Ultra Epsom Salt (Extra Fine Grain) is rated 5.0 out of 5 by 321.
Rated 5 out of 5 by from The Best. I've been ordering Ultra Epsom salts from Salt Works for a year + now. So glad I found them. I use ALOT of Epsom salts, I bathe with it every night. I put it all over my grass and garden; simply put the fine or extra fine into a fertilizer pellet dispenser and walk it all over your yard. Don't worry chickens and animals won't mistakenly eat it (they are smart). For flowers and veg, dissolve about a cup to a gallon of water and spray them or simply work granules into the soil (people can not believe how lush my garden is :) I can tell you there IS a difference in epsom salt quality. Saltworks provides the highest quality and free shipping is, well, really such a nice bonus. I also have purchased many of their other salts for bathing and culinary use. Simply the best. THANKS SALTWORKS!

Rated 5 out of 5 by from Best Buy for any athlete...beginner or Pro Ultra fine dissolves quickly in our home jacuzzi tub for a super relaxing experience. Soothes sore muscles after intense workouts and leaves NO residue in the tub. This is the only company I go to for bath salts. Why pay $8 for a 1 lb bag at WF; when a 50# bag is $43 with free shipping.....An absolute no brainer. I order one for myself (I don't share with my weight lifting husband or athlete teenagers.....get your own!)....every 6-9 months. I get the best product on the market at the absolute best price. I wish everything in my life were this easy!

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 Excellent product! I first bought a 25 pound bag, and recently just purchased a 50 pound bag since I love this product so much! I have been having issues with my feet, so I soak my feet daily in one cup of these wonderful salts, typically in the evening. You can Google all of the benefits of Epsom salts and magnesium. I love my soaking routine so much, that I am gifting all of the girls in my family with 2 cups of salts in a purple decorated Ball jar, so they can discover the wonderful soothing and healing qualities these salts offer.

Rated 5 out of 5 by from Dissolves quickly, cheaper than the superstore I've bought salt from Saltworks for a few years now. I like the selection and have tried several sizes. It is also less expensive to have it shipped across country than it is to buy a pound at a time locally. I like the extra Fine Grain for soaking my tired muscles in the tub. It also disperses very easily as an ice melter. Larger grain salts melt the ics on the drive okay, but they get stuck in the treads of shoes and can get brought back into the house and damage floors. The Extra fine gets left on the door mat.

Rated 5 out of 5 by from Quality, Quality, Quality! First of all, who doesn't love samples!? The salt sample I received was a cooking salt (Alder Smoked Sea Salt) and it is Absolutely Delicious! The delivery wasn't as quick as others stated but it was worth the wait. The Epsom salt is by far the best quality salt I've used thus far. Other brands just don't compare. Very happy with my purchase. I won't be buying my Epsom Salt from anywhere else. Definitely going to purchase Cooking Salts as well. Very happy with my purchase and sample :)

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.
