Highly concentrated magnesium (90,000 mg / L). First and only liquid magnesium additive that does not contain ammonia. ions restores magnesium due to its exceptional concentration (90,000 mg / L). ions is fully dissolved and without the addition of ammonia. Other liquid magnesium supplements inherently contain ammonia because the magnesium chloride used in their production contains it. aquavitro has gone to great lengths to eliminate this contaminant and a proprietary process makes ions the first and only liquid magnesium additive that does not contain ammonia.
