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 Great! Very pleased with the quality of the salt. I’m 9 months pregnant and this is the only thing that has helped my back and foot pain. Nice packaging and fast shipping.

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 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 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!
