NOW Foods Magnesium Topical Spray provides a convenient transdermal magnesium delivery method — bypassing the digestive system to deliver magnesium chloride directly through the skin to underlying tissues. Transdermal magnesium is particularly popular among athletes for targeted muscle recovery, those with GI sensitivity to oral magnesium, and individuals needing rapid replenishment. Apply directly to muscle areas experiencing cramping or tension, or to the soles of the feet before bed for systemic magnesium support and improved sleep. NOW Foods uses high-quality magnesium chloride in a clean spray formula free from artificial additives. An excellent complement to oral magnesium supplementation, or a standalone option for those who cannot tolerate oral forms.
