Hi, I’m Charles Barber. Before I founded Crucial Four, I struggled with constant fatigue, brain fog, and a weakened immune system. I eventually discovered that refined salt—stripped of essential minerals—was quietly causing these issues.
That's why I created mSalt: a pure, mineral-rich sea salt harvested sustainably from pristine Icelandic waters. It made a huge difference in my life, improving my energy, clarity, and overall health.
At Crucial FOUR, if we can’t grow something ourselves, we source from trusted partners—real salt-of-the-earth people who share our values for purity, quality, and sustainability.

"I love Crucial FOUR's Icelandic Salt, not only is it tested for heavy metals and microplastics, it’s the tastiest, nutrient-dense salt I have ever had. I love adding a pinch in my water to keep my electrolytes balanced and be hydrated in the best way!"
"As a mama of six, I’m always looking for easy ways to increase my energy and keep my family healthy — this Icelandic flake salt does both! My whole fam loves it! Even my 4-yr-old asks for the “icewandic sawt” at dinner time 😆😍"
"I developed preeclampsia with my first. During the pregnancy I was extremely undernourished. I limited protein limited salt and had no idea how important minerals are in order to support healthy thyroid health. This time around I have the privilege to focus on my preconception health prioritizing good salt local meats raw dairy/cheeses and lots of honey with seasonal fruits."
"I have only been using Crucial FOUR for a couple of weeks now (sprinkle in water every AM), but can already tell a difference in less water retention and feeling more hydrated overall!"
"I learned about this salt through a fellow chiropractor who did research on the amounts of lead in different salts. This one was the most pure! I checked it out, loved the website, and now I add it to all my water and meals. I even use it in my morning smoothies!"
I love the clean crispness of the salt, and the unusual shape makes it easy to pinch from the salt bowl that I keep near the stovetop. The % of minerals though is why I bought it.
Purchased because of the 3rd party testing for heavy metals, microplastics and purity. So much celtic salt has a toxic ingredient profile. Use it for morning hydration and in my pre-workout daily as well as my food. Happy to find this essential product to include in my daily diet.
I have been looking g for a good clean mineral Salt for a while. Thank you for this product....love it.
I got it in just a few days!!
SO FAR SO GOOD
This salt is so good! In the morning I pop a little under my tongue or add it to my water and I also add a pinch to my smoothy. I love knowing I’m getting the minerals I need!
This product truly has been amazing! I feel so much better and have more energy since using the Msalt and can’t wait to try other products.
