Pure Magnesium Oil vs. lasted 24 Months - tested, Miners vs. Seabed, big spray, use case, trending... choice $40 – Excerpt We’ve tested magnesium oils before, but the Seven Minerals spray stands out. At $40, the 12-ounce bottle lasts 24 months—a testament to USP-grade purity and Ancient Underground Permian Seabed sourcing, free from trace minerals. Unlike conventional sprays, ours skips the miner-added fillers, focusing purely on USP magnesium. The ultra-concentrated formula means our sprays go further, though we wish the ancient seabed bit sounded more thrilling. Its size reduces waste, while the free eBook guides us on maximizing benefits. We appreciate transparency but wish the why behind the seabed was clearer. Still, for a big spray that lasts a year, it’s hard not to recommend—especially when better trace-minimum options are far pricier. Our choice? Convenient and undeniably long-lasting (100 words).
