"Most salts have heavy metals and microplastics. I was so pleased to find out this has none."

There's no doubt about it; the average salt contains tons of heavy metals and microplastics. 

These can lead to stress, adrenal issues and inflammation, just to name a few. 

But what if there was a pure form of salt that delivered the same great taste?

You would be able to enjoy both the taste and many benefits of salt, but without having to worry if it contains microplastics or heavy metals.

...And best of all: Our Pure Polar Sea Salt can help out those with adrenal issues. 

That would be pretty awesome right? A microplastic and heavy metal free salt, that also helps your body function even better than before.

We are Crucial Four - and we product micro-plastic free foods that supercharge your metabolism and improve your health.

...So you can feel your absolute best, all day every day.

Truly love the taste and impact - has become one of the only salts I'll use.

Great Taste. No Drawbacks.

Our pure polar salt can be used in a variety of recipes. From adrenal mocktails and kale to ribeyes and gluten-free pies, mix, cook, top, and bake with these microplastic-free flakes.

Sustainably Hand-Harvested

As nature intended, it’s dried by the sun and wind without machine processing. Hand-harvesting maintains the crystalline structure of the salt crystals. 


A totally renewable resource (unlike mined salts), passing through ancient sea shell beds increases magnesium, potassium, and calcium.*

Polar Pure

There is no industry, tourism, or recreation happening on the beaches where our pristine salt is hand-harvested due to the treacherous current and freezing temperatures

Addresses Adrenal Issues

Our Polar Pure Sea Salt is very rich in magnesium, which is an essential mineral for the human body.


It has helped thousands of people with adrenal issues feel better every single day.
