Magnesium activates over 300 enzyme reactions in the body, translating to thousands of biochemical reactions happening on a constant everyday basis. Magnesium is crucial to nerve transmission, muscle contraction and relaxation, blood coagulation, energy production, nutrient metabolism and bone and cell formation.
Magnesium is required for virtually every biochemical process necessary for life.
Magnesium deficiency is widespread in the western world. In fact, recent studies show that many Americans are magnesium deficient, with some studies placing that number as high as 80% of us being deficient!
Magnesium is a vital component of every living cell.
If magnesium is not supplied in the proper amounts, in the way that nature intended, our bodies suffer and symptoms develop.
Some common symptoms of magnesium deficiency:
● Anxiety and Stress
● Insomnia and poor quality sleep
● Restless Legs Syndrome (RLS)
● Migraine and headaches
● Muscle cramping, spasms and weakness
● Thinning hair and hair loss
● Accelerated aging of the skin
● Increase in the appearance of cellulite
● Abnormal heart rhythms
● Blood pressure regulation

Male and Female age 14+:

Magnesium Overdose Risks:
Overdosing of magnesium through dietary sources is unlikely. Any excess magnesium that is consumed in food will be eliminated in urine.
- Magnesium from supplements can lead to gastrointestinal problems, such as diarrhea, nausea, and cramping.
- Very large doses can cause kidney problems, low blood pressure, urine retention, nausea and vomiting, depression and lethargy, a loss of central nervous system (CNS) control, cardiac arrest and possibly death.
- Anyone with a kidney problems should not take magnesium supplements, unless their doctor advises it.
- Always check your prescriptions and supplements for interactions with magnesium.
