Salt is one of the most fundamental ingredients in cooking and nutrition. It enhances flavour, preserves food, and plays a critical role in hydration and nerve function. With so many varieties available, the debate between sea salt and table salt often comes down to health benefits, taste, and processing methods. So, what’s the real difference?
In this guide, we’ll explore how sea salt and table salt compare in terms of source, processing, mineral content, and everyday use. Whether you’re cooking at home or making mindful dietary choices, understanding these differences can help you choose the salt that best suits your needs.

How Are Sea Salt and Table Salt Sourced and Processed?
The key difference begins at the source. Sea salt is harvested through the natural evaporation of seawater, typically using traditional methods that preserve its trace minerals. It’s often minimally processed, which helps it retain its natural grey or off-white colour and moist texture. Celtic Sea Salt, for example, is hand-raked from clay salt beds in coastal France, keeping its mineral profile intact.
Table salt, on the other hand, is typically mined from underground salt deposits and then heavily refined. This process removes most naturally occurring minerals and often includes bleaching agents and anti-caking additives to ensure the salt flows freely. While it provides a consistent texture and is widely available, the high level of processing means table salt lacks the trace minerals found in natural alternatives.
For those seeking a less processed, mineral-rich option, Celtic Sea Salt offers a natural choice sourced using sustainable, traditional techniques.
What Minerals and Additives Do They Contain?
Sea salt contains naturally occurring trace minerals such as magnesium, potassium, calcium, and zinc. These contribute not only to its slightly complex flavour but also offer added nutritional value. The specific mineral content varies by origin and harvesting method, but overall, sea salt retains more of its natural properties.
Table salt, by contrast, is stripped of these minerals during refinement. To compensate, manufacturers often add iodine — an essential nutrient that supports thyroid function — as well as anti-caking agents like calcium silicate. These additives may not be a concern for everyone, but individuals looking to minimise chemical additives may prefer sea salt.
It’s important to note that sea salt does not naturally contain significant levels of iodine. Those with iodine deficiencies may still require dietary supplementation or a balance of iodised salt when necessary.
Does Sea Salt Have Less Sodium Than Table Salt?
This is one of the most common questions — and one that’s often misunderstood. By weight, sea salt and table salt contain roughly the same amount of sodium. However, because sea salt typically has larger, irregular crystals, a teaspoon of sea salt delivers less sodium than a teaspoon of finely ground table salt.
This means you may use less sodium overall when seasoning with coarse sea salt. Additionally, the stronger, more robust flavour of sea salt often means less is needed to achieve the desired taste.
That said, sodium intake should still be monitored closely, especially for those with high blood pressure or cardiovascular concerns. Regardless of the type, moderation is key.
How Do Sea Salt and Table Salt Compare in the Kitchen?
From a culinary perspective, both salts serve different purposes depending on the dish. Sea salt is often favoured by chefs and home cooks for its clean, briny flavour and crunchy texture. It works well as a finishing salt on grilled vegetables, roasted meats, or salads. Its coarse crystals provide a pleasing contrast and visual appeal.
Table salt is more uniform and dissolves easily, making it ideal for baking, where precision and consistency are critical. Its fine granules ensure even distribution throughout batters and doughs.
Moisture also plays a role. Sea salt may clump slightly in humid environments due to its natural moisture content, while table salt remains free-flowing due to anti-caking additives.
If you’re looking for enhanced flavours, explore options like Smoked Himalayan Salt, which adds a bold, savoury element to everything from grilled meats to cocktails.
Is Sea Salt Better Than Table Salt for Your Health?
While both sea salt and table salt contain sodium and serve the same basic function, sea salt is generally considered the more natural option. Its minimal processing means it retains trace minerals and remains free from additives commonly found in table salt.
That said, iodised table salt plays a critical role in public health by helping prevent iodine deficiency — a common issue in areas where seafood or dairy intake is low. For most people, a balanced intake of different salt types — including sea salt for its flavour and table salt when iodine is required — offers a practical solution.
Ultimately, the better choice depends on your health needs, cooking preferences, and commitment to natural ingredients.
