Rated 5 out of 5 by from Best Salt For Recovery On The Market I own a boxing gym and was gifted a 50lb. bag of Ultra Epsom Salt (Extra Fine Grain). All of my fighters soak with it to reduce their muscle soreness and speed up recovery. This stuff is the best on the market. I also soak my body twice per week for 30 minutes as I suffer migraines from a lack of magnesium. My body absorbs magnesium optimally transdermally (through skin). I give this product 5 stars because of what my entire gym and myself have experienced over the last 2 years of using it. Our fighters recover faster and my migraines are gone.

Rated 5 out of 5 by from Best Epsom Salt Ever! I purchased this salt in store but then they stopped carrying it. (What? I know, right!) I'm so happy to have found this site because now I can buy my favorite salt in 4 different grains. Say it isn't so...but it's true. I use the fine grain on a daily basis for bathing. I feel a difference in my body when I don't. I plan to make holiday gifts with this course grain. It's the prettiest salt out there too and I can't wait to see it displayed in decorative jars. Thanks Saltworks!

Rated 5 out of 5 by from Best for fibromyalgia I have frequent deep muscle and joint pain due to fibromyalgia. When my symptoms assert themselves, I soak in a very hot bath with 6 to 8 cups of this extra fine epsom salt and the next day I can function again. It's so fine that it dissolves quickly and it feels much cleaner in my body than the grocery store epsom salt I had been using. I live on an extremely limited budget but I make cuts elsewhere so that I can afford 50lb bags of this stuff. If I don't use it, I suffer.

Rated 5 out of 5 by from Soothing I have an autoimmune disease that has attacked the muscles in my lower body. After doing my therapy, my doctor advised me to soak in epsom salt with a few other ingredients and it makes the difference between functioning and not functioning after therapy. I just ordered my second go around with 2 25# bags since the 50 wasn’t available. This has been a big help to my feeling better so I appreciate the process and the time it takes to put on the market. Thank you.

Rated 5 out of 5 by from perfect texture for gardening I am so pleased with the large coarse granules of Epsom Salt which are perfect for my 1500 sf organic home garden. Previous to finding this online, I was buying 2 or 3 small bags at the local Walgreens. But finally I have a 25 pound bag in a convenient coarse grain! the other stuff would too easily blow away in the wind otherwise be difficult to handle. The Saltworks order came lickety-split and in perfect condition! I will definitely be back for another order!

Rated 5 out of 5 by from This stuff is magical I have been buying and sharing 50lb bags of Epsom salt from salt works for a few years now. It is effective beyond another brand I have used plus it is beautifully fresh anf clean. My aches and stress melt away in every bath. Using it in compresses with turmeric has healed my own skin occasional eruptions AS WELL as healed abscesses on our cat and several dogs I have cared for over the years. This is a solid buy and I hope I can access it for the rest of my days.

Rated 5 out of 5 by from Consistently excellent in both product and service We own a massage therapy practice and we give take-home epsom salt packs and bottled water to every client after each massage session. After trying several brands and types of salt, we found SaltWorks products to meet our needs, in terms of quality and price. The convenience of ordering in bulk sizes can't be beat, especially with free shipping options. The quality of the salt is awesome - the large grains are fabulous! We cannot recommend them enough!!!
