Ancient Minerals Magnesium Oil Ultra Spray Refill 33.8 oz — Zechstein Magnesium + OptiMSM, Fast-Absorbing

Ancient Minerals Magnesium Oil Ultra with OptiMSM is a topical magnesium chloride spray — a water-based, non-greasy formula combining pure Zechstein magnesium with OptiMSM for daily dermal application.

This 33.8 oz refill supplies a high-purity magnesium chloride solution sourced from the protected Zechstein seabed, blended with OptiMSM (methylsulfonylmethane) to create a lightweight spray that absorbs readily into skin. Designed for easy use in morning or evening routines, the refill format minimizes packaging waste and keeps your favorite topical mineral solution on hand for regular use.

How does this product fit into a daily skin and body routine?

Use the spray whenever you want a quick, residue-free application of magnesium and MSM that dries quickly on skin. It's formulated to be applied to arms, legs, feet, or torso so you can target areas that feel tense or dry without a greasy finish.

• Water-based spray for fast absorption and minimal residue
• Suitable for use after showering or before bed
• Large refill bottle simplifies replenishing smaller spray containers

What makes Ancient Minerals’ magnesium source special?

The magnesium chloride in this formula is harvested from the Zechstein seabed, a deep, protected deposit known for its low contamination and high mineral integrity. The result is a raw mineral base that arrives largely unaltered from its geologic source.

• Zechstein-sourced magnesium chloride for established purity
• Extracted from deep geological layers protected from modern pollutants
• Processed to preserve mineral composition before blending with OptiMSM

Why is OptiMSM included, and how does it affect the formula?

OptiMSM is a branded form of methylsulfonylmethane, an organic sulfur compound commonly used in topical formulations for its skin-compatible properties. In this spray it complements magnesium chloride, creating a combined elemental blend designed to feel light on skin and support routine topical application.

• OptiMSM provides organic sulfur that mixes cleanly with magnesium chloride
• Helps maintain a lightweight, non-greasy texture for easy application
• Formulated to be gentle for regular, targeted topical use

How should I use the refill and store it safely?

Transfer the refill into a smaller spray bottle if you prefer a travel-size or pump applicator, taking care to avoid contamination. Store the full container in a cool, dry place away from direct sunlight and secure the cap to prevent spills.

• Pour into a clean spray bottle for daily use
• Avoid introducing water or other ingredients into the refill container
• Keep capped and stored at room temperature away from sunlight

Who is this for: This 33.8 oz refill is aimed at people who prefer topical mineral routines and want a larger, economical supply of a Zechstein-sourced magnesium chloride blended with OptiMSM. It fits those who use topical magnesium regularly — athletes, active adults, and anyone who favors an easy, non-greasy spray for targeted skin application — and who appreciate a refill format to reduce single-use packaging. Not intended for ingestion; follow label directions for topical use only.
