High Strength Magnesium Body Spray For Joints, Muscles & Sleep 
Napiers Magnesium Oil Spray is a high-strength, clean magnesium chloride solution delivering fast, targeted transdermal magnesium direct to muscles, joints, and skin. Just two ingredients: ultra-pure Zechstein magnesium chloride and deionised water. No preservatives, no synthetic additives. Developed in our Edinburgh dispensary. Made in the UK by Napiers the Herbalists — Scotland's oldest herbalist, established 1860.
Magnesium insufficiency is common across the UK adult population. Low magnesium shows up as muscles that stay tight after rest, joints that ache, tension that builds without resolving, and difficulty switching off at night. Topical magnesium addresses this directly, absorbed transdermally, bypassing the digestive discomfort that affects many oral supplement users. Napiers uses Zechstein magnesium chloride, sealed beneath rock for over 250 million years and untouched by modern contamination. Ten sprays deliver 200mg of pure elemental magnesium. Some tingling on first application is natural and indicates rapid absorption.
