Non-Iodised Sea Salt: Pure, Natural, and Unrefined

Non-iodised sea salt is a type of salt that is harvested from evaporated seawater and does not contain added iodine, a nutrient commonly included in processed table salt. This form of sea salt is valued for its purity, natural mineral content, and versatility in culinary, cosmetic, and wellness applications. For those who prefer a more natural lifestyle or follow specific dietary needs, non-iodised sea salt offers a simple, unprocessed alternative.

What Is Non-Iodised Sea Salt?

Unlike regular table salt, which is heavily refined and often contains additives like iodine and anti-caking agents, non-iodised sea salt is minimally processed. It is made by allowing seawater to evaporate in large, open salt pans under the sun. The salt crystals that remain are then collected, dried, and packaged without the addition of iodine or any chemical treatment.

Non-iodised sea salt retains many trace minerals that are naturally found in seawater, such as magnesium, calcium, potassium, and iron. These minerals contribute to the salt’s slightly off-white color and more complex, less sharp flavor compared to pure sodium chloride.

Why Choose Non-Iodised Sea Salt?

1. Pure and Natural – Non-iodised sea salt is as close to nature as it gets. It doesn’t undergo industrial refining, and there are no synthetic additives. This makes it a favorite among people who seek clean-label, whole food ingredients.

2. Ideal for Fermentation and Pickling – In fermentation processes like making sauerkraut, kimchi, or pickles, iodine can interfere with the growth of beneficial bacteria. Non-iodised sea salt is therefore recommended for these recipes to ensure proper fermentation and flavor development.

3. Preferred in Certain Diets – Individuals on natural, paleo, or low-iodine diets may choose non-iodised sea salt to avoid excess iodine intake. Some people with thyroid conditions, particularly those preparing for medical treatments, are advised to limit iodine temporarily, making non-iodised salt an essential pantry item.

4. Better Texture and Flavor – Many chefs prefer non-iodised sea salt for its slightly briny, more rounded flavor. Its larger, coarser crystals also add texture to dishes, making it ideal for finishing salads, roasted vegetables, and grilled meats.

5. Multi-Purpose Use – Beyond cooking, non-iodised sea salt is commonly used in DIY skincare, salt scrubs, oral rinses, and natural cleaning solutions. Because it doesn’t contain additives, it’s gentle and suitable for various wellness applications.

Iodine Consideration

While non-iodised sea salt has many benefits, it’s important to ensure you're getting enough iodine through other sources if you're not using iodised salt. Iodine is essential for thyroid function and hormone production. Foods like dairy, eggs, seaweed, fish, and fortified products can help maintain healthy iodine levels.

Conclusion

Non-iodised sea salt is a natural, additive-free alternative to standard table salt. With its clean composition, rich mineral profile, and versatility, it serves as a valuable ingredient in both cooking and natural living. Whether you're an avid home cook, a fermentation enthusiast, or someone seeking a cleaner diet, non-iodised sea salt is a simple switch that aligns beautifully with a wholesome, mindful lifestyle.
