Benefits of sea salt, properties and uses

Health 16 October 2025

For some time now, taking care of oneself through nutrition has become a priority goal for society. Yet a fundamental ingredient such as salt is often overlooked. However, there are many other interesting facts about it that remain little known to the general public. Let’s review them.

Origins and properties of salt

First of all, it should be borne in mind that salt can be of marine or geological origin. A distinction can thus be made between sea salt, which comes from the evaporation of seawater in salt pans, and common salt, which is extracted from underground deposits. Both are composed mainly of sodium chloride.

On the one hand, it should be noted that salt from the sea is the same as sea salt. This type of salt contains more trace elements and is also less processed, since it is obtained through natural drying. On the other hand, among the properties of this unrefined salt, its more intense flavour stands out, which is why one of the uses of sea salt is adding the finishing touch to gourmet dishes.

By contrast, common salt, which may come from the sea or from a mine, is the result of a refining process designed to remove impurities. In fact, it is usually artificially iodised. For all these reasons, this type of salt is reserved for cooking and baking, as it dissolves quickly.

Regarding sea salt and its uses, its culinary role stands out both in enhancing flavours and in acting as a preservative, as it inhibits bacterial growth in meats, preserves and pickles. Likewise, salt is useful for controlling fermentation in baking and dairy products, as well as serving as a mineral supplement in livestock farming. Another property of unrefined sea salt that is regularly put to use is de-icing roads.

Meanwhile, there is also a type of industrial salt that can be used in the production of caustic soda (sodium hydroxide) and chlorine by electrolysis, as well as in the manufacture of detergents, soaps and other chemicals, water softening in water treatment, and the removal of impurities in the textile and metallurgical industries.

10 benefits of sea salt

Did you know that sea salt not only adds flavour to your dishes, but that its quality also influences your health? Here we review the main characteristics of sea salt and benefits you may not have known about.

Strengthens the immune system

This is one of the main benefits of sea salt. The minerals present in it help strengthen the immune system, which prevents the development of infections and illnesses.

Promotes digestive health

Sea salt is good for digestion. In fact, the chloride it contains is necessary for the production of hydrochloric acid in the stomach, which is responsible for breaking down food and absorbing its nutrients efficiently.

Maintains an optimal level of hydration

It is worth noting that another of the most prominent benefits of sea salt is that it helps regulate the amount of water inside our body, which helps prevent dehydration and ensures that our body functions optimally.

Ensures the proper functioning of the nervous system

The sodium contained in salt is a crucial electrolyte that enables the proper transmission of nerve impulses. It is also essential for muscle contraction and relaxation, thus preventing issues such as cramps.

May help regulate blood pressure

Contrary to popular belief, when consumed in moderation, salt can help control blood pressure. The key lies in electrolyte balance, where the mineral richness of sea salt makes all the difference.

Provides essential minerals

Another of the 10 benefits of salt worth highlighting is that it is not composed solely of sodium chloride, but is a rich salt with minerals that naturally provides essential trace elements such as magnesium, calcium and potassium, which are largely lost during the refining process, as happens with common salt.

Effective for oral hygiene and skin cleansing

One of the main benefits of salt is that, diluted in water, it acts as a natural antiseptic that relieves irritations and mouth ulcers. Furthermore, when applied topically, its trace elements contribute to deep skin cleansing and the elimination of toxins.

Supports bone health

An adequate intake of sodium helps keep both bones and teeth in optimal condition.

Relieves stress

Among the benefits of sea salt, it is worth mentioning its ability to relax muscle tension and relieve stress when taking a sea salt bath. Its minerals, upon coming into contact with the skin, help release toxins.

Improves sleep quality

Minerals such as magnesium, which is naturally present in our sea salt, help regulate melatonin and serotonin, thereby promoting a sense of well-being that also improves sleep quality.

However, beyond salt and its benefits, there are contraindications that must be taken into account, such as excessive consumption—a problem common to all foods. For that very reason, the World Health Organization (WHO) recommends consuming less than 5 grams of salt per day.

In any case, as you can see, the advantages offered by salt consumption are numerous and significant, making it an indispensable ingredient for a healthy diet.

That is why at Dama Blanca we believe that salt should not overpower the flavour of food, but rather enhance it while providing the nutrients your body needs. Furthermore, our sea salt is produced in an artisanal manner, from the screening process through to packaging, guaranteeing a natural salt that retains its minerals and is therefore healthy.
