Buy peter gillham's natural vitality : calmag orange, 8 oz

Calmag orange

Use this formula only when a person fails to get results from 
Natural Calm or Cal Mag Plus. This formula is best suited to 
anyone who does not have a magnesium deficiency (already 
corrected) but has a calcium deficiency. A calcium deficiency 
can create similar symptoms. Remember, for some people, taking 
magnesium too long exclusively, may create a calcium deficiency. 
Again, even with CalMag, always be alert to any symptoms 
appearing when it comes to long-term use. For some people this 
formula, used too long, could create calcium excess again, so 
check periodically, to see if an occasional switch to Natural 
Calm is necessary.
