Answer:
Himalayan salt and other specialty or gourmet salts from ancient mineral deposits, as well as Hawaiian, Mediterranean, and French sea salts, and Australian river salts, have become popular due to their flavor and suggested health benefits.
One potential health benefits commonly ascribed to these salts is that they have higher concentrations of essential minerals (like calcium, iron, potassium, and magnesium, and chromium) than ordinary table salt (purified sodium chloride). However, the amounts are fairly small. In addition, concerns have been raised about contamination of these salts with heavy metals such as lead, cadmium, arsenic, and mercury, as well as microplastics.

October 14, 2019How do microplastics get into Himalayan salt. Are they not mined from a dry source?
A good question. The answer is, apparently, from plastic fibers in the air that have settled on the salt once exposed and during processing, as evidenced by the fact that most of the microplastics are fibers (which move with air) as opposed to particles (which are more commonly found in water and sea salts).

October 02, 2019Kala Namak is called black salt but the quantity I have in my kitchen is actually pink (lighter color). Does CL consider this a dark salt?
I would be interested to also see concentrations of fluoride in various salts if that is ever considered in testing. Thank you!
Hi Karen - According the the analysis we link to in our answer, Kala Namak is considered a "darker" salt -- it is described in the analysis as "light brown with black specks."

October 26, 2018What about plastic particles evident lately in ocean waters and consequently in the salt minned from those waters?
what is the damage that can be expected from those particles, small enouge to invade blood stream?
Hi Jehoshua - We've added information about microplastics in salt, including Himalayan salt, in the answer above. Please also see this CL Answer: https://www.consumerlab.com/answers/plastic-particles-in-drinking-water-and-salt/microplastics-water-salt/

March 28, 2018When I was in my teens, my dermatologist told my mother to switch me off of Iodized salt to plain salt, which we did. At the time (early 60's) the Docs said that chocolate was an acne trigger too, so I stopped eating that as well. I've always wondered what was in tihe Iodized salt that was thought to be bad for teenage skin.

March 26, 2018Some Australian doctors have embarked on a campaign to add iodine to salt consumed in the Himalayas in an effort to wipe out cretinism that persists in many Himalayan villages due to the lack of iodine
Thank you for posting about this, Gerhard. We found an article about this at http://www.abc.net.au/catalyst/stories/s1497255.htm. A very dramatic story and certainly emphasizes the value that iodized salt can play, and the fact that specialty salts are typically non-iodized.

January 03, 2018I am more interested in the study showing plastic particles in sea salt. We have no idea, as far as I know, what ingesting microparticles of plastic is doing to us. I started using land salt (Himalayan) for that reason.
Another thing I've wondered about is the difference in saltiness for foods seasoned with coarse salt as opposed to finer salt. It seems to me that the palate would get less salty flavor from the coarser salt -- you'd swallow more salt untasted, leading to higher sodium intake.
Hi Virginia - Please see the information we've added about microplastics in salt, including Himalayan and sea salt, in the answer above.

May 02, 2025I have to be careful to add less coarse salt than I think I need when cooking. We always put coarse salt in a grinder for table use to avoid the scenario you describe.

August 02, 2017Regarding iodine in salts, I've read that when sea salt retains its original ocean moisture it still retains some iodine, but if it is dried the iodine "gases off". Is this accurate?
( there was also some speculation of trapped algae or kelp and some sea salt but I think that's pretty rare.)
Hi Robert - We don't know the answer to your question but, most important to us is what is in salt as it sold. Kelp will certainly contain iodine -- see our report at https://www.consumerlab.com/reviews/kelp-supplements-review/kelp/.

August 02, 2017Fortunately more and more people have access to whole, wet, 'unrefined' sea salts, not enough people as it's mostly in small and large 'health food' stores but many more in recent years (maybe Trader Joe's and Costco have caught up, they eventually do).
The same can be said about availability of "complexed" or "mixed" antioxidant and carotenoid supplements and many other more "whole" foods and nutrients.
Over purification of just about anything in nutrition seems to be a tricky road to follow (see the botched Beta-Carotene and Alpha-Tocopherol studies that actually might have led to the deaths of some of the test-subjects.)

August 02, 2017I would speculate that the immediate solubility of salts and the very quick availability of the ionic trace minerals, as compared to other foodstuffs, could be an important factor in why these trace mineral balances are important even though they are seeing at these relatively low levels compared to other food sources which seem to require many more complex steps to make their nutrients available. They also provide trace elements but, I would guess, in a delayed fashion in comparison to salts and perhaps at other, later stages of digestion rather than the immediate and continued absorption and interactions from, especially, "whole" salts.
(I’m excited to see if there are opinions and answers to my speculations here on this highly informed forum of wonderfully interested people!)

April 23, 2017When I found the 5 lb container of Himalayan Pink Salt I purchased had a lot of grit in it the company sent me a replacement which seems to be better so far.

February 13, 2017It is disappointing that you compare Sea Salts etc. to the minimum daily requirement and not to purified Sodium Chloride.
If you read the full answer you will see that table salt (which is processed to reduce amounts of compounds other than sodium chloride) was also tested and is compared to the specialty salts.

February 13, 2017What about Yellowstone Natural salt hand harvested from pure mineral spring water any reviews just started using. Company Est. in 1957
gloria7984
March 28, 2018The important thing is, does the salt contain added iodine? If not, you may risk developing an iodine deficiency and subsequent health consequences.

February 13, 2017I have been using Real Salt for about 10 years now and i am also interested in knowing if i am wasting my $$
Kent7981
May 21, 2017If you enjoy the salt and it's flavor compared to table salt then your not wasting your money. The Real Salt or any other specialty salt is obviously going to test similar. I personally like the less processed salts.

June 19, 2019I'm wondering about Real Salt also.

February 12, 2017Regarding the iodine need that you mention- is kelp an adequate source for those who avoid salt for whatever reason? What dosage ?
Also I have read recently that sometimes perople who try to avoid salt (in whatever form) may be harming themselves if they do not have a medical condition that warrants salt reducion. It's confusing!
Kelp can be a good source of iodine. ConsumerLab.com is currently testing kelp supplements for iodine and will publish results in 2017. However, as noted in the full answer above, you may already be getting adequate iodine form your diet, even without salt.

February 12, 2017Dairy products only have iodine in them if the cows udders are cleansed with iodine, which isn't used much for that purpose anymore.
Gaks
July 17, 2018consumerlab, is this true? should those of us who use non-ionized salt no longer rely on dairy for daily iodine? clarification would be immensely helpful.
