Should I continue using other magnesium supplements orally if I am also using Ancient Minerals topically?

This is a matter of personal choice, often dependent on how well or how poorly each individual tolerates oral supplements.
Ancient Minerals topical magnesium represents a welcome alternative:

For those who prefer to avoid the inconvenience of taking pills.

For those who experience loose stools, diarrhea or GI upset when taking oral supplements

For those who do have limited tolerance, Ancient Minerals provides much needed additional magnesium without side effects.
