With the help of our seasoned H&B food team and in-house scientists, we’re diving into everything Celtic salt and asking what it might bring to the table
Summary

Having piled up over 36 million posts on TikTok, Celtic salt is certainly shaking up the food world. But how much more nutritious can salt really be than... salt? We asked our Head of Science Abbie Cawood and Category Manager Launa Humphreys to sprinkle us with their knowledge.
So, let’s get into the nitty-gritty of this trending ingredient.
What is Celtic salt?
Although the name might suggest it hails from the Celtic Sea, it’s actually hand-harvested from the coasts of France and Portugal. The nod to the Celts actually comes from the traditional collection methods of sun and wind evaporation.
“The seawater is collected from tidal pools and channelled into ‘oeillets’, shallow, clay-lined salt marshes, to allow the water to evaporate and salt to crystallize, maintaining its rich mineral content,” says Abbie,1 a registered nutritionist with a PhD in clinical nutrition.
You might also see it called “sel gris”, French for grey salt, due to its tonal grey colouring from the minerals.
“Celtic sea salt actually contains slightly less sodium per serving compared to regular table salt”
What are the benefits of Celtic salt?
“Celtic sea salt contains a higher content of trace minerals like magnesium, calcium and potassium compared to normal salt,” says Abbie.
“Magnesium, calcium and potassium2-4 are well-established beneficial minerals which are involved in the maintenance of healthy bones, muscle function, nerve transmission and the regulation of blood pressure,” she says.
Launa in our category team was really excited to get this trending product stocked up on our shelves and online. Here are a few reasons why...
Celtic salt is less processed
“Celtic sea salt is less processed than other salts and contains a variety of trace minerals including magnesium, potassium, calcium, iron and zinc,” agrees Launa.
Celtic salt has lower sodium content
“Despite its bold flavour, a pinch of Celtic salt has slightly less sodium content vs. table salt,” Launa says.
Celtic salt can help with hydration
“The presence of trace minerals in Celtic salt can help balance electrolyte levels and promote better hydration,” she says.
So that’s what all the fuss is about. But remember these studies are small and need to be taken with a pinch of salt (ahem). Abbie explains why.
“Although the nutritional profile of Celtic sea salt sounds promising, the evidence is lacking in regard to any additional health benefits associated with the consumption of Celtic sea salt over regular table salt, as the minerals are only present in trace amounts,” she says.
“However, the composition of Celtic sea salt doesn’t allow for adequate accessibility to the amount of minerals required by the body. So, alternative sources such as whole fruits, vegetables and grains are great options as there’s less worry of over-consuming salt,” says Abbie.
“While regular table salt is rigorously processed, Celtic sea salt is hand-harvested”
Celtic salt vs. Himalayan salt
As well as its dusky pink hue, Himalayan salt differs in origin, flavour and mineral content.
As it’s mined from the mountains in the Punjab region of Pakistan, you can imagine how this might make it different from the European shores where Celtic salt is found. Himalayan salt has a more subtle flavour and contains magnesium, calcium, potassium, iron (like its Celtic sibling), as well as other trace minerals like strontium and molybdenum.5
Celtic salt vs. sea salt
“Celtic sea salt differs in mineral content from regular table salt due to its harvesting techniques. While regular table salt is rigorously processed and refined, Celtic sea salt is hand-harvested from France and Portugal,” says Abbie.
The final say
The mineral profile sounds promising – but is it worth its salt? Compared to regular table salt, Celtic-harvested varieties certainly retain more magnesium, calcium and potassium. So if you’re already seasoning your dishes, Celtic salt is a way to up your gourmet game.
Think of it like choosing a wholegrain loaf over refined white bread, baking with the finest Belgian chocolate or choosing freshly squeezed orange juice over concentrate.
Although Celtic salt will enhance your recipes, it still does have a high sodium content. So if you’re looking for extra minerals, there are other ways to add magnesium to your diet.
