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 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 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!!!

Rated 5 out of 5 by from So convenient! I was making an extra stop to pick up Epsom Salts. It is much nicer to have a large bag delivered -- and for less per pound than at the local drugstore.

Rated 5 out of 5 by from Best quality and most affordable I have ordered from Saltworks twice and recommended it to friends. Adding epsom salts to every bath is a must, and Saltworks has the most affordable prices I've found. My body soaks up allllll the magnesium I need, which most people are deficient in. Thanks for keeping me healthy Saltworks!

Rated 5 out of 5 by from Amazing Quality! I have been using this for years and recently gave a couple pounds to my son who is an Electrician/Mill Right. He started taking baths with it and said it relieves all the aches, pains from his physical work life!
