Magnesium Oxide Powder 60% - Fine White Powder

At 60% elemental magnesium, one scoop (holds 14.7 cc, equivalent to one Tablespoon), provides 10 grams (10,000 mg) of magnesium. Since is it a fine, white powder, it is best added to moistened feed, to avoid respiratory problems.

Magnesium is beneficial for muscle twitching and spasms, as well as behavioral issues attributable to inadequate amounts of magnesium in the diet.

Other Beneficial Magnesium Combinations

  • When combined with thiamine (vitamin B1) it has a beneficial effect on the nervous system, creating a calming effect -- consider MMX for this magnesium/B1 combination.
