Magnesium Oil Spray - Premium USP Grade

Magnesium oil can cause temporary itching or tingling due to its high concentration interacting with nerve endings at the skin's surface. This sensation is usually stronger if you are magnesium deficient or have very dry or sensitive skin and often lessens with regular use. The tingling typically decreases as your body's magnesium levels improve.

Individuals with kidney disease, heart block, or low blood pressure should consult their healthcare provider before using magnesium products. Pregnant or breastfeeding individuals and those taking medications should also seek medical advice before use.

For sleep benefits, spray magnesium oil on the soles of your feet, legs, shoulders, or abdomen 20-30 minutes before bedtime. The soles of feet are particularly effective and tend to cause less tingling. These areas allow for good absorption while promoting relaxation.

Many people use magnesium oil as part of a relaxation routine, applying it to pulse points (wrists, inner forearms, temples, neck) or legs and feet. While magnesium supports normal nervous system function, it is not a treatment for anxiety disorders. Always consult your practitioner for medical concerns.

Start with 10-20 sprays per application and gradually increase as your body adapts. Each spray delivers approximately 10 mg of elemental magnesium. Most people use 10-20 sprays once or twice daily. Use our calculator above to determine your ideal dosage.

The skin on the face and scalp can be more sensitive. If you choose to apply magnesium oil there, dilute with water first and perform a small patch test. Avoid contact with eyes and broken skin. Rinse thoroughly to avoid product buildup.

Because it is a concentrated salt solution, magnesium oil can sometimes feel drying or tight on the skin. You can rinse it off after 20–30 minutes and follow with your favorite moisturizer or our Magnesium Cream to help maintain skin hydration while still getting magnesium benefits.

Many people combine topical and oral magnesium. Transdermal application provides localized benefits and bypasses the digestive system. However, total magnesium intake can add up, so introduce changes gradually and consult with your healthcare provider if you're unsure about the right amount for you, especially if you have kidney issues.

An 8 oz bottle contains approximately 1,800 sprays (~225 sprays per ounce). If using 20 sprays per day, one bottle will last approximately 90 days (3 months). If using 40 sprays per day, it will last about 45 days. Use our calculator above to estimate your bottle duration.

Our magnesium oil uses a 1:1 ratio, meaning equal parts by weight of magnesium chloride to RO filtered water. This is the standard concentration for effective transdermal absorption—strong enough to deliver meaningful magnesium (~10 mg per spray) while being practical for daily use. Higher ratios exist but may be too strong for sensitive skin.

While you can make magnesium oil at home using our Magnesium Chloride USP powder, our ready-to-use spray offers: consistent 1:1 concentration, convenient spray application, proper formulation balance, and no mixing required. Both use the same high-quality USP grade magnesium chloride from the Dead Sea.
