The Surprising Health Benefits of Celtic Sea Salts

Celtic sea salt, a gem of the culinary world, steeped in history and bursting with surprising health benefits has gained considerable attention. So what is it about the Celtic sea salts that’s causing it to take the world by storm?

When stacked against other salts, like Himalayan pink salt or standard table salt, Celtic sea salt holds its own. Celtic sea salt, is harvested from the pristine waters of the Celtic Sea near Brittany, France. This unrefined sea salt, traditionally hand-harvested, retains its natural moisture and a wealth of minerals. Its characteristic grey hue, a testament to its mineral content and clay from salt flats, sets it apart from the stark white of regular salt.

Health benefits of Celtic sea salt

  • In its natural form, Celtic sea salt contains amounts of magnesium, potassium, calcium, and other electrolytes that are similar to those found in the human body. This allows the salt to effectively help the body balance fluids and retain hydration .
  • The salt’s digestive and electrolyte benefits may also help endurance athletes remain properly hydrated during training and competition.
  • Early research findings suggest that switching to a high-quality, unrefined salt may benefit cardiovascular health. While excess sodium from highly refined salts may raise blood pressure in salt-sensitive individuals, unrefined salts like Celtic sea salt do not appear to raise blood pressure. More research is still needed to validate these initial studies. 

How much Celtic sea salt to take daily?

The American Heart Association recommends limiting sodium intake to no more than 2,300 mg per day, with an ideal limit of no more than 1,500 mg for most adults.

Since Celtic sea salt is about 85-90% sodium chloride, consuming less than 1 teaspoon (around 2,000 mg of sodium) per day would keep most individuals within the recommended limits.

When using Celtic sea salt, moderation is still key. Consuming extremely high amounts of even the healthiest salt may lead to excess sodium intake. But when used judiciously to add flavor and nutrients, Celtic sea salt offers health perks not found in regular refined table salt. So reach for this mineral-rich seasoning as a tasty way to add some nutritional benefits to your diet
