Magnesium Topical Spray 12oz by Allergy Defender

USP grade, or United States Pharmacopeia grade, refers to products that comply with or surpass the standards established by the United States Pharmacopeia and National Formulary (USP-NF). Fit for use in food, drugs, and medicines. And subject to stringent testing and are typically required to have the highest level of purity.

No — it’s completely fragrance-free, perfect for sensitive households.

Tap or distilled water both work great.

Most customers get 6+ months of nightly use.

Our spray contains only pure USP-grade magnesium chloride and water — nothing else. Because it’s a clean, concentrated mineral, some customers notice a brief tingling sensation on the skin. This is common and typically fades with continued use. If it feels too strong at first, simply dilute the area with a little more water.

Magnesium is perfect for most people, but there are a few cases where caution is advised.

Magnesium can interact with certain medications, such as antibiotics or drugs for heart conditions. Check with a doctor if you're taking regular medications.

Those with kidney disease or impaired kidney function may have difficulty processing magnesium, leading to potential imbalances.

Epsom salts and Magnesium spray both deliver magnesium but differ in use and benefits. Epsom salts, made of magnesium sulfate, are ideal for full-body relaxation. Magnesium spray, containing magnesium chloride, absorbs quickly through the skin for targeted relief, making it perfect for muscle cramps, tension, and replenishing magnesium levels on the go and so much more. While Epsom salts are great for self-care at home, magnesium spray offers a convenient solution for fast, localized benefits.

Topical magnesium is applied directly to the skin in forms like sprays, and is absorbed through the skin into the bloodstream. It's often used for localized relief of muscle soreness, cramps, and tension, and to promote relaxation and improve skin health. Topical magnesium bypasses the digestive system, which can be beneficial for those with gastrointestinal issues and instead absorbed through the skin into the bloodstream.

Magnesium supplements are taken orally as tablets, capsules, powders, or liquids, and are absorbed through the digestive system. They are used to address systemic magnesium deficiencies and support overall health. Oral supplements can sometimes cause digestive issues like diarrhea. The absorption rate can be affected by factors such as the type of magnesium compound (e.g., magnesium oxide, magnesium citrate), presence of other nutrients, and individual digestive health.

Magnesium supplements are an effective way to boost magnesium levels. Since there are various types of magnesium supplements to suit individual needs, we always recommend consulting your doctor before starting or stopping any magnesium product

Many people don't get enough magnesium from diet alone, and modern agricultural practices deplete soil of essential minerals, including magnesium, leading to lower levels in the foods you eat.

Absolutely — while many people use it as a nightly ritual, you can use it anytime you want a grounding, soothing moment.
