Sea Salt Safety: What You Should Know Before You Sprinkle It on Everything 🧂
Sea salt has become one of the biggest “health halo” products in the wellness world. Many people assume that because it is natural, gray, pink, coarse, or unrefined, it must automatically be healthier than standard salt.
But here is the truth:
Not all sea salts are created equal.
Source, harvesting method, refinement, and contamination levels matter more than marketing.
Recently, a discussion from Paul Saladino and independent testing from ABNRF sparked a bigger conversation around salt quality, heavy metals, and how to choose wisely.
Why Salt Still Matters for Health
Salt is not the enemy many people were taught to believe.
Sodium plays a critical role in:
Hydration balance
Nerve signaling
Muscle contraction
Energy production
Blood pressure regulation
Adrenal and stress resilience
Athletic performance
Many active people, low-carb eaters, sauna users, and those under chronic stress often need more electrolytes, not less.
The issue is usually quality and balance, not simply salt itself.
The Sea Salt Problem: Potential Contaminants
Sea salt is made from evaporated seawater. That sounds simple and natural, but modern oceans are exposed to pollution, industrial runoff, plastics, and environmental contaminants.
Depending on where the salt is harvested, some brands may contain measurable amounts of:
Lead
Arsenic
Aluminum
Cadmium
Microplastics
A 2025 independent ABNRF study tested seven popular salts for heavy metals and microplastics. Their reported findings showed some products had measurable contaminants, while others had no detectable heavy metals.
Brands That Tested Clean in That Review
According to the ABNRF published results, these salts had no detectable heavy metals in their testing:
Morton Iodized Salt (reported clean in some referenced summaries)
My Preferred Recommendations
If someone asks me for practical everyday choices, I would lean toward:
Diamond Crystal
Excellent for cooking, dissolves well, light texture, easy to use, commonly trusted in kitchens.
Jacobsen Salt Co.
Beautiful finishing salt, clean taste, premium texture, excellent for higher-end meals.
Ava Jane’s Colima Sea Salt
Specialty use and finishing meals
What About Celtic Salt or Trendy Mineral Salts?
Many people use gray Celtic-style salts because they believe the extra minerals make them healthier.
Reality check:
Those trace minerals are usually present in tiny amounts that will not meaningfully impact magnesium, potassium, or nutrient status.
You would be better off getting minerals from:
Red meat
Fruit
Dairy
Potatoes
Mineral water
Quality supplements if needed
The concern is that some unrefined salts may also carry more environmental contaminants depending on source and processing.
Should You Fear Salt?
No.
Salt is essential. Over-restricting sodium can create issues like:
Fatigue
Headaches
Low energy
Exercise intolerance
Dizziness
Cravings
Poor performance
The goal is not “avoid salt.”
The goal is:
Use quality salt intelligently.
My Practical Salt Strategy
Everyday Cooking:
Finishing Meals / Premium Taste:
Hydration / Electrolytes:
Pair salt with:
Potassium-rich foods
Magnesium
Water
Adequate protein
Final Thoughts
Salt should support your health—not become another hidden source of unnecessary toxic burden.
If you are using salt daily (and most of us are), quality matters.
You do not need the trendiest salt on Instagram. You need one that is:
Clean
Reliable
Tastes great
Fits your lifestyle
Sometimes the smartest wellness move is also the simplest one.
My picks: Diamond Crystal + Jacobsen.
