The mineral mixture,
named for a saline spring in England, is actually a combination of magnesium and
sulfate. This popular mineral is touted for its health benefits as well as uses
in cleaning and gardening projects.
Epsom salt, or magnesium sulfate, is a natural compound that
people claim can treat constipation, relieve pain, and relax
muscles. However, research into its therapeutic use is
limited.
Epsom salt is a naturally occurring compound that people may
refer to as magnesium sulfate or bath salts. It is a common
ingredient in several complementary therapies, such as baths and
exfoliants.
Despite its name, it is a completely different compound to table
salt, although it may resemble it in appearance. People may
recommend diluting Epsom salts in water to create a bath, or an
oral solution.
In this article, we discuss the uses of Epsom salt, its
benefits, possible side effects, and more.
Epsom salt uses
People sometimes soak their bodies in Epsom salt baths or drink
Epsom salt after dissolving it in water. A person with any
underlying medical condition should speak to their doctor before
trying Epsom salt. People living with kidney disease must not
consume Epsom salt.
The Food and Drug Administration (FDA) approves magnesium
sulfate in a limited
number of instances
Trusted
Source, including the
treatment of:
hypomagnesemia (low magnesium)
constipation
prevention of seizures in eclampsia/preeclampsia
acute nephritis in pediatric patients
minor cuts or bruises
Some people claim that bathing in Epsom salt solutions allows
the skin to absorb the magnesium while providing the local pain
relief of warm water soaking. However, there is little to no
evidence to back up these claims.
Treating constipation
Magnesium sulfate has FDA approval for the treatment of
constipation.
As a result, many people use Epsom salt solutions as an oral
laxative to treat constipation at home. This treatment
method involves dissolving a small amount of Epsom salt in
water and drinking the mixture.
Improving exercise performance and recovery
People may claim that taking an Epsom salt bath post-exercise
can aid in recovery. Warm baths post-exercise may enhance muscle
recovery, but the effects of diluting Epsom salts in these baths
are unclear.
Research does, however, support claims that magnesium
supplementation can aid performance and recovery. Older
studies show that ensuring adequate magnesium intake may aid
in aerobic and nonaerobic performance and energy metabolism.
A 2024
literature review
found that
physically active individuals benefited from supplemental
magnesium. Researchers concluded supplemental magnesium may have
a positive effect on muscle soreness, recovery, and performance.
Epsom salt is rich in magnesium, which is essential for athletic
performance, but there is little evidence to suggest that
bathing in such a solution will provide these benefits.
Pain relief
Some proponents of Epsom salt soaks claim that it can aid
muscular pain relief. It is true that magnesium supplementation
may help treat some pain symptoms in those with a chronic
deficiency, and warm water bathing may help reduce muscular
pains.
However, there is no evidence to suggest that Epsom salt baths
can provide a combination of these benefits.
Sleep
There is a link between dietary magnesium intake and sleep
quality. A 2017 review notes that having low levels of magnesium
could harm a person’s quality of sleep and, additionally, their
ability to cope with stress.
As a result, some people claim that oral Epsom salt solutions
and Epsom salt baths may aid in these endeavors. However, there
is no research to support these claims.
Side effects
People may not experience any side effects after taking an Epsom
salt bath. However, people with sensitive skin could develop a
skin rash or contact dermatitis.
The following people should avoid consuming Epsom salt orally as
they may experience unwanted and potentially dangerous side
effects:
people who are pregnant
people who have kidney disease
people who have heart
disease
children
If a person drinks Epsom salt, they may experience the following
side effects:
dizziness or fainting
upset stomach
diarrhea
blurry vision
changes in bladder habits
irregular heartbeat
difficulty breathing
muscle weakness
extreme fatigue
How does Epsom salt differ from salt?
Epsom salt, also known as magnesium sulfate, is a naturally
occurring compound containing magnesium, sulfur, and oxygen. Its
crystalline structure is similar to that of common table salt or
sodium chloride.
Epsom salt is unlike table salt as it tastes bitter and is not a
suitable ingredient for cooking. People use Epsom salt for its
supposed healing and detoxifying properties.
How does Epsom salt work?
The theory suggests that dissolving Epsom salt in water helps the skin
absorb magnesium ions. These regulate numerous essential bodily
functions, including muscle and nerve function, blood
pressure, and inflammation.
However, there is not enough scientific evidence to support the
claims that the body absorbs magnesium ions through the skin.
Scientists need to perform more in-depth studies to confirm the
effectiveness of using Epsom salt to treat various ailments.
How to take an Epsom salt bath
If a person is unsure about how to use Epsom salts in their bath,
they can follow these steps:
Use 2 cups of Epsom salt for a standard-size bathtub.
Pour the Epsom salt into warm running water.
Soak in an Epsom salt bath for 15–30 minutes or up to 1 hour.
A person may consider adding the following essential
oils to help them relax and get to sleep:
lavender
rose
bergamot
jasmine
eucalyptus
Drinking Epsom salt
If a person drinks Epsom salt, they could experience a laxative
effect, which may help relieve constipation.
Adults should combine 2–6 teaspoons (tsp) of Epsom salt with 8
ounces of water and then drink. When people drink small doses of
Epsom salt, they may not experience any side effects.
Summary
Epsom salt is a natural remedy that may help relieve muscle pain,
inflammation, and constipation. However, there is not enough
scientific evidence to support these claims.
Epsom salt is generally safe for most adults and children. However,
certain people should avoid drinking Epsom salt solutions. Consuming
Epsom salt can lead to side effects, including diarrhea, irregular
heartbeat, and muscle weakness.
People should talk with their physician before consuming Epsom salts
for constipation relief.
