Rated 5 out of 5 by from Salt Baths & Beautiful Skin My husband and I love the SALTWORKS Medium Grain Epsom Salt. We use it every time we take a tub and we love it. I usually put a few drops of essential oils like lavender, orange, or peppermint directly on the salt to emulsify it and we have a luxurious and relaxing bath. On occasion I also add other moisturizing oils such as jojoba, olive or sweet almond with the essential oil and the salt for even more pampering. Thanks for such a great product. Your shipping and ordering process is simple and our salt always shows up quickly. Keep up the great work!

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 Great for soaking I have been buying this product for the last year. I work outside on my property, 3 acres. I have nut trees as well as citrus trees plus a large vegetable garden. When I go into the house after working outside for 4 to 6 hours my back and feet usually are hurting so I soak in the tub with Epsom salt. Everything feels so much better when I get out of the tub. I am 72 and do almost all the outside work by myself. Have a handyman who helps with the very heavy work but I do all the mowing, tilling, planting and harvesting by myself.

Rated 5 out of 5 by from LOVE! My DIY nightly ritual. Sleep great and detox at the same time. In a container I mix well: 1 cup epsom salts 1 tbsp skin nourishing carrier oil 1 tbsp Dr. Bronner’s liquid castile soap or fragrance free shampoo (You will likely find the shampoo to be the better choice) 3-6 drops essential oil (Depending on whether you are bathing yourself or a child) I prefer Avocado carrier oil & Lavender essential oil for a sleepy time nourishing bath. I only use Dr. Bronner's brand to avoid any clumping.

Rated 5 out of 5 by from Wonderful Product! I have been using Ultra Epsom Salts for several years. When purchased in the 50 pound size, it is a fraction of the cost of the lower quality stuff at the local discount super store. We have a decorative container beside our tub and these salts make the perfect bath salts. We fill the container half full, add a few drops of essential oils, quick stir, then repeat. After sitting overnight it becomes a fragrant bath salts we use by the "double scoop" for a wonderful, relaxing, end to our day.

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 Favorite bath salt! I have been buying Ultra Epsom Salts in bulk now for a few years. I have tried all of the fine, medium, and coarse grain varieties. They are all great, and I love putting the medium and coarse grain salts in easy-to-reach colored glass jars that complement the decor. I gave some to my mother-in-law when she was having issues with itchy skin due to medications, and it really helped and provided relief for her. Now I buy a 50 lb bag for both of us whenever I reorder.
