Ancient-Minerals mag oil is from 250 million year old sea beds. Ever heard of Mineralife MagOil? They Market a brand called Permian minerals, also from 250 million year old sea beds! I have tried their brand and I can NOT tell a diffenence from the Ancient-Minerals brand.I have tried some of the other ocean based brands and nigari, I can tell a significant difference.
Mineralife sell a whole line of ionic minerals, not just magnesium oil. The price looks good to me?
