Years ago I tried Epsom salts for the first time after hurting my knee, hoping they would speed up my recovery. I’d heard they can ease joint pain and help with injuries, among other benefits. But how true are those claims?
I didn’t think much about it at first. After I received a PR sample of Westlab Epsom Salt, I decided to dig deeper. Below I cover what Epsom salts are, their uses and benefits, whether you can drink them, and whether they’re worth trying. I also share my thoughts on Westlab Epsom Salts and where to buy them.

What is Epsom salt?
Epsom salt (properly called magnesium sulfate) gets its name from the English town of Epsom, where mineral water was boiled down to leave this compound behind. Many people add an “s” and say “Epsom salts,” but it’s really just one type of salt—magnesium sulfate.
Epsom salt uses and benefits
For centuries people have used Epsom salt believing it can ease joint pain, relax sore muscles, and pull toxins from the body. Some use it to support detox or weight-loss routines, while others use it to help skin conditions like eczema and psoriasis.
It’s also said to benefit the heart by improving circulation and reducing blood clot risk, which could lower chances of sudden heart events. Some celebrities, like Gwyneth Paltrow, use Epsom baths for relaxation and to reduce bloating.
Can I drink Epsom salt?
You can drink Epsom salt, but only if it’s food grade. Some people use it as a laxative or to cleanse the colon, but there are risks. Drinking too much can cause serious, even life-threatening side effects.
Don’t drink Epsom salt if you have stomach issues, are pregnant, or have kidney problems. Always check with your doctor first. If you do take it, dissolve it in plenty of water (at least 8 oz / 250 ml) and add a little lemon to improve the taste.
The truth about Epsom salt
While researching, I found an article by science writer Paul Ingraham that questions many of the common claims about Epsom salt. The reality is that strong scientific evidence is limited for many of these benefits.
One often-cited study is from the University of Birmingham (2006) by biochemist Rosemary Waring. It tested whether magnesium from Epsom baths is absorbed through the skin. Volunteers had their magnesium levels measured, then bathed in Epsom salts daily for seven days. After the experiment, 16 out of 19 participants showed increased plasma magnesium. The study concluded:
“Bathing in Epsom salts is a safe and easy way to increase sulfate and magnesium levels in the body.”
I’m glad this study found a benefit, though some people question its strength. For me, the possibility that Epsom salts can raise magnesium levels is reason enough to keep using them. Magnesium helps regulate calcium, supports bone strength, and is important for muscle and heart function. After being diagnosed with calcium deposits in my knees, I hoped extra magnesium might help. My knees have improved, likely from a mix of healthy eating, exercise, and possibly Epsom salt baths.
Should you be using Epsom salt for the claimed benefits?
Some people say Epsom salts have helped their health issues, and I’m open to that. Lack of extensive studies doesn’t necessarily mean they don’t work.
If you’re curious, try them and see if they help with bloating, muscle aches, or other minor issues. But if you have a specific health condition, talk to your doctor before starting any new treatment.
Westlab Epsom Salts review
Now for my thoughts on Westlab, a UK brand known for bath salts. Their Epsom salt is 100% natural and high-grade. It’s sold in Boots, and you might also find it in TK Maxx and Home Bargains.
Westlab Epsom salt is unrefined and cleaned without chemicals, so there are no additives—just pure magnesium sulfate. I got one 1 kg bag and used it for two baths, adding a few drops of essential oil to make the experience more relaxing. You can get at least three baths from 1 kg if you use less per soak—500 g per bath isn’t necessary.
These baths really help sore muscles and achy joints after heavy workouts. I’m not sure whether it’s the hot water, the Epsom salt, or both—but I feel better afterward. I’ll be buying more, and it’s handy that I can pick it up at Boots or Home Bargains. If you prefer online shopping, Westlab Epsom salt is available on Amazon, Holland & Barrett, and Look Fantastic—buying in bulk can save money.
Are you a fan of Epsom salts? Have you tried Westlab?
