Transdermal magnesium therapy represents the fastest & most absorbable way of supplementing this essential mineral. Magnesium is absorbed directly into the skin tissue, entering the cells immediately, in the form our bodies are most used to. Magnesium Oil efficiently replaces magnesium lost through modern diet & pressured lifestyles, helping to tackle the problem of magnesium deficiency. The salt structure from the oil provides the most absorbable source of elemental magnesium, mined from natural sea deposits one mile underground & uncontaminated by man-made pollution. Better You™ Magnesium Oil uses a super saturated magnesium chloride, solutioned mined in Northern Europe from the ancient Zechstein sea mineral deposits, one mile below the surface of the earth. Other sources of magnesium chloride are farmed from open seas & unfortunately contain a growing amount of heavy metals, toxins & pollutants absorbed from over one hundred years of industrialisation. Zechstein Inside® Magnesium Chloride has remained protected from man-made pollutants for over 250 million years & is considered the benchmark for pharmaceutical grade magnesium. This is why we are proud to supply notable institutions such as Great Ormond Street Hospital & The Royal London Hospitals as well as GPs & practitioners worldwide. Magnesium Oil Original spray is non-greasy & quickly absorbed to give fast acting relief. Each bottle contains up to 800 individual sprays. Suitable for vegetarians, vegans, coeliacs & diabetics. Better You does not support animal testing.
