Rated 5 out of 5 by from Amazing! I bought this brand of Epsom salt in a health food store many years ago. It was love at first use. Then, the store stopped carrying them. Oh, the horror! I am so happy (and relieved) to have found this site. As a busy mom and track coach, I take a salt bath every night to ease my aches and pains at the end of the day. I really feel a difference when I don't. My husband uses them in his recovery baths after his marathons, and my daughter after her meets. We also recommend them to the kids on our distance track team. Not to mention, they are prettiest salts I have seen. I love to combine them with therapeutic grade essential oils to make bath salts as gifts.

Rated 5 out of 5 by from Straight forward explanation and great service I was surprised at the increase in my Epsom Salt (25lb) product so I called to find out why the substantial increase. The person I spoke to explained that, after careful examination of competitors' similar products and Salt Works' free shipping policy, a price increase was inevitable. I thought about it and realized how much I love this product (use it every day in my bath since I work in my garden daily) and the convenience of having it delivered to my home with no shipping fee is certainly worth the increased cost. I am in the same state, still I ordered it yesterday and received it today. What's remarkable is that I had run out of it. How'd you know? Thank you, Salt Works.

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 An Easy To Use Product A neighbor told me he had heard about using Epson Salt on the lawn. That was the reminder that Epson Salt is a product for tomatoes. Then I went on line and found your site with an excellent summary for many uses of Epson Salt. And, I determined that you had the best price. Shipping was quick. I began using the product last Wednesday. I spread the Epson Salt with the lawn fertilizer. I have treated flowers and some of the azelias and other blumming shrubs. I will be ordering more soon. Thank you for a great product.

Rated 5 out of 5 by from Love the bulk options I’ve been taking Epsom salt baths since I was a kid. My parents swore by them!! Always bought from retail stores & it just limited me to the amount I put in a bath. Well now buying bulk at a cheaper price alows me to increase the salts without worry. I’ve heard all the benefits of these “Float Spas” but they use ridiculous amounts of Epsom salts. I recvd the product in a week and used 5 lbs in a bath. Wow the feeling I had the following day was incredible. Highly recommend this product. 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 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.
