Our magnesium is naturally-sourced from the Zechstein Seabed, which is the purest and highest concentrated magnesium on Mother Earth. 100% Natural. Small batch. Made in USA. No fillers or artificial fragrances. Highly concentrated. Packaged in glass. Cruelty Free. Vegan. Use: Apply generously on clean skin daily for cumulative results. Spray anywhere on your body - pulse points, fatigued muscles, abdomen, and hips. Spray underarms to neutralize odors and to improve lymphatic drainage. Magnesium absorbs almost immediately upon contact. Massaging it into your skin will speed up the rate of absorption. If you are deficient in magnesium you might feel a stinging sensation the first few uses. You can neutralize this sensation by applying coconut oil afterwards if needed. For children, spray only the bottoms of the feet. ** First time orders receive a free wood POS stand with information card** Thank you for shopping small and supporting a woman owned business.
