In my understanding, anything from the earth that has minerals, is also going to have some heavy metals like our food supply. It's kind of a 'catch 22'. The epsom salts help to increase sulphation and improve our ability to detox, however they also do contain trace amounts of the heavy metals we need to detox. Make sure you get the kind that specifies, "For human consumption" from the pharmacy section. They usually have a decreased amount of heavy metals-compared to the ones used for fertilizers at the garden shops. We can not avoid all exposure. We'd have to stop eating fruits and veggies if we were going to try. This is one reason why increasing our ability to detox these toxins is so important.
We used epsom salts almost every night for 5 years and only saw good with it's continual use. So I felt very confident in using them.

Researchers and physicians report that raising magnesium levels may:
Improve heart and circulatory health, reducing irregular heartbeats, preventing hardening of the arteries, reducing blood clots and lowering blood pressure.
Improve the body's ability to use insulin, reducing the incidence or severity of diabetes.
Flush toxins and heavy metals from the cells, easing muscle pain and helping the body to eliminate harmful substances.
Improve nerve function by regulating electrolytes. Also, calcium is the main conductor for electrical current in the body, and magnesium is necessary to maintain proper calcium levels in the blood.
Relieve stress. 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 brain that creates a feeling of well being and relaxation.
While increasing magnesium levels, Epsom Salt also delivers sulfates, which are extremely difficult to get through food but which readily absorb through the skin. Sulfates, which are minerals, serve a wide variety of functions in the body, playing a vital role in the formation of brain tissue, joint proteins and the mucin proteins that line the walls of the digestive tract. Sulfates also stimulate the pancreas to generate digestive enzymes and are believed to help detoxify the body's residue of medicines and environmental contaminants.
