiny plastic fragments found in 90% of all salt brands. They come from ocean pollution or packaging/processing dust. Microplastics In Sea Salt
• Heavy Metals — Lead, arsenic, and aluminum are naturally occurring in the earth's crust. Mined salts (Himalayan, Redmond) and clay-based salts (Celtic) often have higher levels of these than filtered water salts. Heavy Metals In Spices
• Iron Oxide — This is rust. It's what gives Himalayan salt its pink color. It is not a bioavailable source of iron for your body.

What to Look For

Green Flags:

• Sourced from North America/Europe: Testing shows stricter standards and cleaner waters (e.g., Oregon, Iceland, UK) often yield cleaner salt.
• "Kosher" Style Flakes: The process to make flaky salt often involves filtration that removes heavy sediments where metals lurk.
• Third-Party Purity Testing: Brands that publish their own heavy metal reports (COAs).

Red Flags:

• "Grey" Wet Salts: The grey color often comes from clay lining the salt pans. This clay is frequently where lead and arsenic accumulate.
• Generic "Himalayan" Labels: This is a commodity product with zero quality control. It could be from any mine in Pakistan with varying safety standards.
• "Source of Minerals" Claims: A brand selling you salt as a vitamin supplement is red-flag marketing.

The Best Options

We analyzed recent independent lab tests (including data from 2024-2025) to rank these popular salts.

Note: Jacobsen also sells an Italian sea salt. Recent tests flagged the Italian version for lead. Stick to their Oregon-sourced jars.

The Bottom Line

1. Stop buying salt for minerals. Eat vegetables for magnesium and potassium. Use salt for flavor.

2. Switch to Jacobsen (Oregon) or Maldon. These offer the best balance of low heavy metals and great texture.

3. Ditch the Grey Salt. The "wet" grey salts are trendy, but the clay content brings unnecessary lead exposure.

4. Use Iodized Salt occasionally. Neither sea nor Himalayan salt has enough iodine. If you don't eat seaweed or seafood, keep a small shaker of iodized salt (like Morton's) for occasional use to support thyroid health. Do You Need Iodized Salt

FAQ

Is Himalayan salt better for blood pressure?

No. It contains roughly the same amount of sodium by weight as any other salt. Because the crystals are larger, you might use less by volume, but chemically it creates the same spike in blood pressure if overconsumed.

Does boiling water remove microplastics from salt?

No. Microplastics are solids; they do not evaporate or dissolve. If they are in your salt, they end up in your food. The only way to remove them is through physical filtration before the salt crystallizes, which is why filtered flake salts often test cleaner.

Why is Celtic Sea Salt considered "dirty"?

Recent independent tests have shown Celtic Sea Salt containing lead levels around 500 ppb. While the company claims this is "naturally occurring," it is significantly higher than brands like Jacobsen or Diamond Crystal, which test at 0 ppb (non-detect). For a product used daily, lower is better.
