New Era No.8 Mag Phos contains magnesium phosphate as its single tissue salt. In tissue salt use, mag phos is the mineral most commonly associated with cramp, spasms, shooting pain and muscles that are tight or knotted. It is one of the most frequently chosen tissue salts for discomfort that comes and goes in waves.
That makes New Era No.8 Mag Phos easy to understand before buying. It is usually chosen when the problem is muscular, spasmodic or crampy rather than inflamed or congested. Magnesium phosphate is the ingredient that gives this product its main purpose.
Mag phos is often discussed in relation to warmth and relaxation in traditional tissue salt use, which is one reason it is so often chosen for muscle discomfort and period cramps. If sharp or gripping pain is the main issue, this is the single salt many people start with.
