EPSOM SALTS – MAGNESIUM SULFATE…Relax, Repair, Replenish, Restore

EPSOM SALTS – MAGNESIUM SULFATE…relax, repair, replenish, restore 
By Matthew Craig, bounceREHAB Principal Physiotherapist








‘BOUNCE SALTS’ are now available for you to dispense 2 kg refillable bags in-clinic or for easy purchase from our online store (http://www.bouncerehab.com.au/shop). Our salts have an extremely unique selling point.
Our salts are:

  • Food Grade Natural Epsom Salts -Magnesium Sulphate. They are rare and special.
  • 100% Natural deposits of Epsom Salts from Germany, used by compound chemists worldwide.
  • Can be used (< 5 days in a row) while pregnant and/or breast feeding.
  • For anti-inflammatory and antispasmodic effects.

Whilst there is not a huge amount of medical research on the subject of Magnesium Sulphate (MgSO4) bath salts, the benefits of Epsom salt aren’t just folklore. In fact, several studies have demonstrated the profound and wide—ranging benefits of magnesium and sulfate, naturally occurring minerals that are the two major components of Epsom salt. Doctors, celebrities, personal trainers, gardening experts and supermodels have all extolled its virtues.

The salts that are sold to our patients at bounceREHAB are natural and ‘organic’ (sorry, I had to throw this buzz word in), mined in Germany and of the highest level of food quality and medical grading. This means that you can safely ingest the product by mouth if you are in the bath, but I would advise against drinking a lot of it because in high enough doses it is demonstrated to have a very effective laxative effect.

So because we sell so much of the stuff to compliment our treatment sessions, I have put together a quick blog for those interested in learning a bit more about Epsom salt—from why it works to how to use it for health and beauty and even gardening. We think you’ll be as amazed with this natural alternative as we are, even after all these years.


Epsom salt, named for a bitter saline spring at Epsom in Surrey, England, is not actually salt but a naturally occurring pure mineral compound of magnesium and sulfate (MgSO4). Long known as a natural remedy for a number of ailments, Epsom salt has numerous health benefits as well as many beauty, household and gardening-related uses.

Studies have shown that magnesium and sulfate are both readily absorbed through the skin, making Epsom salt baths an easy and ideal way to enjoy the amazing health benefits. More for the geeks http://pursuitofresearch.org/2012/07/09/epsom-salt-baths-for-therapeutic-use-and-detox/


Magnesium plays a number of roles in the body including:

  • Regulating the activity of over 325 enzymes,
  • Reducing inflammation,
  • Helping muscle and nerve function
  • Helping to prevent artery hardening and blood clots
  • Improve mood, calm the mind
  • Eases stress to relax ‘wind down’ the central and peripheral nervous systems.
  • Improve sleep and concentration
  • Relieve migraine headaches
  • Improves absorption of nutrients
  • Makes insulin more effective
  • Improves oxygen use
  • Helps joint proteins, bone tissue and mucin proteins

Magnesium helps to regulate the activity of more than 325 enzymes, and performs a vital role in many bodily functions, from muscle control and electrical impulses to energy production and the elimination of harmful toxins.  It improves nerve function by regulating electrolytes and is necessary to maintain proper calcium levels in the blood.  Excess adrenaline and stress are believed to drain magnesium,  a natural stress reliever, from the body.  Magnesium is necessary for the body to bind adequate amounts of serotonin, a mood elevating chemical within the brains that creates a feeling of well being and relaxation.

Sulfates help improve:
  • The absorption of nutrients,
  • Flush toxins
  • Build proteins
  • Help ease migraine headaches.

Sufficient sulfur is essential to detox the body of toxins and waste.  Low levels may lead to a ‘backlog’ of toxins, which in turn can affect our central nervous system.  Most sulfur supplements are difficult for the body to absorb and therefore have minimal effect.  However, Epsom Salt provides sulphates in a readily absorbable form to help the body rid itself of waste products and toxins by making them water soluble and therefore easily excreted.

Lots of detail for 10 big benefits of magnesium:


mag deplete






  • High intake of fat or calcium in the diet
  • Prolonged periods of stress – physical and/or mental stress
  • Certain allergic or inflammatory bowel diseases like celiac disease or Crohn’s disease
  • Kidney problems
  • Thyroid issues
  • Advanced age
  • Overconsuming alcohol
  • Diabetes
  • Severe burns
  • Certain antibiotics, diuretics and reflux medications

Stress 1

New patients often come to me with symptoms of magnesium deficiency as part of their health puzzle–muscle cramps and twitches, constipation, headaches, sleeplessness and anxiety. Eating magnesium-rich foods and supplementation usually helps. But if the patient is dealing with non optimal mineral absorption from food, oral magnesium intake may not be enough. Try adding a bath regularly with MgSo4 salts to your busy routine.

mag injury










  • Warm water temperature (not boiling hot)
  • 1-2 cups (250-500g)
  • 12-50 minutes duration

Therapeutic bath salts for the relaxation of muscles, elimination or reduction of muscle spasms, and for the overall enhancement of a person’s mood. The bath salts are used in the convenience of a bath and the internal mechanisms of ingested medication. The formula for the composition of the salts includes a selected amount of magnesium sulfate. The user mixes a preselected amount of the crystallized salt with the bath water (we recommend 1-2 cups). A period of time is allowed to elapse before the user departs the bath (we recommend 12-50 minutes). By resting in the tub, the user accrues the combined benefits of external therapy and internal therapy.

After the allotted time, the user experiences relaxed muscles, elimination or reduction of muscle spasms, arthritic pain and swelling, and an overall enhanced feeling of well-being by alleviating depression and related moods. Your skin is also feeling silky smooth and looking toned, fit and shiny.


Picture: Most children respond to an ES bath by appearing happier, more relaxed. Some parents report that their children are more responsive, more “with it”. Some parents who give the bath in the evenings report that their children are able to get to sleep easier, and have a more normal sleep pattern. My children (Indigo 6 years and Violet 2 years of age) enjoy the benefits of Bounce Bath Salts EVERY night.

The bath salt provides treatment for muscular aches and pains brought about by overexertion. It is a great recovery tool for our runners, cyclists and for those performing prolonged sitting duties (straining muscles) at work. It also provides relief from various rheumatic disorders such as fibromyalgia.

Call me a conspiracy theorist, but I believe that the reason that the FDA hardly approve any research on MgSo4 has been performed at a high level is because MgSo4 salts are a threat to the profits of big pharma. They are cheap, have little side effect (safe) and can be easily purchased by consumers. There is nothing in it (ie $$) for the pharmaceutical companies as they wouldn’t sell as much pain killers or pain pills. That’s enough Matt…rant over.


Any Epsom Salt left on the skin may continue to be absorbed as long as it is still on the skin, offering continuous ‘timed-release’ input into the bloodstream  –  like medication given through skin patches.
Some people who desire the wonderful therapeutic benefits from bathing in Epsom Salt but have a pre-existing skin conditions such as eczema find adding oils such as essential oil, olive oil or others to the bath prevents further skin irritation that may otherwise result.


Extensive research shows that magnesium lessens pre-eclampsia, in which blood pressure soars in late pregnancy, upping the risk of spontaneous abortions and premature, low-birth weight babies.

A large British study of 10,000 women in 33 countries confirms that taking magnesium reduced the hazard by 50%. A study in the Journal of the American Medical Association reported a 70% lower incidence of mental retardation, and a 90% lower incidence of cerebral palsy in children of mothers using magnesium during pregnancy.
