Oral magnesium supplements typically use magnesium oxide — the form with lowest bioavailability (approximately 4% absorption). Transdermal magnesium chloride bypasses the digestive process. No synthetic fragrance, no synthetic preservatives, no fillers. Featured in Healthline, Marie Claire, and Vogue.
✦ Ingredient Spotlight: Transdermal Magnesium
Over 50% of Western adults are estimated to be magnesium-deficient. Oral supplements have poor gut absorption. Transdermal application bypasses the digestive system entirely, delivering magnesium directly into tissue. Magnesium is essential for over 300 enzymatic reactions including cortisol regulation, GABA receptor function, and muscle relaxation.
Spray 5–10 pumps onto legs, abdomen, or shoulders. Massage gently. Allow 20–30 minutes to absorb. A mild tingling sensation is normal and indicates absorption. Use before sleep for best results.
