The majority of the population are magnesium depleted. Our Magnesium cream allows natural elemental magnesium to be absorbed directly through our skin. Muscles need magnesium to function properly and Napiers cream allows magnesium to be applied topically for maximum benefit. Studies have also shown that magnesium application can improve both sleep quality and duration. This all natural cream utilises ultra pure Zechstein magnesium chloride, delivering 500mg of magnesium chloride per 5ml usage (providing 60mg elemental magnesium). \nZechstein magnesium is harvested from a primordial sea over 250 million years old and untouched by human activity and pollution.\nNapiers has been a natural apothecary in the UK since 1831.  \nMade in the UK","images":["https://cdn.shopify.com/s/files/1/1328/2787/files/sleepcream.jpg?v=1740176788","https://cdn.shopify.com/s/files/1/1328/2787/files/sleepcream4.jpg?v=1740176788","https://cdn.shopify.com/s/files/1/1328/2787/files/sleepcream3.webp?v=1740176788","https://cdn.shopify.com/s/files/1/1328/2787/files/sleepcream1.webp?v=1740176788"],"price":28,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:43:45.891Z"},"share_url":"https://firestarter.network/l/lst_T8ymnhE_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
