Bought this after reading the reviews to see if it's as legit as people are claiming. I love epsom salt baths but somehow had never tried magnesium chloride bath salts, so it made sense to try. I'm a big believer in the power of a good bath, so tend to collect new oils and bath salts to keep me healthy & glowy. My top “seriously wow” / fairly life-changing products have long been 1. Vitamin E oil, (great for dry skin & hair- tho-it's often tough to find, I mean the kind without carrier oils added!) 2. Coconut oil is also the best to make my skin dewy and soft, ntm hair shiny 3. Tea Tree Oil (has antibacterial, anti-inflammatory, antiviral, and antifungal properties, so adding a few drops to your bath will help keep colds, viruses & infections away, ntm your hair and skin will be healthierâ€"great for blemishes as well, just be cautious that if you don't dilute well w carrier oil or water it may sting! don't ingest or get in eyes!) 4. Epsom salts for detoxifying, though my fave bath salts have been Dead Sea salts (Ahava specifically has a great product that makes my skin glow, when you can find it for reasonable price) I've also recently added olive oil, grape seed oil (great to keep hair thick/ prevent hair loss! Just make sure to use Cold pressed, extra Virgin, organic!) & apple cider vinegar on occasion. Those are just some quick tips for those who care- but this product more than any other I've used has helped with back pain and aches. I also make a magnesium oil like other reviews suggest and spray on pain sites when when I have back aches or feel icky. Both as an oil and in my bath it makes me very sleepy and relaxed right away, and I only use a handful or so. I make some of the magnesium oil for my stepdad who had knee surgery and he uses it often for pain, so I guess it works for tougher stuff as well. I'd assume any fairly potent magnesium chloride product will work, but the price for the big tub of it being $20 is v reasonable and I agree with most of the reviews here. I liked it so much I divided it up and gave it to a few neighbors, family & friends in little glass jars to try. It also makes my hair and nails really strong btw when I use it in bath. My nails are very brittle usually, prob from all the soft drinks I have, but when I use this they're strong for weeks on end. Anyway, I've added this to my top faves and definitely recommend. Have a feeling it would also keep a person healthier as opposed to not using. Good product and very pleased :
