The Best Epsom Salts

You probably grew up seeing Epsom salt in your parents' or grandparents' bathroom but it wasn’t until adulthood when you finally appreciated it. The magic of Epsom salt is its soothing effect on sore, tight muscles. With just a cup or two sprinkled in warm water and after soaking for 20 minutes, the body can feel totally different. You can opt for a regular, no-frills bag of Epsom salt or buy the variety that includes the addition of good-for-you ingredients like tea tree oil, eucalyptus, or peppermint. Also, while some quality brands can be a bit expensive, you can also find great deals on this product that should be in everyone’s bathroom.

How do I use my Epsom salt?

Taking advantage of Epsom salt is as easy as adding the product to a warm tub of water. The salt flakes will dissolve, making it easier for your body to absorb the compound and reap its therapeutic benefits.

Does Epsom salt expire?

You may notice an expiration date on your bag of Epsom salt but it doesn’t generally expire. The salt may get clumpy or hard over time, but you can easily break up the clumps or dissolve them in water.
