Mag-On Magnesium Supplement (8-Pack & 30-pack)
A Magnesium Supplement for Pre-Race Cramp Prevention Measures
Take this powdered magnesium lemon-flavoured supplement in the morning, one day before your big training day or race.
You Need More Than Sodium
Even if you eat magnesium-rich foods on regular basis, it is difficult to keep a high level of magnesium in your body.
Athletes are often deficient in magnesium, which helps smooth muscle contraction and nerve signal transmission.
Regular magnesium intake regulates smooth muscle contraction even at the last part of your race.
Mag-on's magnesium supplement contains 200mg of magnesium per sachet, using a unique high quality Japanese domestic water-soluble magnesium.
