Redmond Real Salt contains over 60 trace minerals, though the vast majority of what you’re eating is still sodium chloride, which makes up about 98% of the salt by weight. The remaining 2% is a mix of trace minerals including calcium, potassium, magnesium, iron, manganese, zinc, and iodine, among dozens of others. These minerals give the salt its distinctive pink and reddish color and are the main reason people choose it over standard table salt.
The Major Minerals
Like any salt, sodium is the dominant mineral. A quarter-teaspoon serving of Redmond Real Salt contains roughly 530 mg of sodium, which is comparable to most other salts by volume. Chloride makes up the other half of the sodium chloride molecule, so together these two elements account for nearly all of the salt’s weight.
Beyond sodium and chloride, the minerals present in meaningful (though still small) amounts include calcium, potassium, magnesium, sulfur, and iron. The iron content is what creates the pinkish-red specks throughout the salt. Potassium and magnesium are present but in trace quantities per serving. You’d need to consume far more salt than is healthy to get a nutritionally significant dose of either mineral from Real Salt alone.
Naturally Occurring Iodine
One detail that sets Redmond Real Salt apart from many unrefined salts is its natural iodine content. Each quarter-teaspoon serving contains roughly 18 to 23 micrograms of naturally occurring iodine. For context, the recommended daily intake of iodine for adults is 150 micrograms. So a quarter teaspoon gets you about 12 to 15% of your daily iodine needs, assuming you absorb all of it.
This matters because most unrefined salts, including Himalayan pink salt, contain negligible iodine. Standard table salt is fortified with iodine specifically because deficiency was once widespread. Redmond Real Salt offers a middle ground: some natural iodine, but not enough to rely on as your sole source.
Trace Minerals in Small Amounts
The full mineral analysis published by Redmond lists over 60 elements, many of which are present at parts-per-million or parts-per-billion levels. These include zinc, manganese, copper, silicon, phosphorus, and selenium, along with less familiar elements like strontium, barium, and rubidium. Some of these are essential nutrients in tiny amounts. Others are simply naturally present in the ancient seabed deposit in central Utah where the salt is mined.
It’s worth being realistic about what “60+ trace minerals” means in practice. The amounts are extremely small. A quarter teaspoon of salt weighs about 1.5 grams, and the trace mineral fraction of that is measured in micrograms. You get far more potassium from a single banana, more magnesium from a handful of almonds, and more calcium from a glass of milk than you’d get from an entire day’s worth of Real Salt. The trace mineral profile is genuinely there, but it’s a bonus rather than a reliable nutritional source.
How It Compares to Himalayan Pink Salt
Redmond Real Salt and Himalayan pink salt have similar mineral profiles because both are ancient sea salt deposits. Both contain iron (giving them their color), both have trace amounts of calcium, potassium, and magnesium, and both are roughly 98% sodium chloride. The practical differences in mineral content between the two are minimal.
The most notable difference is iodine. Redmond Real Salt contains 18 to 23 micrograms per serving, while most Himalayan salts contain little to no measurable iodine. Both salts are unrefined and free of the anti-caking agents found in standard table salt. Choosing between them comes down to preference, price, and sourcing rather than a significant nutritional gap.
Heavy Metals and Safety
Because Redmond Real Salt is an unrefined mineral product, it also contains trace amounts of less desirable elements, including lead and arsenic. Independent lab testing has found lead levels around 290 parts per billion in Redmond Real Salt. That number is well below the European Union’s limit for lead in salt, which is 1,000 parts per billion. However, it exceeds the much stricter action levels proposed (though never adopted into law) by the Baby Food Safety Act of 2021 in the United States, which set a proposed threshold of 5 parts per billion for baby foods.
This is a genuine gray area. At normal seasoning quantities, the amount of lead you’d ingest from Real Salt is extremely small in absolute terms. Adults consuming typical amounts of salt are exposed to lead levels far below what regulatory agencies in Europe consider concerning. For young children and infants, who are more sensitive to heavy metal exposure, some parents and advocates prefer to use a more refined salt. The key point is that trace heavy metals are present in virtually all unrefined salts, not just Redmond’s product, because they come directly from mineral deposits in the earth.
What the Mineral Content Means for You
If you’re choosing Redmond Real Salt for its minerals, the honest picture is this: it does contain a broader mineral spectrum than refined table salt, and it provides a modest amount of natural iodine. But salt is something you eat in small quantities, so the nutritional contribution of its trace minerals is minor compared to what you get from whole foods. The real appeal for most people is that it’s minimally processed, has no additives, and tastes noticeably different from standard table salt, with a slightly sweeter, less sharp flavor that many cooks prefer.
For electrolyte replenishment after exercise or heavy sweating, Real Salt alone won’t deliver the potassium and magnesium your body needs. That’s why Redmond also makes a separate electrolyte product (Re-Lyte) that adds 400 to 500 mg of potassium and 50 to 60 mg of magnesium per scoop, amounts that far exceed what the salt itself provides.
