Whilst recommended daily magnesium minimum recommended is generally around 300-400mg for adults, there is a wide spectrum of needs for optimal (best) magnesium supply for good health. Some people may need as much as 1,000mg magnesium per day to compensate for excessive magnesium loss or inadequate amount in diet. Read more about dosage here.   For example, if you are young and don’t suffer from too much stress or excessive physical exertion, and if you have a balanced diet of fresh foods and avoidance of chemicals, then 300mg or 400mg of daily magnesium may be sufficient for you to maintain good health. However, if you do excessive exercise or have high levels of stress in your life – such as shift working and sleep deprivation – then you may need 1,000mg per day. We are all different with individual needs, which may also fluctuate daily. If you have a day of physical hard work outside in the hot sun and you perspire a lot, you will have lost excessive amounts of electrolytes in sweat.   Different genetics may need more magnesium than others, people with kidney problems lose too much magnesium in the urine (called hypermagnesuria), and the advancement of age generally means we need extra magnesium for maintenance.   Pregnancy requires a much higher amount of magnesium for the growth of a new body, people with digestive disorders can’t digest and absorb enough nutrients from foods, and there are those who have suffered trauma and injury, which severely depletes the body of magnesium. If you are on drugs or medications, exposed to heavy metals or glyphosate, smoke cigarettes or drink alcohol excessively – all of these circumstances can cause excessive loss or blocking of magnesium in the body.   Regardless of why you have become magnesium depleted, you can recover your stores over time with daily transdermal magnesium supplementation. To optimise results and get the best out of your magnesium, follow a balanced fresh food diet (without processed junk foods and sugar) and drink plenty of filtered water with added magnesium for good hydration, as magnesium makes the water work better.   Recommended Natural Magnesium (chem-free): Natural magnesium chloride hexahydrate salt flakes (food grade) in bath or footsoak, drinking water, plus magnesium skin care using Elektra Magnesium Cream or Magnesium Charge Lotion, with Magnesium Oil Spritz for extra strength as required.
