You may have heard about Epsom Salts before and wondered “What on Earth are they?” 

Epsom salt usage is becoming increasingly popular, especially among those with thyroid conditions, and there’s good reason why.

I use Epsom salts once or twice a week in a bath, and as and when I feel I need it in a foot soak, too.

What Are Epsom Salts?

Epsom salt is actually magnesium sulfate, which therefore, makes it a great source of magnesium. Some thyroid patients will use these salts in a bath or foot soak instead of taking magnesium supplements. The magnesium is absorbed through the skin and in to the body.

How Are Epsom Salts Useful for Thyroid Problems?

A  bath with Epsom salts can help you unwind and get ready for bed; relaxing muscles and leaving you feeling de-stressed.  The magnesium in the salts relieve stress by promoting the production of serotonin and reducing the effects of adrenaline. Magnesium is also important in the production of energy and helping us to feel invigorated, but without feelings of restlessness/anxiety.

Many thyroid patients (including myself) state that Epsom salts help their aching muscles and tired legs/feet, headaches and sprains. With cold and flu season underway, you could try soaking in Epsom salts as it should ease muscle aches and pains and help you get a good night’s rest. You may even recover faster. It’s been stated that these salts may also speed up healing by detoxifying your body and increasing your white blood cell count, as well as improving circulation and lowering blood pressure.

I’ve noticed that itchy and burning skin can also be alleviated with an Epsom salt bath or compress, as it helps my itchy legs.

Both magnesium and sulfate (Epsom salts’ ingredients) help to improve production and use of insulin too. Therefore, regular intake of them may help to regulate blood sugar, lowering the risk of diabetes. (Although it’s important to still have a balanced diet and not use methods such as Epsom salts in place of one!)

And although I’ve never tried it, Epsom salts can also be used as a laxative, apparently! This site suggests dissolving one teaspoon of Epsom salts into a cup of warm water and drinking it.

Other interesting uses include mixing it in to your conditioner to created a hair mask rich in magnesium, and using it to take away dry patches on skin and lips. You could also mix some of the salts in to your face wash to create an exfoliating cleanser, though it depends how coarse the salt is.

If you’re interested in giving this many-use, loved by many Epsom Salt a go, I’ve put a link to it below, where it’s currently on offer at Amazon.

    I’m due to have my first floatation tank experience at the weekend…I’m still not 100% stable on my meds (T3 mono therapy). I’m wondering if it’s a good or bad idea to expose myself to this level of magnesium sulfate. My liver is struggling at the moment too with high ALT. Any opinions?

    I use this in a hot bath and it really is helpful. For me, I usually feel the most relief the following day, as early as the next morning. I have also used it as a foot soak (hot water) to help with Achilles pain. Great stuff!
