Hi Proud Canadian!You too eh? Having trouble finding the purple box? I went through this awhile back and got totally panicked! When it became obvious to me that the purple box was not going to be available for some time (I was calling the manufacturer and it was delayed), I decided to try the pink box. What I did was take one of "each" per day and much to my amazement, I found that I did even BETTER when mixing the two. Now that the purple box is available in my area again, I still take both the pink and purple Caltrates. Still doing okay that way. Haven't tried JUST the pink though so can't say how that would work for me... But I'd give it a go if I were you, until the purple box becomes more readily available. Good luck!
